CI/CD Pipeline: Demystifying The Complexities

February 19th, 2024 by

Industry leaders consider CI/CD to be an essential part of the app development cycle as enterprises are keen to reduce the time to market. Continuous integration and continuous delivery help in improving and enhancing the quality of the product while reducing the cost of the project. This blog will help you understand the of a functioning CI/CD pipeline, its challenges, and its benefits. Before we get into the details, let’s have a look at the basic terminology.

  • Continuous Integration

Continuous integration (CI) is a software development practice where developers frequently make changes in the code and add it to the central repository after which automated tests are run. CI is the integration stage of the software release process which depends on automation and constant integration. The main goal is to find the bugs and resolve the issue quickly to improve the software quality and reduce the time to market.

In continuous integration, developers focus on smaller commits several times a day. Developers pull the code from the repository before pushing it to the build server where the build server runs various tests to verify the code commit.

  • Continuous Delivery

Continuous delivery is a software development practice that ensures a faster and stable release of the changes in the code. In this, the changes are automatically built, tested, and prepared for production release. The code changes are deployed to a testing environment or a production environment after the build stage is completed. When continuous delivery is implemented, developers always have a deployment-ready build artifact that has passed through a standard test process. In continuous development, the code revisions to a production environment automatically which allows for a continuous feedback loop early in the development cycle.

  • Continuous Deployment

Continuous deployment is a bit similar to continuous delivery but is a step further towards process automation. The change that passes through all the production stages is released to the client directly without the need for any human intervention. Continuous deployment accelerates the feedback loop as only a failed test will stop the change from getting deployed to production.
Continuous Deployment

  • Continuous Testing

It is the practice of executing automated tests throughout the software development life cycle. Instead of the old testing method where testing occurs at the end of the software development cycle, CT occurs at multiple stages, including development, integration, pre-release, and in production. It is done to ensures that bugs are caught and fixed at the earlier stages in the development process, saving a significant amount of time and money.

continuous testing

While building an application that will be deployed on the live servers there will be a team of developers responsible to write the code. The developers commit the code into a version control system like Git, from where it goes to the build phase. The built is then sent to the next phase with a proper version tag.

For instance, you have a code that needs to be compiled before execution. When the code enters the built phase, all the features of the code are merged from various repositories and compiled using a compiler.

The next phase is the testing phase where various types of testing are performed. Sanity testing and unit testing are the most crucial part of this process as individual units of the built are tested to check if they meet the requirements.

The builds are moved to the deployment phase after passing the test and then pushed into a test server. Here developers simulate the product in a production-like environment to examine the features.
What is a CI/CD Pipeline?

Before the build features are deployed to production, the automation test phase will perform the final tests to qualify the features. continuous testing is implemented in this phase to ensure there are no bugs remaining.

In case there is an error at any stage of the CI/CD pipeline, feedback will be sent to the development team so that issues are addressed immediately. Thereafter, code changes will go through the production pipeline once again.

In the final phase, the code is moved to the production server after code passes all the tests. The constant feedback loop helps make the CI/CD pipeline a closed process where builds are continuously committed, tested, and deployed to production.

Challenges in CI/CD Pipeline

Limited environments

During the CI/CD pipeline implementation, a limited number of shared test environments increases the risks of a bottleneck. You would need to reserve an environment to avoid multiple CI/CD pipelines running side by side from attempting to deploy and test in the same environment. One of the leading causes of deployment failures is misconfigured environments modified by previous teams or test runs.

Security and Ownership

Sometimes it’s difficult to know who needs to fix the pipeline when the stages fail as delivery pipelines span multiple teams in an organization. An owner has to be assigned at every stage of the CI/CD pipeline who will be responsible to fix the issues and ensuring that the delivery runs smoothly. The owner will also contribute to the feedback-driven improvement of the pipeline.

The orchestration tool used by the team should have an effective security model that could provide better visibility into the state of the entire CI/CD pipeline. For instance, to identify the causes of test failure, the team would have to examine the result of the test phase. But they should not be given permission to modify or disable the configuration of that test step.

Managing multiple custom CI/CD pipelines

There will be multiple CI/CD pipelines in large organizations as they have diverse portfolios spanning different departments, technology platforms, and customers. It would be difficult to analyze metrics like throughput, successful execution, and cycle time if every pipeline ends at different stages in the delivery process. It’s easier to manage a large set of CI/CD pipelines if each one is based on a standard template. This will help in meaningful comparative reporting and it will provide useful feedback to improve other pipelines.

Massive applications

Large apps with several components that need to be compiled, tested and deployed are tough to update incrementally which leads to long testing and deployment cycles. It’s harder to perform quality control and root cause analysis as multiple teams commit several changes at the same time. It’s difficult to create a standardized delivery pipeline as the release process needs to differ slightly. Teams often initiate a workstream to incrementally break out components of the app into different modules so that they can be built and deployed separately, allowing for faster feedback cycles with smaller sets of code changes.

Complex Branching Strategies: Navigating complex branching strategies can be a significant challenge in CI/CD pipelines. Without a clear and consistent strategy, such as GitFlow or trunk-based development, teams may struggle with merge conflicts, delayed features, and integration issues. Establishing a streamlined branching strategy that aligns with the CI/CD objectives is crucial for minimizing integration headaches and facilitating continuous integration.

Handling Dependencies: Modern applications often rely on numerous external libraries and services. Managing these dependencies can become a challenge, particularly when updates to dependencies break the build or introduce vulnerabilities. Effective dependency management tools and practices, such as semantic versioning and automated dependency updates, are essential to maintain the stability and security of the CI/CD pipeline.

Flaky Tests: Automated tests are the backbone of CI/CD pipelines, ensuring that code changes do not introduce regressions. However, flaky tests, which produce inconsistent results, can undermine confidence in the build process. Addressing test flakiness requires a disciplined approach to test writing, including isolating tests from external dependencies and ensuring that tests are deterministic.

Scaling the Pipeline: As projects grow in complexity and team size, scaling the CI/CD pipeline can become a challenge. Issues such as increased build times, resource contention, and the management of parallel jobs need to be addressed. Techniques such as build matrix reduction, parallel test execution, and the use of scalable cloud resources can help maintain pipeline efficiency at scale.

Third-Party Integrations: CI/CD pipelines often integrate with various third-party services for code analysis, deployment, monitoring, and more. Managing these integrations, especially when dealing with API rate limits, service downtimes, or incompatible updates, requires careful planning and fallback mechanisms to ensure the pipeline’s resilience.

Avoiding Configuration Drift: Ensuring consistency across development, testing, staging, and production environments is crucial. Configuration drift, where environments become inconsistent over time, can lead to “works on my machine” issues and deployment failures. Infrastructure as Code (IaC) tools and practices can help mitigate this risk by codifying environment configurations and making them part of the version-controlled repository.

Skill Gaps: Implementing and maintaining a CI/CD pipeline requires a broad set of skills, including coding, automation, infrastructure management, and security. Talent gaps in these areas can hinder the effectiveness of CI/CD initiatives. Continuous learning and cross-training, along with the hiring or consulting with experts, are strategies to overcome these challenges.

Why CI/CD matters

CI/CD provides several benefits for your software development team including improving developer productivity, automating the process, improving code quality, and delivering updates to your customers faster. Let’s have a look at some more benefits of implementing a CI/CD pipeline.

Improve Developer Productivity

CI/CD practices enhance your team’s productivity by freeing developers from manual tasks, working on complex dependencies, and returning focus to delivering new features. Instead of integrating their code with other parts of the business and spending time on how to deploy this code to a platform, developers can focus on coding logic that delivers the features you need.

Automated Software Release Process

Continuous delivery provides a method for your team to check-in code that is automatically built, tested, and prepared for release to production so that your software delivery is efficient, resilient, rapid, and secure.

Improve Code Quality

CD can help you discover and address bugs early in the delivery process before they grow into larger problems later. Your team can easily perform additional types of code tests because the entire process has been automated. With the discipline of more testing more frequently, teams can iterate faster with immediate feedback on the impact of changes. This enables teams to drive quality code with a high assurance of stability and security. Developers will know through immediate feedback whether the new code works and whether any breaking changes or bugs were introduced. Mistakes caught early on in the development process are the easiest to fix.

Deliver Updates Faster

CD helps your team deliver updates to customers quickly and frequently. When CI/CD is implemented, the velocity of the entire team, including the release of features and bug fixes, is increased. Enterprises can respond faster to market changes, security challenges, customer needs, and cost pressures. For example, if a new security feature is required, your team can implement CI/CD with automated testing to introduce the fix quickly and reliably to production systems with high confidence. What used to take weeks and months can now be done in days or even hours.

In a Nutshell

Continuous integration and continuous delivery is an ideal solution for an organization’s app development teams. Developers just need to push the code to a repository. The code will be integrated, tested, deployed, tested again, merged with infrastructure, go through security and quality reviews, and be ready to deploy with extremely high confidence. A CI/CD pipeline helps improve code quality and software updates are delivered quickly.

How Continuous Testing in DevOps enables quality in the CI/CD Pipeline

July 16th, 2020 by

We all understand the importance of software testing and how it transforms the goodwill of the business by enabling delivery of quality product to its clients in shorter delivery cycles. It becomes challenging to run the test cases manually by evaluating the quality of each line of code at every step of the continuous Delivery process. This is where Continuous testing in DevOps comes into picture.

Continuous testing in DevOps Pipeline

 
In traditional ways of testing the software used to pass through different development and QA phases which took more time until the final delivery of the product. According to a research by Gartner, Continuous testing in DevOps is aimed at providing early and quick detection of signs of risks related to the product release. DevOps Continuous Testing is an inevitable activity of the delivery process rather than just a mere stage in the delivery process. The main purpose is to inculcate quality into the CI/CD pipeline by utilizing the key benefits of continuous testing in DevOps.
 
Continuous Testing in DevOps
DevOps Continuous testing is a critical aspect responsible for seamless Continuous Delivery. It involves the usage of agile development methods and processes into the QA process further providing a productive testing process.
 
Here are a few points to understand the benefits of Continuous testing in DevOps at the deeper levels:
 
a. Provides Sustained Risk Analysis:
 
There has never been any code build that is error free and in a ready-to-release form. Even if the final release candidate has come without any glitches, passes all the tests, it has to be ‘prepared well’ for the final release and approved by the business leaders. Continuous Testing evaluates the code at a deeper level to estimate all the possible risks connected to it so that a corrective action could be taken at the right time without breaking the ‘continuous delivery’ chain.
 
b. Cuts down the feedback cycle:
 
The key benefit of continuous testing is that it evaluates the code layer by layer at each stage of delivery pipeline, allowing testers to understand the source of the problem. The actionable insights helps the QA team to act on time and avoid longer queues
 
c. Broader Test Coverage:
 
A broad range of tests can be applied throughout the testing process with the help of continuous testing tools for DevOps such as Selenium, etc. It covers both functional and non-functional testing types to increase test coverage by emulating testing like cross-browser testing, API testing, regression testing, integrated testing, unit testing and non-functional testing like security, reliability, scalability, usability and many more.
 
d. Delivering High Quality Product:
 
‘Test-early-test-often’ is the key mantra of continuous testing which is self explicable. In order to ensure delivery of high-quality product to the end user, there needs to be a process to continuously monitor the progress along the entire delivery pipeline. Achieving high product quality is the result of continuous testing that strives to finding and addressing risks effectively and by gaining feedback at the early phases of software development lifecycle.
 
e. Faster Software Delivery:
 
The whole point of introducing Continuous Testing in DevOps is to speed up the product delivery cycle. Following a multi-point testing at different stages allows the QA team to detect the glitches early and take quick corrective actions so that the final delivery is not impacted.
 
f. Easy Integration with the DevOps Process:
 
Continuous testing seamlessly integrated with the DevOps process right from the early stages of the development process rather than functioning just before the release. Continuous integration into the software pipeline enables quick fixes so that the development process can be aligned with the business requirements on time.

Tools for continuous testing in DevOps

 
For a seamless experience in the entire CI CD process, Continuous testing has to be supported by the best tools for continuous testing in DevOps. For performing smooth Continuous Testing, the Automation Framework has to be integrated with the CI tool, version control and various automated continuous testing DevOps tools to execute different types of testing at various stages of the process. For example, :
 

  • Using Selenium for performing functional testing
  • Load runner for performing load testing at its best,
  • Secure code analysis using Fortify and static code analysis using Sonar, etc.

 
Apart from these there are many other trusted DevOps Continuous testing tools available in the market for an efficient continuous testing, like JIRA, Jenkins, Bamboo, Docker, Appium, SoapUI, PagerDuty, CodeCluster etc. The concern is that not all the tools support comprehensive automation solution. Some organizations prefer to create self-made automation frameworks depending upon the version control used to enable complete automation of the CD pipeline.
 
Since Continuous testing is the most critical aspect to be covered by the business in order to achieve quality product release, it has to be backed by the choice of right, suitable tools and frameworks to achieve speedy and quality delivery.

Challenges in DevOps Continuous Testing and how to overcome them

 
Even after understanding the advantages of adopting continuous testing in the DevOps process, many organizations face the challenges of successful implementation of it. Establishment of an efficient automation framework is a daunting deal as it involves a huge investment, expertise and effort. Moreover, the organizations are not equipped with the scalable infrastructure to run tests continuously. Also, without a strong coordination among the product, development and testing team, this seems even tougher. Although there are challenges in successful adoption of Continuous testing, with a little sensibility one can overcome it. Here are a few of the key points to comply in order to overcome the challenges :
 

  • By proper team engagement, the cultural and communication barriers can be dealt with enabling the SDLC team to have better coordination, collaboration and understanding of the scenarios.
  • Reducing unnecessary and extensive testing plans, the focus should be on keeping it simple and logical. Instead, the energy could be diverted to more important test objects in order to create much better measurable results.
  • Automation would ease the successful implementation of continuous testing in DevOps. Well, complete automation isn’t achievable but more the process automation, easier it becomes to carry on the continuous testing.
  • Carry out testing at all stages of production and QA environment would continuously providing feedback to developers to improvise on the product quality.
  • Last but not the least, implementing artificial intelligence and other intelligence programs for problem solving and to think beyond automation at every stage of delivery would boost up the SDLC.

 
By now we all know how significant continuous testing in DevOps for any business. It essentially brings together all the stages of designing, developing and deploying the software. Merely providing a software product does not help but providing best products faster than the competitors would be the key differentiator of your business. If practiced earnestly, it provides consistent insights about the software development to ensure speedy delivery.

8 Tips to Optimize Your Continuous Testing Strategy

July 13th, 2020 by

In this competitive digital era, there has always been a constant demand for continuous digital improvement. Even if automation is a prominent keyword nowadays, a recent report says that only 30% of the organizations have adopted automation testing. Although the organizations invest a considerable amount of time and money in transforming their development processes, they fail to reap the benefits of the shift in the right direction by choosing only a few aspects of testing.
 
Change is inevitable in the software development lifecycle and in order to go hand in hand with the ever-changing dynamics and produce high-quality software, it is important to rely on implementing an effective Continuous testing Strategy. The development teams have to be focused on optimizing the delivery cycles and provide uninterrupted business experience.

What is continuous testing?

 
Continuous testing is a type of testing in which involves evaluating the quality of software often at multiple stages of the continuous delivery process for early detection of errors ultimately providing quality software and business continuity. It involves testing in multiple developments and QA phases to achieve continuous quality and improvement. Continuous testing plays a key role in DevOps using automation tools that help developers in getting quick feedback on the defects and make changes accordingly.
 
Continuous Testing Strategy

Challenges to an effective continuous testing

 
Organizations want to frequent deployments but the majority are unable to even reduce their software development cycles because of a lack of effective continuous testing delivery strategy. The success comes when there happens to be a mix of both manual and automated testing consistently throughout the delivery process. It becomes really important to automate every step to move fast in aspects like test design, test orchestration, execution, etc.
 
Test automation strategy is the backbone of the final product that a business delivers. It should be strong and flexible enough to bear the impact of any change and every variable of the testing process. Let’s discuss how optimizing continuous delivery testing strategy helps improving the testing process and to increase the software quality:

1. Thorough Test Automation Plan

 
Research says that the majority of the organizations mostly focus on specific forms of testing. For example, few businesses focus on API integration testing and UI testing and a few focus on both individually. But what they lack is a detail oriented automated continuous integration testing strategy that involves all of the above types of testing. Choosing a specific type of testing is right in some business scenarios but a business should always be equipped with a plan that can accommodate any type of testing which can be used whenever the need arises. The real comparison of continuous testing vs test automation will always persist considering the scale and requirements of the business.

2. Initial Trial and Testing

 
Introducing unreliable and lengthy test cases in the process leads to a huge wastage of time and effort putting the QA teams to get indulged in an ineffectual analysis of each code commit. Instead, the QA teams can do a bit of testing by adding nominal test suites in order to avoid big risks and check its impact along the way. Gradually adding stable test cases. It is important to have more stable test cases than counting how many were executed especially in DevOps.

3. Choosing the best test automation tool

 
Building a comprehensive continuous testing strategy is a mandate but choosing the right test automation tool is of critical importance for achieving complete stability. It is insignificant to even think of a failure caused merely because the test automation tool couldn’t perform on the assigned UI control on the application being tested. The acceptable reason for a failed test could be either bug or design change but not because of an automation tool. A good automation tool would always add value to the organization by activating continuous release and deployment, by reducing time and maintenance costs, by increasing the reusability of the code and by providing a higher return on investment.

4. Modularizing tests

 
In order to handle complex integrated applications, introducing modular testing is the best way to breakdown application functionality. Breaking down the app functionality into modules provides a road map and makes it easier to rearrange the functionality into testing representing different workflows. Amorphous tests can be easily redressed by introducing modular testing and decoupling test data, test flow and element locator mappings.

5. Automated Screenshots

 
When analyzing the test results to find out the causes of test failure, screenshots of the test execution is the best reference in order to dig deeper into the cause of the problem. A reliable automation tool automatically generates screenshots of all important interactions happening during the test run. Screenshot recording is not supported by all the automation tools; In that case, one should reconsider selecting another test automation solution to reap the maximum benefit of this feature.

6. Measuring Test Automation ROI

 
Major trends like Continuous testing, automation and DevOps and demand for faster continuous delivery have raised the standards for quality software so high that everyone is trying hard to stay competitive by optimizing their continuous testing and development strategy, that too while maintaining low costs. In this situation, balancing the test execution costs cannot be ignored. At some point in time, test coverage needs to be scaled up, teams have to opt for cloud usage which is expensive and acts as a major cost burden. The best idea would be to separate high and low level test requirements i.e performing more advanced integration and compatibility tests on cloud and executing the low level tests on-premise to maintain cost balance and getting the best automation ROI.

7. Track and Monitor

 
When the development and operations teams work together, they face many operational challenges. Developers are focused on pushing a new update and testers- on maintaining the reliability of the service delivery. Connecting these two points is challenging and these challenges are overcome by introducing continuous testing and DevOps. In the long run, a business should always invest in a system monitoring tool that will help to detect the causes of the gap and back outs more efficiently.

8. Outsource

 
Outsourcing the QA process extends an additional support system, giving an extra edge in delivering quality service. The veto in the world of continuous testing is that it gives and extra nudge by providing an exposure to the more specialized areas of testing like impact analysis, performance and security testing etc. It acts as a source of energy given to a focused area of the development life cycle. As a result, it becomes a win-win situation for both developers and testers.
 
Continuous Testing and Delivery is not a luxury but a necessity in today’s era. A well designed continuous testing strategy is the foundation of continuous testing and quality service delivery. Although the journey is full of challenges if planned meticulously, the businesses would be able to streamline and reap the maximum benefits of test automation and continuous testing.
