Best Practices for Continuous Integration and Continuous Testing

Here are some questions and answer for continuous testing

Q-1 What is Continuous Testing?

In Continuous Testing, development teams actively execute tests continuously throughout the software development cycle, covering various levels of testing, including unit tests, integration tests, and end-to-end tests. This approach enables the early detection and resolution of any issues or bugs that may arise during the development process.

The Continuous Testing serves as a crucial component of modern software development methodologies, seamlessly integrating testing activities into the overall development workflow. By incorporating testing at every stage of the software development cycle, teams can ensure that the software meets quality standards and functions as expected.

Q-2 How is Continuous Testing different from traditional Testing?

Continuous Testing differs from traditional testing in several key aspects.Firstly,it is an ongoing and automated process that integrates testing activities throughout the software development and delivery pipeline. This ensures that tests are executed regularly and consistently, providing timely feedback on the quality of the software. In contrast, conventional testing is often a separate and manual activity conducted at specific stages of the development cycle, which can result in longer testing cycles and delayed feedback.

Secondly, it emphasizes the utilization of automation tools and frameworks to execute tests quickly and efficiently. Automated tests can be run repeatedly and consistently, reducing the reliance on manual efforts and increasing the speed of test execution. Traditional testing, on the other hand, relies more on manual testing techniques, which can be time-consuming and prone to human error.

This ensures that code changes are continuously validated, and defects are identified early. Traditional testing, on the other hand, often occurs as a separate phase after the development is complete or during specific testing cycles, which may result in delays in bug detection and resolution.

In summary, it offers a more agile and efficient approach to software testing. It enables faster feedback, quicker bug detection, and a more reliable software delivery process. By automating tests, testing continuously throughout the development cycle, and promoting collaboration, it helps organizations deliver high-quality software products more efficiently and effectively.

Continuous Testing Process

The code is continuously developed, tested and deployed.

Q-3 How to Perform Continuous Testing?

Performing Continuous Testing involves several key steps. Firstly, establish a comprehensive test strategy that outlines the testing objectives, scope, and approach for the software development and delivery pipeline. This strategy should incorporate automation tools and frameworks to enable efficient and consistent test execution.

This ensures that tests are triggered automatically whenever code changes are made, enabling quick feedback on the quality of the software.

Utilize test automation extensively to automate repetitive and time-consuming test cases. This includes unit tests, integration tests, regression tests, and end-to-end tests. Automated tests can be executed frequently, providing continuous validation of the software and enabling early detection of defects.

Implement a robust and scalable test infrastructure that supports the execution of tests across various environments and configurations. This infrastructure should enable parallel and distributed test execution to optimize testing time and resources.

Leverage Continuous Monitoring and Continuous Feedback mechanisms to monitor the application’s performance, security, and other non-functional aspects. This helps identify any issues or bottlenecks in real-time and provides valuable insights for further improvements.

Agile Teams– Continuous Testing Tools

Katalon Studio:
Katalon Studio is a wrapper on Selenium. This tool offers a complete platform to perform automated testing for Web UI, API, desktop and mobile.

Selenium: 

Selenium is an open-source tool, used for functional automation, supports various browsers and operating systems. As it requires technical knowledge, it is difficult to use. Mobile automation is not supported by Selenium.

Jenkins:
Jenkins is a continuous integration tool based on Java language and is configurable via both GUI interface and console commands.

Benefits of Continuous Testing

• Speed up software delivery
• The Continuous testing enhances code quality
• It helps to evaluate business risk coverage.
• ·       This integrates into DevOps Process
• Helps to form an agile and reliable process in just hours rather months.
• stimulate time-to-market with a continuous feedback structure.
• Automation helps to achieve stability by supporting the same configuration for all appropriate tests.
• Highlight business assumptions to reduce business risks
• Providing global test environment approach with Service Virtualisation

Challenges of Continuous Testing

• ·       Lack of DevOps skills, knowledge, and right tools for testing in Agile & DevOps environments.
• Diverse test environments which are not replica production environment.
• Traditional testing process and imprecisely defined test data management.
• Inadequate and unproductive resources and test environments
• Complicated application architecture and business logic that limits DevOps adoption.

Conclusion:

• The Continuous testing is a activity of testing early, testing often, testing everywhere, and automate.
• The old method of testing the software is handed off from one to another team
• Jenkins, Travis, and Selenium are Famous Continuous Testing and Continuous Integration tools.
• CT delivers continuous feedback as per each phase of the CI/CD pipeline.
• Helps to enhance code quality
