Best Practices for Continuous Testing in DevOps
Continuous Testing in DevOps is an absolute must. This is required since the software is frequently being released to production; hence it is critical to ensure that the software is of optimum quality throughout the development. Therefore, testing early and testing often are crucial aspects in today’s day and age. For this purpose, QA must get exact requirements, to begin with, and test throughout development and not just before the release.
When it comes to achieving Continuous Testing, test automation beats manual hands down. When the testing process is automated, the risk of human error is considerably reduced. Test automation not only enhances test accuracy and software quality but also safeguards the flow throughout the system. It was for this purpose that continuous testing tools were introduced.
There a few practices which when implemented aid the process of continuous testing in DevOps. Here a few of them:
1. Decide What to Automate
Automation scripts should ideally be created for repetitive tests that need to be executed with each release, like regression cases. This is because these kind of tests are time-consuming and challenging to conduct manually. The aim is to simplify repetitive tasks and allow manual testers to focus on ways to improve product quality.
2. Choose the Right Continuous Testing Tool
The continuous testing tool must be congruent with the technology used by your application. Know the browsers the app supports; the technology it uses and the language it is built on. Choose a tool that is easy-to-use and does not require heavy time investment in learning the technology. The tool should help in the execution of multiple test cases without any intervention and should generate accurate logs at the end of the tests.
3. Create Reusable and Maintainable Automated Tests
A good continuous testing tool must support changes in the tests. While creating the test scripts, consider the possible future alterations that may happen in the application. Adopt a process of designing modular scripts that are less dependent on one another.
4. Avoid GUI Automation
As the development project advances, the UI of an application is prone to changes. Relying heavily on UI makes automated tests slow and increases the risk of errors. For this reason, it is vital to make your automated tests resistant to UI changes, to ensure that your scripts work on future versions of the applications. Therefore, it is crucial to avoid automating the GUI.
Continuous testing in DevOps plays a vital role in the success of any software development project. Incorporating constant feedback is critical while attempting to improve quality. Adequate planning and investment in the use of continuous testing tools can significantly add to the quality of the software, and also reduce the time taken to release products. Additionally, the right continuous testing tool also ends up increasing the productivity and effectiveness of QA teams. The guiding principles of DevOps such as test first, clear communication and coherency in collaboration can help resolve QA challenges and also facilitate QA teams to take their deliverables to the next level.
