How can you automate regression, smoke, and sanity testing of software?

Automate sanity, smoke, and regression testing with tools like Selenium or Appium for UI, and frameworks like JUnit or TestNG for backend. Integrate these scripts into CI pipelines for efficient, continuous testing.

Regression testing is vital to confirm code changes don't introduce new defects. Smoke testing quickly checks basic functionality and stability, serving as a preliminary filter before in-depth testing. Sanity testing is a focused evaluation ensuring software aligns with requirements, allowing for further, more detailed testing. These testing methods collaborate to fortify software quality. Regression testing is a continuous process to maintain integrity as the software evolves. Smoke testing acts as an initial litmus test to spot showstopper issues early. Sanity testing, on the other hand, provides assurance that specific changes or versions adhere to requirements.

Automation reduced our regression testing time from hours to minutes. This not only saved time but also boosted our confidence in software stability during frequent updates. First, selecting the right automation tool is vital. Choose one compatible with your application's technology stack and your team's skills. Identify which test cases to automate, prioritizing critical ones prone to regression. Create adaptable, reusable automation scripts to save time and effort. Effective test data management is key. Maintaining realistic datasets ensures your automated tests uncover real-world issues. Integrating regression testing into CI/CD pipelines is a must. Automation within these workflows catches issues early, enhancing software stability.

Before automating regression test cases an analysis needs to be done to identify for each area of the application what are areas that can be probably impacted. Once this view is in place we can configure our automation framework to trigger impacted regression areas based on the area of the application that was changed. This sort of impacted regression testing can help speed up the test execution timeline for regression itself. Also it is not required to run the full regression suite for every change in the application rather an impacted regression run would suffice.

Automating smoke testing is a valuable asset for ensuring the fundamental functionality and performance of your software. Identifying key test cases that validate core operations, such as login, navigation, and basic data interactions, is essential. Using familiar automation tools like Selenium and continuous integration platforms like Jenkins, our team successfully streamlined the smoke testing process. The beauty of integrating smoke testing into your continuous integration pipeline is that it runs automatically with each deployment, promptly identifying and addressing critical problems. This proactive approach enhances software quality, saves time, and mitigates potential setbacks.

Implementing automated sanity testing within the sprint can be quite challenging. This is because you need to automate features that are being developed in the current sprint. Mocking the backend and automating only the UI is a possible approach, but creating E2E smoke tests for the current features might not be your top priority. It's something you can consider when time allows. Also, It's worth noting that all sanity tests will eventually be added to the regression suite in the future.

Sanity testing can be automated as a strategic way to make sure a new build or version complies with certain functionality and standards. Based on my real-life experiences, the process requires a clear grasp of the build's objectives and expected outcomes. In a recent project, this approach significantly reduced the time spent on sanity testing while improving consistency. It empowered our team to quickly detect discrepancies with the build's goals, enabling informed decisions on whether the software was ready for comprehensive testing. To enhance the process, consider using test management tools such as Jira or TestRail for efficient tracking, documentation, and reporting of sanity test cases and results.

The key challenge lies in balancing the cost and benefit of automation versus manual testing. It's essential to assess the suitability of each test for automation, as some tests may not justify the investment. A well-planned automation strategy can maximize efficiency and reliability in software testing, but it requires a thoughtful approach to navigate the complexities and extract the full benefits of automation.

It's important to highlight that these types of automation tests should be carefully outlined in the Test plan before actual start, Exactly in (Test strategy > Automation strategy ).

Embarking on the automation of regression, smoke, and sanity testing is a valuable endeavor. Here are some practical steps to get started- - Define your automation objectives and identify test cases to automate, prioritizing project needs. - Choose automation tools and frameworks aligned with software and team skills. - Invest in training or use available resources to become proficient with your selected tools. - Start small by automating a few critical test cases, expanding gradually. - Integrate your automation with other tools like continuous integration, test management, and bug-tracking systems. - Continuously assess automation results and make adjustments to test scripts to accommodate software changes, enhancing performance.

To begin, select suitable test automation tools aligning them with your project's requirements. Prioritize and choose test cases conducive to automation, focusing on repetitive and critical scenarios. Create test scripts using your selected tool, which might involve coding/graphical interfaces for recording actions. Ensure your test data and environment closely mirror the production setup, emphasizing effective data management. Introducing CI allows for automated testing triggered by code changes. Utilize version control and robust test reporting to manage scripts and analyze results. Regular maintenance of test scripts is vital to accommodate software changes. Parallel testing can expedite the process.
