A test automation strategy can become successful and sustainable only when it saves time and resources that were extensively consumed in manual testing. Using automation tools to execute test cases can be beneficial only if regression cases are handled expertly and the functionality of the software is user-friendly. When you develop a range of automated test cases, it is important that they are independent and self-contained so that parallel execution is possible. Here are some best practices for effective test automation.
It is often said that regression tests are the best-chosen cases for automated testing. This is because of the element of repeatability that is inherent in regression cases. If you take the pains in evolving a test automation strategy for a case that is one-time, then the benefits of automation cannot be realized.
Deciding what to automate
It is not practical to automate all test cases. Pick tests that are repeated often and those that are more prone to human error. Tests that are impossible to be done manually or will consume lot of time and money in the process are ideal for automation. Tests that require multiple data sets and those that run on different software platforms and configuration can be automated.
Carry out frequent refactoring
A good automation tester ensures that the codes are refactored on a timely basis. Changing the source code of test scripts helps in improving the internal structure. However, care must be taken not to hamper the functionality or the external behavior of the test code.
Ensure technical fit if the automation tool
Automation tools are important but they cannot cover all aspects of the process. Choosing the right tool is a means to testing automation and not the end. The tool must have a perfect fitment and compatibility with the applications and technologies of your organization. The chosen automation platform must have capabilities to move between technologies if the test cases so require.
Get a dedicated and well-qualified team of automation engineers
The worst mistake in the test automation process is to let manual testers man the process. Automated testing is not an extension of manual testing and it requires completely different skill sets and resources. Test automation required dedicated bandwidth and cannot be allocated to any random tester. Improving readability and simplification of the code structure are ideal for superior performance of test automation.
What transpires from the above analysis is that manual testing cannot be scrapped altogether under the name of automation. Any successful IT organization has at its disposal a productive blend of manual and automated testing. Only then software testing can yield collective success by reducing the burden on the QA to run repeated regression tests. Also, hold back from constantly comparing manual and automated. Both are needed and are ideal in different scenarios.
