Agile testing is based on short development cycles which help in making the test automation more effective and efficient. Agile Test Automation bolsters quality assurance and quickens application delivery.
Some of the principles of agile test automation can be listed as follows:
Coverage based automation: The amount of code that has to be covered derives the scope of test automation that would be required. Test automation runs based on code-coverage quite easily explain the test traceability.
System level automation: If there is an agile workflow in place, the UI will experience multiple versions and changes on a regular basis; this also depends on the team input and the user feedback. When the automation is conducted on the UI level, it is a time consuming process as the UI has multiple versions. Hence, to avoid this, keep the maintenance costs low and to boost the overall coverage the automation must be conducted at the level of systems and services.
Test driven by development teams: The testers develop the test along with the product development teams. They design the automation tests in the initial stages and then make them the foundation for the source codes. Hence, there is a major requirement of persistent collaboration between different product development teams.
Automated testing over manual: The manual testing was very prominent in the earlier stages and then at least a round of manual testing was important as the automated testing boomed. But now with the fast pace of the market and the stern demands, there is minimal manual testing. Automated testing saves time and makes the whole process easier; hence teams now directly dive into automated testing and do not include much of manual testing.
Choosing a tool: This is a highly pivotal decision to take for the testers, the wrong choice could lead to major effects on the functioning of the company and would require a long time to be fixed. Hence, selecting the right tool becomes absolutely important for the testers to ensure successful test runs. They need to consider multiple factors while choosing the tool like, integration capabilities, installation requirements, overall cost, maintenance, and compatibility with the testing environment.
Verifying test automation code: In an agile software testing workflow, the need for the code to be flawless is very high with regards to the pressing lack of time. The code has to be tested before the tests are run. The team must check the high quality and the consistency of the code; the code must be verified on all ends. The code must have low maintenance cost, reliability and robustness. The test automation process demands the steps to be taken in a sequential flow, this means that the automation program is handled by a single tester and he must take care of each step.
Sharing code across teams: The development, building and operations team in a company must be ideally kept in the loop with regards to the use of any new automation code. It increases the basic focus in product quality and enables smaller test as teams are aware of the processes. Also, the teams that are not from the coding background should have an idea of the tests and it gives them some set of approaches for dealing with these issues.
