Automated testing is an important process throughout the software development cycle, as it can provide a quick report on the state of the product when adding a new function. Also, automation removes the load from QA, eliminating the repeated start of regression tests, which saves time, which can be used to test other things.
Automation can bring many benefits. Correcting it will improve the quality of the final product. The following tips and best practices will help you with this.
Manual testing against automated
Avoid comparing manual and automated testing. They both need and have different goals. Automated tests are a set of instructions written by a person to perform a specific task. Each time you run an automated test, the steps described in the instructions will be performed and the described checks will be performed. With the automated software testing company this is important.
On the other hand, during manual testing, the tester’s brain is engaged and can detect other system failures. During manual testing, the tester may notice bugs that do not see autotests.
Automation of regression tests
Automated tests are most useful in regression, after each build. If the test will be run only once, then there is no point in writing the autotest. With constant product updates, the regression value will only increase.
Making a test before automating it
The best option is to create a competent test on paper. A well-written script that checks the performance of any module according to the documentation is already half the battle. By automating such a scenario, we get an autotest that completely checks a certain block for compliance with the technical task.
No uncertainties in automated tests
The test should perform a strictly described test script and have a strictly fixed expected result. He must perform a certain set of actions and compare the result with the expected in advance. No more decisions he should not take. If the test passes once, and the next falls, although no changes have been made to the software, then such a test is unstable. If it is impossible to correct an unstable test, it should be removed from the regression. Further analysis of the regression and analysis of such a test will take a very long time.
Check AutoTests for Validity
With any changes in the documentation, make them immediately in the autotests. Running non-valid tests will entail a great waste of time for their analysis.
Do not automate unstable builds
When developing new features, changes are often made to them. They can be caused by business requirements or changes by developers of technologies implementing this functionality. Therefore, autotests can “fall”, and after the completion of the implementation of the functional, it may turn out that this test is not suitable for testing it.
Do not expect magic from test automation
Automated tests do not guarantee that all bugs will be found. They only relieve testers from the routine work of regression testing. As a rule, using manual testing, there is a much larger number of bugs.
Understand the context
- Tests can be automated at any level: Rest or soap services, API, services, GUI. For the level there are their own testing objectives. Unit testing ensures that the code works correctly at the class level, which it compiles and does what is expected of it.
- API tests or integration tests test the interaction of classes with each other.
GUI tests check if the system is working according to some documentation or requirements. At this level, validation is tested more than any other functions.
