Quality is king in the world today. Also known as test automation, QA automation helps streamline a number of laborious processes that could have an adverse impact of product quality. This is imperative because the basic parameter that users have for judgments about the performance of a software is the quality of the code behind it.
Test automation is the process of using a set of tools to run tests on software, in order to keep an eye on its progress. Testing helps developers find any bugs and errors in the source code before the software is launched in the open market. It is important to test a product continuously because this ensures deliveries in short cycles and constant testing.
The benefits of test automation
There are several types of testing that can be optimized but the ultimate goal of each is to speed up the process of effective software development. Other benefits of test automation include:
– It saves time on certain processes like regression testing for low level interfaces which are tiresome to perform manually and can increase costs because there is a greater chance of errors.
– Automated testing can also increase the amountnumber of in-depth tests run on a software. These are usually avoided during manual testing because of the complexity involved in the process. However with automation they can be run unattended.
– Accuracy of the tests improves because testing softwares can pick out bugs and errors precisely as well as repeatedly.
QA automation best practices
While testing automation has its benefits, what matters more is the effective execution of the process. To run an automated testing process efficiently, there are a few things that helps increase the productivity.
a. Test consistently: A bug or error can arise at any given moment and it is one of the biggest party spoilers. With automated testing you have the ability to run codes through different tests at regular intervals to make sure that before moving on to the next phase, any imperfections have been hammered out. Automated unit testing can be implemented as soon as the project begins and gradually the number of tests can be expanded depending on the requirements of the software.
b. Know which tests to automate: There are a wide variety of tests like unit testing, regression testing, functional testing, keyword testing etc. It is not possible to automate each and every test so again based on the nature of the project you have to pick certain appropriate ones. The number can increase gradually as the project grows, but it is important to know the most important tests that you need to automate in order to increase productivity.
c. Make sure your tests are not affected by modifications to the UI: The user interface is one of the components that change the most during development. Tests created with scripts or keywords are dependent on the application being tested. This means that as an interface changes, the test results will too. This can hinder the development process considerably.
Automated testing is the answer to many bottlenecks in software development like avoiding costly and extensive tests. However, the secret lies in implementing them effectively.
