Test Automation- The holy grail of testing

While developing a software, testing is an important part. Testing is often done manually which involves a person who sits in front of a computer to execute test steps carefully. A better alternative to this is automation testing which involves using automation tools for execution of testing. Some software enters test data into System Under Test and compares the actual as well as expected results and then detailed test reports are generated. Resources and money have to be invested in Test Automation but it is all worth it due to the benefits that is reaped from this.

Test automation is generally used in software during any or all of the following scenarios:

  • Critical and large projects
  • Projects requiring frequent testing out of same areas
  • If the requirements do not change too frequently
  • Time is available
  • The software is stable during manual testing
  • The application has to be accessed for performance as well as load with several virtual users.

During the cycles of development, software tests are often repeated so that quality can be ensured. With the modification of source codes, software tests have to be repeated on all hardware configurations and operating systems supporting it. It is time consuming as well as costly to repeat the tests manually. The advantage of automated testing is that once they are created numerous tests can be run as many times as you want without any additional costs. On top of that, compared to manual test they are quite faster as they reduce the running time to just hours from days.


Accuracy is greatly improved with this testing. In case of manual testing, even if the tester is very conscientious and precise, he is bound to make some mistake or the other when carrying out the process as it can be monotonous and cumbersome. The same steps are performed by automated tests every time and detailed results are also recorded. The area of coverage can be increased by using this type of testing. The scope and depth of tests are increased and in fact you do not have to avoid lengthy tests which can be run on multiple computers despite having different configurations.

Web application tests for hundreds of users is quite an impossible task even if the software departments are large; this scenario however, is not applicable for automated testing which simulate thousands at one go. When you adapt this method you have to form a test suite which after due course of time becomes out of date due to the change of working of existing features or introduction of some new functionality. When the out of date tests are run they will automatically fail which makes it necessary to fix test scripts which ensures that the scripts are always modern and up to date with special attention given to the maintenance of software quality.

Despite the change of interface, the software's different versions can reuse the tests, which makes it quite cost effective. A very important reason for adopting this testing method is that it is extremely reliable in results which ensures consistency as well as efficiency. A lot of time is saved from the point of view of both developer as well as tester which can be utilized for concentrating on other projects which may be more rewarding as well as challenging.

Although products of software development groups are always tested, there are always some defect or the other in the delivered software. Before the release of the product test engineers work hard to detect them but they always manage to linger and reappear. This factor is eliminated by test automation. However, the role of testers cannot be eliminated completely as not every feature can be tested like that; in some cases this testing is not suitable for all projects.
