Automation testing is the application of tools and technology to testing software with the goal of reducing testing efforts, delivering capability faster and more affordably. It helps in building better quality software with less effort. Automation Testing is one of the best methods to ensure that the newer app version does not hinder the existing functionality of the app or create a new bug. Automation Testing ensures that you can market your product in a lesser time with less risk of human error.

1) It reduces human error when operating the same operations each time.

2) Automating the testing is significantly more durable than manual testing, as it does not consume more time like manual testing.

3) We can reuse the same test scripts for different versions of the application if needed.

4) Gives immediate feedback to developer’s detection defects early in turn saving cost.

Benefits of Automation Testing

1) Automated Testing Saves Time and Money

Software tests must be repeated often during development cycles to ensure quality. Every time source code is modified software tests should be repeated. For each release of the software it may be tested on all supported operating systems and hardware configurations. Manually repeating these tests is costly and time consuming. Once created, automated tests can be run over and over again at no additional cost and they are much faster than manual tests. Automated software testing can reduce the time to run repetitive tests from days to hours. A time savings that translates directly into cost savings.

2)  Reduced Regression Testing Cost

Automated testing is more cost-effective than manual. Manual testing doesn’t allow you to run repetitive tests. In fact, the cost of testing your application manually rises as time goes. By contrast, automated testing is cheaper in the long-term perspective, because once you’ve created your test scripts, you can reuse them 24/7 without any additional cost. True, the initial adoption of automaton may be somewhat expensive, but it will pay off quickly.

3) Higher Test Coverage

 Manual testing puts limits on how many tests you can verify. Automation allows you to spend time  writing new tests and adding them to your automated test suite. This increases the test coverage   for your product, so more features are properly tested resulting in a higher quality application.

 Also, automated testing allows developers to write more in-depth tests that test complex use cases. Lengthy tests that are often avoided during manual testing can be run unattended.

4) Better Insights

Automated testing provides better insights than manual testing when some tests fail. Automated software testing not only gives insights into the application but also shows you the memory contents, data tables, file contents, and other internal program states. This helps developers determine what’s gone wrong.

5) Automated Testing Provides More Features

Test automation helps you to automate tests to determine the stability of your build. Often,  smoke testing is used to validate stability. However, smoke testing is slow and requires manual  input from the testing engineer such as setting up databases with test data.

6) Eliminate Human Error

Manual testing opens the opportunity for humans to make mistakes. Especially for complex   scenarios, it makes sense to use test automation to avoid mistakes. You can still make mistakes,   even with test automation. However, the rate of mistakes is significantly lower when using test automation for your test suite.

7) Improves Accuracy

 Even the most conscientious tester will make mistakes during monotonous manual testing. Automated tests perform the same steps precisely every time they are executed and never forget  to record detailed results. Testers freed from repetitive manual tests have more time to create new automated software tests and deal with complex features.
