What is Automation Testing?

What is Automation Testing?

Test Automation is the use of software tools to execute and run tests on software apps or systems, rather than manually testing them. Test automation testing allows QA experts the time to focus on varied quality activities such as running exploratory tests, examining test results, etc., by taking over the monotonous and recurring jobs such as Regression testing.

Accordingly, automation testing allows you to achieve great test coverage in the shortest period. Automated testing comprises the use of test scripts and software tools to automate the test process, controlling the time and effort needed for testing. The ultimate objective of test automation is to enhance the accuracy and efficiency of testing by automating time-consuming and repetitive tasks, such as running functional tests, regression tests, performance tests, & load tests.

Automation testing is the best way to enhance the test coverage, execution, effectiveness, and speed in QA testing. Automated software testing is significant due to the following reasons:

  • Manual Testing is problematic to test manually for multilingual sites.
  • Manual Testing of all fields, every workflow, and all negative scenarios is money and time-consuming.
  • Automation Testing enhances the speed of test execution
  • Automated Test in software testing doesn’t require Human intervention. You can execute automated tests unattended (overnight)
  • Automation helps enhance Test Coverage
  • Manual Testing can become tiresome and hence bug-prone.


Difference between Manual and Automation Testing


Criteria Manual Testing Automation Testing
Definition This is a type of testing where the tests are implemented manually by the testing team. It is a type of testing wherein the tests are implemented using automated tools.
Process Manual testing includes a QA engineer manually executing test cases, without the usage of any automated tools. Automated testing includes the usage of automated tools to run test cases.
Speed Manual testing is steadier than automated testing, as it necessitates a human to run the test cases. Automated testing is quicker than manual testing, as it can run test cases much more rapidly.
Repeatability This form of testing is less repeatable and can be prone to human error than automation testing. Automated testing is highly repeatable than manual tests as similar tests can be run the same way each time.
Skillset required Manual testing necessitates a QA tester to have great analytical, communication, and problem-solving expertise. Automated testing necessitates a tester to have better scripting &programming skills, plus knowledge of tools.
Coverage Manual testing can cover a restricted set of test cases. Automation testing can cover a huge no. of test cases and can test monotonous tasks efficiently.
Cost Manual testing is comparatively cheaper, as it doesn’t necessitate any specialized technology or tools. Automated testing is highly costly, as it necessitates specialized tools and technology.
Suitable for Manual testing is appropriate for user acceptance testing, ad-hoc testing, and exploratory testing. Automation testing is appropriate for regression testing, load testing, and performance testing.
Human intervention Manual testing needs human intervention, which can result in inconsistencies and errors in the testing process. Automation testing can execute without human intervention, which eradicates the probability of human error.
Scalability It isn’t scalable, as it is restricted by the number of testers accessible. It is highly scalable, as it can run a huge number of test cases in the shortest period.


The above differences clearly indicate the efficiency of automated testing. But, with manual testing, you advantage of human knowledge and expertise, which an automation testing tool can never offer a match for.
