What is Automation Testing?
In software development, every software/ website needs to be tested before delivery to customer to make sure it works properly and satisfies what customer needs. Testing can be done by different ways: manual testing or automated testing.
Manual testing is a process of carefully going through application screens, trying various usage and input combinations then comparing the results to the expected behavior and recording the observations. During development cycles, manual tests are repeated often for source code changes and other situations like multiple operating environments and hardware configurations.
Automated testing is a process of automating the manual process to test the application/system. Automation testing involves the use of a separate testing tool which lets you create test scripts which can be executed repeatedly and doesn’t require any manual intervention. Automated testing is the best way to increase the effectiveness, efficiency, and coverage of your software testing.
Why do we need Automated testing?
Once Automated testing is used, it brings us a lot of benefits:
- Saves Time and Money by supporting unattended execution of repeated test cases: testing has to be repeated often during development cycles to ensure quality. Every time source code is modified or having a new release, software tests should be repeated. We may have to test on all supported operating systems and hardware configurations. So, manually repeating these tests is costly and takes a lot of time. If automated test is used, it can be run over and over again at no additional cost and they are much faster than manual tests. Automated testing can reduce the time to run repetitive tests from days to hours and it is significantly helpful in cost saving.
- Enables parallel execution which cannot be done by manual testing: when we want to test how well a website works with thousands of users log in to the system concurrently, manual testing seems hard to perform this task even we have the largest testing team. With Automated testing, we can simulate thousands of virtual users to interact with our website for our test purpose.
- Improves accuracy: It is very easy that testers can make mistakes during perform manual testing. With automated testing, test cases will be executed precisely in every step and detailed results can be recorded clearly.
- Increase Test Coverage: In testing a large test matrix, automated testing can easily execute thousands of different complex test cases during every test run. Furthermore, with automated testing, we can check deeply our application such as see memory contents, data tables, file contents, to determine if the product is behaving as expected.
Automated software testing is the best way to increase the effectiveness, efficiency, and coverage of our software testing.
