It is impossible to automate all testing, so it is important to determine what test cases should be automated first. The benefit of automated testing is linked to how many times a given test can be repeated. Tests that are only performed a few times are better left for manual testing. Good test cases for automation are ones that are run frequently and require large amounts of data to perform the same action.
There are many situations, when you realize that Automation Testing must be done:
1) To Optimize the Speed & Efficiency
2) To Increase the Quality and Decrease the Cost: In software development processes, time-to-market is always on priority. Automation test design for Regression testing, Functionality testing, Re-testing the existing modules, so that auto-scripts run fast and frequently. It’ll surely reduce the time, cost and increase the speed.
3) When there is a repetition or a need to run the test cases a lot number of times in a test cycle.
4) When there are number of test cases under one test-suite: In this case you’ll feel tired after executing each test cases from that test suite, then automation can provide you better results.
5) When there is a requirement of running the test cases in a defined order: While doing software testing, there are scenarios in which you need to test specific feature/module before the others. To achieve this in manual testing its required to remember the order, or you’ll write the order in some other file(.doc, txt, excel) and will refer that. But with automated testing, you can design the scripts in such manner as per our needs.
6) To Increase the Test Coverage: As a human, there are some areas remain left while doing Regression/Retesting. So Automation test helps you to cover all test cases for each module.
7) When you need to run the same test cases on different machines at the same time: When there is a requirement to run the same set of test cases simultaneously on multiple machine, then automation is your answer. Under manual testing process, you cannot execute same test case at the same time on several machines.
8) When you need to test single functionality with multiple data sets: At the time of testing process, you need to run the same test case with multiple data. Then data driven automation testing framework comes in picture to minimize your effort & time. The data is fetch from an external source (e.g. Excel) and pass the multiple and big-size data to each test case. In manual testing, you get bored of testing same functionality and chances of error can increases.
9) When you need to run Regression/Sanity/Smoke Test Suite: Regression test suite consists selected number of test cases, which need to be tested after every defect fix cycle. For regression/sanity testing there is a need of automation testing, because:
10) Generation of Detailed Reports: Mostly all automated testing tools generate test reports automatically once the testing cycle completes. This eases the job of identifying defects and allow the test team to make decision to reliability of the product. So Automation is the solution.

- Repeated execution of test-cases (after each new functionality).
