Need for Automation Testing

1. Testing manually for all the possible scenarios again and again for regression is time taking and also it won't give you result with the same efficiency as automated script will do as humans tend to commit mistake when executing the same tests again and again or efficiency won't be same each time.

2. Manual Testing is a monotonous job so it is very exhaustive and tiring process compared to automation.

3. Fewer Human Resources or does not require Human intervention .

4. Automation expands the speed of test execution.

5. Re-usability- Automation test scripts can be re-used with some modifications.

6. Reliability-Testing with Automation tool Improves Accuracy.

7. Accelerates cross-browser and cross-device testing.

8. Running Tests 24/7- No matter where you are in the world. You can start the tests when you leave the office and when you get back in the morning you can see the results and keep on working.
