“Test automation increases the overall software efficiency and ensures robust software quality.”
Firstly, to get an idea of what Automation Testing is, here are two definitions explaining manual testing and automation testing:
- Manual testing is performed by a human sitting in front of a computer carefully executing the test steps.
- Automation testing means using an automation tool to execute your test case suite.
The goal of Automation testing is to reduce the number of test cases executed manually, but not get rid of manual testing altogether.
Test automation provides faster feedback, accelerated results and more testing efficiency.
Automated tests can be run virtually unattended, leaving the results to be monitored towards the end of the process. You can run automated tests overnight!
Test Automation helps to detect defects earlier. The earlier a defect is detected, the more cost-effective it will be to fix.
Manual testing can sometimes be seen as tedious, especially when test cases are repetitive and time consuming. Automation allows testers to focus on more challenging and rewarding work such as risk analysis and exploratory testing.
Humans are not perfect and testers can make mistakes during manual testing. Automated tests perform the same steps and always records detailed result, this helps to improve accuracy.
With test automation, many more tests can be executed which will lead to increased test coverage.
Test Automation has many benefits (as seen above) and can also be very useful when using agile methodologies. “To fulfil the needs for fast deployment, testing methods need to be faster.”
