What is the difference between test automation and manual testing?

Test automation and manual testing are two different approaches to testing software applications. Here are the key differences between the two:

1. Test Automation:

Test automation involves using specialized tools and scripts to automate the execution of test cases. This approach is beneficial for repetitive test cases and regression testing. Some advantages of test automation include:

• Efficiency: Automated tests can be run faster and more frequently compared to manual testing.
• Accuracy: Automation reduces the chances of human errors in executing test cases.
• Reusability: Automated test scripts can be reused across different test cycles.

2. Manual Testing:

In manual testing, testers manually execute test cases without the use of automation tools. This approach involves human intervention in every step of the testing process. Some key aspects of manual testing include:

• Exploratory in nature: Manual testing allows testers to explore the application and identify defects that may not be covered by automated tests.
• Flexibility: Manual testing is more flexible and adaptable to changes in the application requirements.
• Human judgment: Manual testing relies on the tester's judgment and experience to detect usability issues and other non-functional aspects of the application.

Conclusion:

Both test automation and manual testing have their own strengths and weaknesses. It is essential for QA teams to strike a balance between the two approaches based on the project requirements, timelines, and resources available.
