Manual Testing vs Automated Testing

Manual testing involves human intervention to test a software application, where testers manually execute test cases without using any automation tools.

On the other hand, automated testing involves the use of automation tools to execute pre-scripted tests on a software application. These tests are designed to validate functionality, performance, and other aspects.

Key Differences:

1. Efficiency: Automated testing is faster and more efficient compared to manual testing, especially for repetitive tasks.
2. Reusability: Test scripts in automated testing can be reused multiple times, saving time and effort in the long run.
3. Precision: Automated tests are more precise and reliable as they eliminate human errors that are common in manual testing.
4. Scalability: Automated testing can easily scale up to test a large number of test cases, whereas manual testing may become cumbersome for extensive testing.
5. Cost: While automated testing tools may have an initial cost, they can ultimately save costs in the long term by increasing productivity and reducing manual testing efforts.

In conclusion, both manual testing and automated testing have their own advantages and disadvantages. The choice between the two depends on factors such as project requirements, budget, timeline, and the expertise of the testing team.
