Difference between Manual and Automation testing

Manual Testing:

1. Human Execution: Manual testing involves the direct involvement of human testers who execute test cases manually without the use of automation tools.

2. Exploratory: Testers explore the software application, identifying bugs, and evaluating user experience through manual interactions.

3. Flexibility: Manual testing allows testers to adapt quickly to changes in requirements or user interface designs.

4. Initial Investment: Typically, manual testing requires lower initial investment as it doesn't involve purchasing automation tools or setting up automated test environments.

5. Skill-Dependent: Manual testing relies heavily on tester expertise, domain knowledge, and attention to detail to identify defects effectively.

Automation Testing:

1. Tool-based Execution: Automation testing involves the use of specialized tools and software scripts to execute test cases automatically.

2. Repetitive Tasks: Automation is suitable for repetitive tasks such as regression testing, where the same test cases need to be executed multiple times.

3. Speed and Efficiency: Automation testing can be faster and more efficient for executing large test suites or performing complex test scenarios.

4. Cost and Time Savings: While automation may require upfront investment in tools and infrastructure, it can lead to long-term cost savings and faster time-to-market by reducing manual effort.

5. Limited Human Intervention: Automation testing reduces the need for human intervention once test scripts are developed and maintained, freeing up testers to focus on more strategic or exploratory tasks.
