Pros Vs Cons of Manual Testing

Manual Testing
Manual testing is a software testing method where testers execute test cases and verify the software functionality, usability, and other features manually, without using any automation tools or scripts. In manual testing, human testers play a vital role in identifying defects, verifying whether the software meets the specified requirements, and ensuring that it functions as expected.

Benefits of Manual Testing

• Manual testing allows testers to interact with the software just like end-users would which gives insights to the actual user experience and identifying usability issues which are all unnoticed during automated testing.
• Human testers have the ability to explore the software in an ad hoc manner, and identifying the unexpected issues and scenarios that are all not covered by predefined test cases.
• Manual Testing is highly effective on Non Functional testing in a way of user experience and interface which are all not easy in automated testing.
• Manual testing is well-suited for complex scenarios testing which involves multiple variables or interactions that are difficult to automated testing
• Manual Testers provide early feedback on software usability, feel, look and other aspects of non functionality of application which are not easy in automation.

Drawbacks of Manual Testing

• Manual testing is highly time-consuming and requires large amount of human resources to execute test cases, efficiency of manual testing on large scale or repetitive task is very low.
• Human errors occurs during the execution of test cases, potentially leading to inaccurate results or missed defects.
• Investment of time & money is so high on Manual Testing like hiring the skilled professional requires more time & cost during the product making
• Regression testing, which involves repeatedly executing the same test cases which become monotonous and error-prone for testers.
• The manual documentation of test cases, results, and defects are time-consuming process

Examples for Manual Testing:

• Ad Hoc Testing: Testers perform unplanned testing to identify defects or issues in specific areas of the application or software in a quickly manner.
• User Acceptance Testing (UAT): client representatives manually test the software to validate whether it meets their requirements and expectations which are all conducted in three levels (Alpha,Beta,Gamma)
• Security Testing: Testers manually finds the security flaws and identify vulnerabilities in the software, such as data leakage risks or weak authentication mechanisms.
