What are most common mistakes done as a tester?

Avoiding Inadequate Test Planning is crucial in software testing. Comprehensive planning ensures that all aspects of the software are thoroughly examined, minimizing the risk of undetected issues. Without a solid plan, testers may overlook critical areas, leading to incomplete or ineffective testing.

Not testing enough is a common mistake that can have severe consequences. Testing should be comprehensive and cover all aspects of the software, including edge cases and unexpected scenarios. Failing to test thoroughly can result in undetected bugs and issues that may impact users negatively.

Focusing solely on the quantity of test cases rather than their quality can be a significant mistake. Each test case should be designed with the intention of uncovering potential defects and ensuring the software's functionality. Ignoring the quality of test case design can lead to wasted time and resources, as ineffective tests may not reveal critical issues.

Insufficient or no documentation is another mistake to avoid. Proper documentation is crucial for ensuring that all team members understand the testing process, test cases, and results. Without proper documentation, it can be difficult to track progress, identify issues, and ensure that the software meets quality standards.

Overreliance on manual testing is another mistake to avoid. While manual testing has its place, automating tests can greatly improve efficiency and consistency. By automating routine checks, testers can focus on more complex, manual tasks and ensure a higher level of accuracy and speed.
