Test Cases: Do You Really Need Them?
Test cases have a clear structure, allowing you to easily keep track of the testing process. You will always be aware of what has already been tested, what has not been tested yet, which test has passed, and which one has failed.
Sometimes the tester doesn't understand how to test the product because the requirements are not clear. There is also a situation where it is generally impossible to test the solution. The test case will help the testers identify and solve the problem.
Test cases include all the necessary information about the project. These can be passwords, certificates, documents, and other important notes. You will always find the data you need quickly and easily.
If a new tester joins the project, test cases will help you describe the product and its features easily and quickly. What's more, if any tester leaves the project, it won't be very painful to replace him/her thanks to the test cases.
Using test cases significantly speeds up regression testing.
Test cases will allow you to hire less qualified specialists and save money on labor costs.
Using test cases and other materials from a previous project will make it easier for you to work on the following tasks.
