What is a test case management tool, and why should a test team have a test case management tool?

I want to know what is a test case management tool, and why should a test team have a test case management tool. Can anyone please help me out with it.

According to Wikipedia “Test case management tools are used to store information on how testing is to be done, plan testing activities and report the status of quality assurance activities.”

If I say in simple language, Test case management systems(TCMS) are everything about tests in under a single umbrella. You’ll find out what is the test procedure, when was the test performed, who performed it, what was the result, everything in a single management system.

That’s the beauty of a TCMS.

You don’t need to put pressure on your mind reminding when did you perform the test, what test did you perform, what was the result. All you need to do is to just open the tool and find out logs and results.
