Differences between Test Plan, Test Strategy and Test Case

In software development there are many terms that they seem similar but in fact there are the differences. The words "Plan-Strategy and Case" related with Test are a good example for this. Even though they have different functions , they are all connected to each other. But what are they?

>Test Plan : It' s a super document that lists EVERYTHING that will be required in the project. It's a detailed road map with all activities like the scope, the roles, entry-exit criteria and test objectives.

>Test Strategy: We find the details in strategy. It gives us clear details to decide what kind of tools we need to use for different types of tests.

>Test Case: It's more specific. The steps that will be performed in the test are written here. It also includes the conditions, environment, expected-actual results and the situation whether the tests passed or failed

I hope with the knowledge of these differences between these terms we can create better plans ;)
