Libraries are used in automation software testing because they provide a way to share code between different test scripts. This can be very useful when there are common tasks that need to be performed in multiple tests. By using a library, you can avoid having to duplicate code in multiple test scripts.

Libraries can also be used to abstract away complexity. For example, if you are testing an application that has a complex user interface, you can create a library that contains all the code needed to interact with the user interface. This can make your test scripts simpler and easier to understand.

Finally, libraries can be used to improve the reusability of your test code. If you have a library of well-tested code, you can reuse this code in new test scripts, which can save you a lot of time and effort.
