Let's find something you may need to use and leave with many takeaways.
Why use Mock?
Mock can be understood as creating a fake object or mocking up an object to be used in a test environment to replace the real object
* Verify how certain methods of the object are called, how many times they are called, what the parameters are, etc.
* Define the behavior of the object to specify the return result or to specify a particular action.
In which cases do I need to use a Mock instead of a real object?
* The behavior of real objects is uncertain (ex: current time or temperature)
* Real objects are hard to build
* The behavior of the real object is hard to trigger (ex: network error, network delay)
* Real objects are slow (ex: need to initialize data first)
* Real objects are user interfaces
* Real objects use a callback mechanism
* Real objects may also not exist
* Real objects may also not exist * Real objects may contain information and methods that cannot be used as tests
Ok.let go through these test tools.
