In testing, a mock is a simulated object that mimics the behavior of a real object - we use mock in cases where we need to test something that requires a feature that is not yet available, so we simulate it.
Mocks are used to isolate the code under test from its dependencies, such as databases, APIs, or other classes.
By using mocks, you can control the inputs to the code being tested and verify how it interacts with its dependencies. This makes tests more reliable and easier to write.
For example, if you're testing a function that interacts with a database, you could use a mock database object to simulate the database's behavior without actually connecting to a real database.
