What is fake

Describing the scenario

• Suppose we want to check the memory usage of a function
• The function create 1000 records and we need to check this
• Here we use the fakes

What are the fakes

• Fakes are almost the working implementation
• But it is a shortcut implementation
• Using the fake, we can connect to the local HTTP server

What it does

• Instead of connecting to the remote server, it connects to the local server implementation
• Then it responds to the actual data it receives from the local server.

Difference in using mocks and fakes

• When we use mocks when the production code changes, we need to make a lot of changes in the test code as well
• using the fake version, we are separating what from how, we just need to visit the fake code and change the implementation

Most of the time, when we are using a rest API and we want to load test the API, we end up using the fakes
