What are some popular mocking libraries for TypeScript?
Some popular mocking libraries for TypeScript include Jest, Sinon, and ts-mockito. Each has its own features and benefits.
Can you explain how to use Jest for mocking?
Sure! In Jest, you can use jest.mock() to mock modules and jest.fn() to create mock functions. This allows you to control the behavior of dependencies in your tests.
What about Sinon? How does it compare to Jest?
Sinon is more focused on spies, stubs, and mocks, while Jest is a complete testing framework with built-in mocking capabilities. It depends on your needs!
Are there any TypeScript-specific features in these libraries?
Yes, both Jest and Sinon have TypeScript typings available, which help with type safety and autocompletion in your tests.
