ts-mockito is a strongly typed mocking library for TypeScript inspired by Mockito. It provides mock creation, spying, stubbing, verification, and argument capture for use in unit tests.

Use cases

• create type-safe mocks of TypeScript classes
• stub method calls to return, throw, or resolve promises
• verify methods were called with specific arguments
• spy on real objects and override their behavior
• capture arguments passed to mocked methods
• verify call counts and call order in unit tests

When to choose

• you write unit tests in TypeScript and want strongly typed mocks with IDE autocomplete
• you know Mockito from Java and want a familiar API in TypeScript
• you need spies, stubs, verification, and argument capture without extra setup

When to avoid

• you need actively developed tooling - releases are infrequent
• your project uses JavaScript only without TypeScript
• you prefer an all-in-one test framework with built-in mocking like jest or vitest
