Test Utilities Manager
A utility module that provides test helper functions for managing and cleaning up mock states in test suites. The module should help developers properly reset test mocks between test cases to prevent test pollution.
Capabilities
Mock State Cleanup
- Clears all call history from a provided mock function without removing its implementation @test
- Completely resets a mock function by clearing its history and removing any custom implementation @test
- Restores a spy to its original implementation while keeping the spy functional @test
Batch Mock Management
- Clears call history from multiple mock functions at once @test
- Resets multiple mock functions at once, removing all implementations @test
