描述

Version

29.5.0

Steps to reproduce

  1. Clone my repo at https://github.com/dominiktopp/jestCreateMockFromModuleIssue
  2. npm install
  3. npm test
  4. tests will fail

Expected behavior

I expect the test cases to succeed.

Actual behavior

Tests are failing because jest.createMockFromModule only mocks constructor and functions for classes but no other properties (also no getters). The example for jest.createMockFromModule does not mock an exported class but an instance of a class: class: new (class Bar {...})()

Additional context

No response
