[3.0.0] - 2020-11-01

Fixed

• spy.getAllCallArguments was returning a wrong value.

Removed

• flow support
• node support for versions lower than 12

Added

• Better TS support and improved auto-import for package users.

Changed

• new Spy() -> Spy() (Spy is no longer a class)

[2.10.0] - 2019-11-06

Added

• spy.getAllCallArguments: Provides a little more flexibility when observing call arguments.

[2.9.1] - 2019-11-04

Fixed

• Fixed node module resolution for Spy.mockModule

[2.9.0] - 2019-11-03

Added

• Spy.MAPPER: A nice shortcut variant of Spy.COMPARE to test the output of given function depending on some defined input. See here for more details.

[2.8.0] - 2019-11-03

Added

• Spy.mockModule: Allows you to mock functions on module level. Can replace the usage of jest.mock in most situations. One example:

  // some module with name "my-module.js"
  export const useMe = (some: string) => 'foo' + some;
  
  // testing somewhere else
  const Mock$MyModule = Spy.mockModule('../my-stuff/my-module', 'useMe');
  
  Mock$MyModule.useMe.returns(42);
  
  expect(useMe('test')).toBe(42);
  
  Mock$MyModule.useMe.hasCallHistory('test');
  

[2.7.0] - 2019-11-03

Changed

• More detailed error messages.

  • Before: --> foo / different string
  • Now: --> foo / different string ['bar' != 'test']

• Improved UX for Spy.COMPARE. You can make assertions that throw instead of returning a boolean indicator. E.g.

  spy.wasCalledWith(Spy.COMPARE(fn => {
      expect(fn()).toEqual({ foo: 'bar' });
  }));
  

[2.6.1] - 2019-08-26

Changed

• Allow to spy on all kind of bound methods (e.g. window.console.error which is no instance of Function on JSDom)
