`v3.5.0`: Default Behavior Methods

Compare Source

New methods:

defaultReturnValue
defaultResolvedValue
defaultRejectedValue
defaultImplementation

Use them to set up a default behavior, which will serve as fallback if no matcher fits.

when(fn)
  .calledWith('foo').mockReturnValue('special')
  .defaultReturnValue('default') // This line can be placed anywhere, doesn't have to be at the end

expect(fn('foo')).toEqual('special')
expect(fn('bar')).toEqual('default')

Previously you needed to use any of mockReturnValue, mockResolvedValue, mockRejectedValue, or mockImplementation directly on the object before using calledWith to create a default fallback.

// Same as above example
when(fn)
  .mockReturnValue('default')
  .calledWith('foo').mockReturnValue('special')

One neat idea, and the reason I even did this work, is to set up a default implementation that throws an error if an improper call is made to the mock.

when(fn)
  .calledWith(correctArgs)
  .mockReturnValue(expectedValue)
  .defaultImplementation(unsupportedCallError)

// A default implementation that fails your test
function unsupportedCallError(...args) {
  throw new Error(`Wrong args: ${JSON.stringify(args, null, 2)}`);
}

Add several methods to set up default behaviors. These methods can be placed anywhere in the mocking set up, including after other calledWith setups, unlike previous "default" behavior using when(fn).mockReturnValue(z). You can now do: when(fn).calledWith(x).mockReturnValue(y).defaultReturnValue(z). 77fe672
Add documentation example for unsupported call error as default implementation a6dc74d
