Flexible parameters

[phzbox]

Is there a matcher to return a value from literally any kind of parameters, such as:

  let f = td.func()
  td.when(f(???)).thenReturn('abc')

  f() // abc
  f('a') // abc
  f(1,2,3) // abc

The only way I found was to do:

  let f = td.func()
  let anything = td.matchers.anything

  td.when(f()).thenReturn('abc')
  td.when(f(anything())).thenReturn('abc')
  td.when(f(anything(), anything(), anything())).thenReturn('abc')

You're looking for the ignoreExtraArgs Option.

td.when(f(), {ignoreExtraArgs: true}).thenReturen(5)

It's documented in the chapter on when stubbing
