Unexpected output with td.matchers.isA(Function)

[codedbypaul]

When I use:

td.verify(mockAdapter.registerInteractionHandler(td.matches.isA(Function)));

The output is:

Wanted:
  - called with `(isA(Function))`.

All calls of the test double, in order were:
  - called with `("change", function (evt) {
    return _this.handleChange_(evt);
  })`
fail
default

Am I misunderstanding how isA(Function) works?

The functions being used:

this.adapter_.registerInputInteractionHandler('change', this.groupChangeHandler_);
this.groupChangeHandler = (evt) => this.handleChange_(evt);

Based on called with ("change", function (evt) { from the error message, it looks like the assertion is correct to fail, since the first argument is a string and not a function. Shouldn't the test be:

td.verify(mockAdapter.registerInteractionHandler("change", td.matchers.isA(Function)));

(Will reopen if I have that wrong)

Ah yes that passes. Thanks for that.
