[jest-mock] Track thrown errors in MockFunctionState #5764

UselessPickles · 2018-03-09T03:53:24Z

Summary

Allows unit tests to easily access references to errors that were thrown by all calls to a mock function.

MockFunctionState has a new thrownErrors property that is an array containing an entry for each call to the mock. If a call to the mock threw an error, a reference to the thrown error is stored in the array. Otherwise, undefined is stored in the array.

Also fixes: #5761

Test plan

Added a new unit test. Ran yarn run jest jest_mock to confirm that new and existing mock unit tests are passing.

Also fix bug where returnValues array was not updated when an error is thrown.

Everything in the try {} block was simply indented with no other changes. The diff makes it look much worse than it is :)

Append a ?w=1 to the diff URL and font bother :)

Thanks for the tip. Would be nicer if this option was exposed in the UI.

@@ -49,6 +49,24 @@ that looks like this:
 ['result1', 'result2'];
 ```

+NOTE: For any call to the mock that throws an error, a value of `undefined` will
+be stored in `mock.returnValues`.


Could consider including this in the example rather than a note:

For example: A mock function f that has been called three times, returning
result1, then returning result2, and then throwing an error would have a mock.returnValues array
that looks like this: that looks like this:

['result1', 'result2', undefined];

I updated the documentation.
