add inverse expect asymmetric matchers #5517

quantizor · 2018-02-10T23:18:49Z

Summary

Closes #5510

Add inverse asymmetric matchers for arrayContaining, objectContaining, stringContaining, and stringMatching.

Test plan

Added unit tests.

~~Should I add inverse matchers for .any and .anything?~~

So we don't want to have expect.not.objectContaining?

Yeah, I prefer to do expect.not.objectContaining as well since that is now expect works normally. I think it would create API inconsistency if we didn't do this.

We could just pass the "not" argument in constructor and reuse existing classes, instead of creating new ones extending the old.

Can you revert this? I do not want us to rely on class names in JavaScript. We may want to minify or mangle these at some point and this would break. Any user visible value should come from strings, not from data structure reflection.

Is it okay if I review this PR on Wednesday February 14 to compare its direction with recent PR #5503 and discussion about future of AsymmetricMatcher class for user-defined matchers in #4711

@pedrottimark is there anything I can do to help?

quantizor · 2018-03-04T09:17:54Z

Okay, I think this should be reworked to your comments

  asymmetricMatch(other: Object) {
    if (typeof this.sample !== 'object') {
      throw new Error(
-        "You must provide an object to ObjectContaining, not '" +
+        `You must provide an object to ${this.toString()}, not '` +


do we want the toString?

Yes, so the error message is more intelligible. I think at least.

@probablyup mind running prettier over the documentation to please CI (yarn lint:md)?

Also, please update the changelog.

@SimenB done, thanks for your time in reviewing!

I like it, this is pretty awesome! 😀

Nice, this is cool! Can you add this to the documentation? :)

quantizor · 2018-03-04T21:59:55Z

@cpojer I added to the expect API markdown files, is there something else I need to edit?

cpojer · 2018-03-04T22:05:14Z

Yeah, I was wondering if we could add some usage examples possibly?
