Delete paraphrased info from value labels which the description line can communicate by formatting.

  1. Contrast: Format not as regular instead of dim when assertion fails.

  2. Contrast: Instead of [.not] when arg validation throws an error, either format or omit not using new isNot option of matcherHint according to isNot property of matcher. Residue: ensureNoExpected and so on exported by jest-matcher-utils will wait until later because need another argument.

  3. Contrast EDITED 2018-02-20 per Improve description line when assertion fails: part 2 #5512 (comment) format matcher name as regular instead of dim. For backward compatibility, format preceding period as dim, even if matcher name includes it.

  4. Contrast: EDITED 2018-02-20 also format rejects or resolves as regular instead of dim via new prefix option of matcherHint function.

  5. Alignment: Because Expected: and Received: have same length without paraphrased info, display values starting on same line instead of indented on following line.

The “developer experience” goal is know where to look for what purpose:

  • Look at description line to understand the assertion.
  • Look at values or diff to decide whether the change is progress or regression.

Next PR will continue in alphabetical order at toContain

Here are some samples [of original improved design with matcher name as dim]:

xxxx_not_tobedefined

xxxx_tobedefined

xxxx_tobecloseto_precision

xxxx_tobeinstanceof

EDITED on 2018-02-20 samples of more improved design with matcher name as regular:

5512a_tocontain

5512a_tocontainequal

5512a_tohavebeencalledtimes

5512a_not_tohavebeencalledtimes

5512a_tohavelength

5512a_tomatch

5512a_tomatchsnapshot_unnamed

5512a_tomatchsnapshot_named

Test plan

EDIT: Updated snapshots for integration-tests:

  • 3 for failures
  • 1 for jasmine-async
  • 2 for to_match_snapshot

Updated 179 snapshots for toBe… matchers:

  • 18 for toBe
  • 12 for toBeCloseTo
  • 10 for toBeDefined
  • 16 for toBeFalsy
  • 14 for toBeGreaterThan
  • 19 for toBeGreaterThanOrEqual
  • 9 for toBeInstanceOf
  • 14 for toBeLessThan
  • 19 for toBeLessThanOrEqual
  • 14 for toBeNaN
  • 10 for toBeNull
  • 16 for toBeTruthy
  • 10 for toBeUndefined

EDITED on 2018-02-20 Updated more snapshots for other matchers:

  • 24 for toContain and toContainEqual notice comments: strict equality versus deep equality
  • 65 for toEqual notice comment deep equality
  • 13 for toHaveLength
  • 40 for toHaveProperty
  • 17 for toMatch
  • 53 for toMatchObject
  • 11 for toThrow
  • 11 for toThrowError
  • 9 for rejects
  • 17 for resolves

55 in spy_matchers

  • 4 for toBeCalled
  • 1 for toBeCalledWith
  • 4 for toHaveBeenCalled
  • 10 for toHaveBeenCalledTimes
  • 12 for toHaveBeenCalledWith
  • 12 for toHaveBeenLastCalledWith
  • 12 for lastCalledWith

A few of the snapshots descriptions were a puzzle to me but the changes were consistent.

This is pretty controversial change :D but I kinda like the consistency of the output (at least when it's short).

Wouldn't it be better for readability, if we change the matcher name (e.g. .toBeDefined()) to have some more visible, neutral color, e.g. blue or even default non-dimmed color? I think it would be easier to read this way.

Shouldn't this matcher be collapsed too?

Do you mean display all three lines for not version of assertion?

If yes, then I agree and will change it to simplify code and make report more consistent.

I wonder why this matcher has asymmetric toBe/not.toBe output – I don't see any reason we shouldn't suggest toEqual for not.toBe assertions, same with showing a diff.
It's not related to this PR, but why not fix it right away.

Let’s please wait for a future PR, because it’s a double negative when .not.toBe fails.

I like it because it increases information density and uses less vertical space. It does look slightly less consistent overall but I think it works well for the matchers you are changing. I'm in favor.

@thymikee Here are three pictures of alternatives based on your suggestions. What do you think?

Display matcher name in regular weight instead of dim.

5512a_not_tobedefined

Display precision argument value in description line.
