When assertion count is incorrect, output the expected and actual values.

[dylang]

I see that the actual count is recorded, but I'm not sure how to see it when running ava.

https://github.com/sindresorhus/ava/blob/master/lib/test.js#L150-L158

❯ npm test

> npm-check@4.1.2 test /Users/dgreene/projects/npm-check
> xo && ava ./test


  ✖ require Assertion count does not match planned

  1 test failed

  1. require
  Error
    at Test.plan (/Users/dgreene/projects/npm-check/node_modules/ava/lib/test.js:87:19)
    at Test.<anonymous> (/Users/dgreene/projects/npm-check/test/test.js:10:7)
    at step (/Users/dgreene/projects/npm-check/test/test.js:5:273)
    at Test.fn (/Users/dgreene/projects/npm-check/test/test.js:5:99)

The above is using using master with power-assert added.

Similar output using the published version

> npm-check@4.1.2 test /Users/dgreene/projects/npm-check
> xo && ava ./test


  ✖ require Assertion count does not match planned

Confirmed.

It seems simple to change the message in https://github.com/sindresorhus/ava/blob/04b3db5d96d6530d6b03c5f8f4c915dea16cd125/lib/test.js#L155, or would you prefer to use the stored actual and expected properties in the rederer?

[sindresorhus]

The actual stored props should be used, but unsure why they're not. Maybe because we overwrite the stack in https://github.com/sindresorhus/ava/blob/04b3db5d96d6530d6b03c5f8f4c915dea16cd125/lib/test.js#L159.

Ok, @sindresorhus: Here's the problem. Actual/expected are only included when no message is provided, see here and here. So we have to include that in the error message ourself. I'll submit a PR.

Fixed in #376.

+1, would like to see this fixed!
