Power-assert graph incomplete

[jyboudreau]

Description

Power assertions with Ava outputs incomplete graphs.

Test Source

test('A test', t =>{
    const arr = ['foo', 'bar'];
    t.true(arr.indexOf('moo') !== -1);
});

Expected assertion output

t.true(arr.indexOf('moo') !== -1)
         |   |              |   |
         |   |              |   -1
         |   -1             false
         ["foo","bar"]

Note: This is the output you get from using power-assert directly in something like mocha.

Actual assertion output

t.true(arr.indexOf('moo') !== -1)
             |
             -1

@jyboudreau @sindresorhus This is expected since AVA uses succinct renderer, not the verbose one used by power-assert by default .

[jyboudreau]

The documentation of Ava definitively alludes that the output of assertions will be like what the verbose renderer outputs.

I would vote for switching the renderer to the verbose one.

[sindresorhus]

@twada I would definitely want to see the array value with the SuccinctRenderer. Just seeing -1 isn't very useful.

@jyboudreau The verbose one is too verbose. We try to strike a balance. In this case, ours was too minimal.

[twada]

@sindresorhus Agreed. Let's getting SuccinctRenderer better.
@jyboudreau Thank you for reporting!

We now print all values through our formatter, so this issue is no longer applicable.
