Make dataset's values of DateTime | Carbon readable in test output

[AndreSchwarzer]

Motivation

I need to test a lot of scenarios which depend on where in time something happens.

While testing and using datasets, I noticed the output of the "current loop" could be improved.

Maybe it is already possible: Please tell me how. Otherwise I'm hoping someone can lead me in the right direction.

I'd like to invest time into extending/changing/overriding the output. I just have no idea where to start to look for something like this. Hints are appreciated.

What I have / get

I tested some date depending validations. The dataset gets "displayed" in the test's output, but not in a readable way.

[
        ['expect' => false, 'activeFrom' => null, 'activeUntil' => null],
        ['expect' => false, 'activeFrom' => null, 'activeUntil' => Carbon::yesterday()],
        ['expect' => false, 'activeFrom' => null, 'activeUntil' => Carbon::today()],
        ['expect' => false, 'activeFrom' => null, 'activeUntil' => Carbon::tomorrow()],

        ['expect' => true,  'activeFrom' => Carbon::yesterday(), 'activeUntil' => null],
        ['expect' => false, 'activeFrom' => Carbon::yesterday(), 'activeUntil' => Carbon::yesterday()],
        ['expect' => true,  'activeFrom' => Carbon::yesterday(), 'activeUntil' => Carbon::today()],

        ['expect' => true,  'activeFrom' => Carbon::today(), 'activeUntil' => null],
        ['expect' => true,  'activeFrom' => Carbon::today(), 'activeUntil' => Carbon::today()],
        ['expect' => true,  'activeFrom' => Carbon::today(), 'activeUntil' => Carbon::tomorrow()],

        ['expect' => false, 'activeFrom' => Carbon::tomorrow(), 'activeUntil' => null],
        ['expect' => false, 'activeFrom' => Carbon::tomorrow(), 'activeUntil' => Carbon::tomorrow()],
        ['expect' => false, 'activeFrom' => Carbon::tomorrow(), 'activeUntil' => Carbon::tomorrow()->addDay()],
]

The output looks like

What I want to get

Something like $carbon->toISOString() would be nice.
