Add support for PHPUnit's @depends

[nuernbergerA]

This PR adds support for Test Dependencies.

Usage

test('first', function () {
    assertTrue(true);

    return 'first';
});

test('second', function () {
    assertTrue(true);

    return 'second';
});

test('depends', function () {
    assertEquals(
        ['first', 'second'],
        func_get_args()
    );
})->depends('first', 'second');

Feel free to change this PR or request changes.

Cheers Adrian

Going to review this, meanwhile can you also update the docs on this. @alexmartinfr will review the grammar.

[nunomaduro]

Great job. Let's adjust some small details before merge.

[nunomaduro]

Let me know when you think this is ready.

[nunomaduro]

Merging this during the weekend. Good job! Can you also work on the docs?

[nuernbergerA]

Summon @mathiasonea to write docs

[alexmartinfr]

I'll be free to review the draft tomorrow afternoon and Sunday if needed 👌

(If you can't, you can provide a stub with the structure / main informations and I can work on that).

[ariaieboy]

@ariaieboy you are more than welcome to contribute this part to the docs 👍🏼

[ariaieboy]

i dont know where should this one go in the document should we add this to writing test section ?

[owenvoke]

It can probably have it's own section, similar to the groups() functionality. 👍🏻 We can always change the location if it doesn't seem right.
