Allow verify()

[elliotchance]

Verify is supported by some other testing frameworks. It allows an assertion that does not stop the execution of the test.

• Each verify() counts as an assertion for reporting purposes.
• Failure messages will contain all failed verifies as well as the possible failed assertion. Each of these would contain backtraces.

$this->verify(123, equals, 456);
// Code can still continue, but the whole test will fail if at least one verification fails.

This is most useful when testing many properties of an object where a single failure would not normally break execution:

public function testVerify()
{
    $data = $this->fetchData();

    // if its not an array, we must stop here
    $this->assert($data, is_an_array); 

    // failures here do no break execution and we can see all the failures in the output
    $this->verify($data, has_key, 'total', with_value, 1.23);
    $this->verify($data, has_key, 'lines');

    // $data['lines'] must be an array
    $this->assert($data['lines'], is_an_array);

    $this->verify(count($data['lines']), equals, 3);
}
