Hello,

I have created a TestLogger. I hope that you feel that this fits inside your package. I know that Monolog has a TestHandler but I believe this is better for the following reasons:

• Simpler initialization of Logger inside tests. At the moment in order to perform my tests I need to initialize a Logger and then a TestHandler.. More properties that I have to maintain inside my code... etc etc.
• Faster tests since it does minimal work. It skips all the extra work that it is made by Logger class.
• Inside the TestHandler you have the getRecords function. Even if I retrieve all the records when I need to do simple asserts I can not.. Check this:

$this->assertSame(['level' => 'warning', 'message' => 'that', ['context' => []], $records[0]];

The record contains a lot of extra information that in my case they are not needed.

Even in your tests you had to do unset. So I don't need to have all these information like formatted etc etc.

All I need to test is that the API of the LoggerInterface class is called correctly.
