Added a test logger

[gmponos]

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.

Could you move this inside a Monolog\Test\ namespace (but still in src/)? If you also wanna help out by taking care of #1197 at the same time that'd be even better :)

On the other hand, I kinda wonder if this doesn't belong more in the psr/log package as it doesn't have anything monolog specific really

I had the same dilemma... if I should commit it here or on the PSR. Checking PSR now again I just saw this namespace Psr\Log\Test so yes I believe it could fit in there. check the PR php-fig/log#57

Thank you.

Ok gonna close this here then.

Hi @Seldaek do you think that this could be added in here now that the TestLogger is removed from psr/log ?

@gmponos as there is still nothing specific to Monolog in that TestLogger (the monolog-specific way is to use the TestHandler of Monolog), you can maintain that in its own package.
