expectedException is deprecated in phpunit 8

[DQNEO]

It's deprecated in PHPUnit8, and will be removed in PHPUnit9
sebastianbergmann/phpunit#3332

@ExpectedException causes a warning as follows.

The @ExpectedException, @expectedExceptionCode, @expectedExceptionMessage, and @expectedExceptionMessageRegExp annotations are deprecated. They will be removed in PHPUnit 9. Refactor your test to use expectException(), expectExceptionCode(), expectExceptionMessage(), or expectExceptionMessageRegExp() instead.

This is not mergeable as-is. This package lacks any kind of CI nor it requires PHPUnit as a dependency, so we cannot say which version we can use; in particular, this package is usable back to PHP 5.3, so that's a big problem...

Thanks for the comment.
Actually I wanted to raise an issue instead of making a PR, but issues are disabled in this repo so I made this PR to make a discussion.

As you say, there is no declaration of dependency on PHPUnit in package.json.
But the presence of @expectedException implicitly limits the PHPUnit version to < 9.0 , so it will break CI of other packages which inherits LoggerInterfaceTest.
e.g. https://travis-ci.org/Seldaek/monolog/jobs/628326254#L384 (not broken yet, but will be broken )

IMHO It's time to consider whether having abstract class LoggerInterfaceTest extends TestCase without explicit version constraint is good or not.

We actually discussed this multiple times, but the crucial point here is that we would need to split the tests into a separate package probably.

Agree.

Then we don't need this PR any more.
