How to check that a method threw an exception in PHPUnit?

Hello everyone! I've just started learning PHPUnit and writing tests for my project. I have a method that should throw an exception under certain conditions, for example, `InvalidArgumentException` if an invalid argument is passed. The problem is that I can't figure out how to properly write an assert that checks that the exception was thrown. I tried wrapping the method call in a `try...catch` and then doing `$this->assertTrue($caught)`, but that looks messy and doesn't use PHPUnit's capabilities. Here's an example of my code: ```php class Calculator { public function divide($a, $b) { if ($b == 0) { throw new \InvalidArgumentException('Division by zero.'); } return $a / $b; } } ``` And my test, which checks the exception in an ugly way
