Testing Exceptions
Example
// PHPUnit
$this->expectException(InvalidArgumentException::class);
$this->expectExceptionMessage("Age must be positive");
$this->expectExceptionCode(422);
createUser(["age" => -1]);
// Pest
expect(fn() => createUser(["age" => -1]))
->toThrow(InvalidArgumentException::class, "Age must be positive");
// Assert no exception
$this->expectNotToPerformAssertions();
createUser(["age" => 25]); Pro Tip
expectException must be called before the code that throws — it does not catch retroactively.
