In PHPUnit, to test that an exception is thrown in a given piece of code, the expectException*() methods or the @expectedException* annotations can be used. For such a test to succeed, something in the test method has to throw an exception with the awaited properties. Having an assertion at the end of such a test method, means that, if the test succeeds, that assertion was never evaluated because an exception was thrown before getting to that point.

Noncompliant Code Example

public function testA() {
    $o = new MyClass();
    $this->expectException(\Exception::class);
    $o->doSomething();
    $this->assertTrue($o->hasProperty()); // Noncompliant - This assertion might never get evaluated
}

Compliant Solution

public function testA() {
    $o = new MyClass();
    $this->expectException(\Exception::class);
    $o->doSomething();
}

public function testB() {
    $o = new MyClass();
    $this->assertTrue($o->hasProperty());
}
