        Why is this an issue?

        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());
        }
