        Why is this an issue?

        PHPUnit assertions do throw a PHPUnit\Framework\ExpectationFailedException exception when they fail. This is how PHPUnit internally notices when assertions within testcases fail. However, if such an exception type or one of its parent types is captured within a try-catch block and not rethrown, PHPUnit does not notice the assertion failure.

        This check raises an issue on assertions within the try body of a try-catch block that do catch exceptions of the type PHPUnit\Framework\ExpectationFailedException, PHPUnit\Framework\AssertionFailedError, or Exception, and do not handle the variable holding the exception.

        Noncompliant code example

        public function testA() {
            try {
                assertTrue(getValue()); // Noncompliant
            } catch (\PHPUnit\Framework\ExpectationFailedException $e) {
        
            }
        }
        

        Compliant solution

        public function testB() {
            try {
                assertTrue(getValue()); // Compliant
            } catch (\PHPUnit\Framework\ExpectationFailedException $e) {
                assertEquals("Some message", $e->getMessage());
            }
        }
