The following programs illustrate the assertNotEquals() function in PHPUnit: Program 1: use PHPUnitFrameworkTestCase; class GeeksPhpunitTestCase extends TestCase { public function testNegativeTestcaseForAssertNotEquals() { $expected = " engineer " ; $actual = "engineer" ; // Submit function to check if expected // value does not match actual or not $this -> assertNotEquals ( $expected , $actual , "actual value is equals to expected"); } }
?> Output:PHPUnit 8.2.5 by Sebastian Bergmann and contributors. F 1/1 (100%) Time: 67 ms, Memory: 10.00 MB There was 1 failure: 1) GeeksPhpunitTestCase::testNegativeTestcaseForAssertNotEquals actual value is equals to expected Failed asserting that ’engineer’ is not equal to’ engineer’. /home/shivam/Documents/engineer/phpunit/abc.php:15 FAILURES!

Program 2: use PHPUnitFrameworkTestCase; class GeeksPhpunitTestCase extends TestCase { public function testPositiveTestcaseForAssertNotEquals() { $expected = " engineer " ; $actual = "Geeks" ; // Submit function to check if expected // value does not match actual or not $this -> assertNotEquals ( $expected , $actual , "actual value is not equals to expected"); } }

Note: To run testcases with PHPUnit steps follows from here . Also assertNotEquals() is supported by phpunit 7 and up.
