In PHPUnit, you can use the assertNotEquals()
or assertNotSame()
methods to test for inequality.
1
|
$this->assertNotEquals($expected, $actual); |
Here, $expected
is the expected value and $actual
is the value that is being tested. The assertion will pass if the two values are not equal.
1
|
$this->assertNotSame($expected, $actual); |
Similarly, $expected
is the expected object or value, and $actual
is the value being tested. The assertion will pass if the two objects or values are not the same.
Example usage:
1 2 3 4 5 6 7 |
// Test for inequality with assertNotEquals $this->assertNotEquals(5, 10); // Passes $this->assertNotEquals('abc', 'abc'); // Fails // Test for inequality with assertNotSame $this->assertNotSame($obj1, $obj2); // Passes $this->assertNotSame(5, 5); // Fails |
You can also provide an optional custom message as the last argument to these methods to provide additional information about the assertion:
1 2 |
$this->assertNotEquals($expected, $actual, 'The values should not be equal'); $this->assertNotSame($expected, $actual, 'The objects should not be the same'); |
Note that these methods are available as part of the PHPUnitFrameworkTestCase
class, so make sure your test class extends this class.
