The assertNotSame() function is a builtin function in PHPUnit and is used to assert the actually obtained value to be not-same to the expected value. This assertion will return true in the case if the expected value is not-same to actual value else returns false. In case of true the asserted test case got passed else test case got failed.
Syntax:
assertNotSame( mixed $expected, mixed $actual, string $message = '' )
Parameters: This function accepts three parameters as shown in the above syntax. The parameters are described below:
- $expected: This parameter is of any type which represents the expected data.
- $actual: This parameter is of any type which represents the actual data.
- $message: This parameter takes a string value. When the test case got failed this string message got displayed as an error message.
Below examples illustrate the assertNotSame() function in PHPUnit:
Example 1:
PHP
<?php use PHPUnit\Framework\TestCase;
class GeeksPhpunitTestCase extends TestCase
{ public function testNegativeForassertNotSame()
{
$expected = "(108) mango" ;
$actual = "(108) mango" ;
// Assert function to test whether expected
// value is same as actual value or not
$this ->assertNotSame(
$expected ,
$actual ,
"actual value is same to expected"
);
}
}
?> |
