PHPUnit assertNotEqualsIgnoringCase() Function

  • Last Updated : 17 Aug, 2020

The assertNotEqualsIgnoringCase() function is a builtin function in PHPUnit and is used to assert whether the expected string is not equal to actual string but ignoring the case. This assertion will return true in the case if the actual string is not equal to expected string ignoring case-sensitivity, else return false. In case of true the asserted test case got passed else test case got failed.

syntax:

assertnotEqualsIgnoringCase(mixed $expected, 
        mixed $actual[, string $message = '']

Parameters: This function accepts three parameters as mentioned above and described below:

  • $expected: This parameter is a string that represents the expected data.
  • $actual: This parameter is a string that 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 programs illustrate the assertnotEqualsIgnoringCase() function:

Example 1:



PHP




<?php 
use PHPUnit\Framework\TestCase; 
    
class GeeksPhpunitTestCase extends TestCase 
    public function testNegativTestcaseForAssertNotequalIgnoringCase() 
    
        $expected = "Geeks"
        $actual= "geEks";  
        // assert function to test whether expected
        // is not equals to actual ignoring case
        $this->assertNotEqualsIgnoringCase(
            $actual
            $expected,
        "expected string is equal to actual ignoring case" ) ; 
    
    
?> 

Output:
