PHPUnit assertStringEndsNotWith() Function
  • Last Updated : 07 Aug, 2020

The assertStringEndsNotWith() function is a builtin function in PHPUnit and is used to assert whether the actual string doesn’t end with expected suffix string. This assertion will return true in the case if the actual string doesn’t end with expected suffix string else returns false. In case of true the asserted test case got passed else test case got failed.

Syntax:

assertStringEndsNotWith(string $suffix, string $string
[, string $message = ''])

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

  • $expectedsuffix: This parameter is of any type which represents the expected suffix string.
  • $actualstring: This parameter is of any type which represents the actual string.
  • $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 assertStringEndsNotWith() function in PHPUnit:

Example 1:



PHP




<?php 
use PHPUnit\Framework\TestCase; 
    
class GeeksPhpunitTestCase extends TestCase 
    public function testNegativeTestcaseForassertStringEndsNotWith()
    
        $expectedsuffix = ('th');
        $actualstring = ('4th');
    
        // Assert function to test whether expected suffix
        // string doesn't ends with actual string content
        $this->assertStringEndsNotWith(
            $expectedsuffix,
            $actualstring
            "actual string content doesn't ends with 
             expected suffix content"
        ); 
    
    
?>

Output:

PHPUnit 8.5.8 by Sebastian Bergmann and contributors.

F                                                          1 / 1 (100%)

    public function testPositiveTestcaseForassertStringEndsNotWith()
    
        $expectedsuffix = ('rd');
        $actualstring = ('4th');
    
        // Assert function to test whether expected suffix
        // string doesn't ends with actual string content
        $this->assertStringEndsNotWith(
            $expectedsuffix,
            $actualstring
            "actual string content doesn't ends with
