PHP PHPUnit assertStringContainsStringIgnoringCase()用法及代码示例


assertStringContainsStringIgnoringCase()函数是PHPUnit中的内置函数,用于断言包含子字符串的字符串,而忽略子字符串的大小写。如果字符串包含子字符串作为忽略区分大小写的子字符串,则此断言将返回true;否则返回false;如果为true,则断言的测试用例通过,否则测试用例失败。

用法

assertStringContainsStringIgnoringCase(string $substring, string $string, string $message = ''])

参数:该函数接受三个参数,如以上语法所示。参数说明如下:


  1. $substring:此参数表示字符串是给定字符串的子字符串。
  2. $string:此参数是字符串,断言函数将检查其是否包含子字符串(忽略大小写)。
  3. $message:此参数采用字符串值。当测试用例失败时,此字符串消息将显示为错误消息。

以下示例程序旨在说明assertStringContainsStringIgnoringCase()函数:

程序1:

<?php 
use PHPUnit\Framework\TestCase; 
  
class GeeksPhpunitTestCase extends TestCase 
{ 
    public function testNegativeTestcaseForAssertStringContainsStringIgnoringCase() 
    { 
        $testString = "geekforgeek"; 
        $substring = "geeks";  
        // assert function to test whether 'geeks' is a substring of testString ignoring case-sensitivity 
        $this->assertStringContainsStringIgnoringCase($substring, $testString, "testString doesn't contains 'geeks' as substring") ; 
    } 
} 
  
?>

输出:

PHPUnit 8.2.5 by Sebastian Bergmann and contributors.

FAILURES!
Tests:1, Assertions:1, Failures:1.

程序2:

<?php 
use PHPUnit\Framework\TestCase; 
  
class GeeksPhpunitTestCase extends TestCase 
{ 
    public function testPositiveTestcaseForAssertStringContainsStringIgnoringCase() 
    { 
        $testString = "geekforgeek"; 
        $substring = "geEk";  
        // assert function to test whether 'gEek' is a substring of testString 
        $this->assertStringContainsStringIgnoringCase($substring, $testString, "testString doesn't contains 'geEk' as substring") ; 
    } 
} 
  
?>

输出:

PHPUnit 8.2.5 by Sebastian Bergmann and contributors.

.                                                                   1 / 1 (100%)

OK (1 test, 1 assertion)

注意:要使用phpunit运行测试用例,请遵循此处的步骤。另外,phpunit 7及更高版本支持assertStringContainsStringIgnoringCase()。
