PHP PHPUnit assertStringNotContainsStringIgnoringCase()用法及代码示例

assertStringNotContainsStringIgnoringCase()函数是PHPUnit中的内置函数，用于断言字符串不包含子字符串，而忽略了子字符串的大小写。如果字符串不包含子字符串作为忽略区分大小写的子字符串，则该断言将返回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:

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

参数：该函数接受三个参数，如上面的语法所示。参数说明如下：

• $substring:此参数表示字符串是给定字符串的子字符串。
• $string:此参数是一个字符串，assert函数将对其检查其是否包含子字符串(忽略大小写)。
• $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assertStringNotContainsStringIgnoringCase()函数：

程序1:

<?php 
use PHPUnit\Framework\TestCase; 
  
class GeeksPhpunitTestCase extends TestCase 
{ 
    public function testNegativeTestcaseForAssertStringNotContainsStringIgnoringCase() 
    { 
        $testString = "geekforgeek"; 
        $substring = "gEek";  
          
        // Assert function to test whether 'geek' is a substring of 
        // testString ignoring case-sensitivity 
        $this->assertStringNotContainsStringIgnoringCase( $substring, $testString, 
                "testString contains 'gEek' as substring" ); 
    } 
} 
  
?>

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assertStringNotContainsStringIgnoringCase()。
