PHP PHPUnit assertStringStartsNotWith()用法及代碼示例

assertStringStartsNotWith()函數是PHPUnit中的內置函數，用於斷言實際字符串是否不是以預期的前綴字符串開頭。如果實際字符串不是以預期的前綴字符串開頭，則該斷言將返回true，否則返回false。如果為真，則通過斷言的測試用例，否則測試用例失敗。

用法:

assertStringStartsNotWith(string $prefix, 
string $string[, string $message = ''])

參數：此函數接受上述和以下所述的三個參數：

$expectedprefix:此參數可以是代表所需前綴字符串的任何類型。
$actualstring:此參數可以是代表實際字符串的任何類型。
$message:此參數采用字符串值。當測試用例失敗時，此字符串消息將顯示為錯誤消息。

以下示例說明了PHPUnit中的assertStringStartsNotWith()函數：

範例1：

PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeTestcaseForassertStringStartsNotWith() 
    {  
        $expectedprefix = ('dis'); 
        $actualstring = ('disagree'); 
    
        // Assert function to test whether  
        // actual string content doesn't starts  
        // with expected prefix string content 
        $this->assertStringStartsNotWith( 
            $expectedprefix, 
            $actualstring,  
            "actual string content doesn't start with  
             expected prefix content" 
        );  
    }  
}  
    
?>
