PHP PHPUnit assertStringMatchesFormat()用法及代碼示例

assertStringMatchesFormat()函數是PHPUnit中的內置函數，用於斷言給定的字符串是否與格式匹配。如果給定的字符串與格式類型匹配，則此斷言將返回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:

assertStringMatchesFormat(string $format, string $string[, string $message = ''])

參數：此函數接受上述和以下所述的三個參數：

$format:此參數表示數據的預建立布局。
$string:此參數可以是表示字符串的任何類型。
$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assertStringMatchesFormat()函數：

範例1：

PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeTestcaseForassertStringMatchesFormat() 
    {  
        $format =  "%d";  
        $String  =  "hh"; 
        
        // Assert function to test whether given  
        // string is matched with type of format or not 
        $this->assertStringMatchesFormat( 
            $format, 
            $String, 
            " given string is matched with type  
              of format or not" 
        );
