PHP PHPUnit assertStringEqualsFile()用法及代碼示例

assertStringEqualsFile()函數是PHPUnit中的內置函數，用於斷言所獲得的實際字符串內容是否等於預期的文件。如果預期的文件內容與實際的字符串內容相同，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:

assertStringEqualsFile(string $expectedFile, 
string $actualString[, string $message = ''])

參數：此函數接受上述和以下所述的三個參數：

$expectedfile:此參數可以是代表所需文件的任何類型。
$actualstring:此參數可以是代表實際字符串內容的任何類型。
$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assertStringEqualsFile()函數：

範例1：

PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeTestcaseForassertStringEqualsFile() 
    {  
        $expectedfile = "/home/lovely/Documents/php/abc"; 
        $actualstring = "File has geeksforgeeks";  
    
        // Assert function to test whether  
        // expected file content is equal to  
        // actual string content or not  
        $this->assertStringEqualsFile( 
            $expectedfile, 
            $actualstring,  
            "actual string content is equals to 
             expected file content or not" 
        );  
    }  
}  
    
?>

輸出：
