PHP PHPUnit assertGreaterThan()用法及代碼示例

assertGreaterThan()函數是PHPUnit中的內置函數，用於斷言實際值是否大於期望值。如果實際值大於期望值，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:

assertGreaterThan(mixed $expected, 
         mixed $actual[, string $message = ''])

參數：該函數接受三個參數，如上麵的語法所示。參數說明如下：

$expected:此參數可以是代表期望數據的任何類型的數值。
$actual:此參數可以是代表實際數據的任何類型的數值。
$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。

以下示例程序旨在說明PHPUnit中的assertGreaterThan()函數：

程序1:

PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeTestcaseForassertGreaterThan() 
    {    $expected = 44;  
        $actual = 22; 
    
        // Assert function to test whether expected  
        // value is greater than actual or not  
        $this->assertGreaterThan(  
            $expected,  
            $actual,  
            "actual value is not greater than expected"
        );  
    }  
}  
    
?>

    {    $expected = 22;  
        $actual = 44; 
    
        // Assert function to test whether expected  
        // value is greater than actual or not  
        $this->assertGreaterThan(  
            $expected,  
            $actual,  
            "actual value is not greater than expected"
        );  
    }  
}  
    
?>
