PHPUnit assertGreaterThan()函数

assertGreaterThan()函数是 PHPUnit 中的内置函数，用于断言实际值是否大于预期值。如果实际值大于预期值，则此断言将返回 true，否则返回 false。如果为真，则断言的测试用例通过，否则测试用例失败。

句法：

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

参数：此函数接受三个参数，如上述语法所示。参数说明如下：

$expected：此参数是表示预期数据的任何类型的数值。
$actual：此参数是代表实际数据的任何类型的数值。
$message：此参数采用字符串值。当测试用例失败时，此字符串消息显示为错误消息。

下面的程序说明了 PHPUnit 中的 assertGreaterThan()函数：

方案一：

PHP

assertGreaterThan( 
            $expected, 
            $actual, 
            "actual value is not greater than expected"
        ); 
    } 
} 
    
?>

PHP

assertGreaterThan( 
            $expected, 
            $actual, 
            "actual value is not greater than expected"
        ); 
    } 
} 
    
?>

输出：

方案二：

PHP

            "actual value is not greater than expected"
        ); 
    } 
}
