PHP PHPUnit assertGreaterThan()用法及代码示例

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

用法:

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

参数：该函数接受三个参数，如上面的语法所示。参数说明如下：

$expected:此参数可以是代表期望数据的任何类型的数值。
$actual:此参数可以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，此字符串消息将显示为错误消息。

以下示例程序旨在说明PHPUnit中的assertGreaterThan()函数：

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"
        );  
    }  
}  
    
?>

输出：

程序2:

PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testPositiveTestcaseForassertGreaterThan() 
    {    $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"
        );  
    }  
}  
    
?>

输出：
