PHPUnit assertLessThan()函数

assertLessThan()函数是 PHPUnit 中的内置函数,用于断言实际获取的值是否小于预期值。如果实际值小于预期值,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:

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

参数:此函数接受三个参数,如上所述,如下所述:

  • $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。

下面的例子说明了 PHPUnit 中的 assertLessThan()函数:

示例 1:

PHP
assertLessThan( 
            $expected, 
            $actual, 
            "actual value is not less than expected"
        ); 
    } 
} 
    
?>


PHP
assertLessThan( 
            $expected, 
            $actual, 
            "actual value is not less than expected"
        ); 
    } 
} 
    
?>


输出:
