PHPUnit assertIsScalar()函数

assertIsScalar()函数是 PHPUnit 中的内置函数,用于断言标量变量是包含整数、浮点数、字符串或布尔值的变量。此函数不认为 null 是标量。如果实际值为标量,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:

assertIsScalar($actual[, $message = ''])

参数:此函数接受两个参数,如下所述:

  • $actual:此参数是代表实际数据的任何类型的字符串或变量。
  • $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 assertIsScalar()函数:

示例 1:

PHP
assertIsScalar(
          
            $actualvalue, 
            "actual value is a scalar or not"
        );
          
    }
   
 } 
?>


PHP
assertIsScalar(
          
            $actualvalue, 
            "actual value is a scalar or not"
        );
          
    }
  
  
     public function testNegativeForassertIsScalar()
    {   
     $actualvalue = 420;
            // Assert function to test whether actual 
        // value is a integer or not
        $this->assertIsScalar(
          
            $actualvalue, 
            "actual value is a scalar or not"
        );
          
    }
   
 } 
?>


输出:

PHPUnit 8.5.8 by Sebastian Bergmann and contributors.

示例 2:

assertIsScalar(
          
            $actualvalue, 
            "actual value is a scalar or not"
        );
          
    }
  
  
     public function testNegativeForassertIsScalar()
    {   
     $actualvalue = 420;
            // Assert function to test whether actual 
        // value is a integer or not
        $this->assertIsScalar(
          
            $actualvalue, 
            "actual value is a scalar or not"
        );
          
    }
   
 } 
?>
