PHP PHPUnit assertIsNotString()用法及代码示例

assertIsNotString()函数是PHPUnit中的内置函数，用于断言实际获得的值是否为非字符串值。如果实际值为Not Not else，则该断言将返回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:

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

参数：此函数接受上述和以下描述的两个参数：

• $actualvalue:此参数可以是代表实际数据的任何类型。
• $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。

以下示例说明了PHPUnit中的assertIsNotString()函数：

范例1：

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeTestcaseForassertIsNotString() 
    { 
        $actualvalue = "22";  
    
        // Assert function to test whether given  
        // actualvalue is a string or not 
        $this->assertIsNotString( 
          $actualvalue, 
          "actualvalue is a string or not"
        );  
    }  
}  
    
?>

        $actualvalue = 420;  
    
        // Assert function to test whether given  
        // actualvalue is a string or not 
        $this->assertIsNotString(
