PHP PHPUnit assertIsBool()用法及代码示例


assertIsBool()函数是PHPUnit中的内置函数,用于断言实际获得的值是否为Bool。如果实际值为Bool,则此断言将返回true,否则Bool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:

assertIsBool($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assertIsBool()函数:

范例1:



PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeForassertIsNotBooltrue() 
    {    $actual = 420; 
        // Assert function to test whether actual  
        // value is (true or false) or not 
        $this->assertIsBool(  
          
            $actual,  
            "actual value is Bool or not"
        ); 
          
    } 
      
    public function testNegativeForassertIsNotBoolFalse() 
    {   
        $actual = 220; 
        // Assert function to test whether actual 
        // value is (true or false) or not 
          
        $this->assertIsBool(  
          
            $actual,  
            "actual value is Bool or not"
        ); 
    }   
 }  
?> 

输出:

PHPUnit 8.5.8 by Sebastian Bergmann and contributors.

范例2:

PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testPositiveForassertIsNotBooltrue() 
    {    $actual = true; 
        // Assert function to test whether actual  
        // value is (true or false) or not 
        $this->assertIsBool(  
          
            $actual,  
            "actual value is Bool or not"
        ); 
          
    } 
   
  
      
    public function testPositiveForassertIsNotBoolFalse() 
    {   
        $actual = false; 
        // Assert function to test whether actual 
        // value is (true or false) or not 
          
        $this->assertIsBool(  
          
            $actual,  
            "actual value is Bool or not"
        ); 
    }   
 }  
?> 

输出:

PHPUnit 8.5.8 by Sebastian Bergmann and contributors.
