PHPUnit assertGreaterThanOrEqual()函数

assertGreaterThanOrEqual()函数是 PHPUnit 中的内置函数，用于断言实际获得的值是否大于或等于期望值。如果实际值大于或等于预期值，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：

assertGreaterThanOrEqual(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 assertGreaterThanOrEqual()函数：

示例 1：

PHP

assertGreaterThanOrEqual( 
            $expected, 
            $actual, 
            "actual value is greater than or equal to expected"
        );
          
    }
   
  
      
    public function testNegativeForassertGreaterThanOrEqualWithGreaterVal()
    {  
     $expected = 22; 
        $actual = 10;
        // Assert function to test whether actual
        // value is greater than or equal to expected or not 
          
        $this->assertGreaterThanOrEqual( 
            $expected, 
            $actual, 
            "actual value is greater than or equal to expected"
        ); 
    }  
 } 
?>
