PHPUnit | assertClassHasStaticAttribute() function
  • Last Updated : 19 Jul, 2019

The assertClassHasStaticAttribute() function is a builtin function in PHPUnit and is used to assert a class having a static attribute. This assertion will return true in the case if the class contains the provided attribute as static element else return false and in case of true the asserted test case got passed else test case got failed.

Syntax:

assertClassHasStaticAttribute(string $attributeName, string $className, string $message = ''])

Parameters: This function accepts three parameters as shown in the above syntax. The parameters are described below:

  1. $attributeName: This parameter represents the attributeName to be attribute of class in array.
  2. $className: This parameter is a class name for which the assert function will check whether it contains attribute or not.
  3. $message: This parameter takes string value. When the testcase got failed this string message got displayed as error message.

Below programs illustrate the assertClassHasStaticAttribute() function:

Program 1:






<?php
use PHPUnit\Framework\TestCase;
  
// test class
Class testClass{
    public static $attribute = "test attribute";
}
  
class GeeksPhpunitTestCase extends TestCase
{
    public function testNegativeTestcaseForClassHasStaticAttribute()
    {
        // assert function to test whether 'geeks' is a attribute of testclass
        $this->assertClassHasStaticAttribute('geeks', "testClass", "testClass doesn't has geeks as static attribute") ;
    }
}
?>

Output:

PHPUnit 6.5.5 by Sebastian Bergmann and contributors.
