PHPUnit

phpunit testing:

• https://www.youtube.com/watch?v=-9YVcssCACI&t=244s
• Installation:
  • composer require –dev phpunit/phpunit
• Usage on cli:
  • If it’s installed with composer in your project folder:
    • go to your project folder
      • .\vendor\bin\phpunit phptest.php 
• phpunit config file:
  • create phpunit.xml
  • specify the testsuite (filename, location etc)
  • from the cli just use .\vendor\bin\phpunit
  • file content
• Can use gruntjs for running phpunit
• Accessing Main Class from Test Class
  • Autoload the main class location in composer.json
    • “autoload”:{
      “psr-4”:{
      “App\\”:”app”
      }
      }
    • where ‘app’ is the folder location of the main class
    • PSR 4 app loading:
      • http://www.php-fig.org/psr/psr-4/
    • after specifying autoload execute following composer command to work with autoloaded classes
      • composer dump-autoload -o
  • Using the main class in Test class
    • create object $obj= new \App\ClassName; (fresh model for each method)
    • User the $obj to access the class properties
  • Naming for test methods:
    • ‘test’ has to be pre-fixed for all test class methods and has camel case methods
    • dot block method:
      • /** @test */
      • inserting this dot block before a method which has no ‘test’ pre-fix will run the test like other test cases which has ‘test’ pref-fix
  • Using setUp as a constructor method for creating a model with a protected variable
    • setUp runs before each method
    • protected $user;public function setUp(){
      $this->user = new \App\Models\User;
      }
  • Collection class
    • convenient wrapper for any kind of objects
    • for iterating purposes
  • Important concepts:
    • namespace
      • http://php.net/manual/en/language.namespaces.php
    • use
      • http://php.net/manual/en/language.namespaces.importing.php
  • Assertions:
    1. assertTrue
    2. assertEquals
    3. assertEmpty
    4. assertInstanceOf
    5. assertCount
    6. assertInternalType
  • Exceptions:
    1. expectExceptions
