Acceptance & Functional Testing with Codeception - SunshinePHP 2016
3 likes3,592 views
The document discusses using Codeception for acceptance and functional testing. It introduces Codeception and the different types of testing including unit, functional, and acceptance testing. It then provides examples of writing functional tests for a login feature and acceptance tests using PhantomJS to test interactions on a real browser. Screenshots are included when acceptance tests fail to help debug issues.

Acceptance & Functional Testing with Codeception - SunshinePHP 2016
- 1. Acceptance & Functional Testing with Codeception Joe Ferguson February 6th 2015
- 2. Who Am I? Joe Ferguson PHP Developer Twitter: @JoePFerguson Organizer of @MemphisPHP @NomadPHP Lightning Talks Passionate about Community
- 3. One late night coding session of fighting with tests…
- 4. I found
- 6. Example Test Sample taken from http://codeception.com
- 8. Codeception • Selenium WebDriver integration • Elements matched by name, CSS, XPath • Symfony2, Laravel, Yii, Phalcon, Zend Framework • PageObjects and StepObjects included • BDD-style readable tests • Powered by PHPUnit • API testing: REST,SOAP,XML-RPC • Facebook API testing • Data Cleanup • HTML, XML, TAP, JSON reports • CodeCoverage and Remote CodeCoverage • Parallel Execution
- 10. Unit Testing In computer programming, unit testing is a software testing method by which individual units of source code, sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures, are tested to determine whether they are fit for use. https://en.wikipedia.org/wiki/Unit_testing
- 11. Functional Testing Functional testing is a quality assurance (QA) process and a type of black box testing that bases its test cases on the specifications of the software component under test. Functions are tested by feeding them input and examining the output, and internal program structure is rarely considered (not like in white-box testing). Functional testing usually describes what the system does. Functional testing does not imply that you are testing a function (method) of your module or class. Functional testing tests a slice of functionality of the whole system https://en.wikipedia.org/wiki/Functional_testing
- 12. Acceptance Testing In engineering and its various subdisciplines, acceptance testing is a test conducted to determine if the requirements of a specification or contract are met. In software testing the ISTQB defines acceptance as: formal testing with respect to user needs, requirements, and business processes conducted to determine whether or not a system satisfies the acceptance criteria and to enable the user, customers or other authorized entity to determine whether or not to accept the system. Acceptance testing is also known as user acceptance testing (UAT), end-user testing, operational acceptance testing (OAT) or field (acceptance) testing. https://en.wikipedia.org/wiki/Acceptance_testing
- 13. How I think about types Unit tests test your functions and methods. Functional tests test parts of your application. Acceptance tests test your interactions.
- 14. Isn’t unit testing enough?
- 15. It might be, how high is your coverage?
- 16. How do you know methods work together?
- 17. Functional tests allow you to test individual scenarios in your application
- 18. Acceptance tests allow you to test the interactions in your application
- 19. Where do we start?
- 22. Better way to install* *http://blog.doh.ms/2014/10/13/installing-composer-packages
- 23. Add to PATH
- 26. Run Codeception
- 28. Codecept build
- 29. Our First Test
- 30. Login Form
- 33. Writing our test
- 34. Click on what? Click on ‘Copy CSS Path’
- 35. How to run tests codecept run // runs all tests codecept run functional // run functional tests codecept run functional tests/functional/ AdminCanLoginCept.php // run single test Can also add -vv or -vvv for detailed output
- 36. Run our test
- 37. What are we testing? The route ‘auth/login’ shows us a login form Submitting login form performs some action Dashboard (after successful login) displays Some success text exists “Hello admin!”
- 38. What are we NOT testing? Navigation on the page “Remember Me” functionality works Password Reset works User is actually an admin
- 39. Functional testing tests a slice of functionality of the whole system
- 40. We don’t care about Navigation on the page “Remember Me” functionality works Password Reset works User is actually an admin
- 41. We care about $I->wantTo('ensure an admin can log in');
- 42. What if our test fails?
- 44. Run Our test
- 46. Test will pass when… the user exists in the database the routes (get & post) work login form view renders properly dashboard view renders properly
- 48. Using Laravel5 Module amOnAction is translated to the /auth/login url
- 49. Test Passes
- 50. Check the DB for user seeRecord() will fail if the user does not exist
- 51. User is in the database
- 52. Check for errors Useful for checking that error messages are returned dontSee() ensures text does not exist on view
- 53. Testing your API
- 55. Test API Create User http://codeception.com/docs/10-WebServices
- 56. Now we know slices of our application work
- 60. Add PhantomJS
- 62. Export your Database php artisan migrate php artisan db:seed mysqldump -u homestead -psecret homestead > tests/_data/dump.sql
- 63. Our 1st acceptance test
- 64. Test passes
- 65. That looks a lot like our functional test!
- 67. Functional Test runs via PhpBrowser
- 68. Acceptance Test runs via PhantomJS
- 70. Use XPath to submit form
- 74. Using XPath for form fields isn’t very easy to read. XPath isn’t very easy to read…
- 75. When to use XPath? When you can’t add an ID or Class on an element When you want to ensure styles/formatting (error messages, flash messages, etc) When testing navigation elements When testing any dynamic elements
- 76. Acceptance failures come with screenshots!
- 77. Log in and look for content that doesn’t exist
- 78. Test Failed!
- 79. We see our content does not exist on the page
- 80. Some issues… PhantomJS pretty broken on Travis-CI Acceptance tests are SLOW (and memory hogs) Acceptance tests aren’t unit tests, it can be hard to find WHAT is causing the tests to fail Functional & Acceptance tests aren’t replacements for unit tests, but can be easier to write if your app isn’t written to be testable
