Developers write tests for a variety of different reasons and understanding why, and how, writing tests can improve the quality of our code and our sanity helps motivate ourselves to write tests. The tests we write usually take one of two forms. Functional tests are used to test an applications behavior. When I click this link does it take me to the about page? Unit tests are used to verify the logic within a small segment, or unit, of code. When I call this function that is supposed to return a link with these specific parameters does it return the correct data? There are a ton of reasons that investing time and resources into writing automated tests is a big win in the long run and in this lesson we'll cover a bunch of them, including:
- Eliminate repetitive tasks.
- Improve overall stability of an application.
- Ensure critical paths & edge cases function.
- Reduce (not eliminate) the number of tests that need to be performed manually.
Types of Tests
There are are two main types of tests and we're going to be writing. Functional tests, and Unit tests.
Functional tests, also known as integration tests, test the functionality of a particular aspect of an application by simulating normal interaction with that system. In the case of web software this usually refers to simulating a user navigating and interacting with the website as if they where using their browser, keyboard, and mouse.
Unit testing is the art and practice of taking a small portion of code, a unit, and subjecting it to programmatic tests to prove its correctness. For example, testing a function that performs unit conversion by comparing a known input with an anticipated result.
UPDATE: This video references qa.drupal.org which is no longer in use. On Friday, October 23rd 2015 - qa.drupal.org received and processed it's last
test. The qa.drupal.org testbots have now been superseded by DrupalCI - and test results are now displayed directly on Drupal.org. While the mechanics are different now, the end result is still all patches to Drupal core are automatically tested.
Over the years we've developed some techniques for practicing that we wanted to share. At Drupalize.Me we take hugging seriously. In this tutorial we'll look at the art, and science, of giving a good hug. The Merriam Webster dictionary defines the word hug as; squeeze (someone) tightly in one's arms, typically to express affection.
Did you know there are all kinds of different hugs that you can give? In this tutorial we'll look at:
- Defining what a hug is
- Some of the many types of hugs in the world today
- Precautions you may want to familiarize yourself with before hugging
- And the importance of proper technique
Lets go ahead and get started shall we?
