Drupal code: Drupal hints and tips

  • Contribute to Drupal(.org)!

    So at DrupalCon Austin I had a great time at the contribution sprints. I worked on some issues affecting Drupal.org, it was great fun!

    The issues we worked on over the week range from simple things through to some pretty difficult issues.

    Although Drupal core can always use more contributors, I would suggest that Drupal.org is also desperately short of contributors too.

  • Language lessons: What are you translating?

    Content (node-level) translation or entity (field-level) translation?

    It seems an obvious question to ask, but what are you translating?

    The tools exist to translate just about anything in Drupal 7*, but in many different ways, so you need to know exactly what you're translating. Language is 'a first-class citizen', in the sense that any piece of text is inherently written by someone on some language, which Drupal 7 is built to recognise. Sometimes you want to translate each & every individual piece of text (e.g. at the sentence or paragraph level). Other times you want to translate a whole page or section that is made up of multiple pieces of text.

    Part 8: CasperJS debugging tips

    You're getting desperate. Your CoffeeScript / Javascript syntax looks OK, but CasperJS doesn't like what you're giving it.

    Try going through this checklist for a selection of sensible sanity checks and more:

    Part 7: When this.mouse.click doesn't work

    mouse.click and mouse.move are a really helpfuls function in CasperJS, but we have at times found that they just don't work. Mostly, that's been because the element isn't there to click on. Do make sure that it's actually there! Make sure you're using the right selector, too. Try a casper.capture() to see whether it's there, but be wary of timings to ensure that you get a capture for the moment that you want to be performing the mouse action.

  • A fully-automated testing rig #6

    Part 6: Manually fail a test, but continue script execution

    We set up an event to take screenshots of failed test pages, by hooking into the onFail event. This made for a problem when we wanted to pass or fail a test based on whether there were entries in the Drupal Watchdog table. Failing a test also would normally stop script execution, but we explicitly need our post script to finish its work!

  • A fully-automated testing rig #5

    Part 5: Fun with viewports, and THEN some

    As I described previously, we nicely externalised our list of viewport sizes, making it really easy to set our viewports for mobile, tablet and desktop tests. Our content appearance tests put this to good use, taking screenshots of the content at mobile, tablet and desktop resolutions. The problem we very quickly ran into was that we frequently ended up with empty screenshots, or sometimes no screenshot at all. This is where the asynchronous fun began.

  • A fully-automated testing rig #4

    Part 4: When TrueType doesn't fix everything

    Two fonts walk into the bar, and the barman says, “Sorry lads, we don’t serve your type.”

    It was a good day. I'd finished writing up the basic appearance tests for the first batch of content types, I'd road-tested them on my machine, we'd set up Jenkins… all was ready to go for our first run on the server. When we ran it, however, all the tests failed against the baseline.

    Every single one.

  • A fully-automated testing rig #3

    Part 3: Using other scripts, datasources and directories

    Earlier I described a bit about the scope of the project and how careful planning would be needed to keep the project growing smoothly. One result of this is our test template - a basic test script outline which most scripts should stick to - which makes test scripts easier to update because they all follow the same structure (yay standardisation!).

  • A fully-automated testing rig #2

    Part 2: Setting up for a large project

    When you take on a project it's a good idea to make sure you plan ahead. Testing platforms only remain useful as long as they're considered dependable - if it becomes too difficult to write tests which don't reliably execute you might as well not bother.

    Here are a few key things I set up at the start to help the project along, which have all been hugely worthwhile investments:

  • A fully-automated testing rig #1

    A quick introduction

    A few months ago I started my first project with CasperJS and PhantomCSS, and what an interesting experience it has been working through that to now our second, larger, automated testing setup. Being young projects, there are some fun quirks and niggles in CasperJS and PhantomCSS that I wish the world could have warned me about.
