Help Wanted: Unit & Functional Tests

Hello Pixi Devs!

We’re looking for some PRs from folks to help increase our test-coverage or Pixi.js. Why are unit-tests helpful? Many reasons, but here are a few:

• they help us spot issues sooner (with Travis and running npm test)
• they improve the stability of code over time
• they aid in doing major refactoring efforts

Let’s be frank, our test-coverage right now is pretty poor. Until now, we hadn’t realized just how poor. We have just merged PR #3041 a code-coverage tool which analyzes the Pixi code against the unit-tests to see what was run and what wasn’t (uses istanbul).

Right now our current coverage is about 32%. You can view the latest report on the current dev branch. We really would like to see that number grow over time. So… we will try to improve our coverage by at least 10% for the next couple releases.

Basically, we need some help writing some tests. Here are some of the lower-hanging fruit that’s currently not being unit-tested. Here are some ideas, would gladly welcome PRs to unit-test these pieces:

Math

• Matrix
• GroupD8
• Point
• ObservablePoint

Math Shapes

• Circle
• Ellipse
• Polygon
• Rectangle
• RoundedRectangle

Loader Middleware

• bitmapFontParser
• spritesheetParser
• textureParser

GREAT NEWS was have really improved our test coverage since starting this thread it has increased nearly 10%. I’m going to close this post for now and start another thread with some new unit-testing needs. Thanks for everyone’s help. Please keep adding to our tests and submitting PRs.
