Build Status

This is the core library for uijs. It contains the low-level rendering and binding engines and some utilities.

To get started with uijs, see the uijs README.

See organization for some info on what's here and what's elsewhere.

Tests

To run visual tests, you will have to install cairo. On a mac with homebrew just type brew install cairo.

npm test will run all tests. These are the regression tests that should be executed before commiting code into the repository.

We have two types of tests:

  1. Functional tests are located under test/*.test.js. Functional tests are simply node.js scripts. If they exit with a non zero exit code, the test failed.
  2. Visual tests are located under test/*.cantest.{js|png}. Visual tests use node-canvas and cantest and can be executed using cantest xxx.cantest.js. Read more about visual tests in the cantest README file.

Running all tests:

$ npm test
> uijs@0.0.1 test
> cd test && ./run.sh

Benchmarks

Benchmarks are uijs apps (export a box). All benchmarks are under the benchmarks directory. To run a benchmark, use the uijs devtool bench or prof commands. By default the benchmark will run for 5 seconds. If prof is used, it will show a profiler output.

$ cd benchmarks
$ uijs bench the-box.js
the-box.js 34303.2fps
$ uijs prof the-box.js
...
... # benchmark results
...
the-box.js 36176.4fps

Note that since benchmarks are regular uijs apps, they can usually be also opened from the browser. The fps measurements will be outputed to the console.

$ cd benchmarks
$ uijs debug the-jumping-box.js
http://localhost:5000

Results
