Unit tests, written with [QUnit](http://docs.jquery.com/QUnit), are used to
|
||
|
|
expose bugs for squashing, prevent bugs from respawning, and suppress new
|
||
|
|
bugs when adding new features and making changes.
|
||
|
|
|
||
|
|
# Running the tests
|
||
|
|
|
||
|
|
The simplest way to run the tests is to open `tests/tests.html` in your browser.
|
||
|
|
The test suites will automatically run themselves and present their results.
|
||
|
|
|
||
|
|
To run the tests from the command line, download and install
|
||
|
|
[PhantomJS](http://phantomjs.org/), and run `run-qunit.js` with it:
|
||
|
|
|
||
|
|
$ cd tests/
|
||
|
|
$ phantomjs run-qunit.js tests.html
|
||
|
|
|
||
|
|
Failed tests and their failed assertions will be printed to the console. A
|
||
|
|
results summary will be printed at the end.
|
||
|
|
|
||
|
|
To generate coverage statistics, use [JSCoverage](http://siliconforks.com/jscoverage/)
|
||
|
|
to instrument the js files:
|
||
|
|
|
||
|
|
$ cd tests/
|
||
|
|
$ jscoverage ../js/ ../instrumented/
|
||
|
|
$ phantomjs run-qunit.js tests.html
|
||
|
|
|
||
|
|
Coverage percentage will be included in the output summary, and a highlighted
|
||
|
|
line-by-line html file will be generated.
|
||

# Shout-out
|
||
|
|
|
||
|
|
Thanks to Rod @ While One Fork for the
|
||
|
|
[CIS guide](http://whileonefork.blogspot.com/2011/10/integrating-javascript-tests-into-cli.html)
|
||
|
|
on putting the above together.

# Adding tests
|
||
|
|
|
||
|
|
Tests go in js files in the `tests/suites/` directory tree. QUnit organizes
|
||
|
|
tests into suites called "modules"; there is one module per js file. If the
|
||
|
|
tests you are adding do not fit into an existing module, create a new one at
|
||
|
|
`tests/suites/<new module>.js`, where `<new module>` is a broad yet
|
||
|
|
descriptive name for the suite. If tests have many year-specific cases (ie,
|
||
|
|
behave differently in leap years vs normal years, or have specific buggy
|
||
|
|
behavior in a certain year), create the module in a new directory,
|
||
|
|
`tests/suites/<new module>/<year>.js`, where `<new module>` is the decriptive
|
||
|
|
name and `<year>` is the four-digit year the tests pertain to.
|
||
|
|
|
||
|
|
In order for new tests to be run, they must be imported into `tests/tests.html`.
|
||
|
|
Find the script includes headed by the html comment `<!-- Test suites -->`, and
|
||
|
|
add a new one to the list which includes the new js files.
|
||

# Can I use this?
|
||
|
|
|
||
|
|
By all means, please do! Just note that I stopped working on this structure
|
||
|
|
once it fit my needs, there's no real support for it, and it may change in the
|
||
|
|
future. Otherwise, have at it.
