GCLI has a test suite that can be run in a number of different environments. Some of the tests don't work in all environments. These should be automatically skipped when not applicable.
Running a limited set of test from the web is the easiest. Simply load 'localtest.html' and the unit tests should be run automatically, with results displayed on the console. Tests can be re-run using the 'test' command.
It also creates a function 'testCommands()' to be run at a JS prompt, which enables the test commands for debugging purposes.
GCLI's test suite integrates with Mochitest and runs automatically on each test run. Dryice packages the tests to format them for the Firefox build system.
For more information about running Mochitest on Firefox (including GCLI) see the MDN, Mochitest docs
Running the test suite under node can be done as follows:
$ node gcli.js test
Or, using the test command:
$ node gcli.js
Serving GCLI to http://localhost:9999/
This is also a limited GCLI prompt.
Type 'help' for a list of commands, CTRL+C twice to exit:
: test
testCli: Pass (funcs=9, checks=208)
testCompletion: Pass (funcs=1, checks=139)
testExec: Pass (funcs=1, checks=133)
testHistory: Pass (funcs=3, checks=13)
....
Summary: Pass (951 checks)
The GCLI test suite can also be run under PhantomJS as follows:
$ phantomjs ./phantom-test.js
Summary: Pass (4289 checks)
Finished running unit tests. (total 3.843s, ave response time 3.36ms, ...)
GCLI check-ins are automatically tested by Travis CI.
GCLI can generate test cases automagically. Load localtest.html, type a
command to be tested into GCLI, and the press F2. GCLI will output to the
console a template test case for the entered command.
