Automated tests
|
|
===============
|
|
|
|
Converse uses the `Karma <https://karma-runner.github.io/latest/index.html>`_ test runner and
|
|
`Jasmine <https://jasmine.github.io/>`_ testing library for running tests.
|
|
|
|
In addition, we use `ESlint <https://eslint.org/>`_ to run a static analysis (aka
|
|
linting) of the source files and report errors.
|
|
|
|
Whenever a commit is pushed to the Converse Github repo, all ESlint checks and
|
|
Jasmine tests are run on `Travis CI <https://travis-ci.org/github/conversejs/converse.js>`_.
|
|
|
|
Running tests
|
|
-------------
|
|
|
|
You can run ESlint by typing ``make eslint``. Similarly the tests can be run via ``make tests``.
|
|
|
|
To run both eslint and the tests, you can use ``make check``.
|
|
|
|
When running ``make test`` or ``make check``, a browser will automatically
|
|
start up, open a tab at http://localhost:9876 and start running the tests.
|
|
|
|
You'll see a green bar at the top of the page, and on the right inside it is a ``Debug`` button.
|
|
|
|
It's often helpful to click that button and run the tests in debug mode. This
|
|
way, you see better error output for failed tests.
|
|
|
|
Automatically run tests on file changes
|
|
***************************************
|
|
|
|
To automatically run the tests whenever you make a change to any of the
|
|
Converse source code, you can run ``make watch`` in one terminal, and ``make tests`` in another.
|
|
|
|
``make watch`` will build development bundles of Converse (in ``dist/converse.js`` and ``dist/converse.css``)
|
|
and automatically rebuild them whenever a source file is modified.
|
|
|
|
Similarly, Karma will make sure that the tests are re-executed when the bundle files are rebuilt.
|
|
|
|
Running individual tests
|
|
************************
|
|
|
|
Converse has over 400 tests, and it can take a while to run through all of them.
|
|
|
|
When developing on Converse, it's often preferable to have a more rapid
|
|
turnaround time between editing a file and checking whether the most relevant
|
|
tests have passed.
|
|
|
|
Jasmine tests are described by `it` functions and the tests names are written to
|
|
be read as plain English sentences that start with the word ``it``.
|
|
|
|
For example:
|
|
|
|
.. code-block:: javascript
|
|
|
|
it("is rejected if it's an unencapsulated forwarded message",
|
|
|
|
Tests are grouped by `describe` functions, and contained in spec files inside
|
|
the `spec <https://github.com/jcbrand/converse.js/blob/master/spec/>`_ directory.
|
|
|
|
To run only a single test, you can replace ``it(`` with ``fit(`` for the particular
|
|
test that you want to run. You can also do this for multiple tests. All of them
|
|
will be run whenever ``make test`` executes.
|
|
|
|
To run only a group of tests, you can similarly replace ``describe(`` with ``fdescribe``.
