This is preparation for our migration of our JS pipeline to webpack,
which includes as part of the process a hack of exporting globals via
the window object.
We have less urgency to test all templates now. The
most common error is probably unbalanced tags, and our
python-based template checker catches those problems
pretty well.
It's still possible to create bad templates, of course,
but the node tests have never been super deep at finding
semantic errors.
This run_test helper sets up a convention that allows
us to give really short tracebacks for errors, and
eventually we can have more control over running
individual tests. (The latter goal has some
complications, since we often intentionally leak
setup in tests.)
I don't think anybody ever really used this feature, which I
developed but don't even use myself. It kind of runs counter
to the minimalist approach of the rest of node tests.
I would eventually like to re-think the template tests altogether.
They're slow, and we could solve that somewhat by replacing
jsdon/jquery with an HTML parser library to verify structural
things.
It's also possible that we can just rely on our template linters
to catch the biggest class of errors (malformed tags) and let
code review do the rest.
And it's also possible that we should make a second attempt to
ramp up tooling on making it easy to verify templates, but it
doesn't have to be part of the node tests. If we did that, we
would also potentially use tooling for Python-side templates.
We are phasing out the following in tests:
add_dependencies - this is just kind of a clunky UI
require - normal JS requires cause test leaks
In order to plug require leaks, we are effectively doing what
we always have done inside of add_dependencies, which is to
keep track of which modules we have done `require` on, and
these get cleared between tests.
Now we just use `zrequire` every time we want to pull in real
code to our global namespace.
This allow the webbpack dev server to properly reload JavaScript modules
while running in dev without restarting the server. We need to connect
to webpack-dev-server directly because SockJS doesn't support more than
one connection on the same host/port.
The function with_overrides() uses the logic from the old
run() function in dispatch.js to allow you to call a test
function and override parts of the global namespace only
for the duration of when test_function runs.
- Remove `underscore.js` from `static/third` and fetch it from `npm`.
- Upgrade `underscore.js` to 1.8.3.
- Bump up the `PROVISION_VERSION` to 4.2.
Part of #1709
- Remove `codepointat` from `static/third` and fetch it from `npm`.
- Upgrade `codepointat` to 0.2.0.
- Bump up the `PROVISION_VERSION` to 4.1.
Part of #1709.
Now we just have two methods of importance:
compile_template
render_template
The compile_template() function will automatically
(and recursively) compile any partials it depends
on and mark those as compiled.
When the render function is run now, it uses the partial_finder
function to search recursively through files for partials and add them
so that test writers don’t have to.
This means that we no longer have to do any manual work to maintain
the templates.js check that all handlebars templates are rendered by
the node tests.
This makes sure we are explicit about partials in
individual test modules. Eventually, we should figure
out a way to make partials automatically compile as
part of the node tests.
This introduces a very minor different in behavior if you specify
an invalid filename as a command line argument. We now show
warnings for those *before* running the rest of the tests.
