We now only expose mock_template as a helper in run_test.
This has the following advantages:
* less boilerplate at the top of the file
* more surgical control with setting exercise_templates
* no more "f" hack (or render_foo consts)
* we force devs to explicitly mock the template
See frontend_tests/zjsunit for the substantive changes.
All the changes to the tests are very mechanical in nature.
We use css() pretty rarely in our codebase, and
it can sometimes be used mistakenly, when a better
alternative is to toggle a class for external css.
It's hard to support the full API in zjquery, so
we just punt and tell folks to create their own
stubs.
Most of the existing tests that were "fixed" here
weren't actually verifying the behavior of the css()
calls, and for those I just create no-op stubs.
In a few places I verify that css() was called as
expected.
Previously, the hook to save drafts when closing the compose box was a
focusout on #compose-textarea. This mostly worked, and was essentially
invisible to users (because the animation to notify you about saved
drafts was in the close_compose_ui widget that is hidden), but you'd
end up seeing the tooltip appear (in the wrong place) if you closed
the compose box immediately after sending a message with Tab+Enter.
The correct fix is for the drafts hook to be just before we start
clearing compose box state, inside hide_box.
This was difficult to catch in a development environment, since one
doesn't use that flow with "Enter sends" enabled.
Use fully resolvable request paths because we need to be able to refer
to third party modules, and to increase uniformity and explicitness.

For most functions that we were using __Rewire__ for,
it's better to just use the override helper, which
use __Rewire__ under the hood, but also resets
the reference at the end of run_tests.
Another nice thing about override() is that it reports
when you never actually needed the mock, and this
commit fixes the instances found here.
I didn't replace every call to __Rewire__. The
remaining ones fall under these categories:
* I looked for ") =>" in my code sweep,
so I missed stuff like "noop" helpers.
* Sometimes we directly update something
in a module that's not a function. This
is generally evil, and we should use setters.
* Some tests have setup() helpers or similar
that complicated this code sweep, so I
simply punted.
* Somes modules rely on intra-test leaks. We
should fix those, but I just punted for the
main code sweep.
We now just use a module._load hook to inject
stubs into our code.
For conversion purposes I temporarily maintain
the API of rewiremock, apart from the enable/disable
pieces, but I will make a better wrapper in an
upcoming commit.
We can detect when rewiremock is called after
zrequire now, and I fix all the violations in
this commit, mostly by using override.
We can also detect when a mock is needlessly
created, and I fix all the violations in this
commit.
The one minor nuisance that this commit introduces
is that you can only stub out modules in the Zulip
source tree, which is now static/js. This should
not really be a problem--there are usually better
techniques to deal with third party depenencies.
In the prior commit I show a typical workaround,
which is to create a one-line wrapper in your
test code. It's often the case that you can simply
use override(), as well.
In passing I kill off `reset_modules`, and I
eliminated the second argument to zrequire,
which dates back to pre-es6 days.
Found by running the tests after
sed -i 's/\.with(/.toBeUsed().with(/g' frontend_tests/node_tests/*.js

Callers can either explicitly pass in children,
stub out $(...)[0] as needed, or just
circumvent jQuery complications with override.
Note the reactions test was broken before,
since $(...)[0] was always returning the same
stub.
We no longer export make_zjquery().
We now instead have a singleton zjquery instance
that we attach to global.$ in index.js.
We call $.clear_all_elements() before each module.
(We will soon get even more aggressive about doing
it in run_test.)
Test functions can still override $ with set_global.
A good example of this is copy_and_paste using the
real jquery module.
We no longer exempt $ as a global variable, so
test modules that use the zjquery $ need to do:
const $ = require("../zjsunit/zjquery");
This splits the one big `run_test` block into
add/edit/delete parts, for better clarity.
This also removes the `with_field` calls and
uses the override style instead, which is
preferred because it makes sure the stubbed
function is actually called.
We still need to write to these globals with set_global because the
code being tested reads from them, but the tests themselves should
never need to read from them.

I have a local branch with a hacked up version of
zjquery that lets you basically detect when zjquery
stubs are never actually invoked by real code.
There are some nuances to that kind of audit, so
I haven't pushed the auditing code, but these
are low hanging fruit.
ES and TypeScript modules are strict by default and don’t need this
directive. ESLint will remind us to add it to new CommonJS files and
remove it from ES and TypeScript modules.
