This is consistent with Jest and other standard test runners, and is
necessary to support asynchronous tests.

The stream list left sidebar currently has 3 sections:
* Pinned (+ Muted pinned streams)
* Active (+ Muted active streams)
* Inactive streams
Previously, these sections were separated by horizontal lines, which
did not provide an easy way to discern why there were sections. We add
labels to these section dividers to help with this.
Additionally, within each section, we now sort all muted streams to
the bottom, so that they general minimal clutter.
Fixes#19812.
When we were preparing the conversion to ES modules in 2019, the
primary obstacle was that the Node tests extensively relied on the
ability to reach into modules and mutate their CommonJS exports in
order to mock things. ES module bindings are not mutable, so in
commit 173c9cee42 we added
babel-plugin-rewire-ts as a kludgy transpilation-based workaround for
this to unblock the conversion.
However, babel-plugin-rewire-ts is slow, buggy, nonstandard,
confusing, and unmaintained. It’s incompatible with running our ES
modules as native ES modules, and prevents us from taking advantage of
modern tools for ES modules. So we want to excise all use of
__Rewire__ (and the disallow_rewire, override_rewire helper functions
that rely on it) from the tests and remove babel-plugin-rewire-ts.
Commits 64abdc199e and
e17ba5260a (#20730) prepared for this by
letting us see where __Rewire__ is being used. Now we go through and
remove most of the uses that are easy to remove without modifying the
production code at all.

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.
The series of commits to consolidate CSS classes
for the various unread-count spans across our app
created a bug where the stream_list.js code's selector
starting capturing the unread spans in topic list items.
Suppose you had a stream with these topics:
Foo 10
a 3
b 3
c 4
If another unread came in, you would briefly see:
Foo 11
a 11
b 11
c 11
Now we just use subscription_block to find the
element that we want to tweak.
I remove a convoluted node test here. Part of the
reason the node test was convoluted was that the
original implementation was overly complex. I will
try to re-introduce a simpler test soon, but this
is a bit of an emergency fix.
In an effort to use a common class to display unread counts across
the app, we simplify the elements used to show unreads and use a
single `span` with `unread_count` class to do so.
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

We now call $.clear_all_elements at the top
of run_test.
We have to exempt two modules from the new regime:
compose
settings_user_groups
Also, if modules do set_global("$", ...) we don't
try to call the non-existent function.
It's possible we'll want to move to something like
this, but we might want to clean up the two
sloppy_$ modules first:
// AVOID THIS:
// const $ = require("zjquery")
run_test("test widget", ({override, $}) => {
override(foo, "bar", ...);
$.create(...);
// do stuff
});
We no longer export make_zjquery().
We now instead have a singleton zjquery instance
that we attach to global.$ 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");
