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.

This increases consistency and saves a bit of code, but more
importantly, it makes it much easier to switch between these APIs
while refactoring tests.

We change the generic message copy while we're at it.
Also, show login_to_access modal when a spectator tries to access
a stream that either does not exist is is not web-public.
It's 2022 and the WHATWG no longer recognizes the term URI. Everything
is now a URL or a type of URL. Which is great because it's way less
confusing. Details here:
https://url.spec.whatwg.org/
Removed existing empty narrow divs from app/home.html and created
a new javascript module to dynamically load empty narrow messages
using handlebar template.
Fixes#18797
This shortcut now renarrows to an empty topic, rather than to the
stream, as long as the topic input is nonempty.
This was debated in the original implementation of this feature:
https://github.com/zulip/zulip/pull/9511#discussion_r190323319
Having seen the experience in practice, the current behavior is
surprising and we should migrate to the other option originally
considered. In particular, the argument that "narrowing to the stream
would still tell you the topic is empty" turns out to be inaccurate,
since the history within the stream may not be in the most recent
messages in the stream.
Fixes#19122.
The default label for empty narrows depends on whether it's a
stream/topic narrow or a PMs narrow.
We leave some default text in compose.hbs for reply label
because it take some time for the js to display the
correct label.
This is mostly a pure code move.
In passing I remove an unneeded call to
update_calculated_fields in the dispatch code,
plus some tests that don't need them.
Previously we were liable to have false positives in our tests here
because we did not reset the visible state for these selectors, this
commit adds a helper and relevant calls to it in order to prevent such
false positives.
This is a mostly verbatim extraction.
I re-phrased one line of code to work around a lint
false alarm. (Look for `preamble` in the diff.)
There are about 8 lines missing coverage here, so
the new module might be a good candidate to get
100% line coverage on.
Before this change, you would need to remove 74
edges from our dependency graph to make it
acyclic. Now it's 72.
Use fully resolvable request paths because we need to be able to refer
to third party modules, and to increase uniformity and explicitness.

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 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");
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.
