Why this change?
As the number of themes which the Discourse team supports officially
grows, we want to ensure that changes made to Discourse core do not
break the plugins. As such, we are adding a step to our Github actions
test job to run the QUnit tests for all official themes.
What does this change do?
This change adds a new job to our tests Github actions workflow to run the QUnit
tests for all official plugins. This is achieved with the following
changes:
1. Update `testem.js` to rely on the `THEME_TEST_PAGES` env variable to set the
`test_page` option when running theme QUnit tests with testem. The
`test_page` option [allows an array to be specified](https://github.com/testem/testem#multiple-test-pages) such that tests for
multiple pages can be run at the same time. We are relying on a ENV variable
because the `testem` CLI does not support passing a list of pages
to the `--test_page` option.
2. Support a `/testem-theme-qunit/:testem_id/theme-qunit` Rails route in the development environment. This
is done because testem prefixes the path with a unique ID to the configured `test_page` URL.
This is problematic for us because we proxy all testem requests to the
Rails server and testem's proxy configuration option does not allow us
to easily rewrite the URL to remove the prefix. Therefore, we configure a proxy in testem to prefix `theme-qunit` requests with
`/testem-theme-qunit` which can then be easily identified by the Rails server and routed accordingly.
3. Update `qunit:test` to support a `THEME_IDS` environment variable
which will allow it to run QUnit tests for multiple themes at the
same time.
4. Support `bin/rake themes:qunit[ids,"<theme_id>|<theme_id>"]` to run
the QUnit tests for multiple themes at the same time.
5. Adds a `themes:qunit_all_official` Rake task which runs the QUnit
tests for all the official themes.
Why this change?
As the number of themes which the Discourse team supports officially
grows, we want to ensure that changes made to Discourse core do not
break the plugins. As such, we are adding a step to our Github actions
test job to run the system tests for all official themes.
What does this change do?
This change adds a step to our Github actions test job to run the system
tests for all official plugins. This is achieved by the introduction of
the `themes:install_all_official` Rake task which installs all the
themes that are officially supported by the Discourse team.
Using restore-keys means we will always use an old cache, and then add more dependencies to it. This leads to the cache growing over time and becoming increasingly slow. Instead, we should rebuild the cache from scratch each time our dependencies change.
Without this change the resulting comparison looks like
```
if [ tests-passed == "tests-passed" ]; then
```
and so it was always failing. This way the resulting base branch name will also be in quotes for the comparison.

* DEV: Adds a GitHub workflow to check target branch
Adds a GitHub workflow to check that the target branch for PRs in the
discourse-private-mirror repo aren't set to the tests-passed branch.
* Rename workflow
This fixes a similar issue to 8b3eca0 where an Errno::ETXTBSY error was raised because the minio_runner gem was trying to install the binary across multiple processes in rspec. If we just make sure the latest version is installed before the tests run, this shouldn't happen, since MinioRunner.start will not do any further attempts at installation if the latest version is installed.
This workflow runs only for code underneath the `migrations/` directory. The usual test workflow is skipped for migrations because running frontend and backend tests is a waste of time and resources when only migrations are changed.
Discourse core now builds and runs with Embroider! This commit adds
the Embroider-based build pipeline (`USE_EMBROIDER=1`) and start
testing it on CI.
The new pipeline uses Embroider's compat mode + webpack bundler to
build discourse code, and leave everything else (admin, wizard,
markdown-it, plugins, etc) exactly the same using the existing
Broccoli-based build as external bundles (<script> tags), passed
to the build as `extraPublicTress` (which just means they get
placed in the `/public` folder).
At runtime, these "external" bundles are glued back together with
`loader.js`. Specifically, the external bundles are compiled as
AMD modules (just as they were before) and registered with the
global `loader.js` instance. They expect their `import`s (outside
of whatever is included in the bundle) to be already available in
the `loader.js` runtime registry.
In the classic build, _every_ module gets compiled into AMD and
gets added to the `loader.js` runtime registry. In Embroider,
the goal is to do this as little as possible, to give the bundler
more flexibility to optimize modules, or omit them entirely if it
is confident that the module is unused (i.e. tree-shaking).
Even in the most compatible mode, there are cases where Embroider
is confident enough to omit modules in the runtime `loader.js`
registry (notably, "auto-imported" non-addon NPM packages). So we
have to be mindful of that an manage those dependencies ourselves,
as seen in #22703.
In the longer term, we will look into using modern features (such
as `import()`) to express these inter-dependencies.
This will only be behind a flag for a short period of time while we
perform some final testing. Within the next few weeks, we intend
to enable by default and remove the flag.

This commit adds some system specs to test uploads with
direct to S3 single and multipart uploads via uppy. This
is done with minio as a local S3 replacement. We are doing
this to catch regressions when uppy dependencies need to
be upgraded or we change uppy upload code, since before
this there was no way to know outside manual testing whether
these changes would cause regressions.
Minio's server lifecycle and the installed binaries are managed
by the https://github.com/discourse/minio_runner gem, though the
binaries are already installed on the discourse_test image we run
GitHub CI from.
These tests will only run in CI unless you specifically use the
CI=1 or RUN_S3_SYSTEM_SPECS=1 env vars.

We can no long user Webdriver - SeleniumHQ/selenium#11066. Bumping selenium-webdriver did the trick, as well as manually setting the user_agent for mobile system specs. Unsure what changed to make this necessary, but it is necessary to get the app to boot in mobile view.
Why this change?
This is abit of a trial and error but we're starting to see selenium
session not created errors on CI. One of the reason for this is that the
system has run out of resources to create a new tab.
This commit reduces the number of parallel test processors in an attempt
to increase the amount of resources available to each test process and
hopefully lead to more stable CI system tests.
This reverts commit 865f7a9852.
The flakiness that we have been seeing and fixing on CI were not related
to system resource problems. Therefore, we can bump this up back to 5.
Why is this change required?
We've been seeing flaky tests due to server errors on CI but are unable
to debug it because we do not log any of the errors. This change gives
us a fighting chance the next time we encounter a server error during
system test runs.
See
https://github.com/discourse/discourse/actions/runs/5459248864/jobs/9935049920?pr=22424
for an example of server errors encountered during system tests.
Using the runtime information, we will be able to more efficiently group
the test files across the test processes hence leading to better
utilization of resources.

4dd053a69c addressed most of the
instability we were seeing with system tests on CI and locally. Let's
try pushing the number of parallel processes up to squeeze as much time
savings as possible from the runner.
We're running on pretty crappy hardware on Github's CI and this has an
impact on the stability of our system tests on CI. Therefore, we are
bumping `CABPYARA_DEFAULT_MAX_WAIT_TIME` to 10 seconds to account for
the less than ideal hardware we're running the system tests on.
This change trades off speed for stability but speed is already bad on
CI so stability is more important for our case.
