With chromedriver >= 80, the tests are freezing sometimes, particularly
when the same editor is loaded again.
We don't know whether it's a CKEditor issue or a chromedriver issue. In
the past we've had some errors related to CKEditor trying to load the
same instance twice and we aren't sure they have been fixed since we
could never reproduce them.
It could be a coincidence, though. If we modify the views so the only
content of the `<body>` tag is a textarea with the `html-area` class,
chromedriver freezes even if we only access the page once. So maybe
we're only detecting the problem on the second visit because the second
request is faster than the first one.
Since chromedriver no longer hangs after this change, we don't have to
force any chromedriver version anymore.
After upgrading to chromedriver 80, tests checking CKEditor's content
were causing chromedriver to hang. That's why we were configuring
webdrivers to use an older chromedriver.
Version 80 of chromedriver introduced several issues regarding frames.
Debugging shows in this case chromedriver froze when we used `setData`
and then `within_frame`. Since adding a `sleep` call made it work, we
think `within_frame` was being executed before `setData` had finished.
The fact that `setData` causes the browser to enter the frame having
CKEditor is probably the reason.
Even though the `setData` method provides a callback when it's finished,
configuring it so the rest of the Ruby code isn't executed until that
happens leads to complex code. Using Capybara's `set` to fill in the
editor is IMHO a bit easier to understand.
After this change, since we're using a method provided by Capybara
instead of executing asynchronous JavaScript code, we don't have to
check CKEditor has been filled anymore. The "Admin Active polls add"
test, which failed on my machine without that check, now passes.
If we don't use the `exact` option, tests will pass even if filling in
CKEditor adds the content twice or adds the new content to the existing
content, which has actually happened and has gone mostly unnoticed while
testing several ways to fill in CKEditor with Capybara (particularly,
when using Capybara's `send_keys` method). The problem was detected by
just one test, which checked the original content wasn't present anymore
after updating a record.
When a user replies to a comment whose responses was hidden at the
moment of reply form submission and although the reply were correctly
added to the DOM it was hidden because was added to a collapsed list.
This solution is about showing all responses of parent comment after adding
the new comment to the DOM so the user can see new reply into the screen.
(This is not applicable to root comments which cannot be collapsed)
Extract the needed portion of code to a new partial to be able to update
only the elements needed when a new comment is added keeping UI properly
updated.
In this case the confirmation dialog isn't really necessary since the
action to enable/disable the setting can easily be undone.
Furthermore, these tests were failing with Chrome 83, probably because
we use `confirm_dialog` and then we use `visit` without checking the
page in between.
In theory we shouldn't need to check the page in between because the
request generated by `confirm_dialog` is a synchronous one and so
`visit` isn't executed after the previous request has finished, but
apparently this behavior has changed in Chrome 83.
We could add an expectation before executing the `visit` method, but
that wouldn't improve the usability of the application.
The latest stable version is causing problems on some machines, hanging
forever in tests involving frames. So we're installing an old version
which works with the latest Chrome.
Note this means we're using an unsupported version. Officially, only the
latest chromedriver supports the latest Chrome.
We're using 2.38 instead of a more recent one (like 2.40) because it's
the one we specified in our Dockerfile.

The number of errors in a form includes several errors for the same
field. For example, if a title is mandatory and has to have at least 5
characters, leaving the title blank will result in two errors. So users
will be invited to look for two errors, but they'll only find one field
with errors.
So it's a bit more intuitive to show as many errors as fields having
errors.
Note we're excluding errors on `:base`, which is a bit of a hack for
errors in association fields. For example, if the title of one
translation is not present, `resource.errors.messages` will contain two
elements: one for the translation's title, and one for the `base` field.
This resulted in the count of errors being 2 when there was only one.
Also note I haven't found a way to count errors on all `has_many`
relations. That is, if two translations have a missing title field, only
one error will be mentioned in the message (as it did before this
commit).
We were submitting the form without checking the AJAX request to attach
the image had finished, so sometimes two requests were executed at the
same time. Sometimes this made InvisibleCaptcha to go crazy and report
the form was submitted too quickly.
Checking the first AJAX request has finished before submitting the form
solves the problem.
We were checking `expect_document_has_title(0, "My Title")`, which was
already true before the AJAX request generated by `attach_file` had
finished.
That meant the AJAX request sometimes was handled after this test had
finished, affecting the following test and causing it to fail because
its cookie was overwritten and so `current_user` was set to `nil`.
In the test checking the filename is present, a similar scenario was
taking place: we were updating the `.file-name` element in the `change`
event of `fileupload` (using `App.Documentable.setFilename`); that is,
when the AJAX request started. And so the test passed before the request
was finished, causing the same issue.
We were using a <ul> tag for a single comment, where the first element
of the list was the comment itself and the second element was the list
of replies.
IMHO it makes more sense to have a list of all comments, where every
element is a comment and inside it there's a list of replies.
We're also rendering the list even if it has no children so it's easier
to add comments through JavaScript. Then we use the :empty CSS selector
to hide the list if it's empty. However, since ERB adds whitespace if we
structure our code the usual way and current browsers don't recognize
elements with whitespace as empty, we have to use the `tag` helper so no
whitespace is added.
Tests are also a bit easier to read, even though we need to use the
`text:` option to find links because otherwise the text in the hidden
`<span>` tags will cause `click_link` to miss the link we want to click.
Here's an explanation by one of Capybara's authors:

When a page with ckeditor is restored from browser cache by using browser
history back feature application was trying to re-initialize it but this was
throwing some javascript errors that left ckeditor useless. The ckeditor user
interface seemed to be loaded correctly but editor contents was not shown
and ckeditor locked.
This solution is about destroying all ckeditor instances on page before
leaving it and force the reinitialization after Turbolinks restored the cache.
Inspiration here [1].
There is a similar patch to make it work with Turbolinks 5.x versions [2].

We were calling initialize_modules after every ajax call only to apply the
application javascript to new elements added though ajax calls, this is not
always needed because some ajax calls do not add new elements to the user
interface so there is no new elements to initialize. This technique was working
fine in most cases but was causing different kind of problems at some pages where
some elements where being unnecessarily reinitiliazed causing the execution of the
element associated scripts as many times as the element was initialized. This fix
should relief a little bit of work to users browsers.
After this change we had to fix some pieces of javascript:
Regarding LegistationAnnotatable module, since we are not re-initializing Annotator
app we cannot destroy it so now we only need to insert the new annotation into annotator
interface to keep it properly updated.
Regarding Comments module, we do not need anymore the initialization check because this
code only will be fired once now we do not launch application initialization after ajax
calls. Also, when a new comment is created its added to the DOM through AJAX and include
some elements that needs javascript initialization to work. By using
"Delegated event handlers" [1] new comments will be initialized automatically when added.

The method `available_locales` in
`RemoteTranslations::Microsoft::AvailableLocales` needs to execute a
request to an external server in order to work, meaning it will fail if
the machine its executed on doesn't have an internet connection.
So we're stubbing the method in the tests using it.
We were evaluating its value when the server starts. On production
enviroments, that could mean weeks or months before the available
locales are checked again, and so it would be possible to use a list
which is no longer in sync with the list provided by microsoft.
I incorrectly used "text" as variable name in commit 2cdc6a1b. In
similar places, we use `label`. We also use named parameters when only
`with:` is provided.
Some specs involving CKEditor were failing sometimes in the Rails 5.1
branch. The reason why these specs pass with Rails 5.0 but fail with
Rails 5.1 are unknown. On my machine the tests pass when precompiling
the assets, which makes me think it's related to the way Rails handles
them, but it might have nothing to do with it.
The only (apparently) 100% reliable solution I've found is to wait for
CKEditor to load before trying to fill it in. After running the tests on
my machine hundreds of time, I didn't get a single failure.
Using `render :nothing` was deprecated, but we never noticed it because
we didn't have a test for the action using it. In Rails 5.1, it raises
an exception.
Using `head :ok` and adding a test for this scenario solves the issue.
CKEditor repositions the dialog to attach an image after showing it. If
its position changes right when Capybara is trying to click the "Upload"
link, the click does not work properly.
I haven't found a way to check the dialog has stopped moving, so I've
chosen to force its position to the top.
Without this change, this test failed a lot on my machine when using
Rails 5.1, both with an "iframe ckeditor" and an "inline ckeditor".
However, it didn't fail when using Rails 5.0.
Since we use transactions now for every test, we can seed the database
at the beginning, and then it will go back to this state before a test
is executed.
Running the test suite is now considerably faster. On my machine, we
save a quarter of second per system test, meaning we save several
minutes for the whole suite.
We were manually setting `http://www.example.com`. However, Capybara now
uses `http://127.0.0.1`.
While we could change the code to use `127.0.0.1`, I think directly
using `Capybara.app_host` makes it easier to realize what the code is
doing. And, particularly, now it's clear the host has nothing to do with
our `Setting["url"]`, which by default points to `www.example.com` as
well.
This method is deprecated in Rails 5.1 because its behavior will be
different in `before` and `after` callbacks.
We're replacing the deprecated `attribute_changed?` and `attribute_was`
methods with `saved_change_to_attribute?` and
`attribute_before_last_save` during `after_save` callbacks.
https://github.com/rails/rails/pull/32835/
Rails 5.1 introduced certain changes in the way a record is touched when
the counter cache option is enabled in a belongs to association.
We need to upgrade acts-as-taggable-on so it keeps changing the
`updated_at` attribute when a new tag is added to a record.
Note we now need to reload the records in some cases to get the
`context_tag_list` method to return what we expect. Methods like
`context_tags` however work properly with no need to reload the record.
This feature was not working so its better to disable it completely.
By removing attachment_files endpoints related buttons and tabs from ckeditor UI are not shown to users anymore.
We were getting a warning: "Checking for expected text of nil is
confusing and/or pointless since it will always match. Please specify a
string or regexp instead" because we were checking for values which were
set to `nil` in the tests.
Since we're only doing the convertion from bytes to megabytes in one
place, IMHO adding an extra method makes the code harder to read.
This way we don't have do include the DocumentsHelper in the specs
anymore, reducing the risk of possible method naming collisions.
Including them might lead to conflicts since two methods might have the
same name. For example, we're getting some exceptions when taking
screenshots of a failing test, because the method `image_path` from
`ActionView::Helpers::AssetUrlHelper` has the same name as a method used
to save the screenshot.
Besides, we were including all helpers in places were only the `dom_id`
method is used, and in other places where no helper methods were used at
all. So we can just invoke `ActionView::RecordIdentifier.dom_id`
directly.
Implementation tries to be open for further extensions, such as deciding on
search dictionary based on configuration option or by locale set for
given user.
The method `tag_list_on` doesn't add an `ORDER_BY` clause to the SQL
query it generates, and so results may come in any order.
However, in the tests we were assuming the tags were ordered by ID in
descending order. Since that isn't always the case, the tests were
failing sometimes.
Ordering the tags alphabetically solves the problem. We could also use
the same order admins used when adding the tags:
```
@process.customs.order("taggings.created_at").pluck(:name).join(", ")
```
However, I'm not sure it improves the user experience, and it makes the
code more complicated.
benefit to administratos.
It looks like sometimes, particularly when the first thing we do after
loading a page is filling the CKEditor fields and submitting the form,
CKEditor doesn't have enough time to format the text, and so it's sent
as plain text instead of HTML. This behaviour can be reproduced on my
local machine after upgrading to Rails 5.1, with the test "Admin Active
polls Add" failing 100% of the time.
Checking CKEditor has been filled in correctly solves the issue.
When an investment had been assigned a user tag and a valuation tag with
the same name, it appeared twice when filtering by tag.
This is because by design, in order to provide compatibility with scopes
using "select" or "distinct", the method `tagged_with` doesn't select
unique records.
Forcing the query to return unique records solves the issue.
