It has been detected, thanks to php80 specially, that there are
various places in core where support for localised floats is
missing. Before php80, some locale-dependent conversions were
performed by PHP, allowing things to work. But with php80 all
those comparisons are now locale-independent. See:
https://wiki.php.net/rfc/locale_independent_float_to_string
That implies that we now need to, always, unformat floats to
be internally the correct (decimal point as separator) in
order to compare it.
While this was visited in the php80 epic (MDL-70745), nothing
was found, all automated tests were passing ok. Problem is that
we run behat tests with en-AU laguage that has the decimal point
separator.
So, in this issue we are fixing all the problems detected by
running those Behat tests using localised (comma) decimal
separator.
Note that there may be other places still causing problems, but
it's really hard to find them programmatically, so we'll have to
wait for real use reports / issues and go fixing them while they
happen.
Back to this commit, this is the list of changes performed (note that
in the next commit, we'll be adding scenarios explicitly using
a localised decimal separator to ensure that they work ok).
A. Changes to various grade forms to ensure that, on their validation
floats are unformatted properly. Also, changed the corresponding
form element from current text/PARAM_RAW to proper float ones that
take care of the conversion in a number of places (but when disabled,
that's the reason we still have to unformat in validation.
This includes the following forms:
- edit_category_form
- edit_item_form
(this is the original problem reported that cause all the research
to be performed against full behat runs)
B. Changes to edit_letter_form, so it uses a proper PARAM_LOCALISEDFLOAT
(note this is the type of change that surely should be used for all
the rest of /grade/edit/tree form, including those in the previous
point).
C. Changes to the grade_item behat generator, so it's able to work with
localised floats, un-formatting them when needed.
At lib/behat/classes/behat_core_generator.php
D. Fix problem passing localised floats to scales, not displaying
properly. At grade/report/singleview/classes/local/ui/finalgrade.php
E. Change the behat text matcher in order to allow comparison of
localised floats when they are the current ones. Before this change
the matches was using soft/lazy comparison, so '50' and '50.0000'
match. Now, when the comma (for example) is used (and only then),
'50' and '50,000' will also match. This comparison is in use in a
bunch of tests and makes sense to make it localisation-aware.
At grade/report/singleview/classes/local/ui/finalgrade.php
F. Fix a couple of number_format() uses in lesson, because they are
not localised-aware. Switched to format_float(). At mod/lesson/locallib.php
G. Change the quiz_contains_the_following_questions() step to accept
localised maxmark expectations. At mod/quiz/tests/behat/behat_mod_quiz.php
H. Change the quiz generator so it accepts localised gradepass.
At mod/quiz/tests/generator/lib.php
I. Change the edit question form to show proper localised penalties,
previously it was always showing point-decimal ones. Of course,
leaving the values of the select element unmodified (internal floats).
Related, also change a couple of tests to, instead of try to match the
value (always internal floats), match the description (now localised),
so we can test them with different separators. At:
- question/type/ddimageortext/tests/behat/backup_and_restore.feature
- question/type/ddmarker/tests/behat/backup_and_restore.feature
- question/type/edit_question_form.php
In some situations it is useful to modify the requested screensize by a
modifier. This allows for failing tests to be rerun at a different
screensize, where the original screensize triggered a failure for some
size-related reason.
This commit makes the following improvements to core page resolverss:
* allows for mixed case naming (course, Course, etc.)
* allows fields other than the idnumber to be specified:
** course: idnumber, shortname, fullname
** course category: idnumber, name
Whilst some of these fields are not unique, they will typically be
unique in most test scenarios. Where they are not then the idnumber
should be used in preference.
The activity generator currently requires an idnumber when creating
activities, but this is not a requirement when creating the same
activity through the UI. The requirement comes because we want to
provide a way to refer to activities in subsequent steps.
This commit modifies the behaviour such that the generator uses the name
of the activity as the default idnumber.
This has two main benefits:
1. it simplfies generation of activities; and
2. it makes the language used when writing behat tests much more natural.
With this change, steps will refer to the activity by its idnumber/title
in all cases, rather than sometimes by an idnumber which bears no
relevance to the title.
This change introduces a new function to execute Javascript directly on
a node.
This should not, ordinarily, be used directly by steps, but may be
required in other parts of the Behat interaction.
The PHP WebDriver Mink Driver does not necessarily require Selenium. It
supports Selenium 3 upwards, and can be used directly with ChromeDriver,
EdgeDriver, SafariDriver, GeckoDriver, and others.
It therefore uses a slightly different configuraitno path.
This commit updates core Behat features to make use of the
php-webdriver/webdriver library instead of the legacy Instaclick
library.
Most of these changes relate to use of features of WebDriver which we
are required to use directly rather than through the Mink Driver.
