After we upgraded to QUnit 1.23.1, we gained support for
assert.expect(). This allows us to guard against any race conditions
within tests, because now expect() will be linked to the specific test
instead of the current running test.
These tests did not cover the classes that should have been
automatically applied to the dropdown based on the space around it. Now
they both test that the dropdown should be facing down, because there is
enough space below it to display the dropdown.
This fixes the two failing assertions that only triggered in IE 9 (no
other versions) and Firefox. Both of them were caused by the offset for
the dropdown including a constant extra amount, what appeared to be
related to the size of the container if it actually had content. This
was not consistent in browsers, so now we are forcing there to be a
small amount of content within the container and then calculating the
expected offset based on that height.
There was a commit that landed in 4.0.1 that fixed positioning for
non-static elements, which are commonly used for the custom
`dropdownParent` option, but broke positioning for statically positioned
elements, commonly used in almost every other case. That commit was
c9216b4b96
This fixes the positioning issues caused by that commit by properly
calculating the offsets for statically positioned parents. Statically
positioned parents are unique, because the offset for the dropdown must
be calculated based on the closest element that is non-statically
positioned. Otherwise, the offset for any statically positioned parent
other than the body will be considerably higher than it should be,
resulting in the dropdown being offset by a large amount.
The offset parent for the body element is the html element, which is why
this works for both the body element and any custom parents for the
dropdown. This would not be needed if the parent wasn't customizable (as
seen in Select2 3.x) because you will never need to offset the body
element if it is statically positioned, because the html element almost
never has an offset.
This also fixes JSHint issues within the tests added in the last commit.

This adds a regression test that verifies the problem with positioning
the dropdown when the parent is a statically positioned element that
still has an offset. This could typically be seen if the body element
has an offset, which unfortunately it almost always does because of the
default user stylesheet in browsers. This was not caught during
pre-release testing because all of the test pages reset the margins and
padding on the body element.
This regression test verifies that the offsets that should be set for
the dropdown are calculated correctly. These were surprisingly difficult
to do because of how the offset is calculated using different
positioning techniques.
These tests are for https://github.com/select2/select2/issues/3970
The old functionality where classes were directly copied to the
container can be done by setting `dropdownCssClass: ':all:'` when
initializing Select2.

This groups tests into common HTML files so they can be run more
quickly. This also reduces the number of Sauce Labs instances that
have to be run, as one instance was previously spun up for each
file.
This adds `StopPropagation` modules that will stop the propagation
of the most common events from the selection and dropdown containers.
These modules work from a list of 21 common events, most of which
were stopped by default in past versions, and call `stopPropagation`
on them when they are detected at the container level.
These modules are only available in full builds of Select2.

Now we are using `jQuery.noConflict()` in tests, so it should be
slightly easier to detect when this happens next time. Tests just
need to be written for the component.
This closes https://github.com/select2/select2/issues/2985.
This adds a check that triggers an error if Select2 was not able
to detect a copy of jQuery on the page. This should help users when
they are setting up Select2.
**Breaking change:** The full build no longer includes jQuery.
Previously, the full build included all requirements for Select2,
including jQuery, which meant that anyone looking for the optional
requirements had to possibly include multiple versions of jQuery
on their page. This means that anyone requiring Select2 to also
bundle jQuery will now need to include jQuery on their pages
alongside Select2. A copy of jQuery is included in the repository.
**Breaking change:** The AMD build of Select2 will now correctly
wrap the code in a `define` block. It will still create the named
blocks inside of the code, which should be valid in most AMD build
systems, so now Select2 is compatible with cases where the file
does not have the same name as the Select2 module name.
**Breaking change:** Select2 will re-use the AMD methods if they
are available on the page, but it will not longer leak the included
AMD loader to the global scope. The AMD methods will still be
available on the `jQuery.fn.select2.amd` namespace.
The `mock.js` test file has been renamed to `helpers.js` and will
handle the escalation of the `require` and `define` variables to
the global scope. It should be included in all test files, or the
tests will fail.
This closes https://github.com/select2/select2/issues/2946.
`selectOnClose` is a new option which works very much like the old
`selectOnBlur` option. When the `close` event is triggered, the
highlighted result is automatically selected. This is useful for
single selects, which is where it is designed to be used, but it
can also be used on multiple selects.
This also adds tests to verify that this works in the future.
During the creation of the test, we noticed that we were missing a
mock container that could be used for triggering events. One was
created and a general mock JS file was created to hold any future
mocks for tests.
