/**
* The mouse navigation tests are based on the following slider properties:
*
* initial value: 3 or [3, 7]
* ticks: [0, 3, 5, 7, 10]
* step: 0.1
*
* When the values are in the range from 0 to 10 and the step is 0.1, every value
* can be represented as 1% of the range. For example, 5.5 is 55% and 5.6 is 56%.
* This makes it easier to test the behaviour of tick locking.
*
* The mouse clicks are based on a percentage that represents where the user clicked
* on the slider (60% = 6.0). The percentage is then used to calculate the coordinates
* for the mouse events (mousedown, mousemove, and mouseup).
*
* These tests are setup to test for all combinations of relevant slider configurations:
* single/range, horizontal/vertical orientation, LTR/RTL, and ordered/reversed.
* The tests also check that the handles have the correct positioning, which should
* match the ticks that the handles lock to.
*
* The test data was carefully chosen based on following the test logic below.
*
* The test logic for sliders:
* - Clicking to the left of the handle should not change its value
* - Clicking to the left of the handle should change its value and lock to another tick
* - Ditto for clicking to the right of the handle
*
* For range sliders, the same logic is applied except test both handle1 and handle2.

* The keyboard navigation tests are based on the following slider properties:

* initial value: 3 or [3, 7]
* ticks: [0, 3, 5, 7, 10]
* step: 0.1
*
* See description for mouse navigation tests for explanation for test setup values.
*
* These tests are setup to test for all combinations of relevant slider configurations:
* single/range, horizontal/vertical orientation, LTR/RTL, natural keys navigation,
* ordered/reversed, and all key presses (left, up, right, down).
*
* The test data is fairly straightforward and passes most configurations except for
* special cases when using natural key navigation. For these cases, the test data
* had to be 'inverted'. For example, the test data had to be inverted when the
* slider has a horizontal orientation with either RTL or reversed option set (but not both).
*
* The test logic for sliders:
* - Key to the left should change the value and lock to the tick to the left
* - Key to the right should change the value and lock to the tick to the right
*
* For range sliders, the same logic is applied except test both handle1 and handle2.
