1768874 - Figure out a better setup for the style crate's unit tests.

Status: NEW

(Core :: CSS Parsing and Computation, defect)

Description

[Emilio Cobos Álvarez (:emilio)]

In bug 1768301, ccov builds failed because using -Clink-dead-code causes the style crate to pull a bunch of libxul / Gecko code.

In the past there used to be more tests, but at this point, other than the piecewise-linear function tests introduced in bug 1764126, it's mostly a bunch of sizeof tests.

There are various things that could be done here, but something that looks a bit appealing would be to move the sizeof tests to the style crate itself (to happen at build-time, like a static_assert), and maybe move the piecewise linear function to a separate crate (since it doesn't depend on much from the style crate, actually).

Then we can remove these tests altogether.
