The fact that a `MarkedValueList` had to be created was just annoying,
so here's an alternative.
This patchset also removes some (now) unneeded MarkedValueList.h includes.
LibJS doesn't store stacks for exception objects, so this
only amends test-common.js's __expect() with an optional
`details` function that can produce a more detailed error
message, and it lets test-js.cpp read and print that
error message. I added the optional details parameter to
a few matchers, most notably toBe() where it now prints
expected and actual value.
It'd be nice to have line numbers of failures, but that
seems hard to do with the current design, and this is already
much better than the current state.
This enables a nice warning in case a function becomes dead code. Also,
in the case of test-crypto.cpp, I took the liberty to add the prefix 'g_'
to the global event loop.
Skipped tests count as a "pass" rather than a "fail" (i.e. a test suite
with a skipped test will pass), however it does display a message when
the test is printing.
This is intended for tests which _should_ work, but currently do not.
This should be preferred over "// FIXME" notes if possible.
This commit also exposes JSONObject's implementation of stringify to the
public, so that it can be used by test-js without having to go through
the interpreter's environment.
This moves most of the work from run-tests.sh to test-js.cpp. This way,
we have a lot more control over how the test suite runs, as well as how
it outputs. This should result in some cool functionality!
This commit also refactors test-common.js to mimic the jest library.
This should allow tests to be much more expressive :)
