This is so that the filename of the test doesn't clash with the module name
itself (being "websocket"), and lead to potential problems executing the
test.
MICROPY_LONGINT_IMPL_LONGLONG doesn't have overflow detection, so just
parsing a large number won't give an error, we need to print it out
to check that the whole number was parsed.
These short unit tests test the base uPy methods as well as parts of the
websocket protocol, as implemented by uPy.
@dpgeorge converted the original socket based tests by @hosaka to ones
that only require io.BytesIO.
This test just tests that the basic functions/methods can be called with
the appropriate arguments. There is no real test of underlying
functionality.
Thanks to @hosaka for the initial implementation of this test.
I.e. they don't run successfully with MICROPY_LONGINT_IMPL_NONE
and MICROPY_LONGINT_IMPL_LONGLONG (the problem is that they generate
different output than CPython, TODO to fix that).
The use of large literal numbers is a big no-no when it comes to writing
programs which work with different int representations. Also, some checks
are pretty adhoc (e.g using struct module to check for 64-bitness). This
change bases entire detection on sys.maxsize and integer operarions, and
thus more correct, even if longer.
Note that this change doesn't mean that any of these tests can pass with
anything but MPZ - even despite checking for various int representations,
the tests aren't written to be portable among them.
Tests which don't work with small ints are suffixed with _intbig.py. Some
of these may still work with long long ints and need to be reclassified
later.
