The GError object has to initialized to NULL before being passed to
g_file_set_contents or it will throw the following critical warning
GLib-CRITICAL **: g_file_set_contents: assertion 'error == NULL || *error == NULL' failed
and return FALSE, which leads to failed assertion and subsequently
to the test failing
The boundary test-case with SR_GHZ(18446744073ULL) currently fails, but
that is not practically relevant so comment it out for now, until we add
a proper fix.
This adds a suite of unit tests for libsigrok. It uses the 'Check'
tool/library (apt-get install check) to run the tests.
The configure tool tries to find libcheck. If it succeeds, a
"make check" will run all tests. Otherwise, none of the tests will
be built and "make check" will not run any tests.
This also means that users who don't have 'check' installed will still
be able to build and install libsigrok just fine.
