[libnftables PATCH 1/3] tests: fix error reporting

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The testbench was not reporting errors properly.

With this patch, "1" is returned to the shell if the test failed (instead of
returning "0" unconditionally). Textual reporting is also fixed.

In case of compilation without some parsing support, returning error (i.e 1)
is the expected behaviour.
