Can someone give me guidance on how to write a test case? I am trying to
write a test case for a new flag that generates a file (much like
-ddump-to-file).
I started by trying to cat the generated file to get it into the
stdout/stderr
+test('T8624', normal, run_command,+ ['echo $MAKE && $MAKE T8624
&& cat T8624.th.hs'])
But I get this error:
cd . && echo $MAKE && $MAKE T8624 && cat T8624.th.hs </dev/null
>T8624.run.stdout 2>T8624.run.stderrmakemake[1]: Entering directory
