Subject: tests/example/check: Better handling of makefile updates
X-Git-Tag: subdirmk/0.3~88
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ian/git?p=subdirmk.git;a=commitdiff_plain;h=1e8cf1c577b74d3d83a17a9f1ae163eeae3e700d

tests/example/check: Better handling of makefile updates

Rather than checking just for presence of a string in a templated
output file, also have the input file define a target which we try to
run.  This checks that make actually reread the file.

Also add ||false to the grep lines, which makes the stderr output
more obviously contain a failure when the test fails.
