Subject: [PATCH v2 09/27] userdiff tests: match full hunk headers

From: Ævar Arnfjörð Bjarmason <[email-masked]>
Date: Mon, 15 Feb 2021 16:44:09 +0100

Fix a regression in the test framework for userdiff added in
bfa7d01413 (t4018: an infrastructure to test hunk headers,
2014-03-21).

The testing infrastructure added in that change went overboard with
simplifying the tests, to the point where we lost test coverage.

Before that we'd been able to test the full context line, or ever
since the feature was originally added in f258475a6e (Per-path
attribute based hunk header selection., 2007-07-06).

After bfa7d01413 all we cared about was whether "RIGHT" appeared on
the line. We thus lost the information about whether or not "RIGHT"
was extracted from the line for the hunk header, or the line appeared
in full (or other subset of the line).

Let's bring back coverage for that by adding corresponding *.ctx
files, this has the added advantage that we're doing a "test_cmp", so
when we have failures it's just a non-zero exit code from "grep",
we'll actually have something meaningful in the "-v" output.

As we'll see in a follow-up commit this is an intermediate step
towards even better test coverage. I'm structuring these tests in such
a way as to benefit from the diff.colorMove detection.

The "sed -n -e" here was originally a single 's/^.*@@\( \|$\)//p'
pattern, but the '\( \|$\)' part had portability issues on OSX and
AIX.

-How to write RIGHT test cases
-=============================
+How to write test cases
+=======================
+
+Create test cases called "LANG-whatever" in this directory, where
+"LANG" is e.g. the userdiff driver name, where "whatever" is a brief
+description of the test.
 
 Insert the word "ChangeMe" (exactly this form) at a distance of
 at least two lines from the line that must appear in the hunk header.
 
-The text that must appear in the hunk header must contain the word
-"right", but in all upper-case, like in the title above.
-
-This text is a bit twisted and out of order, but it is itself a
-test case for the default hunk header pattern. Know what you are doing
-if you change it.
-
-BTW, this tests that the head line goes to the hunk header, not the line
-of equal signs.
+The text that must appear in the hunk header must contains the word
+"RIGHT" by convention. The "LANG-whatever.ctx" file contains what we
+expect to appear in the hunk header. We munged away the starting "@@
+[...] @@" part of the line for ease of not having to hardcode the line
+numbers and offsets.
