PATCH: Slightly improve test harness

PATCH: Slightly improve test harness

[Thorsten Dahlheimer]

[-- Attachment #1: Type: text/plain, Size: 694 bytes --]

This patch makes the following changes to the test harness:

- abort the test if %prep code returns a non-zero status, as is
  documented in B01cd.ztst
- don't abort the test run if a testcase fails (unless there's a syntax
  error in the test file)
- make sure cleanup is always performed when exiting
- ZTST_getsect() used to always tolerate one junk line immediately
  before the beginning of a section; correct that
- don't print ZTST_message and ZTST_failmsg for syntax errors in the
  test file; instead always print the line number in that case
- make sure ZTST_message and ZTST_failmsg are always cleared upon exit
  from ZTST_test()
- improve progress bar

Regards,
Thorsten Dahlheimer

That change results in an erroneous "Test successful" message when a
test fails and verbosity is at least 1.  Did you check if any of the
test cases expected the success of an earlier test in a later test?
If so, it might be best to just leave the abort-after-the-first-failure
behavior unchanged.

> - make sure cleanup is always performed when exiting

That fixed trap code seems to make it impossible to Ctrl-C out of the
tests, though I'm not sure why yet.  Perhaps it's a bug in trap
handling, but zsh hangs when that cleanup trap in place and Ctrl-C is
pressed.

In the meantime, I've checked in a change that just disables the trap
line (since zsh now complains about its incorrect syntax).

..wayne..

As others have noted, the tests may be cascaded, expecting previous tests
to have finished successfully.  Please don't make this change.

What was wrong with it before, and how does this differ?

Ok, I've attached a new patch with this change undone.  It also corrects
an erroneous testcase in A06assign.ztst and replaces various hardcoded
paths to the newly-compiled zsh executable in the test files with
$ZTST_exe.

I could reproduce this when running on linux, so I left the trap
commented out.
