Change #!/bin/bash at start of tests to "#!/usr/bin/env bash". That way
systems running on bash < 4 can prepend bash >= 4 to path before
running the tests.
A bug in the results-aggregation code was causing the test suite to report
"all tests passed" even when there were failures, (as long as there were
also no "broken" tests). Fix this.
This makes the new, git-derived test suite report results in a manner
similar to the original notmuch test suite.
Notable changes include:
* No more initial '*' on every line
* Only colorize a single word
* Don't print useless test numbers
* Use "PASS" in place of "ok"
* Begin sentences with a capital letter
* Print test descriptions for each block
* Separate each block of tests with a blank line
* Don't summarize counts between each block
Git uses a simple and yet powerful test framework, written in shell.
The framework is easy to use for both users and developers so I think
it would help if it is used in notmuch as well.
This is a copy of Git's test framework from commit
b6b0afdc30e066788592ca07c9a6c6936c68cc11 in git repository.
