Urchin is an experimental language-agnostic lightweight cross-platform test skeleton
written in POSIX-compliant shell, originally designed for test-driven server deployment
at <a href="https://scraperwiki.com">ScraperWiki</a>.

## Install
Downlolad Urchin like so

    wget https://raw.github.com/scraperwiki/urchin/master/urchin
    chmod +x urchin

Now you can run it.

    ./urchin

## Writing tests
Make a directory named `tests`. Inside it, put files that begin with `test`
that exit `0` on success and something else on fail. Then run urchin from
the parent directory of the `tests` directory.

## More about writing tests
Tests are organized recursively in directories, where the names of the files
and directories have special meanings.

    tests/
      setup
      bar/
        setup
        test_that_something_works
        teardown
      baz/
        jack-in-the-box/
          setup
          test_that_something_works
          teardown
        cat-in-the-box/
          fixtures/
            thingy.pdf
          test_thingy
      teardown

Directories are processed in a depth-first order. When a particular directory
is processed, `setup` is run before everything else in the directory, including
subdirectories. Use `urchin_export`, which works like `export`, to set variables
in the setup function and make them available to other files in the same
directory.

`teardown` is run after everything else in the directory. The "everything else"
actually only includes files whose names contain "test". The test passes if the
file exits 0; otherwise, it fails.

Aside from files named '`setup`' or '`teardown`', files and directories are run
only if they start with '`test`'. Thus, fixtures and libraries can be included
sloppily within the test directory tree.
