Sharnessify

Sharnessify contains scripts to easily add Sharness infrastructure to a project.

Purpose and Goal

Sharness is a great test framework written in Shell. It is actively developed and comes from Git itself.

Although you can embed Sharness files into your project, it is not so easy to do it cleanly while making it possible to update these Sharness files. Also some people don't want to mix the GPLv2 Sharness files with their own files that are licensed differently.

That's why the goal of this project is to make it easy to cleanly install Sharness support, so that Sharness files are separated from other files and can easily be installed and updated.

Usage

Clone this repo to a temporary directory and run sharnessify.sh with the path to your project:

$ cd ~/dev/my-project

$ git clone git://github.com/chriscool/sharnessify /tmp/sharnessify

$ /tmp/sharnessify/sharnessify.sh .

$ git status
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

  new file:   sharness/.gitignore
  new file:   sharness/Makefile
  new file:   sharness/lib/install-sharness.sh
  new file:   sharness/t0000-sharness.sh

Now run git commit and your project is equipped with sharness!

How it works

The sharnessify.sh script adds a Sharness install and update script called install-sharness.sh and then runs it to install Sharness. A .gitignore to ignore Sharness, a sample Sharness test script called t0000-sharness.sh and a Makefile to run all the Sharness tests are also added.

The sharnessify.sh script accepts an optional directory as argument. Passing no argument is like passing ., that is the current directory from which sharnessify.sh is run. This directory is where the sharness directory will be created. And sharnessify.sh will put everything it creates or fetches in this sharness directory.

This sharness directory will contain the following:

Makefile: to run Sharness tests using simply make
t0000-sharness.sh: a sample Sharness test, just to check that Sharness itself is working
lib a directory that itself contains:
- install-sharness.sh: a script to install and update Sharness
- sharness: a directory where Sharness is cloned and updated
.gitignore: a Git config file to tell Git to ignore lib/sharness, the directory where Sharness is cloned, and also the directories where Sharness runs the tests and stores their results

The above files that are not in the sharness/lib/sharness directory are all MIT licensed, so it should not be a problem to add them to your project. The sharnessify.sh script will perform a git add on them, but will not git commit them. You should do that though to finish the sharnessification.

Updating Sharness

When the install-sharness.sh script is copied, the Sharness version that this script should install is specified in the version variable at the top of the install-sharness.sh script. This version variable is set to the SHA1, also called object id, of the last Git commit in the Sharness repository used to clone Sharness.

By default the Sharness repository used to clone Sharness is the cannonical repository from GitHub (https://github.com/chriscool/sharness.git). But you can use a local repository instead by passing the -l <local>, or --local <local>, option to sharnessify.sh. If you do that then this <local> repository will also be used by install-sharness.sh, as it will be specified in the urlprefix variable at the top of install-sharness.sh.

So if you want to update Sharness, you only need to change the version, and maybe also the urlprefix variables at the top of install-sharness.sh. As the Makefile calls install-sharness.sh before running the test scripts, Sharness will be updated the next time the tests are run. Or you can update Sharness by directly running install-sharness.sh.
