Overview

shUnit2 is a xUnit unit test framework for Bourne based shell scripts, and it is designed to work in a similar manner to JUnit, PyUnit, etc. If you have ever had the desire to write a unit test for a shell script, shUnit2 can do the job.

shUnit2 was originally developed to provide a consistent testing solution for log4sh, a shell based logging framework similar to log4j. During the development of that product, I repeatedly ran into the problem of having things work just fine under one shell (`/bin/bash` on Linux to be specific), and then not working under another shell (`/bin/sh` on Solaris). Although I had some simple tests that I ran, I finally decided to develop a more robust unit test framework after releasing multiple brown-bag releases.

Rather than reinvent the wheel again, I chose to base the shUnit2 framework as much as possible on JUnit. I wanted something that was both incredibly easy to use, but that was as well incredibly powerful. I knew that the code would be built only for log4sh at the start, but hoped that someday I could release the code as a separate project. Now that the code is stable and mature enough, I have done just that.

You might ask why I didn't just use the already existing ShUnit product. I took a look at it, but wasn't really happy with how it worked or how little it reflected the way JUnit and other unit test frameworks function. As such, I figured that it was probably better just to write my own.

shUnit2 has been developed under the Bourne Again Shell (`/bin/bash`) on Linux, but _great care_ has been taken to make sure it works under the other Unix shells to insure maximum compatibility. If you like what you see, or have any suggestions on improvements, please feel free to drop me an email.

Downloading

There are two current release series of shUnit2 available. The 2.0 series is the stable release, and it contains only bug fixes. The 2.1 series is meant for new features and is still under active development. The 2.1 series of shUnit2 has its own set of unit tests, and should be considered fine for daily use.

If you would like to verify the GPG signatures of the releases, please take a look at my GnuPG Info page.
