# Subplot -- acceptance criteria documentation and verification

Capture and communicate acceptance criteria for software and systems,
and how they are verified, in a way that's understood by all project
stakeholders.

Acceptance criteria are expressed as _scenarios_ in the Cucumber
given/when/then style:

> given a web site subplot.liw.fi
> when I retrieve the site front page
> then it contains "Subplot"
> and it contains "acceptance criteria"


## When all stakeholders really need to understand acceptance criteria

Subplot is a set of tools for specifying, documenting, and
implementing automated acceptance tests for systems and software.
Subplot tools aim to produce a human-readable document of acceptance
criteria and a program that automatically tests a system against those
criteria. The goal is for every stakeholder in a project to understand
the project’s acceptance criteria and how they’re verified.

See <https://subplot.liw.fi/> for the home page.

## Hacking Subplot

Subplot is written using the Rust programming language, so the usual
workflow for Rust applies.

* To build: `cargo build`
* To run tests: `cargo test`
* To format code: `cargo fmt`

You probably need to install Rust using rustup: the version packaged
in a Linux distribution is likely too old. When you install Rust,
ensure you have the following installed:

* `rustc`
* `cargo`
* `rustfmt`

To run the whole test suite, including testing all examples and
Subplot self tests, run `./check` at the root of the source tree.

You'll need to install some build dependencies. On a system running
Debian or a derivative of it:

~~~sh
$ sudo apt-get install build-essential git debhelper python3 \
  librsvg2-bin graphviz plantuml daemonize procps
~~~

Additionally, any packages reported by running the following command:

~~~sh
$ dpkg-checkbuilddeps
~~~

To build the Debian package:

~~~sh
$ git archive HEAD | gzip > "../subplot_$(dpkg-parsechangelog -SVersion | sed 's/-.*$//').orig.tar.gz"
$ dpkg-buildpackage -us -uc
~~~
