About this Project
The CPAN Testers project is an effort to ensure the stability and reliability of Perl and CPAN by running the test suites of uploaded CPAN distributions on various Perl versions, OSes, and hardware; collecting the results in a database; and alerting distribution authors when there is a test failure.
The CPAN Testers Backend handles all the data processing that turns the incoming test reports into useful information to be consumed by users of the API and web application. The goal of this subproject is to contain all the backend code and support routines needed to manage the CPAN Testers data (delegating to the CPAN::Testers::Schema as much as possible).
This project follows CPAN conventions with some additions, explained below.
Modules are located in the
lib/ directory. Most of the functionality
of the project should be in a module. If the functionality should be
available to users from a script, the script should call the module.
Many of the modules in this project are executable modules using the Beam::Runner framework.
All the tests are located in the
t/ directory. See "Getting Started"
below for how to build the project and run its tests.
Any extra tests that are not to be bundled with the CPAN module and run by consumers is located here. These tests are run at release time and may test things that are expensive or esoteric.
Any files that are not runnable code but must still be available to the
code are stored in
share/. This includes default config files, default
content, informational files, read-only databases, and other such. This
project uses File::Share to
locate these files at run-time.
This directory contains additional things that aren't examples (which
would go in
eg/), but also must not be part of the CPAN distribution
(which would go in
The files in this directory are Beam::Wire container files which are used to configure the various tasks that are available to run.
By adding this directory to the BEAM_PATH environment
variable, the container files
will be listed by the
beam list command, making it easy to see what
tasks are available.
These are runit service files used to run processing daemons.
What to Contribute
The issue tracker is used for both bug reports and to-do list. Anything on the issue tracker, open or closed, is available for discussion.
For fixes, simply fork and send a pull request. Fixes to anything, documentation, code, tests, are equally welcome, appreciated, and addressed!
If you are fixing a bug in the code, please add a regression test to ensure it stays fixed in the future.
All contributions are welcome if they fit the scope of this project. If you're not sure if your feature fits, open an issue and ask. If it doesn't fit, we will try to find a way to enable you to add your feature in a related project (if it means changes in this project).
When contributing a feature, please add some basic functionality tests to ensure the feature is working properly. These tests do not need to be comprehensive or paranoid, but must at least demonstrate that the feature is working as documented.
Getting Started Building and Running Tests
This project uses Dist::Zilla for its releases, but you aren't required to use it for contributing.
These instructions do require you have
App::cpanminus (cpanm) installed.
cpanm is a CPAN client to install Perl modules and programs. You can
cpanm by doing:
curl -L https://cpanmin.us | perl - App::cpanminus
Or, if you (not incorrectly) do not trust that, by using the existing
cpan client that comes with Perl:
You may need to be root or Administrator to install cpanminus.
cpanm to install prereqs
cpanm command is the
easiest way to install this project's dependencies. In the root of the
project, just run
cpanm --installdeps . and the dependencies will be
carton to install prereqs in an isolated directory
If you wish to isolate the prerequisites of this project so they do not
interfere with other projects, you can use the
Carton tool. Install Carton normally
from CPAN using
cpanm Carton, then use the
carton command to install
this module's prereqs in the
Once the prereqs are installed, you can use
carton exec prove -lr t
to run all the tests with the right prereqs. Putting
carton exec in
front of the command makes sure Perl uses the right library
prove to run tests
Perl comes with a utility called
prove which runs tests and gives
a report on failures. To run the test suite with
prove -lr t
This will run all the tests in the
t directory, recursively, while
adding the current
lib/ directory to the library path.
You can run individual test files more quickly by passing them as arguments to prove:
prove -l t/my-test.t
Using Dist::Zilla to install prereqs and run tests
Once you have installed Dist::Zilla via
cpanm Dist::Zilla, you can get
this distributions's dependencies by doing:
dzil listdeps --author --missing | cpanm
Once all that is done, testing is as easy as:

Code Formatting and Style
Please try to maintain the existing code formatting and style.
- 4-space indents
- Opening brace on the same line as the opening keyword
- Exceptions made for lengthy conditionals
- Closing brace on the same column as the opening keyword
Documentation is incredibly important, and contributions will not be accepted until documentated.
- Methods must be documented inline, above the code of the method
- Method documentation must include name, sample usage, and description of inputs and outputs
- Attributes must be documented inline, above the attribute declaration
- Attribute documentation must include name, sample value, and description
- User-executable scripts must be documented with a short synopsis, a longer description, and all the arguments and options explained
- Tests must be documented with the purpose of the test and any useful information for understanding the test.
Though this project has a
Makefile.PL, and maybe even
Build.PL, these files are auto-generated and should not be edited.
To add new prereqs, you must add them to the
dist.ini file in the
[Prereqs]- Runtime requirements
[Prereqs / TestRequires]- Test-only requirements
[Prereqs / Recommends]- Runtime recommendations, for optional modules
[Prereqs / TestRecomments]- Test-only recommendations, for optional modules
If the section doesn't already exist, you can add it to the bottom of
TestRecommends will be automatically installed by
Travis CI to test those parts of the code.
OS-specific prerequisites can be added using the Dist::Zilla::Plugin::OSPrereqs module.
