Unit Testing
This page will track the effort to improve unit test and other automated test coverage for OpenSSL. Everyone is encouraged to help with this effort, but this page will track which community members have accepted specific responsibilities, and what tasks are currently underway.
Team
We can define new roles as needed. The success of this effort will be inversely proportional to the number of roles with any one individual's name next to them. Each role can have more than one person filling it, but needs specific people to fill them.
The point is not to tell people what to do and not do: it’s to establish clear responsibilities so everyone can run with them right away and begin applying their creative energy to solutions, rather than waste it figuring out what the hell is going on, what they should do to contribute, and who they need to coordinate with to get things done.
Organizer: Mike Bland
Ensures the overall effort is making progress by facilitating communication, removing obstacles, and making hands-on contributions when necessary.
Tech Writer: Mike Bland, Sandeep Mankar, Chelsea Komlo
Maintains documentation of tools, techniques, outstanding issues, etc. May maintain a code review/testing style guide based on the community consensus. Also documents who currently fills each role, as well as who might've filled it in the past.
Buildmaster: Mike Bland, Isaac Truett
Sets up and maintains automated builds and any infrastructure used to monitor them and report breakage.
Toolsmith: Tony Aiuto Maintains any tools and frameworks that are a part of the core build process; proposes, integrates, and/or retires existing tools.
Tutor: Mike Bland, Darshan Mody, Tom Francis, Brian N. Makin, Chelsea Komlo, Edward Knapp
Helps contributors, particularly new contributors, with the details of writing unit or other automated tests. May be assigned by the reviewer of a patch to help a contributor get a new change under test. Submission of the patch should require the approval of the tutor in most cases. (Should ideally be more than one person.)
Goals
We can add more concrete goals to this list after we make progress on these. Getting people to own roles, setting up build infrastructure, and setting and enforcing policy are important first steps. Upon that foundation, we can begin to make serious progress towards improved test coverage, code quality, and defect prevention.
- Establish a written contribution/code review policy that requires:
- tests for every new code change, except for very trivial changes that do not directly impact program logic (e.g. documentation fixes, string constant updates, build script tweaks); this can be limited to an agreed-upon subset of the code to start, but would hopefully be expanded to cover most, if not all, of the code base
- tests for every bugfix
- smaller, well-tested changes building up to a complete feature (as opposed to large and/or untested changes that implement a large, complex feature all at once)
- Establish a schedule of Build Cops and Tutors to begin enforcing rollbacks/fixes and to help shepherd new contributors through the testing process.
- Set up a series of publicly-accessible continuous integration servers using whatever system the community prefers (e.g. Jenkins, Buildbot, etc.). These can be dedicated hardware or possibly Amazon Web Services-based. Establish a written policy that these remain green at all times, and that breakages be rolled-back or fixed within no more than 30 minutes.
