Continuous integration

**Target**: Testing is run at appropriate times without human involvement and reports are direct and concise.

**User Story**: As a person responsible for software quality and correctness for my project, I want code regularly tested so that regressions are guarded against and new code is tested against itself and other commits the developer might not have had.

- [ ] Regression and unit tests exist but are only run when requested by a developer.
- [ ] Tests are run automatically according to the teams policy.
- [ ] Test reports are generated as needed and archived.
- [ ] Archived reports are posted to appropriate maintainers.
- [ ] Code may not be integrated if automated tests fail.
- [ ] A mechanism and policy exists to integrate code without passing tests in rare circumstances.
