2 A [`Makefile`](https://github.com/shaarli/Shaarli/blob/master/Makefile) is available to perform project-related operations:
4 - Documentation - generate a local HTML copy of the GitHub wiki
5 - [Static analysis](Static analysis) - check that the code is compliant to PHP conventions
6 - [Unit tests](Unit tests) - ensure there are no regressions introduced by new commits
9 [Travis CI](http://docs.travis-ci.com/) is a Continuous Integration build server, that runs a build:
11 - each time a commit is merged to the mainline (`master` branch)
12 - each time a Pull Request is submitted or updated
14 A build is composed of several jobs: one for each supported PHP version (see [Server requirements](Server requirements)).
19 - installs 3rd-party test dependencies with Composer
20 - runs [Unit tests](Unit tests)
22 After all jobs have finished, Travis returns the results to GitHub:
24 - a status icon represents the result for the `master` branch: [![](https://api.travis-ci.org/shaarli/Shaarli.svg)](https://travis-ci.org/shaarli/Shaarli)
25 - Pull Requests are updated with the Travis result
26 - Green: all tests have passed
27 - Red: some tests failed
28 - Orange: tests are pending
