Local CI, for mortals.

Project description

Note: EasyCI only works with git repositories.

Never worry about checking in broken code again. No need to maintain a CI server. No need to shell out ridiculous amount of money for your personal project. EasyCI puts your mind at ease, like a good CI service, but without all the extra costs.

EasyCI operates via git pre-commit and pre-push hooks to ensure that your code passes tests before letting you commit/push.

$ git commit
Running test: flake8
[master b2e6fa1] test commit
1 file changed, 2 insertions(+), 2 deletions(-)

EasyCI also makes sure not to run tests redundantly. If you ran tests before using eci test, and no files have changed, then it does not try to run tests again.

$ eci test
Running test: flake8
$ git commit
OK Files not changed
[master b2e6fa1] test commit
1 file changed, 2 insertions(+), 2 deletions(-)

This means that if you run tests regularly as part of your workflow, there is effectively no efficiency cost in using EasyCI, yet you can rest easy knowing that if you forgot to run tests, you will not be allowed to commit/push.

EasyCI is designed to shift the burden of test running away from you. To that end, it is possible to have EasyCI monitor your project for changes and automatically run tests, so that by the time you want to commit your changes, your tests would have already been run. Do this in a separate shell session:

$ # from anywhere in your project
$ eci watch
Watching directory `/path/to/project`. Use ctrl-c to stop.


First, install EasyCI using pip.

pip install easyci

Next, setup EasyCI for your project.

cd /path/to/project
eci init

This will install the necessary git hooks and put a trivial config file eci.yaml. You should modify the config file to actually run your tests.

Running Tests

Tests are run automatically by git’s pre-commit and pre-push hooks. To trigger tests manually:

# from anywhere in your project
eci test

Collecting Test Results

EasyCI preserves the state of your project by making a copy of your project using rsync to a temporary directory. In some cases, you do want the files generated by your tests. For example, if your tests generate code coverage data, or other tests data, you will want the options to copy those files from the temporary directory back to your project directory. This can be done by the config collect_results.

As an example, the following config will copy everything under the subdirectory htmlcov, which in this case contains the code coverage report.

    - coverage run -m py.test && coverage html
    - htmlcov/***

For more information on the pattern format for collect_results, see the man page for rsync, which is used internally to copy the test results.


The config lives in a file at the root of the repository, eci.yaml.

key type Description
tests List[string] This is a list of commands to run tests.
history_limit int The number of passing test runs to remember.
collect_results List[string] Copy files matching these patterns back to the project. The patterns must be in an rsync-compatible format.


All commands should be run inside the target repository.

eci init

Initialize the project for use with EasyCI. This installs the necessary git hooks (pre-commit + pre-push) and add a config file if one does not already exists.

eci test

Run tests. If a passing test run is found in the tests run history, then this does not run any tests.

eci watch

Watch the current repository for changes and automatically run tests.

eci gc

Runs housekeeping tasks to free up space. For now, this only removes saved but unused (unreachable) test results.

eci clear-history

Clear tests run history. History is normally used to keep track of whether a test has been run for a specific state of the project, to avoid running tests redundantly. This command clears the history, causing the next eci test command to always run tests.
