Travis CI

Travis CI officially supports PlatformIO for Embedded Builds.

Travis CI is an open-source hosted, distributed continuous integration service used to build and test projects hosted at GitHub.

Travis CI is configured by adding a file named .travis.yml, which is a YAML format text file, to the root directory of the GitHub repository.

Travis CI automatically detects when a commit has been made and pushed to a GitHub repository that is using Travis CI, and each time this happens, it will try to build the project using platformio ci command. This includes commits to all branches, not just to the master branch. Travis CI will also build and run pull requests. When that process has completed, it will notify a developer in the way it has been configured to do so — for example, by sending an email containing the build results (showing success or failure), or by posting a message on an IRC channel. It can be configured to build project on a range of different Development Platforms.

Integration

Please make sure to read Travis CI Getting Started and general build configuration guides first.

Note

If you are going to use PlatformIO Unit Testing or PIO Remote™ you will need to define PLATFORMIO_AUTH_TOKEN environment variable in project settings. See Defining Variables in Repository Settings guide.

PlatformIO is written in Python and is recommended to be run within Travis CI Python isolated environment:

language: python
python:
    - "2.7"

# Cache PlatformIO packages using Travis CI container-based infrastructure
sudo: false
cache:
    directories:
        - "~/.platformio"

env:
    - PLATFORMIO_CI_SRC=path/to/test/file.c
    - PLATFORMIO_CI_SRC=examples/file.ino
    - PLATFORMIO_CI_SRC=path/to/test/directory

install:
    - pip install -U platformio

script:
    - platformio ci --board=<ID_1> --board=<ID_2> --board=<ID_N>

Then perform steps 1, 2 and 4 from http://docs.travis-ci.com/user/getting-started/

For more details as for PlatformIO build process please look into platformio ci.

Project as a library

When project is written as a library (where own examples or testing code use it), please use --lib="." option for platformio ci command

script:
    - platformio ci --lib="." --board=<ID_1> --board=<ID_2> --board=<ID_N>

Library dependencies

There 2 options to test source code with dependent libraries:

Install dependent library using Library Manager

install:
    - pip install -U platformio

    #
    # Libraries from PlatformIO Library Registry:
    #
    # http://platformio.org/lib/show/1/OneWire
    - platformio lib -g install 1

Manually download dependent library and include in build process via --lib option

install:
    - pip install -U platformio

    # download library to the temporary directory
    - wget https://github.com/PaulStoffregen/OneWire/archive/master.zip -O /tmp/onewire_source.zip
    - unzip /tmp/onewire_source.zip -d /tmp/

script:
    - platformio ci --lib="/tmp/OneWire-master" --board=<ID_1> --board=<ID_2> --board=<ID_N>

Custom Build Flags

PlatformIO allows to specify own build flags using PLATFORMIO_BUILD_FLAGS environment

env:
    - PLATFORMIO_CI_SRC=path/to/test/file.c PLATFORMIO_BUILD_FLAGS="-D SPECIFIC_MACROS_PER_TEST_ENV -I/extra/inc"
    - PLATFORMIO_CI_SRC=examples/file.ino
    - PLATFORMIO_CI_SRC=path/to/test/directory

install:
    - pip install -U platformio
    - export PLATFORMIO_BUILD_FLAGS="-D GLOBAL_MACROS_FOR_ALL_TEST_ENV"

For the more details, please follow to available build flags/options.

Advanced configuration

PlatformIO allows to configure multiple build environments for the single source code using Project Configuration File platformio.ini.

Instead of --board option, please use platformio ci --project-conf

script:
    - platformio ci --project-conf=/path/to/platoformio.ini

Unit Testing

See PlatformIO Remote Unit Testing Example.
