travisci-gcc-arm-test

Test Travis CI integration with GCC ARM projects using Throw The Switch's Unity unit-testing framework for C unit tests.

This is a test repository that demonstrates a proof-of-concept for the University of Waterloo's Midnight Sun Solar Rayce Car team's software team (our GitHub organization can be found at uw-midsun).

Usage

To use, just enable the Travis CI integration for your project, and then modify the .travis.yml file as appropriate. Currently, the configuration has Travis:

1. Install dependencies from the ppas
2. Build GNU Make from source

After cloning the project repository, it updates all the submodules using

git submodule update --init --recursive

And then builds a project:

make build_all PLATFORM=$PLATFORM

Our Makefile is set up such that it returns the exit code in $?. So Travis CI will detect that make failed, and will report the appropriate error code.

We're also making use of Travis' build matrix, to test a wide variety of environments. Essentially, by declaring certain options, Travis will take those options, and run a build for every possible permutation of the options. In .travis.yml, this is done by:

env:
  - PLATFORM=x86
  - PLATFORM=stm32f0xx

The following code block will make Travis run twice, once for each version of PLATFORM. Any new platforms should be added here to the build matrix.
