Arduino blink with cpputest

This repo seeks to demonstrate the use of cpputest on an arduino project.

It contains:

• The basic arduino blink example
• The cpputest starter project (located in unit_tests/)
• ArduinoFake(located in unit_tests/mocks)

It is failing to compile right now because it is unable to #import "ArduinoFake.h"

There is a single test in unit_tests/tests/. Right now it will pass because the following 2 lines (suggested on ArduinoFake's getting started section) are commented out:

#include "ArduinoFake.h" using namespace fakeit;

Build and compile

using Arduino-CLI

1. Set environment variables (this FQBN is for the ESP32-nano): FQBN=arduino:esp32:nano_nora && PORT=</dev/ttyUSB0 OR COM3> && FILENAME=blink-arduino-cpputest.ino

2.Compile arduino-cli compile --fqbn $FQBN $FILENAME --output-dir build

3. Upload arduino-cli upload -p $PORT --fqbn $FQBN $FILENAME --input-dir build

You can also chain the commands together like so: arduino-cli compile --fqbn $FQBN $FILENAME --output-dir build && arduino-cli upload -p $PORT --fqbn $FQBN $FILENAME --input-dir build

in case of this error on Linux: dfu-util: No DFU capable USB device available download and execute this script

Test

1. Build the docker image (one time only, or on Dockerfile updates): sudo docker pull jwgrenning/cpputest-runner

2. Run the tests: ./unit-tests/docker/run.sh "make -C unit-tests" or ./unit-tests/docker/run.sh "legacy-build make unit-tests ."

3. Alternatively, install cpputest natively and run make all from within the unit_tests folder
