example of embedded project testing using RobotFramework

Example of RobotFramework test-suite for the simple ESP32 project. It contains example of test-suite for controlling ESP32 LED using serial port command, and checking LED status using RPi GPIO pin reading and dedicated BLE characteristic value reading. Also this repository contains a short article in Russian about using RobotFramework for embedded testing

Hardware requirements:

• Raspberry Pi 4B
• ESP32S Devkit V1 board

Software requirements:

• robotframework
• robotframework-seriallibrary
• wiringpi

Environment configuration

The following packages should be installed on Raspberry PI:

pi@raspberrypi: pip3 install robotframework robotframework-seriallibrary pygatt
pi@raspberrypi: sudo apt install wiringpi

RPi4 should be connected to ESP32 board as it is shown on the picture

Two nets should be connected using wires:

• Ground
• ESP32 D2 pin should be connected to RPi GPIO.0 pin

Run tests

pi@raspberrypi:~/Documents/robot_examples_for_embedded $ robot robot_files/esp32_tests.robot

Tests result
