Wokwi Part Tests

This repository contains a set of test projects for many Wokwi parts. The tests can be compiled using platformio and then run using the Wokwi CLI.

List of Tests

board-ssd1306
- ESP32
wokwi-dht22
wokwi-ili9341
- Arduino Uno
wokwi-micro-sd
- ESP32
wokwi-slide-potentiometer
- Arduino Uno
- ESP32

Running the tests

To build the test projects and run the tests, you need to install PlatformIO Core and the Wokwi CLI, get a Wokwi CI token and set the WOKWI_CLI_TOKEN environment variable with the token.

Then use pio run to compile the project and wokwi-cli . --scenario <scenario_file_name>.yaml to run the tests. You can also use Wokwi for VS Code to interactively simulate the test projects.

For example, to compile and run the tests for the wokwi-dht22 part on the ESP32, you can use the following commands:

cd wokwi-dht22/dht22-esp32
pio run
wokwi-cli . --scenario dht22.test.yaml

The output of the test should look as follows this:

Wokwi CLI v0.16.0 (ff220a404971)
