kata-tracker

Track state and trend of your Java/JVM kata/dojo workflow.

This once will become a maven-central-hosted junit-extension. Until then the easiest way to use it is:

Check out this project
Start the CounterDisplay or the TimeSeriesChart (or both)
~~Do a kata and annotate your test class with @RedGreenTracking <-- no more needed since in this project we use ServiceLoader for auto registering the extension~~
Do a kata and have fun :)

Seen at our first Samman Society Unconference at Vienna in 2024.

At the moment it consists of three parts:

JUnit extension that sends the result of tests to a MQTT broker.
Tracker that counts green/red. The UI code was copies from Llew but instead of reading from file it gets its values by subscribing to the mqtt broker. Also the UI plays the red/green sound files by itself, they also were included what Llew did.

Graph that shows the red/green timeline and some statistics such as "longest time in red". The values are also retrieved by subscribing to the mqtt broker.

The UIs start and stop a MQTT broker within the JVM if there is no server running on port 1883 (default mqtt port)

...more to come

If you run multiple tests, each result is published, so gren, red, green, green test results in four tests would count as as very short red phase
If one of the UIs started the MQTT broker the broker will stop if this UI is stopped

Write to File (as it used to be) so nothing gets lost even if no server is running
- If so: Write single filed for performance reasons (the extension would then not have to append data), that puts less stress on the short living extension
Replace MQTT by HTTP (PUT and GET with long pollling (HTTP PUT shouldn't be slower than MQTT pub)
- We then could keep track of the states withing the HTTP server
- We can draw graphs there as well
- And we could add a control panel with reset, ... there
