Unit testing on custom library

Technical Programming
1

I’m building a custom library for our team, to make it easier to port over our common classes across various projects, and I’m encountering a small issue.

I’ve been doing unit testing via Mockito for a while now, and I want to port this unit testing to my custom library. It runs correctly in one project (PurpleSwerve), but when I run it in our library project (PurpleLib) it runs, but VSCode doesn’t show the test results/status, i.e, I don’t get a green check or red X to show pass/fail. Namely I would like to port over LEDSubsystemTest.java from PurpleSwerve to PurpleLib.

Note, I add HAL.initialize(100, 0); when I copy over that LED test to the PurpleLib project.

Tests need to be in a Java folder. So src/test/java/utils/… rather then src/test/utils like you have.

Hmm, I still have an issue after moving the tests to the proper location. The JSONObjectTest works fine, but LEDSubsystemTest doesn’t.

I get the following error:

java.io.IOException: wpiHaljni could not be loaded from path or an embedded resource.
	attempted to load for platform /linux/x86-64/
Last Load Error: 
no wpiHaljni in java.library.path: [/home/vignesh/Documents/source/PurpleLib/build/jni/release]

I’ve pushed my changes.

Figured it out, I was missing a few things in the dependencies section in my build.gradle and I didn’t run “Test robot code” from the VSCode command palette first, to get it to bring in the JNI libraries.

  nativeDebug wpi.java.deps.wpilibJniDebug(wpi.platforms.desktop)
  nativeDebug wpi.java.vendor.jniDebug(wpi.platforms.desktop)
  simulationDebug wpi.sim.enableDebug()

  nativeRelease wpi.java.deps.wpilibJniRelease(wpi.platforms.desktop)
  nativeRelease wpi.java.vendor.jniRelease(wpi.platforms.desktop)
  simulationRelease wpi.sim.enableRelease()
