#2211:

  • updated/added unit tests
    • added AssemblyInitialize method to load all plugins, create output directories for (script) samples and initialize the MainForm
    • script code is now stored in test resource files
    • refactored unit tests
  • updated (script) samples
  • added Test.cmd
