/*

This class is used to test the CLI commands of the Processing IDE.

It mostly exists to quickly run CLI commands without having to specify run configurations

or to manually run it on the command line.

In IntelliJ IDEA, it should display runnable arrows next to each test method.

Use this to quickly test the CLI commands.

The output will be displayed in the console after `Running CLI with arguments: ...`.

When developing on the CLI commands, feel free to add more test methods here.
