Write some tests

[ctrueden]

We can use cram. For all tests, run with both versions of jgo.

• Execute Parsington 1+3
• Shortcuts
• Main class abbreviations with @
• FQCN main class
• No main class
• Repeated execution of same endpoint
• Consistency of cache directory trees
• Various flags (-u, -U, -m, -v)

I am writing some tests atm, and would love to know a real use case for --additional-endpoints and --additional-jars.

I noticed an issue where an additional jar was needed for Groovy, but it seems to not need it now as PATH=/c/Program\ Files/Java/jdk-17.0.2/bin/:$PATH jgo org.codehaus.groovy:groovy-groovysh:org.codehaus.groovy.tools.shell.Main drops me into a Groovy prompt.

I see #43 deprecated --additional-jars three (3) years ago - I could just remove that CLI arg so it doesn't need tests.

The main set of code not covered in #79 was the if main_class[0] == "@": branch in autocomplete_main_class. I couldnt quickly see how to trigger that.

I filed #86 to track the test reproducibility issue with unpinned versions. I am closing this issue, thanks to @jayvdb's nice work on #79. 🍻
