We use given_when_then or when_then BDD style syntax for test names (same elsewhere)

This is not the right syntax, see the suggestion for the syntax we require
| void given_simpleHelloWorldClass_when_compiledFromString_then_compilationSucceeds() { | |
| void givenSimpleHelloWorldClass_whenCompiledFromString_thenCompilationSucceeds() { |
|

| @Test | ||

Remove all the comments from the tests, the assertion messages and test layout should speak for itself

Extract a version number property (this is another mandatory guideline)

The alignment is still not correct here. Please review it visually and fix it.

I was also advised by the team that we have guidelines to not use comments to add explanations for the code. All the required explanations should be in the text. Can you please remove the comments and JavaDoc from the PR to address this, and move any comments that are important to note into the article text instead.
- rename test file to have UnitTest word at the end
