[FEATURE REQUEST] Add support for Groovy/Spock test file patterns in neotest-java

[emont01]

I am trying to run some tests written in groovy (spockframework) using maven project (pom.xml) but just I discovered that test patterns [only support java]

I am trying to run tests written in Groovy using the Spock framework within a Maven project (with pom.xml) using neotest-java. However, I discovered that the current test file and class pattern matching only supports Java files with .java extensions.

Specifically, the patterns defined here only match Java test files:

local TEST_CLASS_PATTERNS = {
	"Test$",
	"Tests$",
	"Spec$",
	"IT$",
}

local JAVA_TEST_FILE_PATTERNS = {
	"Test%.java$",
	"Tests%.java$",
	"Spec%.java$",
	"IT%.java$",
}

return {
	TEST_CLASS_PATTERNS = TEST_CLASS_PATTERNS,
	JAVA_TEST_FILE_PATTERNS = JAVA_TEST_FILE_PATTERNS,
}

Since Spock tests are written in Groovy files (.groovy), these patterns do not detect them, causing tests not to be found or run.

Suggestion:

Extend the file pattern matching to include .groovy files alongside .java.

Alternatively, consider detecting test files based on their location inside src/test directories, regardless of extension. This enhancement would enable native support for Groovy/Spock tests in Maven projects without requiring extra changes.

I am happy to contribute or help test this feature if needed.

Thank you for considering this improvement!

Hi @emont01, thanks for suggesting this feature! 👋

I see a few things that should be implemented in order to support Groovy/Spock tests.

• Separating the JUnit plugin code from the new Spock code.
• Discovering tests with treesitter for groovy. Similar to here.
• Trigger a compilation for the codebase. I believe nvim-jdtls could still do the work as we are still on maven/gradle projects.
• Creating the command valid for selecting the tests to be run with the junit standalone jar.

I enumerate this points as not sure I can take this work any soon, but anyone can feel free to open a PR and I'd guide them.
