Add file attribute to <testcase> elements for CI/CD tool compatibility

[piripi-heidi]

🤔 What's the problem you're trying to solve?

Many CI/CD analytics tools (e.g., Trunk Analytics, Codecov) require a file attribute on elements to map test results back to source files. This enables features like:
Code owner matching for test failures
File-level test coverage visualization
Linking test results to specific feature files
Currently, the JUnit XML output only includes classname, name, and time on testcase elements:

Tools like Trunk Analytics report warnings like:

report has test cases with missing file or filepath

✨ What's your proposed solution?

add the file attribute using the already-available pickle.uri:
<testcase classname="Login Feature" file="features/login.feature" name="User can login" time="5.2">
This is a minimal change (~3 lines of code):
makeReport.ts:

` interface ReportTestCase {
classname: string
name: string
time: number

• file: string
  failure?: ReportFailure
  output: string
  }`

` return {
classname: testClassName ?? lineage.feature?.name ?? pickle.uri,
name: testNamingStrategy.reduce(lineage, pickle),
time: durationToSeconds(query.findTestCaseDurationBy(testCaseStarted)),

•    file: pickle.uri,
     failure: makeFailure(query, testCaseStarted),`
  

index.ts:

` const testcaseElement = builder.ele('testcase', {
classname: testCase.classname,
name: testCase.name,
time: testCase.time,

•        file: testCase.file,
       })`
  

⛏ Have you considered any alternatives or workarounds?

Alternatives Considered
Post-processing the XML to add file paths from the JSON report (current workaround)
Using classname to store the file path (loses the feature name information)

📚 Any additional context?

Many CI/CD analytics tools (e.g., Trunk Analytics, Codecov) require a file attribute on elements to map test results back to source files.

Could you provide some references for this? Preferably in the form of documentation from Codecov or Trunk Analytics or examples from a platform (Jest, PyTest, ect) that produces JUnit XML with file names? But source code would be acceptable too.

At first reading I'm a bit skeptical because Trunks own examples don't include the file name:

Ah. I needed to look one page further

• https://trunk.io/testing/jest
• https://trunk.io/testing/mocha
• https://trunk.io/testing/pytest

I see you already made a PR, but you've closed it?

Happy to raise another PR, closed because it wasn't ready yet.

Thank you, that would be most welcome. Please do put it behind a feature toggle.
