fix: run-tests now fails a run when a fixture's one-time setup or teardown throws - #3027
Merged

Conversation
The skill said XmlPath is an empty string when no XML was saved, but every response that saves none sends null: all producers pass null and the response serializer keeps nulls. An agent that follows the docs and checks for an empty string misses the no-XML case (#3025).
When a fixture's OneTimeTearDown throws, or a setup fixture's does, Unity marks that suite Failed while its tests keep Passed. run-tests judged the run from the tests alone, so it reported Status Passed and Success true, dropped the exception message, and saved no XML (#3026). - List the deepest Failed suite that has no failed child suite and no failed test in a new FailedSuites field, with its message and source location, and report the run as Failed with HasFailures true - Save the XML for such a run, with a <failure> on the suite element and a Failed run result - Move the skill's XML section to references/xml-results.md so SKILL.md stays under the 8,000-byte cap
…iled tests The previous rule listed only the deepest Failed suite with no failed child suite and no failed test. It dropped a fixture whose OneTimeTearDown threw while one of its tests also failed, and a setup fixture whose OneTimeTearDown threw above a failing fixture, so an agent could not see the teardown error until the test failure was fixed. - NUnit records a one-time setup or teardown error on the suite's own result state at the (SetUp) or (TearDown) site and rolls failures into ancestors at the (Child) site, so that site now decides. - The old structural rule stays as the fallback for a Failed suite with neither site and nothing Failed beneath it, such as a cancelled one; without it a cancelled run whose executed tests all passed reports success. - A OneTimeSetUp failure now lists the suite too. It is the only entry carrying the throw's file and line, since its tests only get "OneTimeSetUp: ..." messages. The test fake now carries the result state strings Unity's NUnit produces. The skill names OneTimeSetUp in the FailedSuites bullet and no longer says a throwing fixture's tests stay passed; the generated copies are regenerated.

Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughRun-tests now identifies suite-level failures, includes failed-suite details in its response, and saves NUnit XML when suite failures occur. The XML exporter includes suite failure messages and marks the overall result as failed when the root suite fails. The run-tests documentation describes these response and XML behaviors.

| # run-tests XML result file | |||
|
|
|||
| When a test or suite fails or a test ends inconclusive, run-tests saves NUnit XML results to `{project_root}/.uloop/outputs/TestResults/<timestamp>.xml` and returns the path in `XmlPath`. A run in which every test passed or was skipped saves no XML, and `XmlPath` is `null`. | |||

Document the generated XML filename accurately.
NUnitXmlResultExporter.CreateResultFileName saves <timestamp>_<GUID>.xml. All three references instead show <timestamp>.xml, which can lead readers to look for a nonexistent file.

Summary
[OneTimeTearDown]throws), even if every test passed.FailedSuitesfield, also when some of its tests failed too, and the NUnit XML is saved with the error on the fixture's element.XmlPathasnullwhen no XML was saved, matching what the response sends.User Impact
Status: Passed/Success: true. The error appeared nowhere and no XML was saved, so an agent could accept a broken test run as green.Status: Failed/Success: false/HasFailures: true,FailedSuitesnames each failing fixture with its message and source location, andXmlPathpoints to an XML file whose<test-suite>element carries the error.[OneTimeSetUp]throws is listed too. Its tests only carry anOneTimeSetUp: ...message, so the fixture entry is the one that points at the throwing line.XmlPathwith an empty string, as the skill used to say, now know it isnullwhen no XML was saved.Changes
<failure>with the message and stack trace on failed<test-suite>elements, and mark the XML runFailedwhen the root isFailed.references/xml-results.mdto keepSKILL.mdunder the 8,000-byte limit, and regenerate the skill copies.Verification
uloop run-tests --filter-type regex --filter-value RunTests→ 193 passed, 0 failed. Removing the fallback for suites with nothing failed beneath them makes the cancelled-run test fail.OneTimeTearDownthrows, each with a passing test:Status: Failed,Success: false,HasFailures: true, exit code 1, and both suites listed inFailedSuiteswith their messages and the throwing lines.OneTimeTearDownalso throws, a setup fixture whoseOneTimeTearDownthrows above a fixture with a failing test, and a fixture whoseOneTimeSetUpthrows: each of the three suites listed exactly once with the throwing line, no ancestor suite listed, and the failing tests listed inFailedTests.<test-suite>element.check-skill-size,sync-tool-docs --check, the file length check, and the code complexity check pass locally.Closes #3025
