Support path-based test references in scenario files - #994
Conversation
Add an optional 'path' field on TestRunModel, mutually exclusive with 'test_name', resolved relative to the scenario file's own directory. When set, _prepare_tdef loads that file directly instead of doing a name lookup against test_mapping, with the same scenario-level override merging test_name already supports.

Field(min_length=1) rejects path="" at validation time instead of letting it through as a truthy-looking value that would otherwise resolve to the scenario file's own directory. Signed-off-by: shreyaskommuri <shreyaskommuri@gmail.com>

1006-1032: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winExercise the public scenario parser in the end-to-end test.
At Lines 1027-1030, the test manually validates the TOML and calls private
_prepare_tdef(). This verifies the helper and the model, but not the parser's public scenario-loading flow. If this test must provide end-to-end coverage, use the public parser entry point and assert the resulting scenario test. Otherwise, rename the test to indicate helper-level coverage.🤖 Prompt for AI Agents

@podkidyshev the empty-path issue from CodeRabbit is resolved, min_length=1 pushed and confirmed rejecting "" while still allowing None/real paths (see reply on the review thread above), plus a regression test. All CI green on the latest commit. Let me know if there's anything else you'd like changed. |
- 'test_template_name' must not be set if 'test_name' or 'path' is set now checks `is not None` instead of truthiness, so an explicit empty string no longer slips past the mutual-exclusion check. - test_empty_path_is_rejected and the new empty-test_template_name test pass their match pattern directly to pytest.raises instead of a separate exc_info.match() call. - test_full_scenario_toml_with_path_reference now calls the public TestScenarioParser.parse() instead of the private _prepare_tdef(), exercising the actual end-to-end scenario-parsing path. Signed-off-by: shreyaskommuri <shreyaskommuri@gmail.com>
The top-level Parser.parse() catches TestScenarioParsingError and exits without printing the exception itself, relying on the raiser having already called logging.error(). The path-reference branch in _prepare_tdef skipped that, so a missing referenced file failed with no error message at all in run/dry-run, just an immediate silent exit. Every other raise of this exception in the file already follows the log-then-raise pattern; this one now matches. Also: removed a redundant inline comment on the elif branch, and applied ruff's PLR5501 suggestion (elif instead of nested else/if) in the validator, which CodeRabbit flagged in a review that failed to post due to a transient GitHub outage on their end.

Summary
pathfield onTestRunModel, an alternative totest_namefor referencing a test in a scenario file, resolved relative to the scenario file's own directory (confirmed shape in Support relative-path test references and lazy-load only referenced test/hook tomls #985).test_nameandpathare mutually exclusive, same rulestest_namealready has withtest_template_name.TestScenarioParser._prepare_tdefgets a new branch: whenpathis set, it loads that toml file directly instead of doing a name lookup againsttest_mapping, then merges scenario-level overrides the same way thetest_namebranch already does.TestScenarioParsingErrorif the resolved path does not exist.--tests-dir/hooks when a scenario's tests are all path-referenced) depends on this one and is not included here, keeping this PR small and reviewable on its own.test_nameand fully-inline (test_template_name+name+description) scenarios are unaffected.Test Plan
7 new tests in
tests/test_test_scenario.py(TestPathReference), covering:path/test_namemutual exclusion,path/test_template_namemutual exclusion, relative-path resolution against the scenario file's directory, scenario-level override merging over the referenced file, a missing-file error, and a full scenario TOML parsed end to end with apathreference.Also updated the wording of two pre-existing validation error messages (in
models/scenario.py) that referenced onlytest_name, so they stay accurate now thatpathis a second way to satisfy the same requirement. Updated the two existing tests intests/test_test_scenario.pythat asserted on the old wording.Additional Notes
Design confirmed in #985 before writing any code, per
CONTRIBUTING.md's "communicate with the main developers before starting work." Not touching the eager-loading behavior itself, sweeping, or anything unrelated, this PR is purely additive.
