R018: testcase重复

To detect duplicate testcase names within a describe block, scan your .test.ets, .test.ts, or .test.js files to find repeated it() or @tc.name values that cause test execution ambiguity. The analysis reports only the first occurrence per duplicate group.

Duplicate it() names within the same describe block create unit test execution ambiguity because the runner cannot uniquely identify each case. Enforcing testcase uniqueness inside the describe scope ensures test runs execute without conflicts.

No, duplicate testcase detection applies only within the same describe block scope. It does not compare @tc.name or it() values across different files or across different describe blocks to prevent cross-scope false positives.

To fix duplicate testcase names found during static analysis, keep the first occurrence unchanged and append an Adapt{three-digit-number} suffix to later duplicates, ensuring you update the @tc.name values accordingly for unique identification.

Yes, the duplicate testcase detection rule works with ArkTS test files. It applies filename and scope constraints to scan .test.ets, .test.ts, and .test.js files where testcase uniqueness must be enforced.
