⚠️ Breaking Changes - Migration Required

This release enforces stricter validation and removes support for deprecated YAML syntax. You must update your test files when upgrading.

Required Changes to Your YAML Files

1. Replace contains with regexp

# ❌ Old (no longer works)
logs:
  - logql: '{job="app"}'
    contains: ["error"]

# ✅ New
logs:
  - logql: '{job="app"}'
    regexp: "error"

logs:
  - logql: '{job="app"}'
-   contains: ["error"]
+   regexp: "error"

2. Remove spans array from traces

# ❌ Old (no longer works)
traces:
  - traceql: '{}'
    spans:
      - name: "GET /api"

# ✅ New
traces:
  - traceql: '{}'
    equals: "GET /api"

traces:
  - traceql: '{}'
-   spans:
-     - name: "GET /api"
+   equals: "GET /api"

3. Update profile flamebearers

# ❌ Old (no longer works)
profiles:
  - query: 'process_cpu:cpu:nanoseconds:cpu:nanoseconds'
    flamebearers:
      contains: "my-function"

# ✅ New
profiles:
  - query: 'process_cpu:cpu:nanoseconds:cpu:nanoseconds'
    flamebearers:
      equals: "my-function"

  - query: 'process_cpu:cpu:nanoseconds:cpu:nanoseconds'
    flamebearers:

What Changed

• Enforced validation for deprecated fields - Previously deprecated syntax now causes test failures
• Added comprehensive test coverage - 70+ unit tests ensure proper validation of all YAML configurations
• Stricter input validation - HTTP methods, schemes, status codes, and request bodies are now strictly validated

These changes improve the reliability and consistency of OATS test definitions.
