What Does This Do

• Adds unit tests to increase patch coverage to 100% for:
  • datadog.trace.bootstrap.debugger.CapturedContext (captureExpressions path)
  • com.datadog.debugger.probe.LogProbe (captureExpressions handling)
• Tests added:
  • LogProbeCaptureExpressionsUndefinedTest: verifies that an undefined capture expression produces an EvaluationError with the correct expr and message.
  • CapturedContextCaptureExpressionsTest: verifies add/get behavior for captureExpressions and the freeze() behavior (serialization sets strValue and clears value) with a JsonSnapshotSerializer initialized.

Motivation

• Ensure full patch coverage and prevent regressions in:
  • Error reporting when capture expressions evaluate to UNDEFINED.
  • Safe freezing/serialization of captureExpressions in CapturedContext.
• Historically, gaps in tests around these paths could allow regressions where:
  • Undefined capture expressions fail to surface as errors in LogStatus.
  • CapturedContext.freeze() doesn’t exercise the captureExpressions branch or fails to serialize values properly without an initialized serializer.

Additional Notes

• No production code changes; test-only additions.
• The serializer is initialized in a @BeforeAll to avoid null serializer issues during freeze() and to validate strValue generation.
• No public documentation or configuration flags are impacted.
