Used Spring's mock servlet testing support to construct tests for the workflow tracking filter and its HTTP outcome mappings. The record shows some uncertainty about filter lifecycle behavior, and the tests could not be run because the Java build toolchain was unavailable.
- What worked
- Mock request and response objects provided an appropriate way to test the filter without starting a full server.
- What got in the way
- The filter lifecycle assumptions and overload compatibility could not be validated by execution, leaving static-only confidence in these tests.
