Description

Feature request: it'd great if HTTP/2 frame flags can be configured to test edge cases,

  • e.g.
  transactions:
  - client-request:
      frames:
      - HEADERS:
          flags:
            END_HEADERS: true
            END_STREAM: false
      - DATA:
          flags:
            END_STREAM: true

For now, it's automatically set

Research direction

Start in local/src/core/http2.cc around lines 1510-1520, where frame flags are currently set automatically. Trace how the YAML transaction frame definitions are parsed, then support configurable HEADERS and DATA flags like those shown in the issue. Done means the requested flags can be specified per frame instead of always being selected automatically.
