TestPion 0.51.0

Save and export every output: every response and result now has the same down arrow at the right end of its bar, with Copy beside it and ▾ for the other formats, so anything TestPion shows can be kept as a file, safely. (What's new in 0.51)

Behaviour changes: what works differently (read before upgrading)

• One down arrow replaces the old per-view buttons. The run results' Export ▾, the response's Save response, the run timeline's Save as HTML, the MCP tool result's Copy result / Save result and the generated code's Copy are gone: the arrow at the right end of the same bar saves the same files (and more formats), and Copy sits beside it. A runs list's Export report… and the palette's Export Results now save the HTML report through the Save as dialog. (Save and export results)
• Saved logs are always redacted. The console, the application log, run reports, traces, the response's cURL, the flow timeline, data-run and matrix grids and the HTTP Debugger's HAR are masked when they are recorded, so they are saved and copied without secrets and have no Include secrets… (the Redacted mark's tooltip says why). Decoded JWTs, the terminal transcript and generated code (with Show secrets on) still hold their secrets: they are saved masked by default, and ▾ ▸ Include secrets… keeps them after you confirm.
• Ctrl+Shift+S saves the output you are in (rebindable as Download the focused output in Settings ▸ Keyboard).

Save and export every output

• One down arrow on every response and result, at the right end of its bar. It covers:
  • every tab of the REST/SOAP response: body (raw bytes as received, JSON pretty or minified, the table as CSV or TSV, HTML, XML, text, HAR), headers, cookies (also cookies.txt for curl -b), JWT, timeline (JSON, HAR with timings, Markdown), checks (JSON, JUnit, Markdown), stream, trace, server-sent events, history and cURL
  • GraphQL responses and subscriptions
  • the gRPC response, messages, metadata and trailers (each as JSON, metadata and trailers also as CSV, or everything in one JSON)
  • WebSocket, Socket.IO, MQTT and Kafka message logs
  • MCP tool results and generated code
  • run results (HTML report, JSON, JUnit, Markdown, CSV, ZIP of them all)
  • the flow run timeline (self-contained HTML), data-run and matrix grids, load results and the evaluation matrix
  • the console, the application log, the terminal, Problems and the HTTP Debugger session (HAR)
• How it works:
  • Click saves the default format (or the one you chose last on that kind of output), ▾ chooses another or Copy as another text format, and Copy sits beside it.
  • Files are saved through the OS Save as dialog, in the folder you last used for that kind of output in the workspace, with names such as GET-patients-2026-10-17-1405-200.json; then a message offers Show in folder and Open. The browser version downloads them (up to 100 MB).
  • Ctrl+Shift+S, the palette's Download Output… and File ▸ Download Output… work too.
• Secrets: log-like outputs are saved redacted by default, with a Redacted mark; Include secrets… (confirmed, for that one file) is offered only where the data still holds the secrets. Response bodies are saved as they are, with a notice when one looks like it holds a credential or comes from a production environment.
• Big outputs: big bodies (a 50 MB body is re-indented as it is read) and long grids (a 10,000-row data run) are streamed from disk into the file, never through the window. Saves over 5 MB show progress with Cancel, and a cancelled or failed save leaves no half-written file (it is written as .part and renamed).
• Safe files: CSV files guard against spreadsheet formula injection, and file names are safe on every OS (Windows reserved names such as CON or NUL, and invisible direction-changing characters, are taken care of).
• Not yet: --out / --format on every CLI result command, MCP tools that save results to a file, and a down arrow on History, Traces, AI results, Git diffs, lint reports, charts and monitors come in a later release.

Fixes

• HTTP Debugger: Export as HAR… saves through the Save as dialog again. It called a backend method that did not exist, so it always fell back to a browser download.
• JSON tree toolbar: Expand all is no longer cut off, and the JSONPath filter is no longer squeezed against the hint. Expand and collapse are now icon buttons, and the hint moved behind an ⓘ.
