Viewing Evidence Packs

Using Claude Code, Cursor, or another coding agent? Paste this into your prompt to run cross-browser and real-device tests, debug sessions, and wire up CI on the TestMu AI cloud:

A sealed pack opens in the hosted viewer. When you serve a pack with kane-cli evidence serve, the server is local only and nothing is uploaded, because the viewer page reads the pack bytes from your machine.

After a run

After a run in an interactive terminal, kane-cli offers to open the pack:

View evidence in browser? (y/N)

Accepting starts a local server and opens the hosted viewer pointed at your pack. In agent or non-interactive runs there is no prompt. kane-cli prints a hint line to stderr instead:

evidence: view locally with `kane-cli evidence serve <path-to-pack>`

`kane-cli evidence serve`

Serves one or more sealed packs to the hosted viewer:

kane-cli evidence serve .testmuai/evidence/<execution_id>.evidence

serving 1 pack on http://127.0.0.1:54321
<execution_id>.evidence
  pack    http://127.0.0.1:54321/<token>/<execution_id>.evidence
  viewer  https://evidence.lambdatest.com/?pack=http%3A%2F%2F127.0.0.1%3A54321%2F...
press Ctrl-C to stop

Open the viewer URL in your browser.

Flag	Description	Default
`--port <n>`	Pin the local port	ephemeral
`--viewer-url <base>`	Override the hosted viewer base URL	environment’s viewer
`--env <name>`	Environment (`prod` or `stage`)	active profile’s env

serve accepts sealed .evidence files only. A live, unsealed pack directory is rejected. Exit codes: 0 after a clean Ctrl-C shutdown, 2 for any bad input or a port that cannot be bound.

The server binds to 127.0.0.1 only and uses a random per-instance token in the URL path. Nothing is uploaded anywhere.

The hosted viewer

The viewer at https://evidence.lambdatest.com is a static page that opens packs three ways:

a ?pack=<url> query parameter, which is what evidence serve and the post-run offer construct for you,
drag and drop of a .evidence file,
a file picker.

It remembers your recently opened packs, and reads packs with ranged requests, so even a very large pack opens after fetching only a few kilobytes.
