HTML Report

--report html writes the run to one page that opens offline, so you can keep it as a CI artifact or attach it to a bug report.

$ uvx schemathesis run https://example.schemathesis.io/openapi.json \
    --report html
...
Reports:
  - HTML: schemathesis-report/html-20261011T121716Z/index.html

Pass --report-html-path ./html-report for a fixed directory.

• The verdict counts tests only; an amber line explains any other non-zero exit.
• Warnings that can make a pass meaningless, like 401 everywhere, come first.
• Each failure shows the response, a curl command and st replay.

In CI

Upload the report even when the job fails; that is the run you want to read.

- uses: schemathesis/action@v3
  with:
    schema: 'http://localhost:8080/openapi.json'
    args: '--report html'

- uses: actions/upload-artifact@v7
  if: always()
  with:
    name: schemathesis-html-report
    path: schemathesis-report/

With pytest

Tests that use the pytest plugin write the same page when schemathesis.toml enables it:

[reports.html]
enabled = true

Before Sharing

Schemathesis masks values whose keys look sensitive, but writes response bodies as the API returned them. Read the bodies before you post the page anywhere public.
