Allure Integration

Trace-mode artifacts — the trace zip and each test's per-test screenshot and video — attach to an Allure report automatically, so you can open them straight from the report. See Trace Mode for how to enable trace mode and produce these artifacts.

When an Allure reporter is present, trace-mode artifacts attach to the Allure report automatically — no extra wiring:

• traceGranularity: 'test' — each test's trace.zip (application/zip, a download that opens in show-trace), screenshot (image/png, inline) and video (video/webm, inline) attach to that test's card. This is the granularity to use for a per-test Allure report.
• traceGranularity: 'session' / 'spec' — a session/spec-spanning trace is written to disk and enumerated in the artifacts manifest, but not attached to individual test cards: a session/spec trace is only finalized after all its tests have run, by which point their Allure cards are closed and there is no open test to attach to. To surface it anyway, post-process the manifest in your own onComplete hook.

Per-adapter support:

Adapter	Attach mechanism
WebdriverIO	First-class via @wdio/allure-reporter's addAttachment.
Selenium	Via allure-js-commons' attachment() — runtime-agnostic, attaches under any Allure runner adapter, gated on an active allure-js-commons runtime.
Nightwatch	Produce-only — files + manifest are written but not attached inline (no live Allure attach API).

Embedded trace viewer. Because the archive uses a portable, standard trace-viewer on-disk format, an Allure report's own embedded trace viewer (Allure ≥ 2.35) can open the attached trace.zip directly inside the report.

Report noise. In trace mode the capture takes a per-action takeScreenshot to build the timeline; Allure logs every WebDriver command as a step and a screenshot per takeScreenshot. Silence that flood with the reporter's own options — the trace / screenshot / video attachments are unaffected:

reporters: [
  ['allure', {
    outputDir: 'allure-results',
    disableWebdriverStepsReporting: true,
    disableWebdriverScreenshotsReporting: true
  }]
]
