Playwright ≥ 1.48

Before 1.48, test.step records its direct caller as the step location, which would be this library. The integration is therefore left off there (steps: 'auto'): actions are still logged, without step markers. See Browser logging.

mergeTests exists in Playwright from 1.39. The mergeTests exported by this package throws a clear error on older versions.

Node.js

Node 18 is the minimum for the library. Note that Playwright itself raises its own floor over time: for example Playwright 1.30 runs on Node 14 and later, 1.45 needs Node 18, and recent releases need Node 20. Pick a Node version that satisfies both.

The package is built for Node 16 syntax and ships CommonJS (dist/*.js) and ESM (dist/*.mjs) with matching type declarations for each (.d.ts for require, .d.mts for import).

Operating systems and shells

• The libraries themselves are plain JavaScript and work on Linux, macOS and Windows.
• The curl output is for POSIX shells (bash, zsh, sh, Git Bash, WSL). It does not work as-is in PowerShell or cmd.exe.
• File paths (fileDir) and stack-location handling accept Windows paths, file:// URLs and frames without parentheses.

Reporters

The loggers write through console.log (or your sink) and Playwright's attachments, so they work with every reporter. The html reporter shows the browser-log attachment. Colours follow the environment and never appear in attachments or files. Details in Reporter & attachments.

What CI verifies

The repository's CI runs:

• type check, lint, unit tests, build, CJS and ESM smoke tests, and package checks (publint, @arethetypeswrong/cli);
• the end-to-end suite with Playwright 1.30 (Node 18), 1.39 and 1.48 (Node 20) and the latest release (Node 22), all on Chromium; the latest release also on Firefox and WebKit. Each is run against the sources and against the built package;
• a weekly job that lists public async methods of the latest Playwright that the browser logger does not know yet;
• an overhead benchmark (informational).

CI runs on Linux. Windows and macOS are not part of the matrix.
