Playwright's bundled Chromium download relies on apt-get and sudo, which fails on NixOS and pure-Nix hosts. This Skill provides a self-contained Nix setup so an existing Playwright e2e suite can run locally without modifying GitHub Actions CI.
tests/shell.nix: Resolves a pinned nixpkgs-latest input from the parent flake lock and exposes playwright-driver.browsers via PLAYWRIGHT_BROWSERS_PATH.nixpkgs-latest pin so the Playwright browser revision updates on its own cadence, separate from the main nixpkgs.e2e target that enters the nix-shell, installs npm dependencies if missing, and runs the test suite.tests/ and needs npm test to work locally without apt-based browser installation.Set up my existing Playwright e2e tests to run locally on NixOS using a Nix shell and a justfile recipe.

Create a tests/shell.nix that imports a pinned nixpkgs and sets PLAYWRIGHT_BROWSERS_PATH to pkgs.playwright-driver.browsers with PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1. Then run the suite inside nix-shell, since npx playwright install --with-deps does not work on NixOS.
This error occurs when the pkgs.playwright-driver version drifts from the playwright version in tests/package.json. Fix it by running nix flake update nixpkgs-latest, matching the package.json version to the new driver, and regenerating the lockfile with npm install.
No, GitHub Actions CI is left untouched because apt-provided Chromium on Ubuntu runners is cheaper than a Nix devshell. This setup targets local runs and Nix-based CI systems like Vira only.
Add an independent flake input such as inputs.nixpkgs-latest.url = "github:nixos/nixpkgs/nixpkgs-unstable". The tests/shell.nix then reads the parent flake.lock to resolve that pin without needing a flake context.
No, this pattern assumes a project already has a Playwright e2e suite, typically under tests/. It only provides the Nix shell environment and justfile entry to run that suite locally on Nix-based systems.
