@testmuai/playwright-bindings

Thin runtime for testmu-style Playwright tests in TypeScript/JavaScript. Companion to testmuai-playwright-bindings (Python).

Install

npm install @testmuai/playwright-bindings playwright

Usage

import testmu, { resolveVar, setVar } from "@testmuai/playwright-bindings";
import { expect } from "@playwright/test";

testmu.configure({
  build: "build-123",
  name: "Login Test",
  variables: { email: "[email protected]" },
  testParams: { BASE_URL: "https://example.com" },
});

testmu.test("Login flow", async (page) => {
  testmu.step("Navigate");
  await page.goto(await resolveVar("${BASE_URL}"));
  testmu.done();

  testmu.step("Fill credentials");
  await page.locator("#email").fill(await resolveVar("{{email}}"));
  testmu.done();
});

testmu.run();

Env vars

| Var | Purpose | | ------------------------------ | ---------------------------------------------------------------- | | TESTMU_RUN_TARGET | local (default) or cloud | | LT_USERNAME, LT_ACCESS_KEY | LambdaTest credentials (enables ATMS + vision) | | TESTMU_SMART | 1 enables vision/heal (validated at run() — requires LT creds) |
