Testplane (ex-Hermione) is a battle-hardened framework for testing web apps at any scale, any browser and any platform.

🧑‍💻 Developer Friendly: Enjoy a hassle-free start with our installation wizard, TypeScript support, instant feedback via live test editing, advanced HTML-reporter, and smart features like auto-wait and retries.

📸 Visual Testing Redefined: Capture anything from specific details to whole pages, manage diffs with a streamlined UI, explore a variety of diff modes and let Testplane tackle flakiness.

🌐 Test Across Environments: Forget being tied to a couple of latest Chrome builds. Testplane goes beyond that, offering testing on real devices and broad automation protocol support, mirroring your users' actual environments.

📈 Scale Effortlessly: Run thousands of tests on a remote browser grid or benefit from ultra-fast local execution. Testplane offers sharding, parallel test execution, and isolated browser contexts.

⚡ Infinite Extensibility: Testplane offers a versatile plugin system with dozens of open-source plugins on GitHub, along with custom reporters, commands, and execution logic.

📦 Various Test Environments: With Testplane you can run tests not only in Node.js environment but also in the browser. It means you can run e2e/integration tests in Node.js and component/unit tests in browser.

Getting started

Note: if you prefer manual installation, you can run npm i -D testplane. Check out the Docs for details.

1. Use the CLI wizard to set up testplane and generate basic configuration:

   npm init testplane@latest new-testplane-project

   You may add -- --verbose argument to launch a tool in extra-questions mode, to pick custom package manager or install extra plugins.

2. Open the newly generated file testplane-tests/example.testplane.ts. We’ll modify the test to ensure the description includes expected text:

   describe("test", () => {
       it("example", async ({browser}) => {
           await browser.url("https://example.com/");
   
           const description = await browser.$("p");
   
           await expect(description).toHaveTextContaining("for use in illustrative examples in documents");
       });
   });

3. Launch GUI:

   npx testplane gui

4. Try running the test and watch it pass. Now, let's replace description text check with a visual assertion. Use the assertView command to carry out visual checks:

   - await expect(description).toHaveTextContaining("for use in illustrative examples in documents");
   + await description.assertView("description"); // "description" is just a name of the assertion

5. Run the test again. It will fail, because a reference image for the heading is missing. You can accept the diff and re-run the test, it will then pass.

Congratulations on writing your first Testplane test, which navigates to a page and executes a visual assertion. Dive into the Docs to discover more awesome features Testplane has to offer!

Rename from "Hermione"

This project was formerly known as "Hermione", but eventually some copyright and trademark issues surfaced, leading to the decision to rebrand. After some discussion, we settled on "Testplane" as the official new title. Considering this change as merely a rebranding, we've proceeded with the existing version count instead of starting anew. Thus, Testplane v8.x is a drop-in replacement for Hermione v8.x.
