Testplane

Fast, scalable and robust testing solution for the ever-evolving web landscape.

Total Downloads Latest Release License

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.

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 -- -y option to quickly set up a project using defaults.

  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");

        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:

    - 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!

Docs

The documentation is divided into several sections:

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. We've tailored Testplane v1 to be a drop-in replacement for Hermione v8.

Learn more about migration from Hermione to Testplane in the Docs.
