Playwright supports both Java and JavaScript, with the same core browser automation capabilities in each language. Choose Java when it fits your application stack and team, then pair it with a test framework such as JUnit or TestNG. Choose JavaScript or TypeScript when you want to use Node.js and, optionally, Playwright Test, which includes its own runner and test tooling.
The distinction matters: Playwright Java is a Java API, not JavaScript code translated into Java. A Java test can also execute JavaScript inside a browser page, but that page code runs in a different environment from the Java process.
Choose the language and test setup
Both bindings let you automate Chromium, Firefox and WebKit. The decision is usually about the host language, dependency management and test ecosystem—not a different set of basic browser capabilities.

How to install Playwright in Java
1. Add the Maven dependency
Playwright for Java is distributed as Maven modules. Add the current compatible version shown by the official Java guide to your project’s pom.xml; avoid copying a version from an old tutorial without checking it.
<dependency>
<groupId>com.microsoft.playwright</groupId>
<artifactId>playwright</artifactId>
<version>CURRENT_COMPATIBLE_VERSION</version>
</dependency>Replace CURRENT_COMPATIBLE_VERSION with the published version. The official getting-started example specifies Java 8 or higher.
2. Install the browser binaries
After resolving the Maven dependency, use the Java CLI to install Playwright’s browsers. The Java guide documents installing all default browsers, a selected browser, or browser system dependencies. Run the relevant install command documented for your project and operating system. Browser binaries are tied to Playwright releases, so rerun browser installation if a library upgrade leaves the expected browser unavailable.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problems3. Launch, navigate and close resources
This standalone Java flow creates Playwright, launches Chromium in headless mode, opens a page, navigates to a URL and closes browser resources:
import com.microsoft.playwright.Browser;
import com.microsoft.playwright.Page;
import com.microsoft.playwright.Playwright;
public class CapturePage {
public static void main(String[] args) {
try (Playwright playwright = Playwright.create()) {
Browser browser = playwright.chromium().launch();
Page page = browser.newPage();
page.navigate("https://playwright.dev/");
System.out.println(page.title());
browser.close();
}
}
}The try-with-resources block closes the Playwright instance even if the work inside it fails. Close the browser as well when the program is finished with it. To inspect the browser UI while developing, configure launch options with setHeadless(false):
Browser browser = playwright.chromium().launch(
new com.microsoft.playwright.BrowserType.LaunchOptions().setHeadless(false)
);Use playwright.firefox().launch() or playwright.webkit().launch() to launch the other supported engines. For test suites, put setup and cleanup in the lifecycle hooks provided by the JUnit or TestNG integration you choose rather than creating a browser separately for every assertion.

4. Use a Java test framework
The Java binding does not require a particular runner. Playwright’s language guidance identifies JUnit and TestNG as options. Choose the one already used by the project, then organize browser creation, test setup, assertions and cleanup using that framework’s conventions.
Can I use Playwright with JavaScript?
Yes. The JavaScript ecosystem offers both the lower-level Playwright browser library and Playwright Test. If you want the integrated runner and test tooling, start with Playwright Test. Its installer prompts for JavaScript or TypeScript, a test directory, an optional CI workflow and browser installation.
Start a Playwright Test project
- Install a supported Node.js release. The official guide currently lists Node.js 22.x, 24.x or 26.x; confirm the live requirement before setup because supported releases can change.
- In the project directory, run
npm init playwright@latest. - Answer the prompts for JavaScript or TypeScript, the test folder, CI workflow and browser installation.
- Write a test in the generated test directory and run it with the command generated for the project, commonly
npx playwright test.
A representative JavaScript test using the Playwright Test runner looks like this:
import { test, expect } from '@playwright/test';
test('Playwright home page has a title', async ({ page }) => {
await page.goto('https://playwright.dev/');
await expect(page).toHaveTitle(/Playwright/);
});The page fixture is managed by Playwright Test. The runner supplies test discovery, assertions and reporting, and can run tests in parallel or collect traces. For an existing project, use the official guide’s instructions for adding Playwright rather than assuming a new-project scaffold is required.
Use the lower-level Node.js library instead
If you need browser automation in a script rather than the Playwright Test runner, install the Playwright package with npm, install the desired browser binaries and use the library directly. The browser lifecycle is explicit in this example:
Recommended Free Tools
import { chromium } from 'playwright';
const browser = await chromium.launch();
try {
const page = await browser.newPage();
await page.goto('https://playwright.dev/');
console.log(await page.title());
} finally {
await browser.close();
}Use the package and import style that matches the project. The lower-level library does not turn a script into a Playwright Test suite; add @playwright/test when you want the dedicated runner and its integrated test features.
Run JavaScript from Playwright Java
A Java test can execute JavaScript in the page with Page.evaluate. The Java process is the host environment; the evaluated function runs in the browser page environment. Ordinary Java variables are not automatically available in the page, and page variables are not automatically Java objects.
String title = page.evaluate("() => document.title").toString();
System.out.println(title);For values coming from Java, use the evaluation argument supported by the Java API and return a result explicitly. For example, pass a string into a browser-side function rather than referring to a Java local variable from inside the function. Check the Java evaluation documentation for supported signatures and value conversion details. If an evaluated expression returns a promise or is asynchronous, Playwright waits for its completion before returning the result.
This feature is useful for reading or changing page state that the normal locator and interaction APIs do not expose directly. It does not mean that JavaScript is required to write the rest of a Java test.
Which browsers does Playwright support?
Playwright supports Chromium, Firefox and WebKit. It manages browser binaries corresponding to Playwright releases, which helps keep the automation library and browser builds compatible.
- Use Playwright-managed browsers for the standard setup; install them after adding the dependency and again when needed after upgrading Playwright.
- Select an engine through the language binding: for example,
playwright.chromium()in Java orchromiumin the Node.js library. - Use branded Chrome or Microsoft Edge through supported browser channels when that is a requirement. Playwright does not install those branded browsers by default, and organizational browser policies can limit automation.
See the browser management guide for Java browser installation and channel details.
Advanced: connect Java to a Node.js browser server
The Java API can connect to an existing browser server launched by Node.js using BrowserType.connect. The connecting and launching Playwright versions must match in major and minor numbers. Treat this as an interoperability path for a deliberate shared-browser architecture, not as a requirement for a normal Java setup. The Java BrowserType.connect API reference documents the connection API.

Keep the setup reliable and diagnose common failures
Browser executable is missing
Symptom: Playwright reports that an executable is missing or the browser cannot be launched. Cause: the browser binaries were not installed, or the project was upgraded to a Playwright release whose matching binaries are absent. Fix: rerun the browser installation command for that language and project, and make sure it installs the browser engine your code launches.

Browser launch fails on a machine or CI runner
Symptom: the browser exits immediately or reports missing system libraries. Cause: required operating-system dependencies are unavailable, or the environment restricts browser execution. Fix: follow the official browser installation instructions for the operating system and install the required system dependencies. In managed environments, check whether policy or sandbox restrictions permit browser automation.
Tests pass locally but fail in another browser
Symptom: a test succeeds in Chromium but fails in Firefox or WebKit. Cause: browser behavior or page timing may differ, or the test may rely on an engine-specific assumption. Fix: run the relevant test against each engine you support and use Playwright’s normal waiting and locator APIs rather than fixed delays where possible. The engine selection is explicit, so ensure the test configuration actually includes the intended browsers.
JavaScript evaluation returns the wrong value or times out
Symptom: an evaluation result is missing, unexpected or not ready. Cause: code is reading a host-language variable as though it existed in the page, or an asynchronous browser operation has not been represented as a returned promise. Fix: pass input through the supported evaluation argument, return the desired value, and make asynchronous page code return or await its promise.
Node.js project setup or imports fail
Symptom: an import cannot be resolved or the test command is unavailable. Cause: the package was not installed in the project, the code uses an import style inconsistent with its module configuration, or the test runner was not added. Fix: verify the package installation and use the command and module conventions generated by the Playwright initializer. Use the browser library for scripts and Playwright Test when the project needs its runner.
