Prerequisites

---

Make sure you have the following set up before you start.

1. Create a TestMu AI account if you don't have one.
2. Get your Username and Access Key from the TestMu AI Dashboard.
3. Install the Java development environment (Java 11 recommended).
4. Install Maven. Download it from the official website or install it on Linux/MacOS using Homebrew.

Step 1: Clone the Sample Project

---

Pull the sample repo to your local machine and navigate into the project directory.

git clone https://github.com/LambdaTest/selenide-testng-sample
cd selenide-testng-sample

You may also want to run the command below to check for outdated dependencies.

mvn versions:display-dependency-updates

Step 2: Set Your Credentials

---

Add your TestMu AI credentials as environment variables so the test can authenticate with the grid.

Visit the TestMu AI Dashboard, navigate to the left sidebar, and select Credentials. Copy your Username and Access Key, then set them as environment variables:

macOS / Linux

export LT_USERNAME="undefined"
export LT_ACCESS_KEY="undefined"

Windows

set LT_USERNAME="undefined"
set LT_ACCESS_KEY="undefined"

Note

You can also mention your TestMu AI credentials in each of the config files located at selenide-testng-sample/src/test/resources/conf/.

Step 3: Configure Your Test Capabilities

---

Define the browser, version, and OS for your test run.

ChromeOptions browserOptions = new ChromeOptions();
        browserOptions.setPlatformName("Windows 10");
        browserOptions.setBrowserVersion("latest");

        HashMap<String, Object> ltOptions = new HashMap<String, Object>();
        ltOptions.put("build", "LambdaTestSampleApp");
        ltOptions.put("name", "LambdaTestJavaSample");
        ltOptions.put("network", true); // To enable network logs
        ltOptions.put("visual", true); // To enable step by step screenshot
        ltOptions.put("video", true); // To enable video recording
        ltOptions.put("console", true); // To capture console logs
        ltOptions.put("w3c", true);
        browserOptions.setCapability("LT:Options", ltOptions);

tip

Use the Capabilities Generator to auto-generate capabilities for any browser, version, and OS combination.

Below is the sample Selenide test used in this project:

        open("http://www.google.co.uk");

        $(By.name("q")).setValue("LambdaTest").pressEnter();

        sleep(2000);

        Assert.assertEquals(title(), "LambdaTest - Google Search");

        status = "passed";
    }

    @AfterMethod(alwaysRun = true)
    public void tearDown() throws Exception {
        driver.executeScript("lambda-status="+status);
        driver.quit();
    }

}

Step 4: Run the Test

---

Trigger the test from your terminal.

First, install the mandatory Selenium dependencies for Maven:

mvn compile

Then execute the tests:

Single Test

mvn test -P single

Parallel Tests

mvn test -P parallel

For parallel execution, the sample project includes a parallel.testng.xml that runs the test across multiple browsers simultaneously:

parallel.testng.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Parallel" thread-count="3" parallel="tests">
	<test name="SingleTestChrome">
    <parameter name="config" value="parallel.conf.json"/>
    <parameter name="environment" value="chrome"/>
    <classes>
      <class name="com.lambdatest.SingleTest"/>
    </classes>
	</test>

	<test name="SingleTestFirefox">
    <parameter name="config" value="parallel.conf.json"/>
    <parameter name="environment" value="firefox"/>
    <classes>
      <class name="com.lambdatest.SingleTest"/>
    </classes>
	</test>

	<test name="SingleTestSafari">
    <parameter name="config" value="parallel.conf.json"/>
    <parameter name="environment" value="safari"/>
    <classes>
      <class name="com.lambdatest.SingleTest"/>
    </classes>
	</test>
</suite>

parallel.config.json

{
  "server": "hub.lambdatest.com",
  "user": "YOUR_USERNAME",
  "key": "YOUR_ACCESS_KEY",

  "capabilities": {
    "build": "Java Selenide Parallel"
  },

  "environments": {
    "chrome": {
      "platformName": "Windows 10",
      "browserName": "chrome",
      "browserVersion": "latest"
    },
    "firefox": {
      "platformName": "Windows 10",
      "browserName": "firefox",
      "browserVersion": "latest"
    },
    "safari": {
      "platformName": "macOS Mojave",
      "browserName": "safari",
      "browserVersion": "latest"
    }
  }
}

Step 5: View Your Results

---

Check the Automation Dashboard to see exactly what happened during your test.

Visit the TestMu AI Automation Dashboard to see your test results. Each session includes:

• Video recording of the full test execution
• Screenshots captured at each step
• Console logs from the browser
• Network logs for every request and response
• Selenium command logs showing each driver action

Run Selenide Tests Using Agent Skills

---

Use AI coding assistants to generate and run Selenide tests with the TestMu AI Agent Skill.

The selenide-skill is part of TestMu AI Agent Skills - structured packages that teach AI coding assistants how to write production-grade test automation.

Install the skill:

git clone https://github.com/LambdaTest/agent-skills.git
cp -r agent-skills/selenide-skill .claude/skills/

# For Cursor / Copilot
cp -r agent-skills/selenide-skill .cursor/skills/

tip

Install all available framework skills at once by cloning the repository directly into your tool's skills directory (e.g., .claude/skills/, .cursor/skills/).
