How to capture JavaScript exception for automation test in Java-selenium on LambdaTest

Prerequisites

1. Install and set environment variable for java.
   • Windows - https://www.oracle.com/java/technologies/downloads/
   • Linux - sudo apt-get install openjdk-8-jre
   • MacOS - Java should already be present on Mac OS X by default. 2 Install and set environment varibale for Maven.
   • Windows - https://maven.apache.org/install.html
   • Linux/ MacOS - Homebrew (Easier)

    install maven
   

Capturing and printing JS exceptions:

        DevTools devTools = ((HasDevTools) driver).getDevTools();
        devTools.createSession();

        List<JavascriptException> jsExceptionsList = new ArrayList<>();
        Consumer<JavascriptException> addEntry = jsExceptionsList::add;
        devTools.getDomains().events().addJavascriptExceptionListener(addEntry);

        //print
        for (JavascriptException jsException : jsExceptionsList) {
            System.out.println("My JS exception message: " + jsException.getMessage());
            System.out.println("My JS exception system: " + jsException.getSystemInformation());
            jsException.printStackTrace();
            success = true;
        }

Run your First Test

1. Clone the Java-Selenium-Sample repository.

git clone https://github.com/LambdaTest/java-selenium-sample.git

2. Next get into Java-Selenium-Sample folder, and import Lamabdatest Credentials. You can get these from lambdatest automation dashboard.

   For Linux/macOS::

export LT_USERNAME="YOUR_USERNAME"
export LT_ACCESS_KEY="YOUR ACCESS KEY"

For Windows:

set LT_USERNAME="YOUR_USERNAME"
set LT_ACCESS_KEY="YOUR ACCESS KEY"

Step 3. You may also want to run the command below to check for outdated dependencies. Please be sure to verify and review updates before editing your pom.xml file as they may not be compatible with your code.

 mvn versions:display-dependency-updates

Step 4. Run single test.

mvn clean install exec:java -Dexec.mainClass="com.lambdatest.JavaScriptExceptions" -Dexec.classpathScope=test -e
