How to capture performance logs in Java-TestNG using CDP on LambdaTest

Environment Setup

1. Global Dependencies
   • Install Maven
   • Or Install Maven with Homebrew (Easier)

   $ install maven
   

2. Project Dependencies
   • checkout the repository
   • Check that packages are available

   $ cd Java-TestNG-Selenium
   

   • You may also want to run the command below to check for outdated dependencies.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

LambdaTest Authentication Credentials: Make sure you have your LambdaTest credentials with you to run test automation scripts with Jest on LambdaTest Selenium Grid. You can obtain these credentials from the LambdaTest Automation Dashboard or through LambdaTest Profile.

Set LambdaTest Username and Access Key in environment variables.

• 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"
  

View performance metrics

To view performance metrics, the following code can be used:

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

devTools.send(Performance.enable(Optional.empty()));
List<Metric> metricList = devTools.send(Performance.getMetrics());


for (Metric m : metricList) {
   System.out.println(m.getName() + " = " + m.getValue());
   success = true;
}

Running Tests

To run single test
    $ mvn test -D suite=single.xml -Dtestng.dtd.http=true
