 1 | # How to capture performance logs in Java-TestNG using CDP on LambdaTest 
 2 | 
 3 | ### Environment Setup
 4 | 
 5 | 1. Global Dependencies
 6 |     * Install [Maven](https://maven.apache.org/install.html)
 7 |     * Or Install Maven with [Homebrew](http://brew.sh/) (Easier)
 8 |     ```
 9 |     $ install maven
10 |     ```
11 | 2. Project Dependencies
12 |     * checkout the repository
13 |     * Check that packages are available
14 |     ```
15 |     $ cd Java-TestNG-Selenium
16 |     ```
17 |     * You may also want to run the command below to check for outdated dependencies.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.
18 |     ```
19 |     $ mvn versions:display-dependency-updates
20 |     ```
21 | 
22 | **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](https://automation.lambdatest.com/) or through [LambdaTest Profile](https://accounts.lambdatest.com/detail/profile).
23 | 
24 | Set LambdaTest Username and Access Key in environment variables.
25 | 
26 | * For Linux/macOS:
27 |    ```
28 |    $ export LT_USERNAME="YOUR_USERNAME"
29 |    $ export LT_ACCESS_KEY="YOUR ACCESS KEY"
30 |    ```
31 | 
32 | * For Windows:
33 |    ```
34 |    $ set LT_USERNAME="YOUR_USERNAME"
35 |    $ set LT_ACCESS_KEY="YOUR ACCESS KEY"
36 |    ```
37 | ### View performance metrics
38 | To view performance metrics, the following code can be used:
39 | ```java
40 | DevTools devTools = ((HasDevTools) driver).getDevTools();
41 | devTools.createSession();
42 | 
43 | devTools.send(Performance.enable(Optional.empty()));
44 | List<Metric> metricList = devTools.send(Performance.getMetrics());
45 | 
46 | 
47 | for (Metric m : metricList) {
48 |    System.out.println(m.getName() + " = " + m.getValue());
49 |    success = true;
50 | }
51 | ```
52 | ### Running Tests
53 | 
54 | ```
55 | To run single test
56 |     $ mvn test -D suite=single.xml -Dtestng.dtd.http=true
57 | 
58 | ```
59 | ## About LambdaTest
