Tutorial 2 – Create and Execute First Playwright-Java Test
What you will Learn:
Create first playwright java test
Execute test
Resolve exception
Optimising the code
Code snippets
Create first playwright java test
Create a package under src/test/java and create a simple java class
Create a simple @Test and import the required packages. Create an object of Playwright and make sure there are no compile time errors
If there is no error, we can proceed further.
Below code is self-explanatory wherein we are creating the chromium browser type object (line#13) and then launching the chromium browser (line#14).
We then create a new page on this launched browser (line#15) and then navigate to a webpage (line#16). Finally we print the title of the page (line#17)
Execute Test
Save and run the junit test. The below exception might be thrown
java.lang.NoClassDefFoundError: org/junit/platform/engine/EngineExecutionListener
Resolve exception
To resolve this exception, we need to add the ‘junit-jupiter-engine’ dependency in xml
https://mvnrepository.com/artifact/org.junit.jupiter/junit-jupiter-engine/5.9.0
Copy this and add this dependency
Save xml.
Execute the junit test once more.
Notice that, there is no exception this time. The page title gets printed
The page title (printed in the console) matches with the actual page title, see below

The junit test passes
Optimising the code
We can optimise the code by commenting lines#13 and 14. Append their respective methods in line#15 itself
Save and execute. The page title gets printed
Code snippet (without optimization)
package com.w2a.pwjava;
import org.junit.jupiter.api.Test;
import com.microsoft.playwright.Browser;
import com.microsoft.playwright.BrowserType;
import com.microsoft.playwright.Page;
import com.microsoft.playwright.Playwright;
public class PWTest {
@Test
public void PWFirstTest() {
Playwright pw = Playwright.create();
BrowserType browsertype = pw.chromium();
Browser browser = browsertype.launch();
Page page = browser.newPage();
page.navigate("https://www.way2automation.com/lifetime-membership-club/");
System.out.println(page.title());
}
}
Code snippet (with optimization)
package com.w2a.pwjava;
import org.junit.jupiter.api.Test;
import com.microsoft.playwright.Browser;
import com.microsoft.playwright.BrowserType;
import com.microsoft.playwright.Page;
import com.microsoft.playwright.Playwright;
public class PWTest {
@Test
public void PWFirstTest() {
Playwright pw = Playwright.create();
//BrowserType browsertype = pw.chromium();
//Browser browser = browsertype.launch();
Page page = pw.chromium().launch().newPage();
page.navigate("https://www.way2automation.com/lifetime-membership-club/");
System.out.println(page.title());
}
}
