Upload an existing file using Playwright Java
Let us first see how to upload an existing file using PW java.
We will upload a test file from our local machine to the below site
https://the-internet.herokuapp.com/upload
First we will choose a file and click ‘Upload’.
Inspect ‘Choose File’ button
There is a ‘setInputFiles’ method that we can use to set the input file
This method accepts 2 arguments – selector (the locator of ‘Choose File’ button in current case) and file name.
Let us write the first argument using css selector
Next, create a file having extention .pdf
Mention the relative path of the file as second argument
After setting the input file, let us give some wait time and than click ‘Upload’ button
The entire script looks like below:
Save and execute.
Observe below that the file gets uploaded
This is show we can upload the file using PW.

The code looks like
After selecting the file, we have to press the ‘Press’ button to upload the same
Save and execute.
Notice below that file gets uploaded and the content of the file is displayed
Code snippet (upload file)
package com.w2a.pwjava;
import java.nio.file.Paths;
import com.microsoft.playwright.Browser;
import com.microsoft.playwright.BrowserContext;
import com.microsoft.playwright.BrowserType;
import com.microsoft.playwright.Page;
import com.microsoft.playwright.Playwright;
public class UploadFilePW {
public static void main(String[] args) throws InterruptedException {
Playwright pw = Playwright.create();
Browser browser = pw.chromium().launch(new BrowserType.LaunchOptions().setHeadless(false));
BrowserContext browserContext = browser.newContext();
Page page = browserContext.newPage();
page.navigate("https://the-internet.herokuapp.com/upload");
//syntax-page.setInputFiles(selector, files);
page.setInputFiles("#file-upload", Paths.get("test.pdf"));
Thread.sleep(3000);
// Click Upload
page.locator("text = Upload").last().click();
}
}
