File upload testing is an important skill for students learning automation testing. Whether an application accepts resumes, profile photos, or PDF documents, Playwright makes it easy to automate these scenarios.

Why Is File Upload Testing Important?

File uploads are common in real-world applications, and testing them helps verify that users can submit valid files successfully. Playwright’s official documentation supports single-file uploads, multiple files, directory uploads, and in-memory file buffers. Its setInputFiles() method is available in the Locator API from version 1.14, while file-chooser handling was introduced earlier, before version 1.9.

How to Upload a File in Playwright

The simplest approach is to locate an HTML file input and use setInputFiles().

const { test, expect } = require('@playwright/test');
const path = require('path');

test('Upload a file', async ({ page }) => {
  await page.goto('https://example.com/upload');

  await page.getByLabel('Upload file')
    .setInputFiles(path.join(__dirname, 'myfile.pdf'));

  await expect(page.getByText('Upload successful')).toBeVisible();
});

The method accepts a file path and can also clear selected files by passing an empty array.

Upload Multiple Files

Students can practice multiple-file testing using an array of paths:

await page.getByLabel('Upload files').setInputFiles([
  path.join(__dirname, 'file1.txt'),
  path.join(__dirname, 'file2.txt')
]);

This is useful for testing document submission forms and bulk-upload features.

Handle Dynamic File Choosers

If the upload input appears only after clicking a button, Playwright provides waitForEvent('filechooser'):

const fileChooserPromise = page.waitForEvent('filechooser');

await page.getByText('Upload file').click();

const fileChooser = await fileChooserPromise;
await fileChooser.setFiles(path.join(__dirname, 'myfile.pdf'));

This approach is especially useful when the file input is created dynamically.
