How do I simulate file upload using Playwright?


To test file uploading with @playwright/test, use the setInputFiles() method. First, select the input element with the type "file" and pass the file path(s) in an array.

For a single file:

await page.getByLabel('Upload file').setInputFiles('myfile.pdf');

For multiple files:

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

To remove selected files, pass an empty array:

await page.getByLabel('Upload file').setInputFiles([]);

If the input element is created dynamically, handle the page.on('filechooser') event or use a waiting method:

const fileChooserPromise = page.waitForEvent('filechooser');
await page.getByLabel('Upload file').click();
const fileChooser = await fileChooserPromise;
await fileChooser.setFiles('myfile.pdf');

You can also upload a buffer from memory:

await page.getByLabel('Upload file').setInputFiles({
  name: 'file.txt',
  mimeType: 'text/plain',
  buffer: Buffer.from('this is test')

This offers flexibility when testing various upload scenarios. With these methods, @playwright/test makes it easy to automate file uploading in your tests.
