I created a last week showing you how to upload a file in WebdriverIO. However, one thing I didn't cover is how to upload a file when the input element is hidden which is the case in most modern websites.

Let's take a look at an example of how we can address that. I'm using online2pdf as our test site for this example.

Note: for this test site, the parent div containing the input was hidden so in order to make it interactable I had to make it visible for WebdriverIO by using browser.execute command (see code below).

const path = require('path');

describe('Upload File Hidden Input', () => {
  it('should be able to upload a file on hidden input', () => {
    // find your selectors
    const inputDiv = $('#div_file_box0');
    const input = $('#input_file0');
    const submitBtn = $('.convert_button');

    // store test file path
    const filePath = path.join(__dirname, '../data/chrome.png');

    // use browser.uploadFile to upload the test file
    const remoteFilePath = browser.uploadFile(filePath);

    // access the test page

    // change display to block from none for the hidden div
    browser.execute(function () {
      document.getElementById('div_file_box0').style.display = 'block';

    // wait for div to be displayed

    // set file path value in the input field
    submitBtn.click(); // click the submit button

    // temporary pause to see if the file got upload successfully

    // Add your assertion here

💎 This code is also available on GitHub for you to access and play around with.
