WebdriverIO — Upload file on a hidden input

I created a post 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).

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.
