Upload file on a hidden input field – WebdriverIO

Table of Content

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).

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
    input.setValue(remoteFilePath);; // 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.

Understanding Equivalence Partitioning and Boundary Value Analysis in Software Testing

Software testing techniques help ensure software quality and reliability, by helping us select test cases intelligently from the collection of test cases, such that all test scenarios are covered.

Boundary Value Analysis and Equivalence Partitioning are two testing techniques that help testers select a subset of test cases that covers all important test scenarios, even under time and budget constraints. By testing all the equivalence classes and boundary values, testers can reduce the risk of releasing software with defects.
