Multi Step Form

A ticket-ordering frontend app in React that:

1. Collects user input.
2. Uses correct input types for each field.
3. Validates the fields according to the validation rules provided below.
4. Preserves the state between steps.
5. Displays the collected information on the last step.
6. Includes unit tests for one module of your choice.
7. Makes the provided E2E tests pass.
8. Has the UI styled with design system scalability in mind. Use this Figma mockup as a reference.

Navigation elements

Each step of the form should also contain the "Submit" and "Back" buttons.

data-testid attributes are used to identify those elements.

The form steps

The inputs on the form steps have the following data-testid attributes:

Step 1

<form ...>
  <input data-testid="firstName" ... />
  <input data-testid="lastName" ... />
  <input data-testid="age" ... />
  <button data-testid="submit" />
</form>

Step 2

<form ...>
  <input data-testid="phone" ... />
  <input data-testid="email" ... />
  <button data-testid="submit" />
  <button data-testid="back" />
</form>

Step 3

<form ...>
  <input data-testid="seat" ... />
  <input data-testid="food" ... />
  <input data-testid="allergies" ... />
  <button data-testid="submit" />
  <button data-testid="back" />
</form>

Result

On the results page we see the values collected by the form. Each element containing the value has a data-testid field with the corresponding field name:

<div data-testid="<field name>">value</div>
<button data-testid="back" />
