                  <th>Column 1</th>
                  <th>Column 2</th>
                </tr>
              </thead>
              <tbody>
                <tr>
                  <td>
                    Row 1: Cell 1 <button class="btn btn-primary btn-success">Changed</button>
                  </td>
                  <td>
                    Row 1: Cell 2 <button class="btn btn-primary">Change</button>
                  </td>
                </tr>
                <tr>
                  <td>
                    Row 2: Cell 1 <button class="btn btn-primary">Change</button>
                  </td>
                  <td>

                </tr>
              </tbody>
            </table>

// The following DOM command chain is unwieldy.
// To avoid repeating it, let's use `.as()`!
cy.get('.as-table')
  .find('tbody>tr').first()
  .find('td').first()
  .find('button').as('firstBtn')

// To reference the alias we created, we place an
// @ in front of its name
cy.get('@firstBtn').click()

cy.get('@firstBtn')
  .should('have.class', 'btn-success')
  .and('contain', 'Changed')

// Alias the route to wait for its response

cy.server()
cy.route('GET', 'comments/*').as('getComment')

// we have code that gets a comment when
// the button is clicked in scripts.js
cy.get('.network-btn').click()

// https://on.cypress.io/wait
cy.wait('@getComment').its('status').should('eq', 200)
