Introduction to Empty States Testing

Empty states are a crucial aspect of Web applications, as they provide users with feedback when there is no data to display. Testing empty states is essential to ensure that users have a seamless experience, even when there is no content to show. A well-designed empty state can help to reduce user frustration, improve engagement, and increase overall satisfaction.

Why Empty States Testing Matters

Empty states testing matters because it can significantly impact the user experience. When empty states are not handled properly, users may become frustrated, leading to a higher bounce rate and lower conversion rates. Common failures in empty states include:

• Not providing any feedback to the user
• Displaying a blank page or a generic error message
• Not providing any calls to action to help the user
• Not being accessible to users with disabilities

Some examples of empty states include:

• A search results page with no results
• A user profile page with no posts or activity
• A shopping cart with no items

What to Test

When testing empty states, there are several specific test cases to consider:

• Happy path scenarios:

+ Test that the empty state is displayed correctly when there is no data to show

+ Test that the empty state provides a clear and concise message to the user

+ Test that the empty state includes a call to action to help the user

• Error scenarios:

+ Test that the empty state is displayed correctly when there is an error loading the data

+ Test that the empty state provides a clear and concise error message to the user

+ Test that the empty state includes a call to action to help the user recover from the error

• Edge cases:

+ Test that the empty state is displayed correctly when the user has no permissions to access the data

+ Test that the empty state is displayed correctly when the data is still loading

+ Test that the empty state is displayed correctly when the user has reached the end of a list or pagination

• Accessibility considerations:

+ Test that the empty state is accessible to users with disabilities, including screen readers and keyboard navigation

+ Test that the empty state includes alternative text for images and other non-text content

+ Test that the empty state does not include any inaccessible elements, such as blinking or flashing content

Some specific test cases for empty states include:

1. Test that the empty state is displayed correctly when the user searches for a term with no results
2. Test that the empty state provides a clear and concise message to the user when there is no data to show
3. Test that the empty state includes a call to action to help the user when there is no data to show
4. Test that the empty state is displayed correctly when there is an error loading the data
5. Test that the empty state provides a clear and concise error message to the user when there is an error loading the data
6. Test that the empty state includes a call to action to help the user recover from the error when there is an error loading the data
7. Test that the empty state is accessible to users with disabilities, including screen readers and keyboard navigation
8. Test that the empty state includes alternative text for images and other non-text content
9. Test that the empty state does not include any inaccessible elements, such as blinking or flashing content
10. Test that the empty state is displayed correctly when the user has no permissions to access the data

Manual Testing Approach

To manually test empty states, follow these steps:

1. Identify the empty states in the application: Look for areas of the application where there may be no data to show, such as search results pages or user profile pages.
2. Test the happy path scenarios: Test that the empty state is displayed correctly when there is no data to show, and that it provides a clear and concise message to the user.
3. Test the error scenarios: Test that the empty state is displayed correctly when there is an error loading the data, and that it provides a clear and concise error message to the user.
4. Test the edge cases: Test that the empty state is displayed correctly when the user has no permissions to access the data, or when the data is still loading.
5. Test the accessibility considerations: Test that the empty state is accessible to users with disabilities, including screen readers and keyboard navigation.

Automated Testing Approach

To automate the testing of empty states, you can use tools such as Selenium or Cypress. These tools allow you to write automated tests that interact with the application just like a user would.

For example, you can use the following Selenium code to test that the empty state is displayed correctly when the user searches for a term with no results:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

# Set up the webdriver
driver = webdriver.Chrome()

# Navigate to the search page
driver.get("https://example.com/search")

# Enter a search term with no results
driver.find_element(By.ID, "search-term").send_keys("no results")
driver.find_element(By.ID, "search-button").click()

# Wait for the empty state to be displayed
WebDriverWait(driver, 10).until(
    EC.visibility_of_element_located((By.ID, "empty-state"))
)

# Verify that the empty state is displayed correctly
empty_state = driver.find_element(By.ID, "empty-state")
assert empty_state.text == "No results found"

# Clean up
driver.quit()

You can also use Playwright to automate the testing of empty states. For example:

const { test, expect } = require('@playwright/test');

test('empty state is displayed correctly', async ({ page }) => {
  // Navigate to the search page
  await page.goto('https://example.com/search');

  // Enter a search term with no results
  await page.fill('#search-term', 'no results');
  await page.click('#search-button');

  // Wait for the empty state to be displayed
  await page.waitForSelector('#empty-state');

  // Verify that the empty state is displayed correctly
  const emptyState = await page.$('#empty-state');
  expect(await emptyState.textContent()).toBe('No results found');
});

How SUSA Tests Empty States Autonomously

SUSA tests empty states autonomously using a combination of user personas and flow tracking. The curious persona tests the happy path scenarios, such as searching for a term with no results. The impatient persona tests the error scenarios, such as when there is an error loading the data. The elderly persona tests the accessibility considerations, such as screen reader compatibility.

The adversarial persona tests the edge cases, such as when the user has no permissions to access the data. The novice persona tests the calls to action, such as when the empty state includes a call to action to help the user.

SUSA also uses flow tracking to test the empty states in the context of the application's workflow. For example, SUSA can test that the empty state is displayed correctly when the user searches for a term with no results, and then test that the user can recover from the error by clicking on a call to action.

Overall, SUSA's autonomous testing of empty states helps to ensure that the application provides a seamless user experience, even when there is no data to show.
