When checking how checkboxes work, think about different situations to make sure they work well. Here are six test cases for a checkbox:

1. Basic Check/Uncheck:

   • Test Case: Click on the checkbox.

   • Expected Result: The checkbox should be checked. Click again, and it should be unchecked.

2. Check Multiple Boxes:

   • Test Case: Check multiple checkboxes.

   • Expected Result: All selected checkboxes should be checked simultaneously.

3. Uncheck Multiple Boxes:

   • Test Case: Check multiple checkboxes, then uncheck them.

   • Expected Result: All selected checkboxes should be unchecked simultaneously.

4. Verify Default State:

   • Test Case: Load the page with checkboxes.

   • Expected Result: Check if the checkboxes are in their default state (checked or unchecked as expected).

5. Checkbox Interaction with Other Elements:

   • Test Case: Check the checkbox and interact with other elements on the page (e.g., buttons, text fields).

   • Expected Result: Checkbox state changes should not interfere with the functionality of other elements.

6. Accessibility Check:

   • Test Case: Verify the checkbox using keyboard navigation (tab key) and check/uncheck using the space bar.

   • Expected Result: The checkbox should be accessible and functional using keyboard controls.

Don't forget to think about both good and bad situations when testing. This way, you can make sure the checkbox works as it should in different cases.
