Why Test?
Manual Testing

Software testing is the process of assessing the completeness and quality of computer software. Usually this is done by running a part of a system (like a web application) and comparing the actual behavior to the expected behavior.

One way to perform software testing is manual testing. Manual testing is a form of testing done by a human interacting with a system. With web apps, this might be clicking, dragging, and typing through a webpage. A list of actions and expected behaviors would be given. If the observed behavior doesn’t match the expected behavior, the application has an error.

Errors, like the ones you may have found in the provided web app, are also called bugs. A bug is an error, fault, or flaw in software that makes a system behave in unexpected ways. As you read in the last exercise, these unexpected behaviors can cause harm to users. Ideally testing catches bugs before they are sent to users.


The same application is provided. As a manual test engineer for this app, you have been provided some features to test. Manually test the web app by following the list provided:

  • Behavior 1: Run npm start in the terminal and reload the page. Scroll down and expect the webpage to start with a blank order.
  • Behavior 2: Type a name and click “Place Order”. Scroll down and expect “Deliver to:” to display the submitted name.
  • Behavior 3: A blank name will not overwrite the existing name.
  • Behavior 4: Select a cake type and place the order. Expect “Cake” to display the selected cake type.
  • Behavior 5: Check some fillings. Expect “Fillings” to display your selected fillings.
  • Behavior 6: Choose a stack size. Expect “Pancake Count:” to display the number equivalent to the stack size, e.g. “Double” is “2”.
