-What is the overall purpose of testing your applications?
-
 Up until this point, you have been building tons of small projects in languages like HTML, CSS, JavaScript, and more. But how do you know if your projects are working correctly?
 
 One option is to do what is called manual testing. This is where a tester will go through each part of the application and test out all of the different features to make sure it works correctly. If any bugs are uncovered in the testing process, the tester will report those bugs back to the software team so they can be fixed.

-What is unit testing?
-
 As you design your applications, you will often have a series of small functions responsible for one thing. This is known as the "single responsibility principle." When you have a series of small functions, it is best to test these functions to ensure that everything works as expected. In this lecture, we will take a look at how to create a unit test using the popular Jest testing framework.
 
 In this example, we are going to create a function that is responsible for returning a newly formatted string:

 A real test scenario for functional testing would be a user login. A user should be able to log in to the application with their username and password. If successful, they should be able to access their account information. If there is an issue, then that error needs to be handled properly. When you are writing tests, you need to account for all types of success and failure scenarios.

+An example of non-functional testing would be to test the performance of your application under different network conditions. In a future lecture, you will learn more about performance testing.
 
 The reasons why functional testing is so important is because you want to identify bugs early on in your application. You also want to make sure that your application meets the requirements that were laid out at the beginning of the planning phase. Lastly, you want to ensure that your users have a good user experience. Users should not struggle to use your application or be blocked by broken features and system failures.

 End-to-end testing, or E2E for short, tests real-world scenarios from the user's perspective. Examples of E2E testing scenarios include testing the registration and login process or testing the checkout for an e-commerce site.
 
 To better understand how end-to-end testing works, let's take a look at a real-world example from the freeCodeCamp codebase. This example uses Playwright, a popular end-to-end testing framework developed by Microsoft.

-What is usability testing and what does the process look like?

 Usability testing is when you have real users interacting with the application to discover if there are any design, user experience, or functionality issues in the app. This type of testing is important because this feedback will help ensure that the application meets the needs of the users.
 
 The four common types of usability testing are explorative, comparative, assessment and validation testing.
