 One of the main advantages of Codeception is that you don't have to decide on just *one* type of testing. You should have all three!
 And chances are, that you will (sooner or later) need all three. That's why Codeception consists of three so-called "suites":
-A "unit suite" for all unit tests, a "functional suite" for all functional tests, and an "acceptance suite" for all acceptance tests.

 What if you could check our application without running it on a server?
-That way you could see detailed exceptions on errors, have our tests run faster, and check the database against predictable and expected results. That's what functional tests are for.

 For functional tests, you emulate a web request (`$_GET` and `$_POST` variables) which returns the HTML response. Inside a test, you can make assertions about the response, and you can check if the data was successfully stored in the database.
 
-For functional tests, your application needs to be structured in order to run in a test environment. Codeception provides connectors to all popular PHP frameworks.
