Introduction

[SOUND] Hi there, I'm Chris and 0:00 I teach Java here at tree house. 0:03 What we're going to talk about today is a unit testing a web application that was 0:08 developed using the Spring Framework. 0:11 If you've spent time in our library you may have watched Craig talk about unit 0:14 testing with JUnit that's a great place to start if you're new to unit testing 0:18 In general, you'll want to unit test an application to ensure that it does indeed 0:23 do what you intend it to do. 0:28 You can use unit test to check for boundary cases or 0:30 special cases, as well as testing that normal functionality is working. 0:33 In general, if you aren't incorporating unit tests, 0:37 you haven't done your due diligence in creating reliable software. 0:40 As far as spring is concerned you may have also spent time with me learning 0:46 about the power of the spring framework in developing scalable web applications 0:50 in our library we've used the Model View Controller pattern 0:55 to nicely separate the functionality into distinct layers. 0:58 It is especially important when writing applications in bigger frameworks like 1:02 spring, that you incorporate unit tests to ensure as much as possible, 1:06 that your code is functioning as intended. 1:11 Fortunately, spring provides a whole testing library that allows you to test 1:14 each one of these layers and includes ways for 1:18 you to incorporate the mocking of parts that don't need to be present 1:21 in their full production forms for purposes of testing. 1:25 Marking simply means faking certain functionality. 1:28 During this workshop, we’ll discuss how to test controllers, views, services and 1:32 DAOs as well as incorporate the marking of objects that are being tested directly. 1:37 All right with that said let's get to it. 1:43
