![]() ![]() If no elements then return Integer.MIN_VALUE. * al the ArrayList to search for the largest element * finds and returns the largest integer in the ArrayList al Public static void reverseArrayList(ArrayList al) * So if al starts as when its finished the same memory location What that means is that you do not create a new I think it has to do with the fact that I'm using a machine running Ubuntu. I'm pretty sure that I have JUnit installed and configured, but something in the configuration is incorrect. Web-CAT will automatically extract your two files from the zip archive.I'm trying to run a JUnit test on some of my files. That you will need to create a *.zip file with your two Java files ( Account.java and AccountTest.java) in it. Follow the instructions to upload your files. To hand in your files, click on the Submit 1 public class DivideMultiply A method to get the current balance in the account. Similarly, the DivideMultiply class has two methods which let you divide (line 21) or multiply (line 14) a given number with the class variable.ĥ * Constructor to initialize our member variable.ġ2 * Add the value of 'a' to our current value.ġ9 * Subtract the value of 'a' from our current value. The following AddSubtract class has two methods one to add (line 14) and another to subtract (line 21). For example, if we were writing a unit test for a method named fooBar() then our unit test would be named testFooBar(). The traditional method namingĬonvention is the word 'test' followed by the name of the method being Each method should test the functional correctness of one annotation signals that the following method is a JUnit unit test. This method is run once before every unit test (see next section).Ģ.4. There is only one of these methods per JUnit test case. annotation is used for a method usually named setUp(). ![]() The corresponding JUnit test case would traditionally be named FooTest.Ģ.3. For example, if we were testing the class Foo, then The traditional naming convention forĪ JUnit test case is to append the word 'Test' to the name of the JavaĬlass being tested. Test CaseThe declaration of a JUnit test case is exactly The Before class is used for running a method to initialize variablesīefore every unit test, and the Test class is for creating unit tests.Ģ.2. The static Assert class contains all the JUnit asserts to use. In JUnit 4.4, three packages should be imported: More JUnit unit tests should be written for every source-code method. It is generally good practice to have a JUnit This section will guide you through JUnit 4 syntax. Test-Driven Development, which will be introduced in Lab 2. Most commonly used to test the functionality of individual methods.Įxperience with JUnit has been important in the development of These are usually in the form of a method. Units are the smallest module of functionality in a computer JUnit is a unit testing framework for the Java programming Understanding of what JUnit is used for, and be able to write some By the end of this lab, you should have a basic This lab is intended to present an introduction to the JUnitįramework.
