Example projects for Software Engineering course (A.A. 2017/18)

The repository contains projects examples for the SE course.

• beat contains an MVC example and JavaFX examples

Other folders are listed in lessons.

Lesson 1 - Testing

The purpose of this lecture is to understand the basics of software testing in practice. I provide a simple example of using JUnit outside of a Maven project (credits to JUnit quickstart). If you explore the chat project, you can see an example of testing the simple model of a chat system (with groups). I use Mockito for mocking object in case we have dependencies among them.

The source folders for this lesson are:

• junit-quickstart (see README inside);
• chat project.

Lesson 2 - Socket programming

The source folder is socket. See the README inside.

Lesson 3 - Java RMI

The source folder is rmi. See the README inside.

Lesson 4 - Graphical User Interfaces

The source folders are rmitter-view and fx-example.

We will proceed by introducing the Java Swing library by implementing the GUI for RMItter (our favorite Twitter implementation).

The code for the Swing implementation is here. The project specifies deib.ingsoft18.rmitter as dependency, so remember to:

$ cd rmi/rmitter
$ mvn install

Before compiling rmitter-view.

The graphical interface is far from being complete: it only displays every notification and allows a user to post. The interface does not allow to login, however, it allows to "connect" to someones account by providing its username and secret token. The secret token can be obtained by launching a RMItter client in its text-only version (as we did in the previous lesson).

As second example, we will introduce the JavaFX framework by implementing the fx-example project. The interface simply consists in one frame in which the user can switch between two different screens and can modify the state of the application (represented by some integers). The screens offer the possibility to take a snapshot of the current state. When a snapshot is taken, it is "persisted" in a new frame.

NOTE that the rmitter-view contains other implementations for RMItter's GUI:

• FXGui: uses the programmatic APIs of JavaFX;
• FXGuiCSS: shows how to remove style from implementation and put it into a separate file;
• FXMLGui: uses FXML to re-implement the same interface.
