2 Software Architectures

3 Agile Methods

Overview

Agile development is a set of practices centered on an incremental development model.

We will review the principles of agile, with particular emphasis on the skillset expected of agile developers.

Objectives

1. Assess the impact of incremental models on a development project
2. Discuss the philosophy and components of agile models

Relevance

Agile development is one of the dominant approaches to software development for moderately sized projects developed by small (4–12 people) teams.

Agile presumes a skilled development team, familiar with a variety of standard tools and practices, which we will also need to assume that students in this course are familiar with:

• Incremental development
• Test-driven development
• Software configuration management
• Automated builds

4 Modern Software Construction

4.1 Unit Testing

Overview

In this section we will review the basic principles of unit testing, and then we will look at the problem of automating the testing oracle, the procedure of determining when our code has passed or failed each test.

This will lead us to the world of modern Unit test frameworks, which seek to make running tests so effortless that there is no longer any excuse to defer testing.

4.2 Build Management 09/15/2020 - 09/21/2020

Overview

A build manager has the task of performing any automated steps required to rebuild a software project after programmers have made changes. We will look at the primary models for build management, file dependencies and task dependencies, and the most commonly used managers for each model. We’ll also look at how to replace an IDE’s built-in builder with a more flexible manager.

Modern projects now rely on build managers for much more than just the basic operations of compiling and linking. Build managers are also called upon to run tests, to prepare software packages for deployment, to deploy them, and to prepare project reports and post those reports to project web sites. These demands go far beyond the capabilities of the simple manager included in your IDE. Used properly, a build manger can save a team a lot of tedious work.

4.3 Software Configuration Mgmt 09/23/2020 - 09/30/2020

Overview

Software Configuration Management (SCM) addresses a wide variety of issues in the development of software. These include version control, studied earlier, but also the problems of coping with portability to multiple target platforms and the incorporation of externally developed code libraries into a project.

Version control is concerned with managing the history of changes made to the software by the development team. A good version control system offers a team control over the history, exploration, and collaboration on a project. We’ll look at the issues and approaches to local, centralized, and distributed version control, and explore how to work with a distributed version control system from an IDE.

6 Presentations 11/09/2020 - 12/09/2020

Individual student presentations will take place over the final 5 weeks of the semester.

The order of student presentations will be based upon topics chosen – I will arrange them to provide as coherent an ordering as possible.
