CSE 403: Software Engineering

This lecture summarizes essential tools and techniques for developing software in teams, as discussed in CSE 403. Key aspects include online project hosting options, version control systems, collaborative design and implementation practices, and testing frameworks. Emphasizing efficient team dynamics, the lecture also highlights the importance of adhering to software engineering standards and maintaining clear communication. Participants are encouraged to provide feedback and engage with various tools like Git, Mercurial, and UML for visual documentation.

  1. CSE 403: Software Engineering Tools for Developing Software in Teams

  2. Introduction David Notkin (notkin@cs) Kıvanç Muşlu (kivanc@cs) Anton Osobov (aosobov@cs) Instructor TA TA • This lecture aims to summarize the information available at Google Doc • Please comment it with your knowledge and experience – requires @cs accounts • PDF version is available on the web page

  3. CSE 403 Tool Needs • Produce documents and draw designs • Implement code as a team • Write unit tests, documentation, etc. • Produce internal and external web pages • What is the most efficient way to do these?

  4. Phase 0: Project Hosting • Online hosting sites are highly encouraged • Comes with version control system, bug tracking and wiki • We suggest • Google Code: Quick Fix Scout and Google Web Toolkit • Github, Bitbucket or Sourceforge • Private hosting at CSE servers is also possible • However, you need to convince us about why this is crucial for your project

  5. Version Control Systems: Why? • Allows developers to work concurrently • Personal changes do not effect each other unless published • Preserves a history of the changes • If something goes bad developers can rollback to a ‘stable’ state • Using a VCS is a natural requirement! • If not, believe us that you WILL regret it!

  6. Version Control Systems: Types • Distributed (suggested): Mercurial (HG), Git • A “central” repository • Distributed private (personal) repositories • Personal workspaces • Make changes => commit locally => push to share • Central: CVS, SVN (Subversion) • A central repository • Personal workspaces • Make changes => commit to share

  7. Phase 1: Design • Quite complex ranging from: • Low level decisions (e.g., which data structure to use) • High level abstractions (e.g., architecture diagrams) • In any stage, Unified Modeling Language (UML) is very popular to generate diagrams • e.g., Omondo plug-in for Eclipse • There are lots more on the web page!

  8. Omondo UML Example

  9. Phase 2: Implementation • Choose a programming language • High level languages (e.g., Java, C#) are suggested • Choose an IDE: Eclipse, Visual Studio, etc. • Free to choose the language, platform, IDE. Just make sure that your final implementation • Conforms to software engineering standards • Consistent with your requirements, design & specifications

  10. Phase 3: Testing • Finds bugs in your implementation • Checks its correctness (up to a degree) • Available Frameworks • JUnit (Java, comes with Eclipse) • .Net includes testing for C# (comes with VS) • Quality vs. quantity of the tests • Coverage tools to approximate quality: Java

  11. Extra Tools • Crystal (contact Yuriy Brun) • Works with Git & Mercurial • Notifies developers as soon as conflicts occur • Can save a lot of time! • Quick Fix Scout (contact Kıvanç Muşlu) • Works with Eclipse Classic 3.7.1 • Helps you to resolve compilation errors easier • They are NOT required but can help you • We would appreciate the feedback

  12. Initial Advice • Quarter is short, don’t stuck with details • Try to keep up with the internal deadlines • If you are unsure about something, ask us • We don’t also know every available thing out there, but will do our best to help! • If you ever have a problem about the course requirements or your team, let us know

  13. Final Words • Learn available tools and technologies • Learn how to build software as a team • Have fun through the quarter!

  14. Reminders • Webpage: Updates & announcements • GoPost Forums: Discussions & lecture summaries • 3+ people in each group (one must be a program manager, a “PM”) • Project proposals descriptions and slides (presented by you at lecture on Friday) • Proposals based on the KNOW (Jackson School) ideas or on your own ideas • Thursday, we meet again to form the teams • Project and team preferences submitted by Friday night • Projects and teams announced by Saturday night
