CPSC 480-020 Software Engineering (SE) Fall 2026

Week 4 Class 7 Tue Sep 15 Posted: Sep 15

Announcements:

• Exercise 11: GitHub Username

  There are three steps to allow you to create repositories for the projects and some of the exercises:

  1. You provide your GitHub username
  2. I add you to the roster of the course in Classroom 50 (already completed for those who provided their GitHub username)
  3. GitHub sends you an invitation to become a member of the UACPSC organization, and you accept it.

  For 3, I indicated in your feedback for Exercise 11 if this was not accepted yet, then you need to accept the invitation

  Invitations are email to the email account for your GitHub Username. I assume in most cases this is your UA email.

  You can also view these on your GitHub Organization Page

  If you accept the invitation, I will give you full credit for this exercise.

• Windows File Explorer & WSL

  To open the Windows File Explorer on the current directory in WSL:

  The . means the current directory in WSL. You can also open a file explorer.exe Requirements.md. If you open a path it has to be in Linux format, e.g., C:\Users\JohnDoe\Documents would be /mnt/c/Users/JohnDoe/Documents.

• Assumptions

  I noticed that many of the assumptions mentioned are about the difficulty of implementation. This is not what the book discusses. Instead, they are assumptions about what the user story means. The only person who can answer those assumptions is the customer.

  From now on, label assumptions about the user story as assumptions and assumptions about implementation as implementation.

• Dependencies

  I see a lot of user story estimates where the assumptions include the completion of a previous user story. This is a dependency. Avoid dependencies at all costs. For example, Add … does not have to be completed before Delete …. Obviously there will be some dependencies, but they are to be at the user-story level, not the implementation level.

Class

• GitHub Codespaces
• GitHub Authentication
• Creating the Report
• Git Commands The table will expand as we use more commands

• Exercise 13: Commit to Project 1 Repository

  Following the procedure given in the assignment and demonstrated in class, contribute at least one commit to the Project 1 repository. This must be a valid and useful commit.

  • Use the git CLI to make the commit. You can do this wherever you have the repository cloned. You can even do this in a GitHub Codespace
  • Good commit messages follow certain patterns, and you need to follow them on all git commits:
    • Start with an action, e.g., Add
    • Capitalize the subject line (the only line we are using)
    • Use the imperative mood, e.g., Added, Adding, Adds, Add
    • Do not end the subject line with a period

  You can see your commit messages with the git log command.
