Study Notes
Software Testing - Version Control Systems
- Version control systems are repositories for software.
- They maintain multiple versions of the software.
- This allows saving previous versions alongside new ones.
- Reversion to a previous version is easy if a mistake is made.
- Version control can be local or remote.
- Git is a popular version control system.
- Seneca College uses its own Git server accessible via VPN.
- The URL for the server is https://github.senecacollege.ca
Git Clients
- Git clients are programs for interacting with Git repositories (local or remote).
- Clients can create clones of repositories.
- They allow adding new files to a repository.
- They can retrieve information about the repository.
- TortoiseGit is a Git client integrated into the Windows file browser.
- There are other Git clients available.
TortoiseGit Menus
- TortoiseGit menus have options depending on whether you're dealing with a repository or not.
- Non-repository menus: Git Clone, Create repository here.
- Repository menus: Git Sync, Git Commit, TortoiseGit.
Working Copies
- Cloning a remote repository creates a local copy.
- Users make changes in the local repository.
- Changes are committed to the local copy.
- Files are staged for the next push.
- Changes are pushed to the remote repository for sharing.
Diagram of Working copies
- The diagram shows a circular process:
- Clone Repo
- Edit/debug
- Push
- Commit
- Stage
Working Copies - Network Repository
- A central network repository exists.
- Local working copies exist in separate locations (e.g., Alice's copy, Pete's copy).
- The network repository is the central storage for shared code.
File Status
- Git tracks only the files that are requested.
- Files must be added to Git for tracking.
- Projects have intermediate and various file types (objects, executables) that can potentially be rebuilt.
- Git informs if files have been modified after being tracked.
- Files can be staged and committed after they have been modified.
Diagram of File Status
- The diagram visualizes the process:
- Untracked
- Modified (after an edit)
- Unmodified (no change)
- Staged (ready for commit)
Tortoise: Check for Modifications
- TortoiseGit can show file status (Modified, Added, etc).
- It displays the path, extension, status, added lines, removed lines, and the last modified date of files.
- It shows unversioned or modified files.
- The file path, extension, status, lines added, lines removed, and the last modified date.
Ignoring Files
- Temporary files can be ignored with a ".gitignore" file.
- A list of patterns specified in the file tells Git which files to ignore.
- Specified patterns include: *.vsidx, *.lock, *.ipch, *.testlog, *.tlog, *.log,
- .VC.db, *.manifest, *.VC.db-shm, *.VC.db-wal, *.VC.db-opendb.
Communicating with the Remote Repository
- Clone - creates a local copy of the repository.
- Pull - updates the local copy from the remote.
- Push - sends local changes to the remote repository.
Other Actions
- Rename - changes the name of a tracked file in Git.
- Delete - removes a file from Git's tracking.
Viewing Changes
- TortoiseGit displays changes compared to the base version.
- The software shows the differences between two files (e.g., the working tree and a particular version).
Conflicts - Two Developers Change the Same Line
- Conflicts arise when multiple developers modify the same line of code simultaneously.
- TortoiseGit manages merge conflicts and displays them if needed.
- Displays the modified code lines.
