SDET Interview Preparation - GIT and GitHub for Version Control

1. Introduction to Version Control Systems:

Version control systems allow multiple people to work on a project without overwriting each other's changes. They track modifications to a project, so a specific version can be recalled later.

Understand what version control is and why it's essential in software development.

2. Basics of Git: 

Git is a distributed version control system. It allows you to track changes, create branches, and more. It's essential for managing and collaborating on projects.

Learn about Git, its architecture, and its importance in version control.

3. Git Installation and Setup:

This involves downloading and installing Git on your system, setting up your username and email, and initializing your first repository.

Understand how to install Git and set it up on your local system.

4. Git Commands:

Basic Git commands include 'git init' to initialize a repository, 'git clone' to copy a repository, 'git add' to stage changes, 'git commit' to save changes, 'git push' to send changes to a remote repository, 'git pull' to fetch and merge changes from a remote repository, and 'git status' to view the state of your repository.

Learn the basic Git commands like git init, git clone, git add, git commit, git push, git pull, and git status.

5. Branching and Merging:

Branches allow you to work on different features simultaneously. Learn how to create a branch with 'git branch', switch to it with 'git checkout', and merge it with 'git merge'.

Understand the concept of branches in Git, how to create and switch between branches, and how to merge changes.

6. Resolving Merge Conflicts:

Merge conflicts occur when changes clash.

Learn how to identify and resolve these merge conflicts.

7. Git Stash:

'git stash' temporarily saves changes that you don't want to commit immediately. You can apply the stashed changes later.

Understand how and when to use the git stash command.

8. Introduction to GitHub:

GitHub is a web-based hosting service for Git repositories. It provides a graphical interface for managing repositories and includes features like bug tracking, task management, and wikis.

Learn about GitHub, how it works with Git, and why it's used.

9. Working with Remote Repositories:

Learn how to link a local repository to a remote one, push changes to the remote repository, and pull changes from it.

10. Pull Requests and Code Reviews:

Pull requests let you tell others about changes you've pushed to a GitHub repository. Code reviews on GitHub are a way for other developers to give feedback on your code.

Learn how to create a pull request and how to review code on GitHub.

11. GitHub Issues and Labels:

Issues are a way to track bugs, enhancements, or other tasks for your project. Labels help you categorize and filter issues.

Understand how to use issues and labels to track and manage bugs and tasks.

12. Integrating Git with IDEs:

Many Integrated Development Environments (IDEs) have built-in support for Git. 

Learn how to use Git within various Integrated Development Environments (IDEs).

13. Best Practices:

Good practices include making frequent, small commits, writing clear commit messages, using branches for new features or bug fixes, and regularly pulling and pushing changes.

Learn the best practices for using Git and GitHub, including commit messages, when to branch and merge, and more.

14. Advanced Git Concepts:

Rebasing and cherry-picking allow you to modify commit history. The .gitignore file tells Git which files to ignore.

Cover advanced topics like rebasing, cherry-picking, and using the .gitignore file.

15. Git in CI/CD pipeline:

In a Continuous Integration/Continuous Deployment (CI/CD) pipeline, code changes are regularly built, tested, and deployed. Git plays a crucial role in this process.

Understand how Git fits into a Continuous Integration/Continuous Deployment (CI/CD) pipeline.
