Karan explained version control with the help of an easy example. Imagine you’re writing a script for automating test cases using tools like Selenium or Python. Without version control, when you need to make changes, you’d likely save new copies of your script with names like “**script-2.py**” or “**script-new.py.**” This leads to a messy and confusing collection of different versions.
{% twitter 1694067843929907380  %}
Karan highlighted that Version control, in simple terms, is like a way to save changes over time without erasing the older versions. It’s like creating snapshots of your work, allowing you to return to previous versions and move forward. Git is one of the most popular version control systems used for this purpose. It helps keep your work organized and accessible as it evolves.

![](https://cdn-images-1.medium.com/max/3200/0*7yw-asI21eWwLCKk.png)

* **Keeping Test Cases Alongside the Code:** He emphasized that keeping test cases alongside the code they are testing helps developers understand the expected behavior of the code and ensures that test cases are easily accessible and in sync with the code.

* **Reviewing Tests Using Code Review Processes:** Karan pointed out that when test cases are in version control alongside the code, they can be reviewed using the same code review processes organizations have in place for feature development. This alignment ensures that test cases receive the same scrutiny and attention as the code.

* **Log of How Test Cases Change Over Time:** Karan explained that version control serves as a log that tracks changes to test cases over time. This log allows teams to monitor the evolution of test cases, including updates, additions, and deletions. It’s particularly useful for tracking test coverage and quality metrics over time.

* **Shift Left Testing:** Karan mentioned that version control enables “shifting left” in the development process. This means that testing can occur earlier and more frequently in the development lifecycle, helping teams identify and address issues sooner, thereby staying closely aligned with the code changes and functionality.

## Key Terminologies in Git/GitHub

Before the demo, Karan discussed several concepts and terminologies related to Git and GitHub. These concepts serve as the foundation for understanding how Git and GitHub work together in development.

![](https://cdn-images-1.medium.com/max/3200/0*LQ7OKWEfBfOoerx0.png)

* **Repository (Repo):** Karan described a repository as a collection of files, including the history of changes and associated metadata. It’s akin to a folder but also stores the historical record of changes and additional information like messages and descriptions.

* **Commit:**He defined a commit as a snapshot of the entire repository at a specific point in time. Creating a commit means creating a snapshot of the files and their states.

* **Branch:** Karan explained that a branch can be considered a lightweight, movable pointer to a commit. It helps organize changes and workstreams. For instance, it separates different tasks or workstreams to avoid interference while developing code.

* **Pull Request (PR):** Karan outlined two ways to view a pull request. First, as a place to compare and discuss differences introduced in a branch. Second, as a request to merge changes from one branch into another, allowing code integration.

* **Clone:** He mentioned that a clone is a local version of a repository on a developer’s machine. It contains all commits and branches and allows developers to work on their code locally, making collaborating and managing versions easier.

* **Remote:** Karan described a remote as a common repository on platforms like GitHub for exchanging code changes. Multiple developers can synchronize their local repositories with a remote repository, facilitating collaboration and code sharing.

## Knowing the GitHub Flow

Karan explained the GitHub flow, a common development workflow used on GitHub. He highlighted that the GitHub flow is a structured way to develop and collaborate on code. It allows developers to work on features or fixes independently and then merge them into the main branch after review and approval. This workflow helps maintain code quality and ensures that new features are seamlessly integrated into the project.

![](https://cdn-images-1.medium.com/max/3200/0*udCJsOOIIFw0wmf4.png)

* **Main Development Branch:** In GitHub, a main development branch is often called the “master” branch or the “default” branch. This branch represents the main, continuous line of development.

* **Creating a New Branch:** When you want to work on a new feature or start a new task, you create a new branch based on the main branch. This new branch is your workspace for making changes without affecting the main branch.

* **Committing Changes:** After creating a new branch, you start making changes and commit them. Each commit represents a snapshot of the code at a specific point in time, capturing the modifications you’ve made.

* **Pull Request (PR):** To incorporate your changes into the main branch, you submit a pull request. This is a request to merge the changes you made in your feature branch into the main branch. PRs are where discussions, additional commits, and approval workflows can take place.

* **Approval and Merge:** Once a pull request has been reviewed and approved, the changes can be merged into the main branch. This means that the modifications you made in your feature branch become a part of the main branch, and the new code is integrated into the project.

## A Live Demo on the GitHub Skills Platform

In the demo, Karan showed how to use GitHub’s interface and the GitHub Skills platform to illustrate various concepts related to Git and GitHub. Here’s a detailed breakdown of what he demonstrated:

![](https://cdn-images-1.medium.com/max/3076/0*54GZut3BPnm3v6Lk.png)

* **Shell Scripts:** Users can write their shell scripts to define actions.

* **Custom Actions:** Users can also create custom actions using CoDe16 or Docker.

![](https://cdn-images-1.medium.com/max/3090/0*lQHYn5rCFYM0_JVh.png)

Karan then demonstrated how GitHub Actions fit a typical scenario where a build process is triggered by a commit or push event commonly used in CI/CD pipelines. He highlighted the key elements involved:

* **Event:** The event (e.g., push, commit, pull request) triggers the workflow file.

* **Workflow File:** A YAML file located in the .github/workflows directory of the repository that defines all automated procedures.

* **Jobs:** These are sets of steps executed on the same runner. Each job runs in its virtual machine and can run in parallel.

* **Runner:** The server with the GitHub Actions Runner app installed where actions are executed. Runners can be hosted by GitHub on their cloud infrastructure or self-hosted by users.

* **Steps:** The tasks defined in the workflow file can be actions from the marketplace, shell commands, or custom actions.

Karan also mentioned that GitHub provides live logs during workflow execution. These logs are displayed in real time and include deep links for easy navigation. Users can visualize the progress of workflows, especially when multiple jobs depend on each other. This helps users monitor and track how actions run together comprehensively.
