Software Collaboration INTRODUCTION

In this module of the Coursera Meta Front-End Developer Professional Certificate, you will learn about how modern software developers use version control systems to collaborate across the world. Software collaboration is essential for large software projects that have a high potential for mistakes and bugs. You’ll explore different methods of version control, such as Git and Subversion, and you’ll learn how to create an effective software development workflow. By the end of this module, you will be able to design and implement a successful version control strategy for your software projects.

This is an essential skill for any modern Software Developer, so enroll now in the Coursera Meta Front-End Developer Professional Certificate and begin your journey to becoming a Software Collaboration Pro!

Learning Objectives

  • Describe how modern software teams collaborate and work on the same codebase.
  • List different version control systems and methodologies.
  • Illustrate a standard software development workflow.

KNOWLEDGE CHECK: INTRODUCTION TO VERSION CONTROL

1. Which of the following are the benefits of using Version Control?

Select all that apply.

  • Identity (Correct)
  • Revert / Rollback (Correct)
  • Collaboration (Correct)

Correct! Version Control allows you to identify who made changes to a file, when they were made and what changes occurred.

Correct! Version Control allows you to set your files to a previous state at a specific point in time.

Correct! Version Control allows multiple developers to collaborate on a codebase with each other.

2. When multiple developers work on the same file, a merge conflict will never occur.

  • True
  • False (Correct)

Correct: A merge conflict can occur and a developer will need to resolve the conflict.

3. Revision History is a record of all changes within a project. It allows you to pinpoint who made the changes, when they were made and what was changed.

  • True (Correct)
  • False

Correct: When files are changed, the changes are tracked through the Revision History.

4. Which of the following are centralised Version Control Systems? Select all that apply.

  • Concurrent Versions System (Correct)
  • Mercurial
  • Subversion (Correct)
  • Git

Correct! CVS is a centralised version control system.

Correct! Subversion is a centralised version control system.

5. Which of the following complements Version Control during software development? Select all that apply.

  • Continuous Integration (Correct)
  • Continuous Delivery (Correct)
  • Continuous Deployment (Correct)

Correct! Continuous Integration is used to automatically integrate code changes.   

Correct! Continuous Delivery automatically packages the application and prepares it for deployment.

Correct! Continuous Deployment helps to deploy the application to customers frequently.

6. Your development team is tasked to develop an app. Your project manager leads you to work in an Agile way of working where tasks are planned and executed in a two-week cycle.  This is done to ensure which of the following benefits?    

  • Create a better team spirit
  • Speed of programming
  • Efficiency (Correct)

Correct: Well done! You, as a developer, will normally work on a project alongside many developers and team members with other skillsets. You and your team need to be efficient to make the project a success. To achieve this, you and your team normally work in an agile process.     

7. You are working with a team of developers on an app to help people work more efficiently. While you are developing this app the codebase you are working on goes through many revisions as each potential change gets peer-reviewed and given the ok. What is this system of checks that provides a detailed record called?    

  • Debugging
  • Version control (Correct)
  • Track changes

Correct: That is correct! Version control is the term given to the system used to keep a detailed record of all changes to the codebase.    

8. You are part of a development team and one of your colleagues ask you if a Centralized Version Control system (CVS) contains a server and a client. What would your answer be?

  • Yes (Correct)
  • No

Correct: That’s correct! A Centralized Version Control system (CVS) contains a server and a client.

MODULE QUIZ: SOFTWARE COLLABORATION

1. What is Revision History in Version Control?

  • A record of all changes in a project (Correct)
  • A record of all bugs in a project
  • A record of all users in a project

Correct! Revision History is a record of all changes within a project. It allows you to pinpoint who made the changes, when they were made and what was changed.

2. When using a Distributed Version Control System, a connection to a central server is always required to perform an action.

  • True
  • False (Correct)

Correct! In a DVCS, you can work in an offline state and only connect to a server to push and pull changes.

3. A Version Control system allows you to roll back your files back to a specific point in time.

  • True (Correct)
  • False

Correct: Revert/Rollback is a common feature in version control systems.

4. When using a Centralised Version Control system, for other developers to see your changes you must commit them to a central server.

  • True (Correct)
  • False

Correct: All actions must be done through the central server.

5. Version Control is inefficient when multiple developers work on one project.

  • True
  • False (Correct)

Correct! Version Control combined with testing and automation allows a development team to work efficiently.

6. __________________ automatically packages an application and prepares it for deployment.

  • Continuous Integration
  • Continuous Deployment
  • Continuous Delivery (Correct)

7. Which of the following are distributed Version Control Systems? Select all that apply.

  • Git (Correct)
  • Mercurial (Correct)
  • Concurrent Versions System

Correct! Git is a distributed version control system.

Correct! Mercurial is a distributed version control system.

8. What are the main benefits of having a staging environment?

  • It can allow teams to demo or showcase new features in a controlled environment. (Correct)
  • It provides a safe place to test and verify changes prior to being deployed to a live production environment. (Correct)
  • It allows developers to add new features directly to production.
  • A staging environment mimics the production environment which allows for more accurate testing to find any possible issues. (Correct)

Correct! Staging can be used to demo new features and changes without impacting the production site.

Correct! Staging is its own environment and any changes made to it do not affect the production environment in any way. It is completely isolated.

Correct! Having the same setup as the production environment gives peace of mind that the changes being introduced are not going to cause issues when released to production.

Software Collaboration CONCLUSION
