Which of the following commands allows you to switch to a new Git branch called testing?
a. git branch testing
b. git commit ‐m “testing”
c. git checkout testing
d. git branch
The correct answer and explanation is:
The correct answer is a. git branch testing.
In Git, branches allow developers to work on isolated changes without affecting the main codebase. To switch to a new branch, you first need to create it and then move to it. The command that both creates a new branch and allows you to switch to it is git checkout -b <branch-name>. However, among the provided options, the command git branch testing will create a new branch called “testing,” but it will not switch to it. To switch to the newly created branch, you would need to use git checkout testing.
Here’s an explanation of each option:
- a. git branch testing: This command creates a new branch called “testing,” but it does not switch to it. You would still be on your current branch. To switch to the new “testing” branch, you need to use
git checkout testingafter this. - b. git commit ‐m “testing”: This command is used for committing changes to the current branch with a message. It does not create or switch branches. The
git commitcommand is part of the version control process to save changes made to files. - c. git checkout testing: This command is used to switch to an existing branch called “testing.” If the branch doesn’t exist yet, Git will show an error message.
- d. git branch: This command shows a list of all branches in your repository, highlighting the current branch. It does not create or switch branches.
In summary, git branch testing will only create the new branch, and you would need to run git checkout testing separately to switch to it. If you want to create and switch to a new branch in one command, the correct command would be git checkout -b testing.
