[git] Is it possible to pull just one file in Git?

I am working on a Git branch that has some broken tests, and I would like to pull (merge changes, not just overwrite) these tests from another branch where they are already fixed.

I know I can do

git pull origin that_other_branch

but this will attempt to merge lots of other files, for that I am not yet ready.

Is it possible to pull and merge only the specified file (and not everything) from that another branch?

This is not a duplicate of Git pull request for just one file as all answers to that question are how to revert the locally changed file to the repository version, without changing any branches.

Here is a slightly easier method I just came up with when researching this:

git fetch {remote}
git checkout FETCH_HEAD -- {file}

Yes, here is the process:

# Navigate to a directory and initiate a local repository
git init        

# Add remote repository to be tracked for changes:   
git remote add origin https://github.com/username/repository_name.git

# Track all changes made on above remote repository
# This will show files on remote repository not available on local repository
git fetch

# Add file present in staging area for checkout
git check origin/master -m /path/to/file
# NOTE: /path/to/file is a relative path from repository_name
git add /path/to/file

# Verify track of file(s) being committed to local repository
git status

# Commit to local repository
git commit -m "commit message"

# You may perform a final check of the staging area again with git status

git checkout master -- myplugin.js

master = branch name

myplugin.js = file name

@Mawardy's answer worked for me, but my changes were on the remote so I had to specify the origin

git checkout origin/master -- {filename}
