Git divide one project into two

Scenario:
I have an instrument test project, on master branch containing four tests.
Try to add two test: Create a new branch dev, add two tests.
Then later, we decide these two tests should be seperated into a new project

Solution:

1. Push currrent dev branch to remote
2. cd and mkdir, create a new folder(Not directly clone since there is already one existing project directory)
3. In the new folder, execute:

git clone --single-branch --branch=dev repoUrl

Now I have a new project containing only this specific branch dev

4. Rename dev to master:

git branch -m dev master

5. Create a new remote repository, and push master to the new repository

// Since this project is cloned from remote to local, there is already an existing remote repo
git remote set-url origin newRepoUrl
git push origin master

6. Rename project

• In android studio, open this new project
• In android studio top left, choose Project
• In app/src/androidTest/java/${projectName}, right click, choose Refactor - Rename
• In the new warning dialog, choose Rename Project
• File - Invalidate Caches / Restart
• In app - build.gradle, update applicationId
