How to Use 'Go Hand in Hand' in Code Reviews

In a code review or pull request, you might read: "Testing and refactoring go hand in hand."

This idiom means two practices are closely connected and often happen together. However, it does not mean they always happen together, and it does not prove that one causes the other. They are connected activities.

Grammar: "Go" vs. "Goes With"

Pay attention to your subject when using this phrase in team discussions:

• Two concepts use go: "Testing and refactoring go hand in hand." Because the subject is plural (two actions), use go.
• One singular concept uses goes + with: "Testing goes hand in hand with refactoring." Because the subject is singular ("Testing"), use the singular verb goes followed by the preposition with.

Plainer Alternatives for Clearer Communication

Idioms can sometimes create confusion on international teams. If you want direct, plain workplace English for your pull request comments, use these alternatives:

• "Testing and refactoring work well together."
• "Testing and refactoring are often done together."
• "These two practices are closely linked."
