Q.

Warning messages are shown during deploy.

A.

Upon deploying, the Deployment Completed dialog appears like the image below with a message saying "Response had the following warning messages."

This might occur when any of the following conditions is met.

The destination organization is not a Production environment （Sandbox　 or Developer）
Partial test was selected as the deploy option.
Trigger tests or independent test classes exist in the destination organization.

Even if the above warnings appear, they are independent of the deployed class and should not cause any problems.
