You can now deploy components to production by skipping the execution of all Apex tests for components that have been validated within the last four days. With Quick Deploy, you no longer have to wait for all tests to run for your deployment to complete in production, and your deployment will likely finish in less than 30 minutes
These requirements should be fulfilled for quick deployment
- The components have been validated successfully for the target environment within the last four days (96 hours).
- As part of the validation, all Apex tests in the target organization have passed.
- The overall code coverage in the organization is at least 75%, and Apex triggers have some coverage.
To validate components with the Force.com Migration Tool, set the checkOnly option to true in the deploy target and then you can use the ui to click on the quick deploy.
