Testing a new application involves testing in different environments.

• Testing and deploying application changes

  Test a new application in the Build environment before migrating the application to a test or production environment. Testing in the Build environment enables you to verify that basic functionality and interfaces work correctly, and that performance is acceptable.

• Testing in the test or production environments

  After you import your application to a test or production environment, test the application in the new environment to verify that it works correctly in that environment.

• Testing in the UAT environment

  After you complete testing in a Test environment, it is common to perform User Acceptance Testing (UAT) in a designated UAT environment, which could be a preproduction environment. UAT ensures that users will be able to successfully complete their work and meet business objectives.
