# Review Environments

sfops operate with the concept of review environments. Every change made to your salesforce repository is typically validated in a 'dedicated' review environment. These review environment is used for the following purposes

* validating whether a change is deployable
* validating whether any associated/impacted apex test classes are working as expected
* validating any end to end testing scenarios
* gather feedback from stakeholders for a change before the change is applied back to the trunk for releasing to production

As you could see from the above image, each work item (or change or pull request) is checked in a review environment. The associated pull request in Github will be provided with the details of the validation job
