We started a 2 week sprint assuming that the testing environment is ready. However, we found out during the sprint that it is not ready. We kept working on tasks like like development, code review, and creating test cases. In parallel, we tried to get the testing environment up and running.
Now the sprint timebox is over, and the testing environment issue is not resolved. So, none of the users stories is tested, hence none of them is "Done".
What is the best practice in the sprint review of such sprint?
