For the AZ-400 exam, the most effective way to ensure a consistent state for integration testing against a SQL Server database is to automate a database restore from a backup before each test run. While manual resets are error-prone and skipping resets leads to ""flaky"" tests or false positives, using a dedicated pipeline task—such as Azure CLI, PowerShell, or the SQL Azure Database Deployment task—guarantees that every test begins with a known, clean dataset. This pattern enforces reliability and repeatability, ensuring that test failures are due to code issues rather than leftover data from previous runs.
