Chris Adkin shows off parallelism in Azure DevOps continuous integration pipelines:
A SQL Server data tools project is checked out of GitHub, built into a DacPac, four containerized SQL Server instances are spun up using clones of the ‘Seed’ docker volume. The DacPac is applied to a database running inside each container, which a tSQLt test is then executed against, finally, at the end very end the tSQLt results are aggregate and published.
This is an interesting approach to the problem of lengthy tests: run them on several separate machines concurrently.
