Hey everyone,
I’m looking for advice on unit testing stored procedures. We’ve had great results with our C#/C++ unit tests, but our database code is still a challenge.
Our stored procs have tons of business logic, and they’re only really tested when we deploy to users. Some are super long due to performance concerns with temp tables. This makes refactoring tough.
We tried setting up tests for key procs, focusing on performance. But creating test data is a nightmare. We ended up copying entire test databases! Plus, the tests are super fragile. Any tiny change to a proc or table means we have to update a bunch of tests.
Has anyone cracked the code on this? How do you unit test your stored procedures effectively?
Also, I’m curious if LINQ might make this easier. Could we use LINQ to Objects with test data collections instead of actual database tables? I’m new to LINQ, so I’m not sure if that’s even possible.
Any tips or experiences would be really helpful. Thanks!
yo, have u thought about mocking the database? it’s a game-changer for unit testing SPs. you could create fake data that mimics your real db structure. might help with those monster procs too - break em down into smaller bits, test each part. what about using dapper? heard it plays nice with LINQ and makes testing easier. jus a thought!
Have you considered using tSQLt for unit testing your stored procedures? It’s specifically designed for SQL Server and offers a structured approach to testing database code. tSQLt allows you to create isolated test environments, mock tables and views, and even fake stored procedure execution results. This could help address your concerns about test data management and test fragility.
For those long, complex procedures, you might want to look into breaking them down into smaller, more manageable units. This not only makes testing easier but also improves maintainability. Consider extracting common logic into separate procedures or functions that can be tested independently.
Regarding LINQ, while it’s great for application-level testing, it might not be the best fit for directly testing stored procedures. Instead, you could explore tools like Dapper or Entity Framework for data access in your application, which can simplify integration testing of your database code.
hey there! have you considered using database snapshots for isolation? that could help with the test data nightmare. what about breaking down those mega-procs into smaller bits? might make testing easier. curious, have you tried any specific sql testing frameworks? i’ve heard good things about tsqlt, but never used it myself. wat do you think?
