I am creating SQL Server Unit Tests. We are testing various stored procedures.

Does anyone where or how to reinitialize the tables values in Sql Unit Testing? Resources are pretty new for unit testing in SQL SSDT VS 2017, so I think lot of people are trying to figure out and understand.

    The typical place for tear down scripts is in the Post-test, where you could include TRUNCATE or DELETE for the table(s) affected by the test. The general principals are that unit tests should not be dependent on one another and the outcome of a given unit test, pass or fail, should not affect the outcome of other tests so that they can be run independently of one another.

  • Agree with @DanGuzman, Still in case of relational data with Cascade Delete in Procedure we need to check the effect in relational table with cascade effect. This will require Tests created to each table separately and need to run each test in related sequence.

I have created the usp_Generate_Merge_For_Table procedure a few years ago exactly for this purpose.
It can generate a MERGE command with a Values Constructor in order to "re-initialize" the contents of a specific table.



You can find it here:



https://gist.github.com/EitanBlumin/7faba0b39c4f90d4cfa879a45f3e01eb#file-generate_merge_for_table-sql



Direct link to the raw script:



https://gist.githubusercontent.com/EitanBlumin/7faba0b39c4f90d4cfa879a45f3e01eb/raw/608177e77da0a42d686098ab10703bbba8c54d64/Generate_Merge_For_Table.sql



Simply create the procedure in your database, run it while sending it your table name as a parameter, like so:



EXEC usp_Generate_Merge_For_Table 'cities', 'dbo'


And then you can copy and paste its output in your Unit Testing project.
