How to handle a codebase that depends on changing data?

I have two repos: - repo 1 creates data and store it in a database - repo 2 uses the data to do things

The problem I have is that changes in repo 1 obviously impact repo 2: some tests of repo2 are broken when data in the database is updated. I use circleCI to run tests in repo 2. The obvious solution would be to run the tests of repo2 to validate changes in repo1 but I don't see easy ways to do it.

Is there a standard workflow for that kind of problem ?
