Make sure to initialize the AppDataSource like AppDataSource.initialize() before running tests within the it chunk
Since we have validators/middleware, you can't just call the method to test! We have to call the validator, and then pass in whatever method as the nextFunction:
createUserValidator(s,s2,() => createUser(s,s2));
AppDataSource.initialize()
before running tests within the it chunkcreateUserValidator(s,s2,() => createUser(s,s2));
