Data (input) is passed to a function (or some block of code) which acts on the data and returns other data (output). Programs are largely “data in, data out”. Put aside databases for a moment, and let’s think about programs and data flow:

(We’ll explore this later.) Consequently, function logic and database access are tightly coupled, and tight coupling is usually poor software design. When there’s a bug in this function, it could be related to database access, or function logic given the data, or both due to concurrency, race conditions, database locking, database transactions, etc.

By “complete” I mean the code calling the database, the query, the database itself, and the data from (or to) the database.

The primary issue is: what is being tested? Presumably the function logic, but implicitly and indirectly the complete database access is being tested, too. This mélange is very common and tends to works ok when kept this simple, but there are issues and a better way. The problem arises when the code under test makes a database call: Code-Database SeparationĪ second reason testing the database seems difficult is less about the database and more about the code that uses the database. So set up for multiple db versions and variations. It’s even possible (and sometimes necessary) to test against multiple versions of the database. It can be a lot of upfront work, but if set up well it’s usually not much to maintain going forward, and the benefits more than surpass the initial effort.

If using a hosted CI solution, see if they offer database instances.

Spin up db instances in the cloud (e.g.

Roll your own sandbox with scripting (e.g.

Preexisting sandbox solution (like MySQL Sandbox).

The developer probably has an instance running on their laptop, but what about the CI system, staging, and production? Staging and prod presumably already have database instances, so the real challenge is programmatically setting up and tearing down a database in the test suites. One reason testing the database seems difficult is because it’s an external system. The question about testing the database implies that the database is a special beast that, if not treated properly, will devour the developer in their sleep. In other words: colleagues don’t ask, “How do I test such-and-such package?”, because that’s common and well understood. There’s a good, clean solution, but let’s first step back from what seems to be the problem to unpack why “testing the database” is not special (but nonetheless important). usr/share/perl/5.20.1 doesn't contain MySQL/ (using symbolic link can remove the error above, but I still have the wrong password.“How do I test the database?” is a question I’ve been asked by colleagues many times.
