Hi! I'm working on a native driver for MySQL. The documentation for SQLDelight says:

To test the driver you can depend on the driver-test and extend DriverTest and TransactionTest to ensure it works as SQLDelight would expect

However, that line is 3 years old, the DriverTest-class defines its package as com.squareup.sqldelight.driver.test not app.cash.... , and I can find neither app.cash.sqldelight:driver-test nor com.squareup.sqldelight:driver-test.

Am I doing something wrong or is that piece of documentation incorrect?

That comment in the docs is definitely out of date/lacking clarity.

The driver-test module isn't published, and I think it was more meant for internal testing of "first-party" drivers. It predates dialects other than SQLite so it isn't really set up to test those kinds of drivers.

I think the module can still serve as a helpful reference to see the kinds of behaviours that you should test on your driver, but you'll have to implement them for your driver separately.

I'll see about updating the docs to clarify how/what to test drivers

[Derek Ellis]

and also if your driver is open source, we'd love to feature it in the docs!

Thanks for the clarification Derek!

and I think it was more meant for internal testing of "first-party" drivers.

I started copy-pasting the abstract test classes from the SQLDelight repo and I noticed this. So far, I've got the DriverTest s and most of the `QueryTest`s working with only minor changes to get around the SQLite-specific stuff.

and also if your driver is open source, we'd love to feature it in the docs!

It will be, as soon as I've got the whole interface implemented and all tests passing
