Can't run integration tests in purely DB-less mode

[arunramani]

I'm developing a plugin using the kong-plugin template. After cloning the template I switched the for loop in the integration spec from

for _, strategy in helpers.all_strategies() do

to

for _, strategy in ipairs({"off"}) do

This causes pongo to throw the following error:

However if I run the postgres strategy first, then the DB-less strategy works. Any suggestions on how I can get this working for just DB-less?

Check the original template. It requires a Postgres db. Even for db less, since the test helpers wrote to the db. Only when running db less tests it exports and starts db less.

EDIT: typo

[Tieske]

I assume this is fixed, hence closing. Please reopen if not.

It's time and resource-consuming for the build, why do I need to have postgres db if I'm using db-less. I believe refactor for test helpers is required here to accommodate the db-less as well.

Also what is the point of having like this --no-postgres --no-cassandra

I will be always getting similar error response for Cassandra as well

This test tool caters for a wider audience than just the DB-less. You get some, you loose some.
