Description

When running the tests on master branch as @mrparkers specified in the README

KEYCLOAK_CLIENT_ID=terraform \
KEYCLOAK_CLIENT_SECRET=884e0f95-0f42-4a63-9b1f-94274655669e \
KEYCLOAK_CLIENT_TIMEOUT=5 \
KEYCLOAK_REALM=master \
KEYCLOAK_URL="http://localhost:8080" \
make testacc

I'm getting the following erros:

resource_keycloak_custom_user_federation_test.go:87: Step 1/2 error: Error running apply: exit status 1
        
        Error: custom user federation provider with id custom is not installed on the server

Am i missing some configuration, or the tests are flaky?
