Failed to load ApplicationContext while running integration test in grails - grails

Question

I'm trying to create my first integration test in Grails. For this I executed: grails create-integration-test MyClass which created an empty IT. Thats how it looks like:
import grails.test.mixin.integration.Integration
import grails.transaction.Rollback
import spock.lang.Specification
#Integration
#Rollback
class MyClassSpec extends Specification {
def setup() {
}
def cleanup() {
}
void "test something"() {
expect: "fix me"
true == false
}
}
When I run the test with grails test-app -integration it doesn't complain about the true==false but gives me this error:

I'd guess that Grails isn't able to connect to the database somehow. Do I have to add something to my application.yml, where I have stored my DB-connection information? Or am I missing something else?
By the way: My Grails application is running with grails run-app while executing the IT and I'm using Grails 3.0.9.

Update 2:
It seems that I can run the IT manually (using IntelliJ Idea) but not with grails test-app.

Answer 1

Your application.yml file doesn't contain url in dataSource configuration for test environment, causing the hibernate to fail while configuring the database connection settings.
You need to add the configuration details for other environments also like test or production, if you are planning to run your application there.
