I am unable to run serverless.test.yml

I have implemented serverless.test.yml but when running sls test I get

Serverless Error ----------------------------------------

Run “serverless” to configure your service for testing.

For me it was easier and ultimately more reliable to test on actual AWS resources in the cloud. I could use the node SDK to create tables in the test set up and then tear down 9Apps Showbox Tutuapp after. You’re unlikely to incur costs for it also.
