How to Use Test Files in Grails
I’m embarking, balls-out, on a new project using Grails. I’ll be leveraging a significant portion of our Java codebase and the fact that I can do that,is just plain stellar.
It quickly came time to test out some of the integration. The very first question was how to load resources for testing. E.g., I have a service that handles file uploads. How do I pass it a test file?
The documentation isn’t straightforward on this. In fact, I found the solution attached to a bug report for grails 1.1. It’s pretty simple, once you pull in the spring packages:
import org.springframework.core.io.ClassPathResource import org.springframework.core.io.Resource
And then in your testXXX() function:
Resource resource = new ClassPathResource("resources/crying-baby.jpg") def file = resource.getFile() assert file.exists()
And you are good to go. Note the assert at the end to verify things are working.
