未定义:revel.TestSuites

I'm having some problems getting Revel up and running after I did an update on the package. Each time I try to run a revel app I get the following error message:

Go Compilation Error
The Go code go/src/github.com/revel/samples/booking/app/tmp/main.go does not compile: undefined: revel.TestSuites

At first I thought this was due to some legacy code in my current project, but then I tried to get the official sample projects to work, but the same error comes up in these as well. Don't know how to push this further. I don't even use the testrunner, so it shouldn't even get generated in the main.go file.

Update

Looks like I had a old revel binary, had to remove this and get the revel cmd package, after I did this the TestSuites problem got solved.

I don't use Revel, but Godoc tells us that TestSuites is now in github.com/revel/revel/testing package. The Revel developers might've moved the testing related stuff into a separate package.
