'Cannot resolve symbol should' - why?

[Eric Fowler]

I have an SBT project in in Intellij IDEA with a test directory in the usual place, and scalatest and scalautils designated as external libraries. 

IDEA is flagging 'should' and 'in' with red text, and saying it can't resolve them. 

How can I set up scalatest to run in this environment? Where is 'should' defined?

Mind, I am pretty new to scalatest and IDEA. 

Thanks

Eric

IntelliJ is not at its best when auto-detecting the necessary imports for things like `should` etc in Scala (I mean, as compared to its fantastic-outstanding self when doing the same for Java).

You are most likely missing this import:

import org.scalatest._

(see the code here, and here for a full example).

I have had some trouble getting the whole thing to work in Scala, so you may also want to check out my build.sbt and friends.

Hope this helps.

Hi Eric,

Another possibility is you didn't mix in Matchers or import Matchers._. The implicit conversion that adds should to any type is in org.scalatest.Matchers, which is not mixed into style traits by default.
