scala - How to execute tests that match a regular expression only?

Question

In sbt 0.10.1, I frequently use test-only to narrow down the number of my tests.

sbt> test-only com.example.MySpec

However, I want to narrow down such that I only run tests whose name/description matches a regular expression. Is there some syntax to achieve something like this?

sbt> test-only .*someRexExp.*

Answer 1

Full regular expressions are not supported by testOnly. Wildcards are supported, however.

sbt> testOnly com.example.*Spec

Only the asterisk * is interpreted specially here and not the periods. This will select all tests beginning with com.example. and ending with Spec.

Or just all test Specs:

sbt> testOnly *Spec

testOnly and other testing information is documented here: http://www.scala-sbt.org/release/docs/Detailed-Topics/Testing
