Hi,

stack test does not execute the detailed-0.9 test suite, see minimal example (including working instructions for cabal-install):
https://github.com/michaxm/test-detailed-example

stack test
Test suite test-detailed-example-test executable not found for test-detailed-example
Test suite failure for package test-detailed-example-0.1.0.0
test-detailed-example-test: executable not found

Tested with 1.6 and current master, same result:
