Logging in a GrailsUnitTestCase?

Question

How do I setup logging in a grails unit-test?

When I try log.info or log.debug, the .txt output files are empty, even after I tried adding a console appender. What's going on here?

Answer 1

If you extend GrailsUnitTestCase, you ought to be able to use mockLogging(), but the appenders you set up in Grails config won't be applied in a unit test, which works in isolation from the real framework. They'd only be available in integration tests.

Answer 2

This might help, it's taken from the 1.2 release notes

By default, grails does not show the output from your tests. You can make it do so by passing -echoOut and/or -echoErr to test-app:

grails test-app -echoOut -echoErr
