I’m struggling to understand the combinations in which MiniTest and  
Test::Unit can be used. This is my understanding so far…

Test::Unit

Available as a standard library (‘test/unit’) in Ruby versions before  
1.9.1.  
Available as a standard library in Ruby version 1.9.1, but only as a  
thin  
wrapper around MiniTest. Some Test::Unit API no longer available.

MiniTest

Available as a gem (‘minitest’) in Ruby versions before 1.9.0  
Available as a standard library (‘mini/test’) in Ruby version 1.9.0  
Available as a standard library (‘minitest’) in Ruby version 1.9.1

Is that all correct?

Also when is the minitest\_tu\_shim gem intended to be used?

Thanks.

You can also gem install test-unit -v 1.2.3 on 1.9.1 to get back the  
full blow ‘old school’ Test::Unit
