Problem running tests

[Holger Schmeisky]

Hi,

I am trying to extend ruby-prof and want to run the tests for it. Installing the ruby-prof gem works flawlessly, but executing rake test yields:


MiniTest::Unit::TestCase is now Minitest::Test. From /usr/lib/ruby/1.9.1/test/unit/testcase.rb:8:in `<module:Unit>'
/usr/lib/ruby/1.9.1/test/unit.rb:328:in `autorun': uninitialized class variable @@installed_at_exit in Test::Unit::Runner (NameError)

I think this might be an issue with using Minitest and Test::Unit at the same time, because somebody else reports the same problem:

https://github.com/seattlerb/minitest/issues/283

But does anyone here have the same problem, or am I just doing something basic wrong?

Thanks for help,
Holger

Can you try with a pre-5.0 minitest (e.g.
minitest 4.7.5 or the one shipped with Ruby)?

Hi,

it works again if I change the gemspec to use minitest 4.0

 spec.add_development_dependency('minitest', "~> 4.0")

This was suggested in the github issue I linked to above.
