I am having a problem with using the test-unit gem

I get a NoMethodError when I simply do

require ‘test/unit/assertions’  
#I’ve also used just require ‘test/unit’

def test  
assert\_equal(true, true)  
end

test

Sorry for such a simple question

I’m now reading that I have to be using ActiveRecord to use test-unit?  
Is that correct?

I don’t think it is correct…but you probably want to be using RSpec  
anyway. It’s a much friendlier test framework.

You should be creating a subclass of Test::Unit::TestCase in your file  
and defining tests within that.

# in a file named my\_test.rb (just convention, call it fred.rb if you

like)

require ‘test/unit’

class MyTest \< Test::Unit::TestCase

def test\_starting\_simple  
assert\_equal(true, true)  
end

end  
**END**

Then run that file with “ruby ./my\_test.rb” to get:

$ ruby ./my\_test.rb  
Loaded suite ./my\_test  
Started  
.  
Finished in 0.000476 seconds.

1 tests, 1 assertions, 0 failures, 0 errors

That should get you going.

The Test::Unit::Assertions module defines instance methods, so you have  
to mix that module in to some object or class.

You can do this:

```
include Test::Unit::Assertions
def test
  assert_equal(true, true)
end
```
