Suddenly test::unit is failing for me. The following 2-line script  
comes up with

“testu.rb:2: undefined method `assert’ for main:Object (NoMethodError)”

testu.rb contains:

1: require ‘test/unit’  
2: assert(1==1)

What have I broken or forgot?  
ruby 1.8.2 (2004-12-25) [i386-mswin32]

It fails the same way under irb.

> Hi Warren,

normally the assert methods are accessible in subclasses of  
Test::Unit::TestCase. You could change your code to

require ‘test/unit’  
class AssertionTest \< Test::Unit::TestCase  
def test\_assert  
assert(1==1)  
end  
end

If you want to use assertions outside of testcases, look at module  
Test::Unit::Assertions.
