Subject: Manipulate output from test/unit methods?


When you use any of the test/unit methods, like "assert_equal", you
always get a nice output message like

1 tests, 2 assertions, 0 failures, 0 errors

or

<"CLARICE"> expected but was
<"JOHN">.
1 tests, 1 assertions, 1 failures, 0 errors

How can I manipulate that output message, for instance assign the whole
string from "<"CLARICE"> to "0 errors" to a variable?

It's not in $_ or $! or $stdout or $stdout, and I can't seem to assign
it to a variable.  None of these work; the puts's are always "nil" or
something obscure from IO#:

a = assert_equal(x,y)
puts a

assert_equal(x,y)
puts $_

assert_equal(x,y)
puts $!

puts $stdout
puts $stdout
