By default Rails filters that backtrace and will only print lines relevant to your -application. This eliminates the framwork noise and helps to focus on your +application. This eliminates the framework noise and helps to focus on your code. However there are situations when you want to see the full backtrace. simply set the `BACKTRACE` environment variable to enable this behavior: @@ -401,8 +401,8 @@ Rails adds some custom assertions of its own to the `test/unit` framework: | `assert_no_difference(expressions, message = nil, &block)` | Asserts that the numeric result of evaluating an expression is not changed before and after invoking the passed in block.| | `assert_recognizes(expected_options, path, extras={}, message=nil)` | Asserts that the routing of the given path was handled correctly and that the parsed options (given in the expected_options hash) match path.
