I generated a new rails app then installed rspec and rspec_on_rails from trunk. I then created a sample story: require File.dirname(__FILE__) + "/helper" Story "View Home Page", %{ As a user I want to view my home page So that I can get a birds eye view of the system }, :type => RailsStory do Scenario "Publisher with no videos" do When

There is an option "--reverse" to run examples in the reverse order which is good for detecting inter-dependencies between examples. Is it feasible for rspec to automatically switch between "forward" and "reverse" order each time a spec is run? My goal is to detect inter-dependencies sooner than later... Thanks Alvin.

After trying RailsStory for a few days, I have learned: 1. Rails testing support does not serve up static pages 2. RailsStory masks errors generated by the app under test 3. The masked errors are available in log/test 4. I should read log/test more often See http://pastie.caboo.se/107876 for an example for points 2 and 3 The welcome controller fails when the HTTP_USER_AGENT is missing.

Hi there. Just a little status update how that integerization is coming along. I am trying to limit myself to 32 bit arithmetics. That means not using any __int64 or long long datatypes at any point. I have now replaced all steps up to including the estimation of the LPC filter coefficients with integer code. That is about a quarter of the total work completed, I would say. One problem that i

With rspec 1.0.8 I have a spec in the directory: spec/units/controllers/application_controller_spec.rb require File.dirname(__FILE__) + ''/../../spec_helper'' class DummyController < ApplicationController def index raise "Prevent index from rendering" end end describe ApplicationController, "Handling errors in production", :behaviour_type =>

I thought that the function eigen(A) will return a matrix with eigenvectors that are independent of each other (thus forming a base and the matrix being invertible). This seems not to be the case in the following example A=matrix(c(1,2,0,1),nrow=2,byrow=T) eigen(A) ->ev solve(ev$vectors) note that I try to get the upper triangular form with eigenvalues on the diagonal and (possibly) 1 just

Hey. The problems with Levinson -type algorithms and integrization are well known. Older codecs have usually solved the problem by using Schur decomposition for inversion of the autocorrelation matrix instead of Levinson. Another solution sometimes used is to use double precision - in this case you probably could code some pseudo-64bit implementation (using only 32bit commands), but that can become quite complex. I would recommend Sc...

With rspec 1.0.8 I can run Test::Unit tests and rspec tests using: rake default and all tests and specs run. With edge rspec the Test::Unit tests return with the message: [list of tests] Finished in 4.5e-05 seconds 0 examples, 0 failures How can I get Test::Unit and rspec to happily co-exist again? Thanks, Alvin

...he SSfol model. When the first two parameters (lKe and lKa) are equal the model degenerates to a different analytic form. If you were to express the corresponding system of ordinary differential equations in the matrix form (as described in Appendix 5 of Bates and Watts (1988)), it would be a Schur triangular block and the special techniques for nondiagonalizable matrices, described in section A5.2 of that appendix, must be used. The clue here is that the first two parameter values are getting very close to each other and this shows up as a singularity. The fitted model is determined by...

I think we all know that the readability of steps isn''t great right now, and in fact there''s a very recent thread that discusses just that. It was that recent thread that prompted me to explore this a bit. The basic idea is that you define step matchers, which have a regex, and then you match step names against that regex. Kind of tough for me to explain so I''ll just
