I use it to start IIS Express, then run Nunit, and then http://stackoverflow.com/questions/4263401/rake-task-error-handling shutdown the server after Nunit has finished. The problem is that every time Nunit fails, the rake stops, and never gets to the shutdown part. How do I continue a rake after Nunit has failed, and still tell CCNet that Nunit has failed, and thus so has the build? ruby nunit rake cruisecontrol.net share|improve this question asked Feb 28 '12 at 19:30 DrSammyD 475626 How does rake stop? Is there an exception? If yes - catch it. –knut Feb http://stackoverflow.com/questions/9488407/continue-rake-after-failure 28 '12 at 20:12 add a comment| 2 Answers 2 active oldest votes up vote 6 down vote accepted How do you run NUnit from rake? are you using "sh"? This is how you use "sh" to execute shell command, and intercept the result. I just use empty block to ignore any result(failed or success) sh "your shell command" do |ok,res| #empty block to ignore any failed or success status #in your case set failed flag based on ok parameter nunitSuccessFlag=false #hardcoded for sample; must set true or false based on ok parameter end put this raise exception after shutting down the server so ccnet knows that build failed raise "NUnit failed" if nunitSuccessFlag == false alternative: use try catch block as stated by user knut above as shown in this link: Rake Task: error handling (shut down the server in the ensure block) share|improve this answer edited Feb 29 '12 at 5:05 answered Feb 29 '12 at 4:39 kite 715819 Yep, I was using sh. Thanks. –DrSammyD Feb 29 '12 at 15:04 add a comment| up vote 1 down vote I used this to make rake ignore the status returned from the command: sh "the command || true" true always exits without an error, making sh always see a success. share|improve this answer answered Jun 19 '15 at 21:39 zanedp 16614 add a comment| Your Answer draft saved draft discarded Sign up or log

Each task may be either one of the built-in types, or a block of your own Ruby code. It was originally created to handle software build processes, but the combination of convenience and flexibility that it provides has made it the standard method of job automation for Ruby projects. Writing Rake Tasks You may use supplied methods in your task code to conveniently set up common jobs, such as running test suites, publishing files and packaging software. Equally, you may call or write any other Ruby code into a Rake task, which means that it can automate just about anything. Crucially, you also write the task and dependency definitions themselves in Ruby, following a specific format. This means that you do not need to deal with any new syntax to start automating your routine jobs. Anyone with a basic knowledge of Ruby can
