Hi everyone, Iâm working on a new plugin for Nautilus/Calypso that will help us with the test. The goal is to provide us the selection of tests we should run after a modification. It would be great if you accept to try it or want to use it. Currently, by installing the plugin, when you select a method in Calypso or Nautilus, you will see a new critique that will offer you to run the test relative to the method youâve selected (or class ^^ ) Another goal is to calculate the efficient of this new tool and how we will use it. Itâs why Iâve also developed a plugin that will record how we will use the plugin. If you accept to help me. Please tell me ( so i will be able to estimate how many data I will obtain ). Now the commands. If youâd like to help me. The command is simple : Metacello new smalltalkhubUser: 'badetitou' project: 'TestsUsageAnalyser-CoraExtends'; configuration: 'TestsUsageAnalyser_CORAExtends'; version: #stable; get; load. If youâd like to use the plugin or just want to try it. Itâs also simple Metacello new smalltalkhubUser: 'badetitou' project: 'CORA'; configuration: 'CORA'; version: #stable; get; load. For the version with Calypso ( because itâs cool ). Metacello new smalltalkhubUser: 'badetitou' project: 'CORA'; configuration: 'CORA_Calypso'; version: #stable; get; load. So, if you want to help me and use calypso you should run the first and the third command. Options for the plugin are available in the settings of Pharo in the group : âTestRegressionâ. So you can extend the plugin with your own logic of testing strategy. To disable the spy (first package) in the option please uncheck âTest Usage Analyserâ Iâm going to write a blog post that will explain all the plugin and how to use it. If you find bugs ( But there are no bugs ;) ) please tell me and i will fix it as soon as possible. If youâd like that I add a feature, tell me too. Thanks a lot for your help. Benoît Verhaeghe
