Debugging Unit Tests With Jasmine Test Runner
I am currently working on a project that uses Jasmine and Karma, we use the VS taskrunner to run the test with this command line:
cmd.exe /c grunt -b "C:\...\Gruntfile.js" karma
When I try to run the tests from the js files with the Resharper test runner, Jasmine pops up (with a different port than the grunt config) and says no spec found. I understand it looks for a SpecRunner.html file, but we already have the spec in the grunt config. (files array removed for brevity It looks like this:
karma: {
unit: {
options: {
frameworks: ['mocha'],
reporters: ['spec'],
colors: true,
files: [...],
runnerPort: 9876,
browsers: ['PhantomJS'],
//----- set this as true to run karma:unit once
singleRun: true
}
}
},
Is there any way to load the config from this grunt task into the ReSharper test runner?
Thanks!

I got a little further with this by specifying a path to phantomjs.exe, rather than letting the browser pop up.
Now I'm getting an error that the test timed out, looking at this:

you might want to try
https://marketplace.visualstudio.com/items?itemName=vs-publisher-999439.WallabyjsforVisualStudio2015 or
https://marketplace.visualstudio.com/items?itemName=vs-publisher-2795.ChutzpahTestRunnerContextMenuExtension
as they let you choose the port to run yours tests on and click on the line of code you want to debug (just as it it was C# code).
The benefit of Chutzpah is that you can run any part of a Jasmine (etc) unit test as it assume you are doing iterative Test Driven Development. As a side product the unit tests are presented in the ReSharper test runner just like any other unit tests. Resharper only is negligent when it comes to JS/Node/TS world, but you get used to a tool and everything being in place for that tool.
Equally using wallaby to have a tsunami of intellisense at your finger tips.
Also in the json config when you start up a JS unit test project you can fix the port on which your test runner runs - all of this is covered in the Pluralsight course on seamless TDD in JS with Wallaby (sadly an older version), but all tests will be fine in Resharper once done.
