Execute JavaScript from within a C# assembly
- by ScottKoon
I'd like to execute JavaScript code from within a C# assembly and have the results of the JavaScript code returned to the calling C# code.
It's easier to define things that I'm not trying to do:
I'm not trying to call a JavaScript
function on a web page from my code
behind.
I'm not trying to load a WebBrowser
control.
I don't want to have the JavaScript
perform an AJAX call to a server.
What I want to do is write unit tests in JavaScript and have then unit tests output JSON, even plain text would be fine. Then I want to have a generic C# class/executible that can load the file containing the JS, run the JS unit tests, scrap/load the results, and return a pass/fail with details during a post-build task.
I think it's possible using the old ActiveX ScriptControl, but it seems like there ought to be a .NET way to do this without using SilverLight, the DLR, or anything else that hasn't shipped yet. Anyone have any ideas?

Clarification:
We have unit tests for our JavaScript functions that are written in JavaScript using the JSUnit framework. Right now during our build process, we have to manually load a web page and click a button to ensure that all of the JavaScript unit tests pass. I'd like to be able to execute the tests during the post-build process when our automated C# unit tests are run and report the success/failure alongside of out C# unit tests and use them as an indicator as to whether or not the build is broken.
