Testing your Typescript code using Visual Studio's unit testing tools

I've spent the last couple of days trying to figure out how to test Typescript in Visual Studio, but I'm encountering some difficulties. Despite attempting various frameworks, I can't seem to get it to work in a separate project. Can anyone offer suggestions on how to successfully run these tests in a different project? Should I consider creating a web interface for this purpose?

Appreciate any assistance you can provide.

Answer №1

Unit testing frameworks for TypeScript are commonly executed via the command line.

To seamlessly incorporate these frameworks into Visual Studio, consider utilizing a Task Runner such as Gulp.

Once your gulpfile.js is configured to run the tests, you will be able to view them in the "Task Runner Explorer" window in Visual Studio by pressing CTRL + ALT + Backspace.

You can automate a task to run every time you build your solution by right-clicking it in Task Runner Explorer and choosing "Bindings -> After Build".

Here's an example of a Gulp file for Karma:

/// <binding AfterBuild='test' />
var gulp = require('gulp');
var Server = require('karma').Server;

gulp.task('test', function (done) {
  new Server({
    configFile: __dirname + '/karma.conf.js',
    singleRun: true
  }, done).start();
});
