What is the best way to check TypeScript + browsersify files using jasmine?

I have a collection of TypeScript files that I merged into a single file called bundle.js using browsersify and tsify in my gulp build process.

Now, I have the original .ts files in the /src directory and the compiled bundle.js in the /build directory.

I want to test this setup using jasmine and karma, but I'm facing some challenges. Jasmine seems unable to use the .ts files or the final build.js. Additionally, I'm not sure how code coverage would work with this technology stack.

Can anyone provide tips on how to run jasmine tests in this scenario and what the architecture should look like?

Thanks

---- Edit-----

I attempted to include the build.js file in my Karma configuration:

files: [
    'build/**/*.js',
    'spec/**/*.spec.js'
]

However, I'm unsure how to access objects within it. For example, I have a TypeScript class called "Unit", but Browsersify appears to encapsulate it inside an anonymous function like this:

var Unit = (function () {
    function Unit() { 
    }
    return Unit;
}()); 

Unfortunately, I can't seem to access the "Unit" class from the outside, resulting in an error when trying to instantiate it in Jasmine:

ReferenceError: Can't find variable: Unit

Answer №1

To run your tests, make sure to load the bundle.js containing them using karma and the Karma-jasmine module. If you're interested in coverage reports, don't forget to generate source maps for your bundle.js. Once the tests are done, utilize the remap-istanbul module to generate coverage data specifically for your typescript files.
