Istanbul code coverage checking coverage of my spec files instead of source?

Question

Just starting out with code coverage tools in general but I think I have everything set up correctly. However, Istanbul is generating a coverage report of my spec file rather than the source file?

when I run jasmine-node repeatSpec.js --verbose

I get:

 repeat Start
    repeats strings - 1 ms
  repeat Finish - 3 ms



Finished in 0.004 seconds
1 Tests, 0 Failures, 0 Skipped

which is correct, and if I fail my test on purpose it fails correctly as well.

However, when I run this istanbul command:

 istanbul cover  /d/Users/rkan/AppData/Roaming/npm/node_modules/jasmine-node/bin/jasmine-node  repeatSpec.js

I get this respond, which is checking coverage based on my spec file.

What did I do wrong?

Thanks!

nb - file directory is like this

|
|-lib/repeat.js
|
|-tests/repeatSpec.js
|

repeat.js

if (! String.prototype.repeat) {
        String.prototype.repeat = function (times) {
            return new Array(times+1).join(this);
        }
    }
if (x=68){
    x = 2;
}

if (x=200){
    x =5;
}

repeatSpec.js

require("../lib/repeat.js");

    describe("repeat", function() {
        it("repeats strings", function() {
            expect("abc".repeat(2)).toEqual("abcabc");
            expect("abc".repeat(0)).toEqual("");
        });
    });

Make sure to pass mask: '*.spec.js' option to your istanbul options configurations object.
