如何在模块中单元测试功能？

Question

I'm new to a project where there is a JavaScript script a3.panel.js written by someone else. It defines an module like this:

a3.panel = (function () {
    let property1 = {},
        property2 = $('.checkbox');

    function someMethods () {
        some logic
    };

    return ({
        some value
    });
})();

with Jasmine, how can I test the method inside this module? I tried

describe("panel test", () => {
    it("should test", () => {
        var panel = a3.panel;
        expect(typeof a3.panel.property1).toBe("object");
    });
}); 

and Jasmine returns:

ReferenceError: a3 is not defined

Answer 1

I guess the external library is not loaded for the test.

Can you try this in your Jasmine test (I haven't tried yet)-
document.write('<script src="http://.../a3library.js></script>')

You may provide local path too.

OR

Use jQuery GetScript

And

Check this too - include external Javascript as a source to Jasmine
