Help needed for gettting started.

Does chrome.extension.onConnect work? I'm not doing extension development anymore but looking at the docs I don't see the onConnect attribute https://developer.chrome.com/extensions/extension

I believe you're supposed to use runtime for this now.

@clarkbw Thank you quick response. Actually I am using runtime now. Still I am not sure How to test my function. Can you provide some details please?

[clarkbw]

I'd probably do something like this:

describe('your function to test', () => {
  it('should have called a webextension API', () => {
    expect(chrome.extension.onConnect.addListener).toHaveBeenCalled();
    expect(chrome.tabs. query).toHaveBeenCalledWith({ active: true });
  });

If you wanted to test the port.onMessage.addListener pieces I think you'd have to submit a PR that allows for that kind of testing as well. Currently we don't return a port object you can work with.

Thank you @clarkbw . It makes sense now.
Suppose If I want to test

 port.onMessage.addListener(function (message) {
        switch (message.type) {
             case 'reloadWithDebug':
                                 case 'reloadWithDebug':
            // This is called even for iframe is loaded
            chrome.tabs.query({
              active: true,
              lastFocusedWindow: true
            }, function(tabs){
              let currentUrl = tabs[0].url;
                chrome.tabs.update({url:currentUrl});
               }
}

Is there a way to pass a message manually to the listener and check if chrome.tabs.update is called? What is the best way to approach this?
