Client is not accessing second window. Is it possible?

I have an app that opens first window, does a little thing, closes the first window, and opens the second one.

When in the first window, all client APIs work.

But when in the second one, app.client.getHTML('body') throws

  Stack:
    RuntimeError: no such window: target window already closed
    from unknown error: web view not found
        at execute(<Function>) - selectorExecute.js:97:75
        at execute("return !!document.evaluate;") - ensureClientSideSelectorSupport.js:23:17

Is it possible at all to web-drive the second window?

Note that in both cases, app.client.getWindowCount() produces 1, as only one window is open, and app.client.windowHandles() changes as well.

Can a handle be used to redirect client to a new window? Or, something like this.

The unique ID’s are in the values property of app.client.windowHandles() and you can call app.client.window(windowHandleValue) to focus a different window.

Don’t forget we have full access to WebDriver IO methods.

http://webdriver.io/api/protocol/window.html

So you could do this yourself with.

app.client.windowHandles()
  .then((handles) => {
    const windowA = handles.values[0];
    const windowB = handles.values[1];

    // app.client.window(windowA);  <-- Will focus windowA
    // app.client.window(windowB);  <-- Will focus windowB
  });

Most of what spectron does is expose the WebDriver methods and the Electron methods in the same object to make testing ridiculously easy. Lots of the power / methods you are asking for is already part of the WebDriver methods.

app.client.window is not exists…

I can get

[
  'CDwindow-3A94A50FD4E46F979A459297ECFF60D4',
  'CDwindow-4E0C8E41B579F69C850DEC94861CC0B3'
]

from const handles = await this.app?.client?.getWindowHandles();

but how to get actual window handle, and do window.$(selector)?
