This code provides functions to control browser windows and tabs, with the primary purpose of ensuring that only a single window remains open after a series of actions. It achieves this by closing all other windows and tabs, leaving a designated window active.

Run example

npm run import -- "only one window"

only one window

var importer = require('../Core');

function closeAllTabs(client, keep) {
    return client
        .getWindowHandles()
        .then(h => {
            var promises = [];
            for(var i = 0; i < h.length; i++) {
                if(h[i] === keep) {
                    continue;
                }
                promises.push((i => resolve => client
                              .switchToWindow(h[i])
                              .then(() => client.close())
                              .then(() => resolve())
                              .catch(e => resolve()))
                              .apply(this, [i]));
            }
            return importer.runAllPromises(promises);
        })
        .catch(e => console.log(e))
}

function closeAllWindows(client, keep) {
    return client
        .getWindowHandles()
        .then(h => {
            var promises = [];
            for(var i = 0; i < h.length; i++) {
                if(h[i] === keep) {
                    continue;
                }
                promises.push((i => resolve => client
                              .switchToWindow(h[i])
                              .then(() => client.close())

                              .catch(e => resolve()))
                              .apply(this, [i]));
            }

        })
        .then(() => client.switchToWindow(keep))
        .catch(e => console.log(e))
}

This code defines functions to manage browser windows and tabs, specifically focusing on ensuring only one window remains open.

Here's a breakdown:

1. closeAllTabs(client, keep):

   • Takes a client object (likely Selenium WebDriver) and an optional keep window handle.
   • Closes all tabs except the specified keep window.

2. closeAllWindows(client, keep):

   • Similar to closeAllTabs, but closes all windows except the specified keep window.

3. onlyOneWindow(client):

   • Opens a new window to Google, then closes all other windows and tabs, leaving only the Google window open.

4. Export:

   • Exports the onlyOneWindow function for use in other modules.
