it('waitForWindowCount should wait for window window number increase and decrease', async () => {
        const actionPage: ActionsPage = new ActionsPage();
        await openUrlInNewTab(actionPage.url);
        await waitForWindowCount(2);

        await expect(getWindowHandlesCount()).toBe(2);

        await closeWindow(1);
        await waitForWindowCount(1);

        await expect(getWindowHandlesCount()).toBe(1);
    });
});
