For alerts we already have logic used, need to extract to helpers:

    it("should block any request during action", async () => {
        //Arrange
        await helpers.goToUrlAndLoad(DemoOpenCartSite);
        await page.on("dialog", dialog => {
            console.log(`Alert was detected: '${dialog.message()}'`);
            dialog.dismiss();
        });
