Alert windows are widely used across websites where an alert message acts as a mode to ‘interrupt’ the current flow of the user journey. A simple example of a JavaScript alert would be someone filling in details on the sign-up page and submitting the details without entering some mandatory information. This user flow also needs to be verified when Selenium automation testing is performed on the web product. 

Handling pop-ups and alerts are one of the common test scenarios that should be tested using Selenium WebDriver. In this post of the Selenium Python tutorial series, we look at how to handle JavaScript alerts in Python. It is worth mentioning that the core fundamentals of JavaScript alerts and popups remain unchanged irrespective of the programming language used for Selenium.

In the early days of software development, anyone seeking to develop a web, mobile, or backend application had to own the hardware required to run a server, which is an expensive process.

Then, when cloud computing came, it became possible to lease server space or a number of servers remotely. The developers and companies who rent these fixed units of server space generally overbuy to ensure that a spike in traffic or activity won’t exceed their monthly limits and break their applications. Because of this, a lot of the server space that gets paid for can be wasted.

A combination of AWS Lambda and Amazon API Gateway is a widely-used architecture for serverless microservices and API-based solutions. They enable developers to focus on their applications, instead of spending time provisioning and managing servers.

API Gateway is a feature-rich offering that includes support for different API types (HTTP, REST, WebSocket), multiple authentication schemes, API versioning, canary deployments, and much more! However, if your requirements are simpler and all you need is an HTTP(S) endpoint for your Lambda function (for example, to serve as a webhook), you can use Lambda Function URLs! When you create a function URL, Lambda automatically generates a unique HTTP(S) endpoint that is dedicated to your Lambda function.
