Web Automation Testing Tools

Browser Automation Tools

Browser or web automation tools come in all shapes and sizes. Last time we counted, there were over a 100 of them, most of which may not cater to your specific needs (unfortunatley). Web automation tools landscape is only overwhelming if you don't have a map to navigate. Here's a simple 3-pronged framework to help you quickly narrow down your best options.

How to choose a "browser automation testing tool" that's best for your specific needs?

Browser automation tool selection is not just about the cost of an automation platform. To profitably succeed in automation, you'll need to take into account the cost of platform setup, customization, maintenance & understand how to execute it with Continuous Integration.

Your Go-To-Market Priority

If you are in a competitive market, you probably need to release new versions of your applications super fast. A 3 to 6 month browser automation project implementation may not work for you.

Open Source Vs. Paid

Open source is what usually comes to mind when most people are getting started with browser automation. Sometimes an open source tool is what you need but not always.

Application Complexity & Scale

Having a browser automation tool that works for a trivial use case is one thing but setting up a platform that can work reliably when you have complex use cases that are scaling with time is an entirely different thing.

Your Go-To-Market Priority

If your go-to-market priority is very high, the last thing you want to do is build entire browser automation script in-house instead of picking up ready made off-the-shelf products with support.

A common mistake that many companies, with homegrown web automation scripts, make when faced with high go-to-market priority is - they try to automate only on the UI layer and ignore unit & API level testing. This creates serious issues downstream resulting in poor customer experience.

Choose your web automation tool keeping your go-to-market priority in mind.

Open Source Vs. Paid

The most popular open source web automation tool is Selenium. If you insist on using an open source tool, it should be on top of your list.

However, keep in mind that an open source web automation tool implementation requires significant upfront time/cost and even more in terms of future enhancements & maintenance.

Speak to at least a few companies in your vertical who have implemented a tool like Selenium in the past and see what they have to say. If they have moved on to a paid tool - ask them about specific reasons for doing so.

The web automation tool you choose today isn't just for your current needs, you want the automation to continue to work without breaking as your product evolves.

Application Complexity & Scale

If you have a fairly complex product, you don't want to spend too much time at the test automation layer writing test automation code. Your team's time is best spent focusing on the complexity of business use cases in the business layer.


A common mistake many automation engineers make when faced with complex web applications is - they try to make automation work using hacks rather than simulating end user interactions. Web automation scripts that are built from scratch (e.g. using Selenium) expose a lot of complexity to automation engineers and dealing with two layers of complexity (tool complexity + application complexity) can be very overwhelming.

I wish I would have found this product sooner. I was able to get our product’s regression tests up and running very quickly. Post running the regression tests against every build now a failure in the log is one that tells me that something has changed a bug has been introduced. Sahi is a time saver.
