Description

Considering that this is an ecosystem page that showcases all products/ services that complement selenium based testing, I think that LambdaTest is a fitting example of this category. It is similar to most of the products listed here as well.

Hey @nikhil-lambda,
Why is this going into the "Commercial Training" section? Shouldn't it be the "Functional Test Services" section?
