Founded by Jessie & Jon McGreevy in 2018, Test-42 aims to help testers to improve their testing skills, while also focusing on the users needs and experience.


Test-42 is a family-run company specialising in user-focused exploratory testing. Combining Jon’s 10 years+ in the industry with Jessie’s fresh take on testing, we deliver training that empowers testers to provide lean and powerful functional testing, while always keeping the end-user’s experience in mind.

There is also Hiccup, who doesn’t provide much on the testing front, but he does provide plenty of kisses and cuddles to help with morale.
