QUALITY ASSURANCE: Exploratory Bug Testing
“Working with Testbirds led to us professionalising our testing process, as it forced us to critically examine our own testing structure. It definitely made our organisation more mature in that respect. Furthermore, crowdtesting has proven to be efficient. We can start testing on a Monday and see the results on Tuesday. It’s a powerful addition to our development process.”

Lieven Swinnen, Manager e-Business Landal GreenParks
