Diego is a Software Engineer in Test who initially worked only in development without so much focus on testing. After some time he realised the importance of testing during the development cycle and started to do automation testing for APIs and messaging-type systems. UI/Web testing got his attention later, where he got involved in writing Selenium tests and also setting up Selenium Grid infrastructures. In his current job, he uses what he has learnt to help other teams find good ways to test the software being developed. Diego also builds tools for testing (like Zalenium), which can simplify the infrastructure setup that other teams need to do before starting to implement tests.
