Last winter in 2017, we—Marc and Kent, QA engineers from LINE Taiwan office—had an opportunity to attend one of the most well known software testing conferences in Europe called Agile Testing Days 2017 in Potsdam, Germany. Agile Testing Days or ATD has been hosting this conference every year for almost a decade and the community grows each year. It was a four full day conference with over 600 attendees, 160 sessions and 130 speakers. The conference week was jam-packed, that at times there were at most 8 parallel on-going sessions, which makes it difficult for us to decide on which track to attend because there were so many interesting topics.
