Join us for the fifth annual Testing and Verification Symposium where we'll aim to bring together the academia and industry communities in an open environment to exchange ideas and showcase the top experts from testing and verification scientific research and practice. Taking place virtually again this year from Wednesday, December 1 - Thursday, December 2, the symposium is open to all testing and verification practitioners and researchers and is free to attend. Last year, the virtual 2020 Symposium garnered a global audience of over 400 people. We invite you to register and attend the 2021 Symposium through this event site. To connect with fellow attendees and members of the testing and verification broader community, join our TAV Symposium group.
