Regression Testing with Touca with Pejman Ghorbanzade

<p style="margin: 0in; font-family: Calibri; font-size: 11.0pt;"> Rob and Jason are joined by Pejman Ghorbanzade. They first talk about changes to the format library to enable better compile time errors, and some conference news from CppCon, C++ on Sea and NDC TechTown. Then they talk to Pejman about Touca, a new tool he's created for continuous regression testing.</p> <p style="margin: 0in; font-family: Calibri; font-size: 11.0pt;">  </p> <h3 style= "font-weight: bold; -webkit-font-smoothing: antialiased; font-size: 18px; padding: 0px; margin: 20px 0px 10px 0px; border: 0px initial initial;"> News</h3> <ul style= "padding: 0px 0px 0px 30px; margin: 15px 0px 15px 0px; border: 0px initial initial;"> <li style= "padding: 0px; margin: 0px; border: 0px initial initial;"><a style= "color: #4183c4; text-decoration: none; padding: 0px; margin: 0px; border: 0px initial initial;" href="https://github.com/dfeneyrou/palanteer" target="_blank" rel= "noopener">Palanteer</a></li> <li style= "padding: 0px; margin: 0px; border: 0px initial initial;"><a style= "color: #4183c4; text-decoration: none; padding: 0px; margin: 0px; border: 0px initial initial;" href= "https://www.zverovich.net/2021/06/16/safe-formatting-api.html" target="_blank" rel="noopener">A quest for safe text formatting API</a></li> <li style= "padding: 0px; margin: 0px; border: 0px initial initial;"><a style= "color: #4183c4; text-decoration: none; padding: 0px; margin: 0px; border: 0px initial initial;" href="https://cpponsea.uk/index.html" target="_blank" rel= "noopener">C++ On Sea starting soon</a></li> <li style= "padding: 0px; margin: 0px; border: 0px initial initial;"><a style= "color: #4183c4; text-decoration: none; padding: 0px; margin: 0px; border: 0px initial initial;" href="https://cppcon.org/cppcon-2021-call-for-submissions/" target= "_blank" rel="noopener">CppCon call for submissions</a></li> <li style= "padding: 0px; margin: 0px; border: 0px initial initial;"><a style= "color: #4183c4; text-decoration: none; padding: 0px; margin: 0px; border: 0px i
