一個更新的測試方案和新的閃亮的框架出現在本周的閃亮的會議。|本周RStudio巴雷特Schloerke閃亮的開發者提供的細節方案,承諾改善測試R閃亮的應用程序。0.1.0 shinytest2版本,在凹口自周三以來,使得自動化測試的web應用程序交互。測試是通過chromote,無頭的Chrome瀏覽器。閃亮的發布會上演講時由顧問Appsilon Schloerke顯示在線與會者包的record_test()函數。顧名思義,這個函數記錄采取的行動在測試瀏覽器和這些行為轉化為代碼。這段代碼可以自動重新運行一個用戶最初的手工活動和檢查結果。在引擎蓋下,shinytest2需要一些快照的應用程序的狀態和使用testthat單元測試包存儲各種價值觀隨著時間的推移。重新運行一個測試時,可以與同期相比的新值。有關shinytest2的更多信息,請查看包的網站。 Also this week, conference host Appsilon unveiled their Rhino framework for building Shiny apps, which the company touts as allowing app creation “like a fullstack software engineer,” according to the package website . “Apply best software engineering practices, modularize your code, test it well, make the UI beautiful, and think about user adoption from the very beginning. Rhino is an opinionated framework with a focus on software engineering practices and development tools.” Rhino includes built-in support for unit tests, end-to-end testing with Cypress, linting, GitHub Action CI, dependency management, and more. Rhino is a new alternative to the current popular framework golem , which was created by the ThinkR R consultancy. One of the major differences between the two is that golem requires a Shiny app to be created as an R package, while Rhino does not. Appsilon presenters said that for some of their client work, they need the option to create an app which is not structured as a package because this offers more flexibility as to file structure. There was some lively discussion in the conference chat about the merits of requiring Shiny apps to be R packages, with some liking the portability and well known structures of a package and others preferring the concept of greater choice. Videos of many of the conference presentations should be available soon on the Appsilon YouTube channel . In a keynote panel closing the conference, RStudio CTO Joe Cheng was asked about the most interesting recent new developments in Shiny. “We have some incredibly cool things that we can’t talk about,” Cheng responded, calling them “a bunch of secret not ready for public disclosure” work underway. When asked by Shiny Developer Series host Eric Nantz if some of that work might be unveiled at rstudio::conf 2022 , Cheng said that was likely. RStudio’s annual conference will be held July 25-28 in Washington, DC, and online.
