Question

使用Selenium Server 3.4.0和Gecko Driver v0.18时，此Rselenium命令可以正常工作。

remDr$setImplicitWaitTimeout(milliseconds = 15000)

这是相关的代码块：

remDr <- remoteDriver()
remDr$open(silent = TRUE)   
remDr$setImplicitWaitTimeout(milliseconds = 15000)

但是当使用Gecko v0.18或v0.19运行Selenium Server 3.5.3时，相同的代码会生成此错误：

Selenium message:POST /session/91a1f43f-18b3-4e11-92a9-d738cd4049a4/timeouts/implicit_wait did not match a known command

Firefox：55.0.3（64位）

我已经在Rselenium Github回购中查找了软件包更新，并搜索了其他信息。

不确定我是否遗漏了某些内容或应该报告错误。

Answer 1

隐式等待的实现现在略有不同。尝试

remDr <- remoteDriver()
remDr$open()
remDr$setTimeout(type = "implicit", milliseconds = 5000)

您可能还希望设置页面加载超时

remDr$setTimeout(type = "page load", milliseconds = 5000)

Answer 2

SetTimeouts命令映射到Marionette setTimeouts命令，这使得geckodriver与Firefox 56及更高版本兼容。

来自他们在github上的发布信息。你应该使用firefox 56或更高版本而不是55。
