我正在使用 testthat 来测试我的 R 包(https://github.com/beerda/hexmatrix)。最近,我开始了 C++ 测试:我已经执行testthat::use_catch()
了,它应该设置包以使用 C++ Catch 进行单元测试,然后我编写了一些测试。如果由 执行,测试将正确运行devtools::test()
。但是,如果我尝试运行R CMD check
or devtools::check()
,我会收到以下错误消息:
Running ‘testthat.R’ (1.8s)
Running the tests in ‘tests/testthat.R’ failed.

xml2 包已安装,rlang::check_installed("xml2") 返回 TRUE。
不确定它是否以某种方式连接:当我尝试手动执行命令run_cpp_tests("hexmatrix")
时,出现以下错误:
Error in read_xml.raw(charToRaw(enc2utf8(x)), "UTF-8", ..., as_html = as_html, :

请问有人知道出了什么问题吗?提前致谢。
