运行R CMD检查时未找到R包测试

Question

我正在使用该testthat包为我的R包编写测试.我已按照http://r-pkgs.had.co.nz/tests.html上的说明进行操作(我相信).我用了

devtools::use_testthat()

设置测试骨架.我已经创建了一个测试文件,tests/testthat文件名以test.当我devtools::test()在RStudio中运行或按Ctrl + Shift + T时,测试运行成功,但是当我运行R CMD check或Ctrl + Shift + E时,testthat找不到我的包.我收到了错误

> library(testthat)
> 
> test_check("foo")
Loading required package: foo
Error in loadNamespace(name) : there is no package called 'foo'
Calls: test_check ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous>
In addition: Warning message:
In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE,  :
  there is no package called 'foo'
Execution halted

我通过R_LIBS_SITE在我的.Renviron文件中设置来修改我的库路径.我怀疑这在跑步时没有被阅读R CMD check,但我认为它不应该有所作为.

当我devtools::check()从RStudio控制台运行时,它成功完成(包括测试),但运行Check in RStudio失败.

我添加了一些调试来testthat.R打印出来.libPaths()和其他位:

> library(testthat)
> .libPaths()
[1] "C:/Users/timk/AppData/Local/Temp/Rtmp841w0b/RLIBS_1790551706"
[2] "C:/Program Files/R/R-3.2.2/library"
> list.files(.libPaths()[1])
 [1] "KernSmooth" "MASS"       "Matrix"     "boot"       "class"

[11] "lattice"    "magrittr"   "memoise"    "mgcv"       "nlme"
[16] "nnet"       "praise"     "rpart"      "spatial"    "stringi"
[21] "stringr"    "survival"   "testthat"
> list.files(file.path(.libPaths()[1], "foo"))
character(0)
> list.files(file.path(.libPaths()[1], "testthat"))
 [1] "CITATION"    "DESCRIPTION" "INDEX"       "LICENSE"     "MD5"
 [6] "Meta"        "NAMESPACE"   "R"           "help"        "html"
[11] "libs"

您可以看到包目录是在临时库中创建的,但包是空的.将其与文件列表进行比较testthat.

我也尝试下载另一个使用testthat(anonymizer)的软件包并得到同样的错误.

Answer 1

尝试testthat在Suggests:字段中添加DESCRIPTION。R CMD CHECK 将仅在检查期间将该文件中提到的包放入范围内。
