Question

我正在使用testthat包为我的R包编写测试。我按照http://r-pkgs.had.co.nz/tests.html的说明（我相信）。我用了

devtools::use_testthat()

设置测试骨架。我在tests/testthat中创建了一个测试文件，文件名以test开头。当我在RStudio中运行devtools::test()或Ctrl + Shift + T时，测试成功运行，但是当我运行R CMD check或Ctrl + Shift + E时，testthat无法找到我的包。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

我通过在R_LIBS_SITE文件中设置.Renviron来修改我的库路径。我怀疑在运行R CMD check时没有阅读，但我认为它不应该有所作为。

当我从RStudio控制台运行devtools::check()时，它成功完成（包括测试），但运行Check in RStudio失败。

我向testthat.R添加了一些调试以打印出.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"
 [6] "cluster"    "crayon"     "digest"     "foo"        "foreign"
[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testthat的文件列表进行比较。

我还尝试下载另一个使用testthat（anonymizer）的软件包并收到同样的错误。

Answer 1

尝试在testthat的{{1}}字段中添加Suggests:。 R CMD CHECK只会在检查期间将该文件中提到的包放在范围内。

Answer 2

你似乎忘了这行

library(foo)

在你的testthat文件中。如果我看一些renowned examples，他们会这样做

运行R CMD检查时未找到R包测试
