问题描述
构建软件包会导致以下警告：
Building a package results in the following warning:
* checking for unstated dependencies in tests ... WARNING
‘library’ or ‘require’ call not declared from: ‘testthat’
* checking tests ...
Running ‘test-all.R’
OK
* checking PDF version of manual ... OK
WARNING: There was 1 warning.
包目录有一个名为的文件夹 ，文件test-all.R：
The package directory has a folder called tests, with a file test-all.R:
library(testthat)
library(bootLR)
test_package("bootLR")
然后一个子文件夹 testthat 其中包含两个保存各种测试的文件。
Then a subfolder testthat with two files in it that hold the various tests.
错误消息可能告诉我，我没有在DESCRIPTION文件中声明testthat，但是我不想要最终用户的安装，我相信将test-all.R文件中的库（testthat）语句放在testthat手册。
The error message is likely telling me that I have not declared testthat in the DESCRIPTION file, but I don't want to require its installation by end-users, and I believe that putting the library(testthat) statement in the test-all.R file comes from the testthat manual.
任何方式，或者我必须以正确的方式添加它（强制使用安装testthat）？
Any way around this, or do I have to add it in the proper way (that forces uses to install testthat)?
编辑：我想添加到建议：可能是最好的方法吗？
I guess adding it to Suggests: might be the best way to do this?
推荐答案
也许建议？ 。
