如何运行测试包的测试

Question

对于给定的已安装软件包,如何运行其测试测试？我不是已安装软件包的开发人员,我是用户.我只是想运行它的测试套件来确认它的测试在我的环境中通过.我试过了test_check,test_package但我看到了错误.

更具体地说,我知道它的测试套件失败了,我想在交互式R会话中运行测试,所以我可以调试它.

> require(eplusr)    # choice of package unimportant. Any using testthat will do.
Loading required package: eplusr
> require(testthat)
Loading required package: testthat
> test_check("eplusr")
Error in test_files(paths, reporter = reporter, env = env, stop_on_failure = stop_on_failure,  : 
  No matching test file in dir
> test_package("eplusr")
Error: No tests found for eplusr

Answer 1

R默认情况下不安装testthat测试.为此,请尝试:

install.packages('eplusr', INSTALL_opts="--install-tests", type='source')

然后,要么:

testthat::test_package('eplusr')

或者使用内置的testInstalledPackage:

tools::testInstalledPackage('eplusr')

Answer 2

你不能(除非你重新安装覆盖默认行为,如Brodie的回答所示).

这是一个设计缺陷^ Hchoice. testthat尽管如此,他决定不通过强制执行tests/目录中的位置来默认安装测试.R提供了一个覆盖它的选项(如图所示),通常不会打开它.因此进退两难.

当然,RUnit下面的测试一直都是正确的inst/.因此,如果包使用,RUnit您可以在安装后运行其测试.无需重新安装.
