[英]How to run a package's testthat tests
For a given installed package, how do I run its testthat tests?对于给定的安装包,我如何运行它的 testthat 测试? I'm not a developer of the installed package, I'm a user.我不是安装包的开发者,我是用户。 I just want to run its test suite to confirm its tests pass in my environment.我只想运行它的测试套件以确认它的测试在我的环境中通过。 I've tried test_check
and test_package
but I see errors.我试过test_check
和test_package
但我看到了错误。
To be more specific, I know its test suite fails and I want to run the tests in an interactive R session so I can debug it.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,以便我可以调试它。

R doesn't install the testthat tests by default. R 不安装默认情况下测试的测试。 To do so try :为此,请尝试:
install.packages('eplusr', INSTALL_opts="--install-tests", type='source')
Then, either:然后,要么:
testthat::test_package('eplusr')
or alternatively using the built-in testInstalledPackage
:或者使用内置的testInstalledPackage
:
tools::testInstalledPackage('eplusr')
You can't (unless you reinstall overriding default behaviour as shown in Brodie's answer).您不能(除非您重新安装覆盖默认行为,如 Brodie 的回答所示)。
It's a design flaw^Hchoice.这是一个设计缺陷^ Hchoice。 testthat
, in all its wisdom, decided to not install tests by default by enforcing the placement in the tests/
directory. testthat
, testthat
,决定通过强制放置在tests/
目录中来默认不安装测试。 R offers an option to override it (as shown) which is generally not turned on. R 提供了一个选项来覆盖它(如图所示),该选项通常不会打开。 Hence the dilemma.因此陷入了困境。
Of course, RUnit
did it correctly all along having tests below inst/
.当然, RUnit
一直在inst/
进行测试, RUnit
一直是正确的。 So if a package uses RUnit
you can run its tests once installed.所以如果一个包使用RUnit
你可以在安装后运行它的测试。 Without having to reinstall it.无需重新安装它。
Edit: 1 1/2 years later, many of us now use the tinytest package which arrived within the last year.编辑: 1 1/2 年后,我们中的许多人现在都使用去年推出的tinytest包。 Among other advantages, also allows very easy testing of installed packages.除其他优点外,还可以非常轻松地测试已安装的软件包。
