如何运行软件包的测试

对于给定的已安装软件包,如何运行其testthat测试?我不是已安装软件包的开发人员,而是用户。我只想运行其测试套件以确认其测试在我的环境中通过。我尝试过test_checktest_package,但看到错误。

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,以便对其进行调试。

R不会安装默认测试的测试。为此,请尝试:

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

然后,或者:

testthat::test_package('eplusr')

或使用内置的testInstalledPackage

tools::testInstalledPackage('eplusr')

您不能(除非您按照Brodie的回答重新安装覆盖默认的行为)。

这是设计缺陷^选择。 where = compose(pluck(0), filter(get(1)), enumerate) where.__doc__ = """some docstrings here""" 尽其所能决定通过在http://{GIT_ID}:{GIT_PASSWORD}@{REPOSITORY}.git 目录中强制放置默认安装测试。 R提供了一个覆盖它的选项(如图所示),该选项通常未打开。因此陷入困境。

当然,testthat一直在tests/以下进行测试,正确地做到了。因此,如果软件包使用RUnit,则安装后即可运行其测试。无需重新安装它。
