使用test_package中的filter参数跳过测试 [英] Using filter argument in test_package to skip tests

问题描述

我想在R CMD check期间运行我的包装单元测试，但是跳过需要Internet连接的测试.按照惯例，所有需要Internet的单元测试都在文件名中使用单词network.

I would like to run my package unit tests during R CMD check, but skip tests that require an internet connection. By convention, all unit tests that require internet have the word network in their filename.

因此我的run-all.R包含:

library(testthat)
test_package("mypackage", filter="^((?!network).)*$")

但是这会给出invalid regular expression错误.如何指定filter自变量，以便它运行除包含单词network的单元测试以外的每个单元测试?

However this gives an invalid regular expression error. How do I specify the filter argument such that it runs each unit test except the ones with the word network in them?

推荐答案

使用invert参数:

test_package("mypackage", filter="network", invert=TRUE)

invert参数最终通过test_check-> run_tests-> test_dir->等通过...参数转发到grepl.从?test_dir:

The invert argument eventually gets forwarded to grepl via the ... argument via test_check -> run_tests -> test_dir -> etc. From ?test_dir:

...:传递给"grepl"的其他参数以控制过滤.

...: Additional arguments passed to 'grepl' to control filtering.
