[英]r testthat and covr use in a non-package library
I'd like to be able to use testthat
and covr
in a project that is not an r package. 我希望能够在一个不是 r包的项目中使用
testthat
和covr
。 In fact does not use any third party services. 实际上不使用任何第三方服务。 Just a collection of plain-old-r source files
只是一个普通的r源文件的集合
I am struggling to find out if this is possible, and if so, the instructions on how to set this is up. 我正在努力找出这是否可能,如果是这样,关于如何设置它的说明已经完成。
What I have found assumes you are writing an r package. 我发现的假设你正在写一个r包。 I like to avoid this overhead.
我喜欢避免这种开销。
Prior Art: 现有技术:
That should be possible without problems. 这应该没有问题。
First : I have one file with code that should be tested named code.R
: 第一 :我有一个代码的文件,应该测试名为
code.R
:
f1 <- function(n, ...) {
rnorm(n = n, ...)
}
Second : Then I have a file with tests named tests.R
: 第二 :然后我有一个名为
tests.R
测试文件:
source("code.R")
test_that("Random tests", {
tmp1 <- f1(10)
expect_type(tmp1, "double")
expect_equal(length(tmp1), 10)
})
Third : And then you can run tests as well as coverage like this: 第三 :然后你可以像这样运行测试和覆盖:
library(testthat)
library(covr)
test_file("tests.R")
res <- file_coverage("code.R", "tests.R")
res
report(res)
Multiple files should be no problem. 多个文件应该没问题。
