R testthat_result 保存在文件中

Question

我正在嘗試保存由“testthat”package 結果生成的單元測試結果

如何將“testthat_result”object 的測試結果保存到文件中（txt 或 csv 文件）

library(testthat)
result<-test_file('utils_test.R', reporter = "minimal")

outfile<-file("output.txt")
writeLines(c(result), outfile)
close(outfile)

但這不起作用

Answer 1

問題是您的結果 object，這是一個列表。

library(testthat)
path <- testthat_example("success")
result<-test_file(path, reporter = "minimal")
str(result)

在使用 writeLines 保存之前，您需要將其轉換為字符 stream。

str(result)
