‘'testthat'，我应该如何解释这个失败？

Question

我想使用'testthat‘将测试添加到我的包中。

这是我的测试文件：

library(RBaseX)

test_that("Credentials are accepted", {
  skip_unless_socket_available()

  expect_error(BasexClient$new("localhost", 1984L, username = "admin", password = "denied"), "Access denied")

  Session <- BasexClient$new("localhost", 1984L, username = "admin", password = "admin")
  expect_equal(class(Session)[[1]], "BasexClient")
})

skip_unless_socket_available在单独的helper.r文件中定义：

skip_unless_socket_available <- function() {
  tryCatch({
    Socket <- socketConnection(host = "localhost", 1984,
                           open = "w+b", server = FALSE, blocking = TRUE, encoding = "utf-8")
    close(Socket)
    TRUE
  }, error = function(e) {
    skip(paste0("basexserver not available:\n'", conditionMessage(e), "'"))
  })
}

当程序执行时，我得到以下输出：

Loading RBaseX
Testing RBaseX
✓ |  OK F W S | Context
✓ |   2       | test_RbaseX [0.2 s]
⠹ |   2 1     | test_RbaseX
══ Results ═══════════════════════════════
Duration: 0.3 s

OK:       2
Failed:   1
Warnings: 0
Skipped:  0

无论我做什么，我还是会失败一次。但是，这两个异常都得到了正确的处理。

我应该如何处理这个失败？

在test_RBaseX.R中插入3个contexts()后，我现在得到以下输出：

Loading RBaseX

所有测试都给出了预期的结果，但随后添加了1个失败。我仍然没有看到任何原因的迹象。

这有帮助吗？

(顺便说一句，感谢这些测试活动，我发现并修复了几个错误：-)

将文件‘testth.R’从‘/test/testthat’目录移到‘/tests’目录后，不再检测到任何故障。
