'testthat'，我应该如何解释此失败？

Question

我想使用'testthat'将测试添加到我的程序包中。

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在单独的助手中定义。R文件：

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), "'"))
  })
}

执行程序时，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，我仍然会失败1次。但是，两个异常均已正确处理。

我应该如何处理此失败？

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

所有测试都给出了预期的结果，但随后增加了1个失败。我仍然没有看到任何指示原因。

有帮助吗？

将文件“ testthat.R”从“ / tests / testthat”目录移动到“ / tests”目录后，再也没有检测到故障。
