在我的 Elixir/Phoenix 应用程序中，当我运行时

mix test

我得到如下输出：

$ mix test
....

Finished in 0.09 seconds
4 tests, 0 failures

每个成功的测试都带有点。

如何输出成功的测试名称？

在带有 rspec 的 Rails 中，我曾经使用目录中的 .rspec 文件来执行此操作，如下所示：

$ cat .rspec
--color
-fd
--tty

Elixir 中是否有等价物？

要打印通过测试的名称，您可以将--trace参数传递给mix test. 例如，这是packagemix test --trace的当前 master 分支的输出：httpoison

$ mix test --trace

您还可以通过更改以下ExUnit.start行来将此选项默认设置为 true test_helper.exs：

ExUnit.start(trace: true)

如果您想要完全自定义的输出，您可以实现自己的格式化程序（参见https://github.com/elixir-lang/elixir/blob/master/lib/ex_unit/lib/ex_unit/cli_formatter.ex的示例；这就是默认格式化程序）并配置 ExUnit 以使用它：

ExUnit.start(formatters: [YourFormatterModule])

--trace是您正在寻找的选项：https ://hexdocs.pm/mix/Mix.Tasks.Test.html

希望有帮助！
