如何让Elixir混合测试输出更加冗长？

Question

在我的仙丹/凤凰的应用程序，当我运行

mix test 

我得到这样的输出：

$ mix test 
.... 

Finished in 0.09 seconds 
4 tests, 0 failures 

与该成功每个测试点。

如何输出成功的测试名称？

在使用RSpec我用在目录中的文件.rspec看起来像这样做的Rails：

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

是否有药剂的相同呢？

要打印通过测试的名称，您可以将--trace参数传递给mix test。例如，这里有mix test --trace上httpoison包的当前主分支输出：

$ mix test --trace

您也可以此选项默认情况下，通过改变ExUnit.start线test_helper.exs设置为true：

ExUnit.start(trace: true) 

如果要完全自定义输出，您可以实现自己的格式化程序（请参阅https://github.com/elixir-lang/elixir/blob/master/lib/ex_unit/lib/ex_unit/cli_formatter.ex作为示例;这是默认格式化程序），并配置ExUnit以使用它：

ExUnit.start(formatters: [YourFormatterModule])

--trace是你要找的选项：https://hexdocs.pm/mix/Mix.Tasks.Test.html
