Question

在我的Elixir / Phoenix应用程序中，当我运行时

mix test

我输出如下：

$ mix test
....

Finished in 0.09 seconds
4 tests, 0 failures

每个测试成功的点。

如何输出成功的测试名称？

在使用rspec的Rails中，我曾经在目录中使用.rspec文件执行此操作：

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

Elixir中是否有相同的物质？

要打印通过测试的名称，可以将--trace参数传递给mix test。例如，这是mix test --trace包的当前主分支上httpoison的输出：

$ mix test --trace

您还可以通过更改ExUnit.start中的test_helper.exs行来将此选项设置为true：

ExUnit.start(trace: true)

如果您想要完全自定义输出，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以获取示例;这是默认格式化程序）并配置ExUnit以使用它：

ExUnit.start(formatters: [YourFormatterModule])

Answer 2

@Override public View getView(int postion, View convertView, ViewGroup parent) { }是您正在寻找的选项：https://hexdocs.pm/mix/Mix.Tasks.Test.html
