go test 命令是好的，支持去像一个真正的现代语言，内置支持测试。但是它的输出明显不友好。
$ go test
PASS
ok pragprog.com/rggo/interacting/todo 0.100s
我们可以用以下方法让它变得更漂亮一些-v
$ go test -v
=== RUN TestAdd
--- PASS: TestAdd (0.00s)
=== RUN TestComplete
--- PASS: TestComplete (0.00s)
=== RUN TestDelete
--- PASS: TestDelete (0.00s)
=== RUN TestSaveGet
--- PASS: TestSaveGet (0.00s)
PASS
ok pragprog.com/rggo/interacting/todo 0.211s
但仍不太适合人类使用。
有一个gotestfmt 的工具，它的效果相当不错!只要你把json的输出传给它go test
$ go test -v -json | gotestfmt
📦 pragprog.com/rggo/interacting/todo
✅ TestAdd (0s)
✅ TestComplete (0s)
✅ TestDelete (0s)
✅ TestSaveGet (0s)
但是，如果你有来自测试的stderr输出作为设置/删除过程的一部分，那么gotestfmt 会让你失望。由于某些原因，它在任何测试结果之前输出所有这些输出。
$ go test -v -json | gotestfmt
📦 pragprog.com/rggo/interacting/todo/cmd/todo

这绝对是个小问题；但它让我很恼火，以至于想做点什么。
既然go test 很好地提供了json输出，那么直接使用它呢？
$ go test -v -json

肯定是可以使用的!而且输出的顺序是正确的，所以gotestfmt 把它们分组就更奇怪了。
一个gotestfmt 替换使用jq
jq-go-tests是一个gotestfmt ，使用jq 和sed ，以获得一些人类友好的东西，但仍然正确排序。它不像gotestfmt 那样花哨地拉出包和格式化，但对我来说已经足够好了:
$ go test -v -json | jq-go-tests
Building tool...
Running tests...
✅ TestTodoCLI (0.24s)
✅ TestTodoCLI/AddNewTaskFromArguments (0.22s)
✅ TestTodoCLI/AddNewTaskFromSTDIN (0.00s)
✅ TestTodoCLI/ListTasks (0.00s)
✅ TestTodoCLI/CompleteTask (0.01s)
PASS
Cleaning up...
ok pragprog.com/rggo/interacting/todo/cmd/todo 0.822s
如果你不想点击进入代码，jq-go-tests 是简单的: mn
#!/usr/bin/env bash
jq -r '.Output // ""' | rg -v "=== RUN" | sed -e '/^$/d' -e "s/--- PASS/✅/" -e "s/--- FAIL/❌/"
我可以花一些时间让jq 做更多的工作和格式化，但这绝对已经足够好了，我已经用它作为我的默认测试输出。
