去版本:1.18.1
假设我写了这个测试文件parallel_test.go
package parallel_json_output
import (
"fmt"
"testing"
"time"
)
func TestP(t *testing.T) {
t.Run("a", func(t *testing.T) {
t.Parallel()
for i := 0; i < 5; i++ {
time.Sleep(time.Second)
fmt.Println("a", i)
}
})
t.Run("b", func(t *testing.T) {
t.Parallel()
for i := 0; i < 5; i++ {
time.Sleep(time.Second)
fmt.Println("b", i)
}
})
}
跑步后go test parallel_test.go -v -json,我得到了
{"Time":"2022-06-11T02:48:10.3262833+08:00","Action":"run","Package":"command-line-arguments","Test":"TestP"}
{"Time":"2022-06-11T02:48:10.3672856+08:00","Action":"output","Package":"command-line-arguments","Test":"TestP","Output":"=== RUN TestP\n"}

{"Time":"2022-06-11T02:48:10.3682857+08:00","Action":"output","Package":"command-line-arguments","Test":"TestP/a","Output":"=== RUN TestP/a\n"}

{"Time":"2022-06-11T02:48:10.3702858+08:00","Action":"pause","Package":"command-line-arguments","Test":"TestP/a"}
...
看看这一行{"Time":"2022-06-11T02:48:11.3352891+08:00","Action":"output","Package":"command-line-arguments","Test":"TestP/b","Output":"a 0\n"}。此输出应按案例TestP/a而不是打印b,但输出在并行测试中弄乱了案例名称。
这个问题使报告工具生成错误的 HTML 报告,IDE(如 GoLand)也受到影响,无法正确排序并行输出。
我在 Github here中发现了一个问题,但是这个问题似乎已经在 go 1.14.6 中得到修复,但是,它仍然出现在 go 1.18 中。我想知道发生了什么以及如何处理它,非常感谢。
