根因分析

在 -race 下运行的测试启动了共享状态且无同步的 goroutine，竞争检测器中止了测试二进制。

English

A test running under -race spawns goroutines that share state without synchronization, and the race detector aborts the test binary.

    var wg sync.WaitGroup
wg.Add(1)
go func() { defer wg.Done(); mutateShared() }()
wg.Wait()

    go test -race -run TestFoo ./...
// read the two conflicting stacks and add a mutex around both

无效尝试

常见但无效的做法:

  1. 80% 失败

    Shuffling changes timing but the unsynchronized access remains and the race recurs.

  2. 75% 失败

    The race is inside the test's own goroutines, not between tests, so serializing tests does not help.
