Jest: Jest 16（实际上也是 Jest 15）没有正确地进行中继集成测试，但 Jest 14 正确地做到了

您要请求一个 _feature_ 还是报告一个 _bug_？

一个错误。

目前的行为是什么？

故意失败的测试由 Jest 16 报告为通过。 Jest 14 正确地未通过测试。

这是 Jest 16 的输出（参见下方 Jest 14 的输出）：

$ npm test

> @ test /Users/macbook/Documents/work/jest-relay-integration-test
> jest

 PASS  __tests__/Me-test-int.js
 PASS  __tests__/SignIn-test.js

Test Suites: 2 passed, 2 total
Tests:       2 passed, 2 total
Snapshots:   0 total
Time:        9.316s
Ran all test suites.

如果当前的行为是一个错误，请提供重现的步骤，如果可能的话，我们可以在 GitHub 上提供一个最小的存储库，我们可以npm install和npm test 。

这是 repro 的 repo。

主分支与 jest 16

jest14 分支与 jest 14

只需克隆它， npm install ，你就会自己看到一切。 使用分支在 Jest 版本之间切换。

什么是预期行为？

预期行为 - 再现中的测试必须失败。 因为它是一个失败的 Relay 集成测试。
这是 Jest 14 的正确输出：

$ npm test

> @ test /Users/macbook/Documents/work/jest-relay-integration-test
> jest

使用--debug再次运行 Jest 并提供它打印的完整配置。
