如何在 Bazel 输出中获取所有任务结果
How to get all task results in Bazel output
我在 CI 中 运行ning Bazel（通过 Bazelisk）并努力从构建中获得合理的输出。我希望在输出中看到 all 测试 and/or 目标的结果（即使它们是由缓存完成的）这样开发人员就可以确定他们拥有的东西写的正在测试中。
最明显的事情是设置 --show_task_finish 标志，但不幸的是 that flag doesn't seem to work。我还没有找到任何可以可靠地打印出测试或目标结果的标志。不幸的是，我无法从通过的测试中打印 stdout/stderr，因为它们会生成太多输出。
例如，如果我想确保测试了特定目标，我最近遇到的一些稍微编辑过的输出几乎完全没用：
bazel test //...

对--test_summary使用默认值short给出所有目标：

--show_result=1000000 将显示所有目标（使数字尽可能大以包含所有目标）。不过，这往往会产生很多输出。另请注意，对于测试，它表示测试二进制文件已构建，而不是 运行.
--test_summary=short是打印每个测试信息的方式。
build event protocol 提供了您需要的所有数据。
BuildBuddy 等工具可以为您可视化构建事件协议。

--show_result=1000000 将显示所有目标（使数字尽可能大以包含所有目标）。不过，这往往会产生很多输出。另请注意，对于测试，它表示测试二进制文件已构建，而不是 运行.
--test_summary=short是打印每个测试信息的方式。
build event protocol 提供了您需要的所有数据。
BuildBuddy 等工具可以为您可视化构建事件协议。

BuildBuddy 显示例如所有测试以及相应的测试结果。您可以单击每个单独的测试并查看相应的日志：
Build Event Protocol 提供直播。这样谁可以为您的开发人员提供实时 build/test 信息。
