bazel - 如何减少 bazel 打印？

Question

当我使用 bazel 运行测试时，它会输出如下内容：

endobson@yggdrasil () ~/proj/racket/yaspl2 % ibazel test //libraries/... //tools/...                                                                                                                                                      (3)

这是大量的文本，占据了我笔记本电脑的大部分屏幕。当出现构建错误时，它们最终会出现在所有失败的测试之上。例如

Executed 0 out of 35 tests: 24 tests pass and 11 fail to build.
There were tests whose specified size is too big. Use the --test_verbose_timeout_warnings command line option to see which ones these are.

有没有办法隐藏所有“通过”测试目标，只输出构建和测试失败，以及底部的摘要行？我尝试过的记录在案的详细程度选项似乎都没有改变这一点。

不知道你试过什么。--test_output=errors --noshow_progress至少 0.12.0 对我来说效果很好。

bazel --batch test --jobs 2 --test_output=errors --noshow_progress --test_timeout=300,300,900,3600 //...
