bazel-测试运行时的可写归档路径 [英] bazel - writable archivable path for test runtime

问题描述

我正在使用一些bazel测试目标(java_test的scala风格)进行E2E测试.

I'm running E2E test using some bazel test target (the scala flavour of java_test).

在Maven中，我曾经将日志转储到在测试期间创建的target/logs文件夹中，然后如果出现故障-我本可以在此文件夹中查找日志.

In Maven I used to dump logs to target/logs folder that was created during test time, and then if something failed - I could have looked in this folder and find the logs.

在bazel中-我可以在测试日志配置中输入什么路径，以便在测试完成/测试失败时可写且方便使用?

In bazel - what path can I put in my test logs configuration so it would be writable and conveniently available upon test finish / test failure?

我知道java.io.tmp目录是可写的，但是在测试完成后会立即被删除.

I know that the java.io.tmp dir is writable but gets deleted immediately after test finishes.

推荐答案

因此，通过浏览Bazel文档，我发现了这一点: https://docs.bazel.build/versions/master/test -encyclopedia.html#initial-conditions

So digging through bazel docs I found this: https://docs.bazel.build/versions/master/test-encyclopedia.html#initial-conditions

似乎我可以读取env变量"TEST_UNDECLARED_OUTPUTS_DIR"，它将给我一条可写的路径.我写的所有内容都将被压缩并保存在./bazel-out/darwin-fastbuild/testlogs/<package-name>/<target-name>/test.outputs/outputs.zip

Seems like I can read env variable "TEST_UNDECLARED_OUTPUTS_DIR" and it will give me a writable path. Anything I write there would be zipped and saved under ./bazel-out/darwin-fastbuild/testlogs/<package-name>/<target-name>/test.outputs/outputs.zip

很酷！
