bazel cc_test test_env选项

Question

当我使用cc_test时，比如：

cc_test(
    name = "xxx_test",
    srcs = glob([
        'xxx.cpp',
    ]),
    linkopts = [
        "-L/usr/local/lib",
        "-lcppunit",
        "-ldl",
        "-lz",
        "-ltbb",
        "-llz4",
        "-lzstd"
    ],
    deps = [
        ":feature_generator"
    ],
)

我需要运行这个cmd：

./bazel test @xxx//xxx:xxx_test --test_output=errors --test_env=LD_LIBRARY_PATH=/usr/local/lib

我怎么能省略它"--test_env=LD_LIBRARY_PATH=/usr/local/lib".

cc_test有env_path选项吗？

我想这样做

cc_test( 
*** 
*** 
test_env = ['/usr/local/lib'] 
) 

我可以在这个cmd:./bazel test @xxx//xxx:xxx_test --test_output=errors中进行测试，当我想要测试时，我不想写"--test_env=LD_LIBRARY_PATH=/usr/local/lib"

现在，如果我运行这个cmd:./bazel test @xxx//xxx:xxx_test --test_output=errors会得到这个错误：

因此您可以将该标志添加到您的~/..bazelrc文件中，例如：

test --test_env=LD_LIBRARY_PATH=/usr/local/lib

但是，在我看来，测试操作无法找到LD_LIBRARY_PATH，而构建操作听起来像是一个bug，您应该在https://github.com/bazelbuild/bazel/issues/new上提交一个问题。
