Bazel: More verbose test failure output

[mikedanese]

Is there a way to get more verbose test output?

When I run bazel test

➜  libkubernetes git:(master)# bazel test //test                              
INFO: Found 1 test target...
FAIL: //test:test (see /home/miked/.cache/bazel/_bazel_miked/f4f1511ac3aadf22b22f6857b29e43da/libkubernetes/bazel-out/local_linux-fastbuild/testlogs/test/test/test.log).
Target //test:test up-to-date:
  bazel-bin/test/test
INFO: Elapsed time: 0.235s, Critical Path: 0.01s
//test:test                                                              FAILED

Executed 1 out of 1 tests: 1 fails locally.

This output is not very useful to me. When I run the test binary directly I get more useful test output:

➜  libkubernetes git:(master)# ./bazel-out/local_linux-fastbuild/bin/test/test
[==========] Running 1 test from 1 test case.

[  FAILED  ] MyTest.thing (0 ms)

 1 FAILED TEST

For reference, I am testing in this repo https://github.com/mikedanese/libkubernetes

Have you tried --test_output=errors? (Same result as cat-ing the test log
file whose location is printed using the default settings.)

Awesome! Exactly what I was looking for. Thanks!

Adding this to the docs/tutorial somewhere would be fantastic.

[apelisse]

is there a way to make this the default (config, env)?

[mikedanese]

@apelisse in your .bazelrc you can add

test --test_output=errors

e.g. here: https://github.com/kubernetes/kubernetes/blob/master/.bazelrc#L3

Any way to get colors on the output?

[datoga]

I answer my self:

bazel test --test_output=errors --action_env="GTEST_COLOR=1" ...
