go - Bazel Golang 综合覆盖率报告

Question

我正在尝试使用

bazel coverage --combined_report=lcov  //...

但它总是失败并显示相同的消息:

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

自然我用了flag --test_verbose_timeout_warnings我得到了错误

//pkg/util:go_default_test                                      (cached) PASSED in 4.4s
WARNING: //pkg/util:go_default_test: Test execution time (4.4s excluding execution overhead) outside of range for MODERATE tests. Consider setting timeout="short" or size="small".

然后我用 --nocache_test_results 试了一下但没什么不同。

我试过了

bazel coverage --combined_report=lcov --test_size_filters=small //...

这就是我得到的:

WARNING: All specified test targets were excluded by filters
INFO: Build option --instrumentation_filter has changed, discarding analysis cache.
INFO: Analyzed 52 targets (0 packages loaded, 8254 targets configured).

使用 bazel coverage --combined_report=lcov --test_size_filters=small,medium --nocache_test_results //...结果在这

Executed 11 out of 11 tests: 11 tests pass.
There were tests whose specified size is too big. Use the --test_verbose_timeout_warnings command line option to see which ones these are.
All tests passed but there were other errors during the build.

我似乎无法获得综合覆盖率报告。

您可能使用的是旧版本的 bazel。尝试使用 2.1.0 或更高版本。
