在使用go test时，无论成功与否，如何在golang中不使用冗长模式的情况下始终打印一条消息？

Question

Is there any way to print a message when using go test regardless of success or failure without using verbose mode?

I'm generating dummy data and repeatedly running the test and would like to always tell developers the cases covered by the test.

Looking around all the questions I see about this just point to verbose mode and I don't see anything in the godoc.

Answer 1

You can't in all cases.

Tests are compiled and executed by the go test process. The stdout and stderr are captured by the parent process, and only displayed in verbose mode.

The exceptions are documented in the test code:

// stream test output (no buffering) when no package has
// been given on the command line (implicit current directory)
// or when benchmarking.

So if you are in the package directory, or running benchmarks, the stdout and stderr will be streamed through the parent process.
