Go Test Command parameter issues

When using go test to unit test the Go code, encountered the issue of command parameters, Google, did not find a good explanation, in fact, is a few details.

The problem is that I want to enter some command-line arguments to run the program when I do the unit test.
Refer to the Go official documentation, just add-args and parameters to go test
For example

Go Test-args-classpath E:\testcase HelloWorld

That's the top.

-classpath E:\testcase HelloWorld

Is the parameter I entered, but this error:

Flag provided but not Defined:-classpath

It means that go test interprets-classpath as its own argument, rather than taking all the strings behind-args as a parameter of my program input.

There is no way, I had to in the program bar-classpath changed to Classpath, so the command line as follows

Go Test-args classpath E:\testcase HelloWorld

This barely solves the problem, but the reason for go test changed my source program.

In addition, when I want to print debug information, that is, to go test to increase the-V parameter, also encountered a small problem, I entered the

Go test-v-args classpath E:\testcase HelloWorld

In the source code this, I pass the os. Args goes to get command-line arguments, but-V is treated as an input to my command line, not ignored. In principle, it should be-args to be treated as a command-line argument, and the go test does not actually do this. So I can only modify the source program to complete the test.

In the go test process, the use of command line parameters is relatively small, but I have encountered, and there are some unexpected problems, the go test is not perfect. In addition, I was just beginning to touch the go language, perhaps there is a better way or understand the wrong, here just to make a note for yourself, please forgive me.
