如何使用go test -run运行特定的golang测试

Question

What am I doing wrong here? I just want to run this one ConnectionPoolTest.TestNew and what ever I try, I get back 'no test to run'

:go test  --check.list *.go |grep Connectio
ConnectionPoolTest.TestNew
:go test  --run ConnectionPoolTest *.go
ok      command-line-arguments  0.005s [no tests to run]
:go test  --run ConnectionPoolTest.TestNew *.go
ok      command-line-arguments  0.005s [no tests to run]

If you want to run a specific test, you may run as bellow

package main

import (
    "testing"
    "github.com/stretchr/testify/assert"
)

func TestA(t *testing.T) {
    assert.True(t, true)
}

func TestB(t *testing.T) {
    assert.True(t, false)
}

Run Test:

$ go test -run B
--- FAIL: TestB (0.00s)
        Error Trace:    a_test.go:13
        Error:          Should be true
FAIL
exit status 1
FAIL    test    0.004s
$ go test -run A
PASS
ok      test    0.003s

-run flag

-run regexp
        Run only those tests and examples matching the regular expression.
        For tests the regular expression is split into smaller ones by
        top-level '/', where each must match the corresponding part of a
        test's identifier.
