Question

我是Golang的新手，通过编码练习，我将所有以下文件放在名为leap的目录中。我正在使用gvm来运行golang可执行文件（版本1.4），使用诸如“go test leap_test.go”之类的命令。

当我去测试leap_test.go 时，我得到以下结果：

# command-line-arguments
leap_test.go:5:2: open /home/user/go/leap/leap: no such file or directory
FAIL    command-line-arguments [setup failed]

如何包含IsLeap（）函数以使测试正确运行。
为什么甚至包括cases_test.go？似乎leap_test.go就是测试所需的全部内容。

cases_test.go

package leap

// Source: exercism/x-common
// Commit: 945d08e Merge pull request #50 from soniakeys/master

var testCases = []struct {
    year        int
    expected    bool
    description string
}{
    {1996, true, "leap year"},
    {1997, false, "non-leap year"},
    {1998, false, "non-leap even year"},
    {1900, false, "century"},
    {2400, true, "fourth century"},
    {2000, true, "Y2K"},
}

leap_test.go

package leap

import (
    "testing"
    "./leap"
)

var testCases = []struct {
    year        int
    expected    bool
    description string
}{
    {1996, true, "a vanilla leap year"},
    {1997, false, "a normal year"},
    {1900, false, "a century"},
    {2400, true, "an exceptional century"},
}

    func TestLeapYears(t *testing.T) {
        for _, test := range testCases {
            observed := IsLeap(test.year)
            if observed != test.expected {
                t.Fatalf("%v is %s", test.year, test.description)
            }
        }
    }

leap.go

package leap

import(
    "fmt"
)

func IsLeap(year int) bool {
  return true
}

Command go

Test packages

用法：

go test [-c] [-i] [build and test flags] [packages] [flags for test binary]

例如，

<强>飞跃/ leap.go

package leap

func IsLeap(year int) bool {
    return true
}

<强>飞跃/ leap_test.go

package leap

import (
    "testing"
)

var testCases = []struct {
    year        int
    expected    bool
    description string
}{
    {1996, true, "a vanilla leap year"},
    {1997, false, "a normal year"},
    {1900, false, "a century"},
    {2400, true, "an exceptional century"},
}

func TestLeapYears(t *testing.T) {
    for _, test := range testCases {
        observed := IsLeap(test.year)
        if observed != test.expected {
            t.Fatalf("%v is %s", test.year, test.description)
        }
    }
}

如果$GOPATH设置为包含leap包目录：

$ go test leap
--- FAIL: TestLeapYears (0.00s)
    leap_test.go:22: 1997 is a normal year
FAIL
FAIL    leap    0.003s
$

或者，如果您cd到leap包目录：

$ go test
--- FAIL: TestLeapYears (0.00s)
    leap_test.go:22: 1997 is a normal year
FAIL
exit status 1
FAIL    so/leap 0.003s
$

如何在本地创建和使用我自己的golang包来运行此测试？
