如何在本地创建和使用我自己的golang软件包来运行此测试？

问题描述：

I'm new to golang working through coding exercises and I have all the following files in a directory called leap. I'm using gvm to run the golang executable (version 1.4), using a command such as "go test leap_test.go".

When I do go test leap_test.go I get the following results:

# 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]

How do I include the IsLeap() function so that the tests run correctly.
Why is cases_test.go even included? It seems like leap_test.go is all you'd need for tests.

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
}

我是golang编码练习的新手，我将以下所有文件放在一个名为jump的目录中。我正在使用gvm来运行golang可执行文件（1.4版），并使用“ go test jump_test.go”之类的命令。 p>

当我执行 go测试jump_test.go em>时，我得到以下结果： p>

 ＃命令行 -arguments 
leap_test.go：5：2：打开/ home / user / go / leap / leap：无此类文件或目录

如何包括IsLeap（）函数，以便测试能够正确运行。 li> 
 
为什么还要包含case_test.go？ 似乎所需的测试就是jump_test.go。 li>

答

Command go

Test packages

Usage:

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

For example,

leap/leap.go

package leap

func IsLeap(year int) bool {
    return true
}

leap/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)
        }
    }
}

If $GOPATH is set to include the leap package directory:

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

Or, if you cd to the leap package directory:

$ 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软件包来运行此测试？
