Go 未定义的功能-测试

我试图使用测试库对函数执行一组测试。我有两个脚本：

.
├── solve.go
└── solve_test.go

我希望对

Solve.go

中的

Solve

函数运行测试，因为它们都在同一个包中

当我执行测试时，控制台返回：

# command-line-arguments [command-line-arguments.test]
./solve_test.go:11:10: undefined: Solve
./solve_test.go:12:10: undefined: Solve
./solve_test.go:13:10: undefined: Solve
./solve_test.go:14:10: undefined: Solve
./solve_test.go:15:10: undefined: Solve
./solve_test.go:16:10: undefined: Solve
./solve_test.go:17:10: undefined: Solve
./solve_test.go:22:2: undefined: Solve

solve.go

package longest_vowel_chain

import "fmt"

func Solve(s string) int {
    for pos, char := range s {
        fmt.Println(char, pos)
    }

    return 0
}

package longest_vowel_chain

import (
    . "github.com/onsi/ginkgo"
    . "github.com/onsi/gomega"
    "testing"
)

func TestSolve(t *testing.T) {
    It("Basic tests", func() {
        Expect(Solve("codewarriors")).To(Equal(2))
        Expect(Solve("suoidea")).To(Equal(3))
        Expect(Solve("ultrarevolutionariees")).To(Equal(3))
        Expect(Solve("strengthlessnesses")).To(Equal(1))
        Expect(Solve("cuboideonavicuare")).To(Equal(2))
        Expect(Solve("chrononhotonthuooaos")).To(Equal(5))
        Expect(Solve("iiihoovaeaaaoougjyaw")).To(Equal(8))
    })
}

solve\u test.go

package longest_vowel_chain

import "fmt"

func Solve(s string) int {
    for pos, char := range s {
        fmt.Println(char, pos)
    }

    return 0
}

package longest_vowel_chain

import (
    . "github.com/onsi/ginkgo"
    . "github.com/onsi/gomega"
    "testing"
)

func TestSolve(t *testing.T) {
    It("Basic tests", func() {
        Expect(Solve("codewarriors")).To(Equal(2))
        Expect(Solve("suoidea")).To(Equal(3))
        Expect(Solve("ultrarevolutionariees")).To(Equal(3))
        Expect(Solve("strengthlessnesses")).To(Equal(1))
        Expect(Solve("cuboideonavicuare")).To(Equal(2))
        Expect(Solve("chrononhotonthuooaos")).To(Equal(5))
        Expect(Solve("iiihoovaeaaaoougjyaw")).To(Equal(8))
    })
}

我正在使用Go 1.12.5，我哪里出了问题？谢谢

您需要将源代码移动到

$GOPATH

中或使用。

您的文件是否放置在$GOPATH中？谢谢@demas如何检查此问题？

echo%GOPATH%

（在Windows命令提示符下）或LinuxOk上的

printenv | grep GOPATH

添加

Go Mod

修复了此问题。我认为你是对的，

GOPATH

设置不正确。
