`go test`失败了，因为它无法读取root dir中的文件

初始化中读取config.xml

软件包模型是导入package config，在运行测试时的 ;我遇到一个错误，抱怨它无法读取文件。

我已经检查了该文件是否存在，并且可以运行我的应用程序（读取配置文件）

Golang测试是否在rootdir中运行吗？有没有办法在没有太多重构的情况下进行此测试？

server git:(main) ➜ go test -v ./model/...
2022/07/06 15:46:21 config.go:72: Reading config file config.yaml
2022/07/06 15:46:21 config.go:75: open config.yaml: no such file or directory

原文

package model is imports package config which reads config.xml in it's init

When running test; I get an error complaining it cannot read the file.

I've checked the file does exists and I can run my application(read the config file)

Does golang test not run in rootdir ? Is there a way I can run this test without too much refactoring?

server git:(main) ➜ go test -v ./model/...

假设以下文件结构：

workspaces
└── gotests
    └── main.go
        packages
        └── read
            └── file_test.go
        testfile
        └── test.txt

file_test.go内容：

package read_test

import (
    "fmt"
    "os"
    "testing"
)

func TestReadFile(t *testing.T) {
    t.Run("I read a file", func(t *testing.T) {
        currentDir, err := os.Getwd()
        if err != nil {
            panic(err)
        }

        executable, err := os.Executable()
        if err != nil {
            panic(err)
        }

        fmt.Printf("Current dir: %v\n", currentDir)
        fmt.Printf("Executable: %v\n", executable)

        bytes, err := os.ReadFile("../../testfile/test.txt")
        if err != nil {
            panic(err)
        }

        fmt.Println(string(bytes))
    })
}

如果您运行GO test ./packages/read -run = testReadFile -count -count = 1 -V在同一文件夹中main.go（在我的情况下，/workspaces/gotests），您可以期待以下日志：

=== RUN   TestReadFile
=== RUN   TestReadFile/I_read_a_file
Current dir: /workspaces/gotests/packages/read
Executable: /tmp/go-build1080340781/b001/read.test
Im some test text.
--- PASS: TestReadFile (0.00s)
    --- PASS: TestReadFile/I_read_a_file (0.00s)
PASS

Assume the following file structure:

workspaces
└── gotests
    └── main.go
        packages
        └── read
            └── file_test.go
        testfile
        └── test.txt

file_test.go contents:

package read_test

import (
    "fmt"
    "os"
    "testing"
)

func TestReadFile(t *testing.T) {
    t.Run("I read a file", func(t *testing.T) {
        currentDir, err := os.Getwd()
        if err != nil {
            panic(err)
        }

        executable, err := os.Executable()
        if err != nil {
            panic(err)
        }

        fmt.Printf("Current dir: %v\n", currentDir)
        fmt.Printf("Executable: %v\n", executable)

        bytes, err := os.ReadFile("../../testfile/test.txt")
        if err != nil {
            panic(err)
        }

        fmt.Println(string(bytes))
    })
}

If you run go test ./packages/read -run=TestReadFile -count=1 -v in the same folder as main.go (in my case, /workspaces/gotests), you can expect a log like:

=== RUN   TestReadFile
=== RUN   TestReadFile/I_read_a_file
Current dir: /workspaces/gotests/packages/read
Executable: /tmp/go-build1080340781/b001/read.test
Im some test text.
--- PASS: TestReadFile (0.00s)
    --- PASS: TestReadFile/I_read_a_file (0.00s)
PASS
