如何安装Azure terratest模块

Question

在安装azure模块时，我得到了以下错误。

代码：

package test

import (
    "testing"
    "github.com/Azure/azure-sdk-for-go/profiles/latest/cosmos-db/mgmt/documentdb"
    "github.com/gruntwork-io/terratest/modules/azure"
    "github.com/stretchr/testify/assert"
)

func TestTerraformAzureCosmosDBExample(t *testing.T) {
    foo
    boo
}

执行：

C:\foo\boo>go test -v
# foo_test
foo_test.go:6:2: no required module provides package github.com/gruntwork-io/terratest/modules/azure; to add it:
        go get github.com/gruntwork-io/terratest/modules/azure
FAIL    foo_test [setup failed]

错误：

有人能帮我解决这个错误所需的更改吗？

从这个初始状态出发

-- main.go --
package main

import (
    _ "github.com/Azure/azure-sdk-for-go/profiles/latest/cosmos-db/mgmt/documentdb"
    _ "github.com/gruntwork-io/terratest/modules/azure"
    _ "github.com/stretchr/testify/assert"
)

func main() {}
-- go.mod --
module example.com/m

go 1.17

首先，运行go mod tidy来填充一组完整(但可能不兼容)的依赖项。

$ go mod tidy
go: finding module for package github.com/stretchr/testify/assert
go: finding module for package github.com/Azure/azure-sdk-for-go/profiles/latest/cosmos-db/mgmt/documentdb
go: finding module for package github.com/gruntwork-io/terratest/modules/azure
go: found github.com/Azure/azure-sdk-for-go/profiles/latest/cosmos-db/mgmt/documentdb in github.com/Azure/azure-sdk-for-go v55.6.0+incompatible
go: found github.com/gruntwork-io/terratest/modules/azure in github.com/gruntwork-io/terratest v0.36.5
go: found github.com/stretchr/testify/assert in github.com/stretchr/testify v1.7.0
go: finding module for package github.com/gofrs/uuid
go: found github.com/gofrs/uuid in github.com/gofrs/uuid v4.0.0+incompatible

现在试试go build。

$ go build .
# github.com/Azure/azure-sdk-for-go/services/mysql/mgmt/2020-01-01/mysql
.gopath/pkg/mod/github.com/!azure/azure-sdk-for-go@v55.6.0+incompatible/services/mysql/mgmt/2020-01-01/mysql/models.go:346:2: undefined: azure.FutureAPI
…

它会产生许多错误，这并不是完全出乎意料的：azure-sdk-for-go在55(!)版上，对我来说，这表明了很高的变化率。因此，这个版本的terratest很可能是针对旧版本编写的，并且已经被一些中间的更改破坏了。

为了弄清楚terratest是针对哪个版本编写的，我可以检查文件。在terratest v0.36.5，它指定

    github.com/Azure/azure-sdk-for-go v46.0.0+incompatible

所以让我们试试这个版本：

$ go get -d github.com/Azure/azure-sdk-for-go@v46.0.0+incompatible
go: downloading github.com/Azure/azure-sdk-for-go v46.0.0+incompatible
go get: downgraded github.com/Azure/azure-sdk-for-go v55.6.0+incompatible => v46.0.0+incompatible

现在再来一次go build：

$ go build .
.gopath/pkg/mod/github.com/!azure/azure-sdk-for-go@v46.0.0+incompatible/services/mysql/mgmt/2020-01-01/mysql/models.go:28:2: missing go.sum entry for module providing package github.com/satori/go.uuid (imported by github.com/Azure/azure-sdk-for-go/services/keyvault/mgmt/2016-10-01/keyvault); to add:
        go get github.com/Azure/azure-sdk-for-go/services/keyvault/mgmt/2016-10-01/keyvault@v46.0.0+incompatible

这是因为我告诉go get下载一个特定版本的模块，但实际上我需要从该模块中下载一组包-而且我缺少这些包的一些依赖项的校验和。因此，我将运行go mod tidy来重新修复包图：

$ go mod tidy
go: downloading github.com/satori/go.uuid v1.2.0

这就是诀窍：

$ go build .
