如何安装 Azure terratest 模块

Question

我在安装 azure 模块时遇到以下错误。

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：

有人可以帮助我了解需要进行哪些更改才能消除此错误吗？

从 this initial state 开始：

-- 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 填写一组完整的（但可能不兼容）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

现在尝试 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
…

它会产生很多错误，这并非完全出乎意料：azure-sdk-for-go 在主要版本 55(!) 上，对我来说这表明中断更改率很高。所以这个版本的 terratest 可能是针对旧版本编写的，并且已被一些干预更改破坏。

要弄清楚 terratest 是针对哪个版本编写的，我可以检查 its go.mod file。在 terratest v0.36.5，它指定

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

让我们试试那个版本：

$ 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下载一个模块的特定版本，但我实际上需要一组包[=55] =] 来自该模块 - 我缺少这些包的某些依赖项的校验和。所以我会运行 go mod tidy 再次修复包图：

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

这就是诀窍：

$ go build . $
