## Go-Learning
go 语言学习尝试
### 基础概念
1. GOROOT：Go 语言安装根目录的路径，也就是 GO 语言的安装路径。
2. GOPATH：若干工作区目录的路径。是我们自己定义的工作空间。
3. GOBIN：GO 程序生成的可执行文件（executable file）的路径。
**设置 GOPATH 的意义是什么？**
### go get 安装包失败怎么办
错误信息的表现
```shell script
go get github.com/stretchr/testify: module github.com/stretchr/testify: Get "https://proxy.golang.org/github.com/stretchr/testify/@v/list": dial tcp 216.58.200.241:443: connectex: A
connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
```
使用国内的安装 [proxy](https://github.com/goproxy/goproxy.cn)
#### 使用方法
限制条件: Go 1.13 and above (RECOMMENDED)
```shell script
go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.cn,direct
```
### go 测试框架
go 测试框架目前看 [testify](https://github.com/stretchr/testify) 是主流框架
```go
package yours
import (
"testing"
"github.com/stretchr/testify/assert"
)
func TestSomething(t *testing.T) {
// assert equality
assert.Equal(t, 123, 123, "they should be equal")
// assert inequality
assert.NotEqual(t, 123, 456, "they should not be equal")
// assert for nil (good for errors)
assert.Nil(t, object)
// assert for not nil (good when you expect something)
if assert.NotNil(t, object) {
// now we know that object isn't nil, we are safe to make
// further assertions without causing any errors
assert.Equal(t, "Something", object.Value)
}
}
```
### Introduce local variable in Gogland ide
[原答案地址](https://stackoverflow.com/questions/44657806/introduce-local-variable-in-gogland-ide)
You need to use CTRL+ALT+V for Windows / Linux (or CMD+ALT+V on OS X) or invoke the Refactor | Extract | Variable and then select the function call from the list and the variables will be inserted for you.
