英文:
Toggle Test Coverage with os.Getenv
问题
我正在进行一个简单的测试，并在Visual Studio Code中使用Go: Toggle Test Coverage In Current Package进行测试，就像这样<br>
在我的代码中，我使用os.Getenv从我的环境中读取一个变量。<br>
使用os.Getenv时，它返回FAIL，但是硬编码时返回SUCCESS<br>
<br>
如何在使用Go: Toggle Test Coverage In Current Package时，即使从env中获取数据，也能获得SUCCESS？
这是我的代码：
type MyStruct struct {Name string `json:"name"`}func MyFunc() ([]MyStruct, error) {str := os.Getenv("MyStruct") // 失败// str := `[{\"name\": \"one\"}, {\"name\": \"two\"}]` // 成功var myData []MyStructerr := json.Unmarshal([]byte(str), &myData)if err != nil {return nil, err}return myData, nil}
我的测试代码：
func TestMyFunc(t *testing.T) {tests := []struct {name stringwant []MyStructwantErr error}{{name: "success",want: []MyStruct{{Name: "one",},{Name: "two",},},wantErr: nil,},}for _, tt := range tests {t.Run(tt.name, func(t *testing.T) {got, err := MyFunc()assert.Equal(t, err, tt.wantErr)assert.Equal(t, got, tt.want)})}}
我的环境：
export MyStruct='[{\"name\": \"one\"}, {\"name\": \"two\"}]'
使用

I'm making a simple test, and test using Go: Toggle Test Coverage In Current Package in Visual Studio Code like this<br>
In my code is using os.Getenv to read a variable from my own env.<br>
It get FAIL when using os.Getenv, but SUCCESS when hardcoded<br>
<br>
How to get SUCCESS even get data from env using Go: Toggle Test Coverage In Current Package?
Here is my code:
type MyStruct struct {Name string `json:"name"`}func MyFunc() ([]MyStruct, error) {str := os.Getenv("MyStruct") // Fail// str := `[{"name": "one"}, {"name": "two"}]` // Successvar myData []MyStructerr := json.Unmarshal([]byte(str), &myData)if err != nil {return nil, err}return myData, nil}
My test code:
func TestMyFunc(t *testing.T) {tests := []struct {name stringwant []MyStructwantErr error}{{name: "success",want: []MyStruct{{Name: "one",},{Name: "two",},},wantErr: nil,},}for _, tt := range tests {t.Run(tt.name, func(t *testing.T) {got, err := MyFunc()assert.Equal(t, err, tt.wantErr)assert.Equal(t, got, tt.want)})}}
My env:
export MyStruct='[{"name": "one"}, {"name": "two"}]'
Using

我找到了解决方案<br>
只需将以下代码添加到测试代码中：
strEnv := `[{"name": "one"}, {"name": "two"}]`err := os.Setenv("MyStruct", strEnv)if err != nil {return}
英文:
I found the solution<br>
Just add this code to test code:
strEnv := `[{"name": "one"}, {"name": "two"}]`err := os.Setenv("MyStruct", strEnv)if err != nil {return}
