Testing net/http?
问题
我对如何构建Go Web应用程序及其测试有些困惑。我已经阅读了《如何编写Go代码》1，但仍然不太明白。例如，我有一个名为"beacon"的Go项目，在根目录下有一个beacon.go文件。添加一个简单的beacon_test.go文件（从http://golang.org/pkg/net/http/httptest/#example_Server中完全复制）会导致以下错误：
$ go test
# github.com/jelder/beacon
./beacon_test.go:11: main redeclared in this block
previous declaration at ./beacon.go:216
FAIL github.com/jelder/beacon [build failed]
确实，第11行是func main()。如果我将beacon_test.go中的package main改为package hello，则会出现以下错误：
can't load package: package github.com/jelder/beacon: found packages main (beacon.go) and hello (beacon_test.go) in /Users/jacob/src/github.com/jelder/beacon
英文:
I am a little confused about how to structure a go web app and its tests. I have read the How to Write Go Code but still don't get it. For example, I have a go project called "beacon" with a beacon.go file at the root. Adding a trivial beacon_test.go file (copied verbatim from http://golang.org/pkg/net/http/httptest/#example_Server) causes this error:
$ go test
# github.com/jelder/beacon
./beacon_test.go:11: main redeclared in this block
previous declaration at ./beacon.go:216
FAIL github.com/jelder/beacon [build failed]
Sure enough, line 11 is func main(). If I instead change the package main line in my beacon_test.go to package hello, I get this error instead:
can't load package: package github.com/jelder/beacon: found packages main (beacon.go) and hello (beacon_test.go) in /Users/jacob/src/github.com/jelder/beacon

得分: 1
beacon_test.go还有一个名为main()的函数，请将其重命名为TestFirst（或者任何其他以Test开头的名称，注意大写的T很重要）。这是没有必要的。只需从您正在工作的包内部（包含*.go文件的那个包）运行go test .即可。如果需要更多帮助，请发布完整的文件。
英文:
beacon_test.go has also a function called main() rename it to TestFirst (or any other name you like as long as it starts with Test, note the uppercase T is important). There is no need for that. Just run go test . from inside the package you are working on (the one containing the *.go files). Post the full files if you need more help.
