Issue in testing web app

When I am writing my test case, I am using a views_test.go file in the views package, yet, the test cases says "function not found", the function is a part of this package and it is unable to find it, when I try importing the views package unto itself (I know this is a cycling import, only then it works) it works file if I run go test views/views_test.go but fails at go test ./views/

    func TestWrongMethodSearchHandler(t *testing.T) {
            token :=   "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6InN1cmFqIiwiZXhwIjoxNDg4NzA0MTg5fQ.eZKNxaOBJv0oRyFKZR5vF8u3xqKDvuGB_KAWsB2ElBI"

    ts := httptest.NewServer(http.HandlerFunc(SearchHandler))
    defer ts.Close()

    testCases := []struct {
            method     string
            wantStatus int
    }{
            {
                    "GET",
                    http.StatusOK,
            },
    }

    for _, tc := range testCases {

            req, err := http.NewRequest(tc.method, ts.URL, nil)
            req.Form = make(map[string][]string, 0)
            req.Form.Add("name", "business")
            if err != nil {
                    t.Fatal(err)
            }
            req.Header.Set("token", token)

            rr := httptest.NewRecorder()
            SearchHandler(rr, req)

            if status := rr.Code; status != tc.wantStatus {
                    t.Errorf("handler returned wrong status code: got %v want %v", status, http.StatusOK)

            }
    }
}

It would be better if you post the code. But the only thing that I can think of right now is that you've given a different package name in the test file. Like both files are in the same folder, but instead of both having package name views, the test file has package name views_test, and then from this package you can't access the unexported functions of the views package.

That's what is strange, both files normal and test case have the same package name "views". Still it throws that error! I have updated the question to contain the handler test case.
After I get this to work, it says table not found for each SQL query, I am going nuts on this issue, can't seem to solve it.

neopointer:

That should be easy to track. It seems you are not connecting to the right database then...

thewhitetulip:

Now this is where I don't understand where things are headed! I am writing an app using sqlite3, I don't know which db the server is referring to!

thewhitetulip:

Can you show me an example unit test case about a web server? I didn't find a single document on the web which teaches how to test a webserver, I am writing a RESTful API.

neopointer:

Honestly I don't have much experience with testing in go. So I would suggest that you check how you are constructing your db connection to know where are you connecting to. It could be that are using an in-memory database connection with sqlite, so it will always be empty.

thewhitetulip:

I found out now that I am testing from inside the views directory, this it created a new sqlite database in my filepath, testing with that code now! I am still stumped as to why I have to import views inside the views package, it is strange.

thewhitetulip:

    views $  go test
    2017/03/05 13:08:18 map[name:[business]]
    2017/03/05 13:08:18 business
    2017/03/05 13:08:18 searching for product name  business
    2017/03/05 13:08:18 map[name:[business]]
    PASS
    ok      github.com/thewhitetulip/views  0.068s
    views $  go test views_test.go
    # command-line-arguments
    ./views_test.go:12: undefined: SearchHandler
    ./views_test.go:36: undefined: SearchHandler
    ./views_test.go:47: undefined: SearchHandler
    ./views_test.go:59: undefined: SearchHandler
    FAIL    command-line-arguments [build failed]
    ```

Okay, so I figured out the issue, I wasn't doing testing properly, I did go test views_test.go instead of go test, by doing go test it works fine!!

neopointer:

You can also use go test ./... from the root folder (it will test everything). Happy coding :)

Thank you for your help!!

Shameless self promotion:
Take a look at github.com/tmornini/http-spec
I wrote it to test APIs via HTTP.
It's fast, written in go, and is being actively used and developed.

thewhitetulip:

Thanks! For what it's worth, I don't see this as shameless self promotion, if not for self promotion how are you going to spread word about what you built? :-)
Sure some might detest this, but let's not get swayed by a few such folks, let's do good work and spread the word about it!
