No nonsense, a simplified httptest library

This is a creation in Article, where the information may have evolved or changed.

Do not mention the library, to a net/http/httptest library to write general handler test method (source):

Package Handlersimport ("Net/http" "Net/http/httptest" "testing") Func Testhealthcheckhandler (t *testing. T) {//Create a request to pass to our handler.    We don ' t have any query parameters for now, so we'll//pass ' nil ' as the third parameter. Req, Err: = http. Newrequest ("GET", "/health-check", nil) if err! = Nil {t.fatal (ERR)}//We Create a Responserecorder (wh Ich satisfies http.    Responsewriter) to record the response. RR: = Httptest. Newrecorder () Handler: = http. Handlerfunc (Healthcheckhandler)//Our handlers satisfy HTTP.    Handler, so we can call their Servehttp method//directly and pass with our Request and Responserecorder. Handler.    Servehttp (RR, req)//Check The status code is what we expect. If status: = RR. Code; Status! = http. Statusok {T.errorf ("handler returned wrong status Code:got%v want%v", status, HTTP.    Statusok)}//Check The response body is what we expect. Expected: = ' {' Alive ': True} ' if RR. Body.string ()! = expected {T.errorf ("handler returned unexpected Body:got%v want%v", RR. Body.string (), expected)}}

It is simple to test a method with at least as many lines of code as a simple get request, and as for whether the request is to add parameters or not, it becomes another bigger problem.

Usage of the Library

A test that returns 400 forever Handlerfunc Badhandler (w http. Responsewriter, R *http. Request) {http. Error (W, "not a regular name or password", http. Statusbadrequest)}//Tests whether this handler returns 400NEW ("/bad", Badhandler, T). Do (). Checkcode (http. statusbadrequest)//test He is not returning 200 (of course will test failed) New ("/ok", Badhandler, T). Do (). Checkcode (http. Statusok)//With the header test new ("/", Badhandler, T). Post (). Addparams ("name", "Value1"). Addparams ("Nam22", "Value3"). Do ()//Take a cookie test and determine if the result contains a string. New ("/", Cookiehandler, T). Get (). Addcookies (Cookie). Do (). Bodycontains ("Testcookievalue")//Get *http. Responserecorder, and then test your own RR = New ("/dump", HeaderHandler, T). Post (). Addparams ("name", "Value1"). Do (). Responserecorder ()//Add parameter to request, do not write default is GET request new ("/ok", Badhandler, T). Addparams ("A", "AA"). Addparams ("b", "BB"). Do (). Checkcode (http. Statusok)//http Basic auth:new ("/bad", Badhandler, T). Setbasicauth (username, password). Do (). Checkcode (http. Statusbadrequest)//Custom HTTP. Request:new ("/bad", Badhandler, T). Setrequest (req). Do (). Checkcode (http. Statusbadrequest)//and mOre in test file and source code. 

Must have to be .Do() able to make the request, otherwise it will not be requested.
The check operation is to be preceded by the .Do() initialization operation .Do() .
