java - Junit test case for a restful client using mockito -

-

i have no idea before how write test cases, when saw online tutorials understand how write simple method success , failure scenario. have method http calls restful api , returns json response. have 6 parameters include in url , json response back. now, understanding far success scenario here should hard code input parameters , test if getting json , failure not getting json response back. correct or have else?

i mean have code like

public list getstorelocations(storedata storedata) {   list storelist = null;    try {     httpclient httpclient = httpclientbuilder.create().build();     stringbuilder urlstrngbuildr = new stringbuilder(             https://<hostname>/xyz/abc);     utility.addparametertourl(urlstrngbuildr,             utility.app_name,             constants.app_value);     utility.addparametertourl(urlstrngbuildr,             constants.version_param_name,             constants.version_param_value);     if (storedata.getcity() != null && storedata.getstate() != null) {         stringbuilder addressparamvalue = new stringbuilder(                 storedata.getcity());         addressparamvalue.append(constants.comma);         addressparamvalue.append(storedata.getstate());         utility.addparametertourl(urlstrngbuildr,                 constants.address_param_name,                 addressparamvalue.tostring());     } else if (storedata.getzip() != null) {         utility.addparametertourl(urlstrngbuildr,                 constants.zip_param_name, storedata.getzip());     }      utility.addparametertourl(urlstrngbuildr,             constants.product_param_name,             storedata.getproduct());     utility.addparametertourl(urlstrngbuildr,             constants.country_param_name,             storedata.getcountry());     utility.addparametertourl(urlstrngbuildr,             constants.distance_param_name,             storedata.getdistance());     utility.addparametertourl(urlstrngbuildr,             constants.size_param_name, storedata.getsize());      httpget getrequest = new httpget(new java.net.uri(             urlstrngbuildr.tostring()));      getrequest.addheader(basicscheme.authenticate(             new usernamepasswordcredentials(username,password),         constants.encoding_type, false));      jsonresponsehandler responsehandler = new jsonresponsehandler();     string json = httpclient.execute(getrequest, responsehandler)             .tostring();      gson gson = new gson();      storeresponse response = gson.fromjson(json,             storeresponse.class);      storedetails[] strdetails = response.getresult();      storedetailslist = arrays.aslist(strdetails);    } catch (exception exeption) {     exeption.printstacktrace();   }    return storelist;  }

maybe should take @ rest-assured, rest api testing framework.

the nice thing is, easier read, supports json , xml , allows test things http-codes or specific values response.

get("/lotto")    .then()       .assertthat().body("lotto.lottoid", equalto(5));

you add parameters param method:

given()     .param("key1", "value1")     .param("key2", "value2") when().    aso...

if need authentication, in code, can use following:

given()   .auth()      .basic(username,password)   .when()      .get("/secured")   .then()      .statuscode(200);`

hope helps testing.

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
