junit - Play2 Java - InvalidPropertyException when testing controller with form -

-

i'd test controller method named authenticate(), has simple logic: validating email , password request , returning result json.

public class users extends controller {      static form<user> userform = form.form(user.class);      public static result login() {         return ok(views.html.users.login.render(userform));     }      public static result authenticate() {         form<user> filledform = userform.bindfromrequest();         if (filledform.haserrors()) {             return badrequest(views.html.users.login.render(filledform));         } else {             objectnode result = json.newobject();             user u = filledform.get();             if (user.isauthvalid(u.email, u.password))                 result.put("status", "ok");             else                 result.put("status", "authentication failed");             return ok(result);         }     } }

following test code authenticate():

@test public void callauthenticate() {     map<string, string> formdata = maps.newhashmap();     formdata.put("email", "aaa@bbb.com");     formdata.put("password", "password");      result result = callaction(controllers.routes.ref.users.authenticate(),             fakerequest().withformurlencodedbody(formdata));     assertthat(status(result)).isequalto(http.status.ok); }

but got error following stacktrace:

when testing on browser, worked expected. junit test fails invalidpropertyexception. what's wrong test code?

fyi, here's model user:

@entity public class user extends model {      @id     @required     @nonempty     public string email;      public string nickname;      @required     public string password;      public string salt;      public static finder<string, user> find = new finder<string, user>(             string.class, user.class);      public static user findbyemail(string email) {         return find.where().eq("email", email).findunique();     }      public static boolean isauthvalid(string email, string password) {         user user = findbyemail(email);         if (user == null)             return false;          return user.isvalidpassword(password);     }      public boolean isvalidpassword(string password) {         return this.password.equals(digestutils.md5hex(password + this.salt));     }  }

thanks advices/corrections.

you need run test inside "fake" application, binding can work. so, you're test this:

@test public void callauthenticate() {     running(fakeapplication(), new runnable() {         public void run() {             map<string, string> formdata = maps.newhashmap();             formdata.put("email", "aaa@bbb.com");             formdata.put("password", "password");              result result = callaction(controllers.routes.ref.users.authenticate(),             fakerequest().withformurlencodedbody(formdata));             assertthat(status(result)).isequalto(http.status.ok);         }     } }
