testing - Swift XCTest UI tests with Realm -


i'm developing ui test swift 3.0 using realm 2.4.2.

ui test target

  • create realm object cat pk "cat_01"
  • check if exists cat object pk "cat_01" -> success
  • open view controller contains list of cats fetched realm -> empty list

application

  • catslistviewcontroller: table view cats (no cat object found)

how can "see" both on test target , application same realm objects?

what not want using launcharguments workaround delegating app create objects.

you cannot "see" same realm objects in uitest target , application because 2 running separated processes.

from apple's docs:

ui testing exercises app's ui in same way users without access app's internal methods, functions, , variables. ... test code runs separate process, synthesizing events ui in app responds to.

in other words: uitests running in separate app interacts main app (when run uitest can see testrunner app being launched , closed before main app being launched). 2 apps can not share objects.

i see 2 directions go:

1. create cat objects via app's ui

somewhere have "add cat" button. press in uitest, add cat use , assert cat has been added list. uitests for. using app user , testing results of user's interaction app.

2. use unittests:

if want test created realm cat object populating list unittest might better way. during unittest have full access app's code. can create cat object in test code , app "see" it.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...

ios - Change Storyboard View using Seague -

i have following code checks connection server, , depending on want change views if no connection found. nsstring *connect = [nsstring stringwithcontentsofurl:[nsurl urlwithstring:@"http://myserver.com"] encoding:nsutf8stringencoding error:nil]; if (connect == null) { [self performseguewithidentifier:@"network_failure" sender:self]; } else { // other code here } my problem not change views. have added storyboard segue between 2 views identifier of network_failure . not have navigation controller or that, problem? thanks help! no not problem. first of all, in objectivec exists nil object oriented null . must use that. so: if(connect == nil) or better: if(!connect) so due fact nil not same of null , probably code does't enter in if scope . you have been able discover breakpoint. anyway: be sure set trigger segue (line) 2 view controller , , name network_failure (that not best name. should instead view1toview2 ) as, m...
