Alternatives to mock an static method
java,junit,static,mocking,mockito
While putting a null pointer check in the static method would avoid the NPE being thrown; it it a bit of a code smell. I would suggest that the jTextArea be declared as non-static which in turns implies that the printInMain method would also be non-static. This then leads to...
How to mock a redis client in Python?

Python mock access “real” objects while mocking a module
This is happening because your mock is actually overwriting the entire requests module in your code. Here is how you can debug this: In your code, add this: try: requests.post('', data='') except (requests.ConnectionError, requests.Timeout): was_successful = False except Exception, err: import pdb pdb.set_trace() When you run the test, you will...
How to stub CocoaLumberjack or NSLog with OCMockito
ios,objective-c,unit-testing,mocking,ocmockito
All standard DDLog macros call +[DDLog log:level:flag:context:file:function:line:tag:format:], so with OCMock, you would verify the DDLogInfo was called by: - (void)testMethodCallsDDLogInfo { id mockDDLog = OCMClassMock([DDLog class]); [obj methodThatCallsDDLogInfo]; OCMVerify([mockDDLog log:YES level:DDLogLevelAll flag:DDLogFlagInfo context:0 file:[OCMArg anyPointer] function:[OCMArg anyPointer] line:58 tag:[OCMArg any] format:[OCMArg any]]); } Unfortunately, with this strategy you must hard-code...
Is there a way to tell Autofixture to only set properties with a specific attribute?
c#,unit-testing,dependency-injection,mocking,autofixture
This works: public class PropertyBuilder : ISpecimenBuilder { public object Create(object request, ISpecimenContext context) { var pi = request as PropertyInfo; if (pi != null) { if (pi.IsDefined(typeof (DependencyAttribute))) return context.Resolve(pi.PropertyType); //"hey, don't set this property" return new OmitSpecimen(); } //"i don't know how to handle this request - go...

How to call mocked method in Python mock
python,unit-testing,mocking,python-mock
The simplest way is to grab your own reference to the original function before patching. Patching can be done on an individual instance of the class: original_foo = f.foo with patch.object(f, 'foo') as mock_foo: def side_effect(a): print "mock foo", a return original_foo(a*2) mock_foo.side_effect = side_effect f.foo(2) ...or by patching the...
can't inject Providers mock in JerseyTest
java,mocking,jersey,integration-testing,inject
Providers shouldn't have to be mocked. It is handled by the framework. Any providers you want added, just register with the ResourceConfig. I don't know what you care doing wrong in your attempt at this, but below is a complete working example where the ContextResolver is discovered just fine. If...
Stubbing a method in php
If $params->redirect('/signin'); is the line it breaks i think you should be able to solve this with. In the setup: $this->app = $this->getMock( '\Slim\Slim', array('redirect'), array(array('mode' => 'testing')) ); array(array( is on purpose as it is an array of constructor arguments and your constuctor looks like it wants an array...
Unable to mock __subclasses__ in python
__subclasses__ is not part of the class spec. It is part of the metatype of the class (type here). Python always looks up special methods on the type, never directly. If and when Python needs to call __subclasses__, it'll not do so directly, it'll use type(classobj).__subclasses__(classobj) to look up the...
Moq SignalR Client events
You need to design your code so that you only have dependecy to the IHubProxy interface You can look at my .NET client library to see how it can be solved https://github.com/AndersMalmgren/SignalR.EventAggregatorProxy/tree/master/SignalR.EventAggregatorProxy.Client.DotNet In my case some of the code needed the actual concrete HubProxy so what I did was to...
random.choice gives different results on Python 2 and 3
According to https://docs.python.org/2/library/random.html, the RNG was changed in Python 2.4 and may use operating system resources. Based on this and the other answer to this question, it's not reasonable to expect Random to give the same result on two different versions of Python, two different operating systems, or even two...
ActiveRecord: Mock has_many relation call
ruby-on-rails,activerecord,rspec,mocking
The reason this isn't working, is that the delete action loads its own version of car - it isn't using the local variable you have declared locally to your spec. So any stubs you add to your local variable will not actually exist on the brand new copy of car...
