How to unit test Java Hbase API

Edit 'Unit Test' is to verify, and validate a particular 'unit of code'. If that 'unit of code' depends on external calls, then we mock those calls to return certain values. If you don't invoke the 'actual unit of code' from your test case, then what is the point in...

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...
Junit VerificationModeFactory.times() vs mockito.times()
I thought it would be faster to ask rather than go check by myself :) I was lazy and wrong so I did the check by myself and here is the answer. It is the same thing, Mockito.Times() is internally calling the VerificationModeFactory.times() From Mockito.class /** * Allows verifying exact...
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...
Mocked repository does not trigger as expected
spring,unit-testing,mocking,mockito,mockmvc
1.) Why does the mock not trigger? I suppose it does not check for value equality in the object, but for object identifiers, which are not the same... By default, Mockito delegates to your object's equals method. If you haven't overridden that, then it checks references by default. The...
Mockito: How to test if another class' method is called within a method of a Mock?
junit,mocking,mockito,jboss-arquillian,verify
This can be done via multiple ways but I will go over one. First, because you use @Inject to get your instance of OrganisationService, then I will not mess around with mocking the new OrganisationService() constructor call. Instead we can setup a getter method for the OrganisationService, then mock it....
Mockery mock method inside closure
unit-testing,laravel-4,mocking,phpunit,mockery
A mocked class does not execute the real code by default. If you mock the helper it will check that the calls are being made but won't execute the anonymous function. With mockery, you can configure the expectation so that the real method will be executed: passthru(); Try this: $helperMock...
Mocking a method outside of a class
python,unit-testing,mocking,wsgi,assert
What you need to do in your unittest to test http_exception return case is: patch cred_check.methodA to return False Instantiate a MyClass() object (you can also use a Mock instead) Call MyClass.methodB() where you can pass a MagicMock as request and check if the return value is an instance of...
Mock user input()
python,testing,input,mocking,flexmock
ask doesn't return after the first too-young age; it loops until an appropriate age is entered. As written, you'll need to supply all the strings it might read, then do all your assertions after ask returns. @mock.patch('builtins.input', side_effect=['11', '13', 'Bob']) def test_bad_params(self, input): ask() output = sys.stdout.getline().strip() assert output ==...
NSubstitute: When…Do not working while mocking void method
NSubstitute is intended to be used with interfaces. It has some limitations with classes like only being able to work for virtual members. From their documentation: Warning: Substituting for classes can have some nasty side-effects. For starters, NSubstitute can only work with virtual members of the class, so any non-virtual...
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...
NSubstitute mock a void method with out parameters
c#,unit-testing,testing,mocking,nsubstitute
out parameters are updated using their parameter position as an index. It's explained in the Returns documentation for NSubstitute. So, for your particular case, you are populating the second and third parameters, so you should be setting up your call like this: customerDataAccess.When(x => x.GetCustomerWithAddresses(1, out customers, out addresses)) .Do(x...
Mockito rule not being applied
java,unit-testing,junit,mocking,mockito
String currentAlphabet; private ruleSetUp() { // [snip] Mockito.doReturn(currentAlphabet).when(dummyObj).innerMethod( Mockito.anyInt(), Mockito.anyInt()); } Mockito returns null for every call to innerMethod because you're telling it to. Though you set currentAlphabet whenever next is called, you don't set anything until then. At the time that ruleSetup is called, currentAlphabet is null, so...
Unit testing a fluent interface with Mockito
java,unit-testing,mocking,mockito,builder-pattern
Use PowerMockito instead. There you can define that whenever you have a call to a constructor of DAO, return my mocked object instead of returning actual DAO object. Please refer this to learn how to use PowerMockito.
How to mock http.Head()
The http.Head function simply calls the Head method on the default HTTP client (exposed as http.DefaultClient). By replacing the default client within your test, you can change the behaviour of these standard library functions. In particular, you will want a client that sets a custom transport (any object implementing the...
JMockit: Overriding @Mocked class

How can I unit test node.js functions with Mocha?
node.js,unit-testing,mocking,mocha
With mocha tests you have an optional done callback that makes testing async functions easier, like this: it('should send a verify SMS', function(done) { var data = {}; var code = 1; methods.sendVerifySms(code, data) .then(function(actualCode) { should(actualCode).equal(code); done(); }); }); I would also have some feedback to offer on the...
Mocking stored procedure's output parameter
c#,.net,unit-testing,mocking,moq
After reading the MOQ's manual 3rd time I finally was able to find the way to do this. That was surprisingly simple: mockObjectContext.Setup(m => m.SP_IsUserAllowedToDoThings(It.IsAny<string>(), It.IsAny<string>(), It.IsAny<ObjectParameter>())).Callback<string, string, ObjectParameter>((a, b, c) => { c.Value = true; }); ...
How to check JSON in response body with mockMvc
java,spring,junit,mocking,spring-test-mvc
The 406 Not Acceptable status code means that Spring couldn't convert the object to json. You can either make your controller method return a String and do return json.toString(); or configure your own HandlerMethodReturnValueHandler.

Python unittest mock an API key

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...
