run in a single thread per JVM. Not the answer you're looking for? change the behavior of the real object. when (mockedIntList.get ( any ())).thenReturn (3); #2) any (java language class) - Example: any (ClassUnderTest.class) - This is a more specific variant of any () and will accept only objects of the class type that's mentioned as the template parameter. its common to declare interactions at mock creation time or in a Even if you have never seen Groovy/Spock before, the syntax of the unit test should be familiar, as the code is deliberately written to be Java-like. The Java world has no shortage of popular and mature mocking frameworks: JMock, Such an assignments happen before the method interceptor is called, for this simply check whether invocation.arguments[i] is null or not. Either of them must always be present; How can I control PNP and NPN transistors together from one pin? For a mocking example, lets assume that we have the following class in our application: This class has two external dependencies, a class that sends emails and an invoice database. Therefore, spock passes Object [] { ArrayList [ byte [] ] } to the closure. Using the os property, the previous example can be rewritten as: To execute a feature method under certain conditions, annotate it with spock.lang.Requires, Given a class Person with properties name and age, and a data variable person of type Person, the By default it retries an iteration 3 times with 0 delay if either an Exception or AssertionError has been thrown, all this is configurable. Spock supports the creation of mocks using the static Mock() method. There are several mocking frameworks in the Java world, but the most popular one is Mockito. The argument to Official support for Java 1.8, Groovy 2.3 and Groovy 2.4. Improve in assertions Spock now uses DefaultGroovyMethods.dump instead of toString if a class doesnt override the default Object.toString. Note that we dont have to pass the message argument along; this is taken care of automatically. This is called once for each feature method where the annotation is applied with the annotation instance as first The use case is to annotate tests that can not yet run but should already be committed. If so, the retries defined in the subclass are applied to all feature A simple toy example that is failing in an identical manner to my production code follows: I was relying on the behavior described in the Spock docs for Computing Return Values under Interaction Based Testing. Unlike Junit, Spock does not use assert statements. For applying the magic of your extension, there are various interception points, where you can attach interceptors from I want to verify that the eventBus.fireEvent(..) gets called once with an Event with type SaveCommentEvent and construction parameters oldComment and newComment. We use right-shift (>>) to state that when the method getPrimaryColour is called, the Enum value Red will be returned. In those cases, it makes sense to move the stub creation process to a reusable method, removing code duplication. Im using grails 4 so I cant use the mockFor(HTMLCodec) and Mock(HTMLCodec) not possible since spock cant mock final classes It might be better to change the design of the code under specification.). Sometimes we need more detail, and instead of looking only at the method call itself, we are also interested in the arguments. to use them together with GroovySpy. If there is no paticular reason why you don't use the standard gorm M:N Relationship, you could just implement it like this: class AccountRecord { static hasMany = [owners: IndividualRecord] } class IndividualRecord { String uniqueId String secundaryId static belongsTo = AccountRecord static hasMany = [accounts: AccountRecord] } http://docs.spockframework.org/en/spock-0.7-groovy-1.8). You can add more tests or even combine multiple tests framework by adding more jobs into the Tests block. when then configuration object is to be injected into the extension and you will also get an error when the It effectively replaces all instances of that type and makes them and is either a multiplication (*) or a right-shift (>>, >>>) operation, then it is considered equal to itself, has a unique hash code, and a string representation that includes the name of the type it represents. I'm not familiar with Spock's history, but I wonder if it was forked from the original Groovy testing/mocking framework and inherited this issue? issue. Lets say we want to test using a list of 20 customers. Spock. Spock has spring namespace support, so if you declare the spock namespace with xmlns:spock="http://www.spockframework.org/spring" you get access to the convenience functions for creating mocks. There may be cases where we want to access the arguments passed into the mock method and use those arguments in the return value of the mock call. Spock provides a way to do this by using a closure with the same number and type of arguments as the mock method. that describe expected features (properties, aspects) exhibited by a system of interest. Specs, Spec base classes and third-party extensions may have be recompiled in order to work with Spock 1.0. Spock will then automatically create exactly one instance of the configuration object per Spock run, apply the Interaction Based Testing - Spock driven local extensions. For each interception point there can of course For the first test, we assume the customer has an outstanding invoice (line invoiceStorage.hasOutstandingInvoice(sampleCustomer) >> true). to state the conditions under which a method gets executed, rather than the conditions under which it gets ignored. like attaching interceptors to various interception points as described in the chapter Interceptors. labelled) block - in fact, the presence of an explicit block is iteration of the method.
