contract

问题 I am using pactNet to test an API which should return an array of a flexible length. If i call "myApi/items/" it should return a list of items where the consumer does not know the exact size of. So the answer should look like this: [ { "id": "1", "description": "foo" }, { "id": "2", "description": "foo2" }, { "id": "3", "description": "foo3" } ] or this: [ { "id": "4", "description": "foo4" }, { "id": "2", "description": "foo2" } ] How do I create the contract for this interaction? In the

问题 I'm interested in studying the recently accepted contract programming for C++20 for learning and investigation purpose. As I'm looking around for compiler support, I'm disappointed to not find any. Both gcc and clang are quite clear they do not support this feature within their --std=c++2a mode. Since the approval is pretty recent, I'm not too surprised that current compilers do not support the exact semantic proposed. What is more surprising to me though is that there is absolutely nothing,

问题 I'm currently trying to learn Ruby and I'm trying to understand more about what it offers in terms of encapsulation and contracts. In C# a contract can be defined using an interface. A class which implements the interface must fulfil the terms within the contract by providing an implementation for each method and property (and maybe other things) defined. The individual class that implements an interface can do whatever it needs within the scope of the methods defined by the contract, so long

问题 Is contract to interface as object is to class? What is the need to differentiate identical things like this, from the code to the executing code? I sort of get the idea behind naming a class a class and the instantiated executing class an object, but overall, is that the only reason for these semi-redundant terms? 回答1: Not really. There are four terms here, so I'll go over each of them: Interface An interface is an abstract class (in languages like Java where there is no multiple inheritance

问题 I'm trying to use Cofoja, the Google library for contract programming. I've copied/pasted the build file wich I'm able to compile my library with succesfully. But when I start adding one annotation to specify a simple contract rule, I cannot compile anymore and get this console output : build: [javac] C:\Users\Admin\test\Seismi\build.xml:24: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds [javac] Compiling 2 source files to C

问题 This is more of a theoretical question. If I have an arbitrary collection c that isn't ordered and I obtain two java.util.Iterator s by calling c.iterator() twice, do both iterators have to return c 's elements in the same order? I mean, in practice they probably always will, but are they forced to do so by contract? Thanks, Jan 回答1: No they are not. "There are no guarantees concerning the order in which the elements are returned (unless this collection is an instance of some class that

问题 I've recently watched Integration Tests are a Scam by J. B. Rainsberger and am now looking for more material on the subject. I have to say, I'm shocked by how much we're doing wrong, (i.e. integration testing when we should unit test), intrigued by the concepts described by Rainsberger but also confused about how to apply them. I would like to have more of the described collaboration tests and contract tests but I don't know where to start. The only things that got stuck in my mind are the 4

问题 In other words: How to change wcf service contract to remove additional "message's" wrapper from soap message (adopt wsdl)? I have created WCF service which contract is: [ServiceContract(Namespace = "http://blabla/", Name = "DiagnosticApplication")] public interface IReceiveApplication { [OperationContract] string Test(XmlElement e); } So my SC accepts now such messages <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:epr="http://blabla/"> <soapenv:Header/>

问题 Here is the typical way of accomplishing this goal: public void myContractualMethod(final String x, final Set<String> y) { if ((x == null) || (x.isEmpty())) { throw new IllegalArgumentException("x cannot be null or empty"); } if (y == null) { throw new IllegalArgumentException("y cannot be null"); } // Now I can actually start writing purposeful // code to accomplish the goal of this method I think this solution is ugly. Your methods quickly fill up with boilerplate code checking the valid
