copied!<p>If I understand the problem, you need to persist the results of a test for a later inspection or additional testing. It has often been reluctant to invest too much time in writing test code, but in this case I see no alternative immediately available.</p> <p>My advice is to decouple as much as possible the parts involved: the algorithm, the persistence layer (serialization/deserialization), its product and the verification code.</p> <p>It is possible also that later algorithms implementations can share the same interface, e.g.:</p> <pre><code>interface IMyAlgorithm { AbstractOutput DoSomething (InputData); } class ConcreteOutput : AbstractOutput { // Output for version XXX of your algorithm } class XXXAlgorithm { ConcreteOutput DoSomething (InputData inputData) // Version XXX of you alogorithm } } interface IPersistenceManager { Serialize(AbstractOutput output, string filename); AbstractOutput Deserialize(string filename) } class XXXPersistenceManager : IPersistenceManager { // Handle persistence for XXX hierarchy } class XXXTestFixture { void BuildObjectWithXXXAlgorithm() { IMyAlgorithm XXX = new XXXAlgorithm(); // run XXX here AbstractOutput objXXX = XXX.DoSomething(new InputData()); IPersistenceManager pmXXX = new XXXPersistenceManager(); pmXXX.Serialize(objXXX); } void VerifyThatXXXWorkAsExpected() { IPersistenceManager pmXXX = new XXXPersistenceManager(); AbstractOutput objXXX = pmXXX.Deserialize(path); // check object here } } </code></pre> <p>So when you need to create a new algorithm, say YYY, you create the corresponding hierarchy. Anyway I don't know details and this is just a draft of pseudocode, placed here only to put emphasis on loosely coupling application components.</p>
