  • Unit testing huge applications - Proven methodologies?

    - by NLV
    Hello members I've been working in windows forms applications and ASP.Net applications for the past 10 months. I've always wondered how to perform proper unit testing on the complete application in a robust manner covering all the scenarios. I've the following questions regarding them - What are the standard mechanisms in performing unit testing and writing test cases? Does the methodologies change based on the application nature such as Windows Forms, Web applications etc? What is the best approach to make sure we cover all the scenarios? Any popular books on this? Popular tools for performing unit testing?

  • Visual Studio Unit Testing of Windows Forms

    - by GWLlosa
    We're working on a project here in Visual Studio 2008. We're using the built-in testing suite provided with it (the Microsoft.VisualStudio.TestTools.UnitTesting namespace). It turns out, that much to our chagrin, a great deal of complexity (and therefore errors) have wound up coded into our UI layer. While our unit tests do a decent job of covering our business layer, our UI layer is a constant source of irritation. We'd ideally like to unit-test that, as well. Does anyone know of a good "Microsoft-compatible" way of doing that in visual studio? Will it introduce some sort of conflict to 'mix' unit testing frameworks like nUnitForms with the Microsoft stuff? Are there any obvious bear traps I should be aware of with unit-testing forms?

  • Getting started with Rails testing

    - by yuval
    I asked a question about different testing frameworks yesterday. This question can be found here. Now that I have a better understanding of the different frameworks, I have a very simple question: With a basic understanding, but very limited experience with writing tests with rails' built in testing framework (basic assertions), would it be okay for me to jump directly to testing with RSpec, Webrat, and Cucamber? Thank you! As a side note: yes, this is an opinion based question, but I feel that the input received to this question is valuable enough to the community to keep this question open. Thanks.

  • Why is unit testing needed in iPhone / iPad ?

    - by Madhup
    Hi, I am developing an application for iPad application. I need to perform unit testing in the application. But I am not sure why I should do unit testing in this application. The applications in these environments are rather small for unit testing to be written. And since the iPhone sentestingkit is not well documented the implementation and wriiting test cases is so time consuming. So why should we waste time in this? And if we have to what should be the best approach to write test cases? Thanks, Madhup

  • Manually Dispatching a DocumentEvent for testing UI element validation code

    - by Bassam
    Hi. I'm testing a Swing GUI application using the UISpec4J testing framework. I'm testing validation code on a JTextField, but the framework does not support focus-change events, as it runs the application in a headless fashion. The text field has a DocumentEvent attached to it that activates the validation code. I'm trying to figure out how to dispatch the document event manually to activate the validation code. Trying to dispatch focus or mouse events manually haven't been working for me. Thanks for any help!

  • Unit testing with serialization mock objects in C++

    - by lhumongous
    Greetings, I'm fairly new to TDD and ran across a unit test that I'm not entirely sure how to address. Basically, I'm testing a couple of legacy class methods which read/write a binary stream to a file. The class functions take a serializable object as a parameter, which handles the actual reading/writing to the file. For testing this, I was thinking that I would need a serialization mock object that I would pass to this function. My initial thought was to have the mock object hold onto a (char*) which would dynamically allocate memory and memcpy the data. However, it seems like the mock object might be doing too much work, and might be beyond the scope of this particular test. Is my initial approach correct, or can anyone think of another way of correctly testing this? Thanks!

  • Silverlight unit testing (using NUnit)

    - by 1gn1ter
    I'm using NUnit for testing back-end. Unit tests are being executed while building (I'm using TeamCity for continuous building). Now I hove to test front-end (Silverlight 4.0). Because the tests are being executed while building, I have to simulate browser (TypeMock - is not free, isn't it?) could I use NUnit.Mocks somehow?. How to use NUnit for Silverlight testing? I've found WHITE framework could it help? Any other advises about software/frameworks to use for Silverlight unit testing?

  • Advice about testing an application before release?

    - by Troy
    I would like to get some tips from peer developers about how you go about testing an application you developed, prior to release to QA. Keep in mind, this is a small scale application (requirements are verbal), and so doing formal testing processes wont work, especially, since your boss told you to develop this app quick, push it out the door. Despite the time restraints, I would like to make sure it is bug free, however, numerous times in the past, I have had the app sent back to me because clicking the "Reset" button, messes up the other controls alignment etc. I know there are people out there that develop small scale apps fast, and send them out with minimal bugs. How can I achieve that? I researched this post, but it didnt quite answer my question. Testing your code before releasing to QA

  • More on Map Testing

    - by Michael Stephenson
    I have been chatting with Maurice den Heijer recently about his codeplex project for the BizTalk Map Testing Framework (http://mtf.codeplex.com/). Some of you may remember the article I did for BizTalk 2009 and 2006 about how to test maps but with Maurice's project he is effectively looking at how to improve productivity and quality by building some useful testing features within the framework to simplify the process of testing maps. As part of our discussion we realized that we both had slightly different approaches to how we validate the output from the map. Put simple Maurice does some xpath validation of the data in various nodes where as my approach for most standard cases is to use serialization to allow you to validate the output using normal MSTest assertions. I'm not really going to go into the pro's and con's of each approach because I think there is a place for both and also I'm sure others have various approaches which work too. What would be great is for the map testing framework to provide support for different ways of testing which can cover everything from simple cases to some very specialized scenarios. So as agreed with Maurice I have done the sample which I will talk about in the rest of this article to show how we can use the serialization approach to create and compare the input and output from a map in normal development testing. Prerequisites One of the common patterns I usually implement when developing BizTalk solutions is to use xsd.exe to create .net classes for most of the schemas used within the solution. In the testing pattern I will take advantage of these .net classes. The Map In this sample the map we will use is very simple and just concatenates some data from the input message to the output message. Hopefully the below picture illustrates this well. The Test In the test I'm basically taking the following actions: Use the .net class generated from the schema to create an input message for the map Serialize the input object to a file Run the map from .net using the standard BizTalk test method which was generated for running the map Deserialize the output file from the map execution to a .net class representing the output schema Use MsTest assertions to validate things about the output message The below picture shows this: As you can see the code for this is pretty simple and it's all strongly typed which means changes to my schema which can affect the tests can be easily picked up as compilation errors. I can then chose to have one test which validates most of the output from the map, or to have many specific tests covering individual scenarios within the map. Summary Hopefully this post illustrates a powerful yet simple way of effectively testing many BizTalk mapping scenarios. I will probably have more conversations with Maurice about these approaches and perhaps some of the above will be included in the mapping test framework.   The sample can be downloaded from here: http://cid-983a58358c675769.office.live.com/self.aspx/Blog%20Samples/More%20Map%20Testing/MapTestSample.zip

  • Should library classes be wrapped before using them in unit testing?

    - by Songo
    I'm doing unit testing and in one of my classes I need to send a mail from one of the methods, so using constructor injection I inject an instance of Zend_Mail class which is in Zend framework. Example: class Logger{ private $mailer; function __construct(Zend_Mail $mail){ $this->mail=$mail; } function toBeTestedFunction(){ //Some code $this->mail->setTo('some value'); $this->mail->setSubject('some value'); $this->mail->setBody('some value'); $this->mail->send(); //Some } } However, Unit testing demands that I test one component at a time, so I need to mock the Zend_Mail class. In addition I'm violating the Dependency Inversion principle as my Logger class now depends on concretion not abstraction. Does that mean that I can never use a library class directly and must always wrap it in a class of my own? Example: interface Mailer{ public function setTo($to); public function setSubject($subject); public function setBody($body); public function send(); } class MyMailer implements Mailer{ private $mailer; function __construct(){ $this->mail=new Zend_Mail; //The class isn't injected this time } function setTo($to){ $this->mailer->setTo($to); } //implement the rest of the interface functions similarly } And now my Logger class can be happy :D class Logger{ private $mailer; function __construct(Mailer $mail){ $this->mail=$mail; } //rest of the code unchanged } Questions: Although I solved the mocking problem by introducing an interface, I have created a totally new class Mailer that now needs to be unit tested although it only wraps Zend_Mail which is already unit tested by the Zend team. Is there a better approach to all this? Zend_Mail's send() function could actually have a Zend_Transport object when called (i.e. public function send($transport = null)). Does this make the idea of a wrapper class more appealing? The code is in PHP, but answers doesn't have to be. This is more of a design issue than a language specific feature

  • Is there such a tool for testing

    - by kjack
    Say one has a structural codebase where lots of the code is in GUI control events and has no tests. So such code, to my knowledge is not suitable for unit testing Is there a tool that can test each routine automatically replacing references to code elements external to the routine (be they functions, variables or GUI controls) with appropriate mocks(?) and record the results in a database for later comparison after code changes? So the testing program would have the duty of writing, running and reporting tests with minimal intervention?

  • Functional testing of a 3-rd party java program

    - by Dmitri Nesteruk
    I have a 3-rd party java application (I don't own source code) and I want to perform functional testing on it, similar to the way it's done in watin/watij/selenium/nunitforms etc. Can anyone suggest a library that I can use to do this sort of testing. What I'm interested in is clicking the applet's buttons, reading off text values, and the like. Thanks!

  • Front-end testing - tools Selenium RC

    - by Ekaterina
    Hello people, I am wondering what tool(s) do you use for front-end testing... Currently I am using Selenium RC as tool to test the front-end. I am quite happy with the result as I managed to integrate it with the ms build process etc. The problem with Selenium tests is that they are not always reliable especially if you browse with something else than Firefox. I am looking for open source alternatives (tools for front-end testing)?

  • Unit testing in python?

    - by yossi.ittach
    Hey - I'm new to python , and I'm having a hard time grasping the concept of Unit testing in python. I'm coming from Java - so unit testing makes sense because - well , there you actually have a unit - A Class. But a Python class is not necessarily the same as a Java class , and the way I use Python - as a scripting language - is more functional then OOP - So what do you "unit test" in Python ? A flow? Thanks!
