  • Unit testing the app.config file with NUnit

    - by Dana
    When you guys are unit testing an application that relies on values from an app.config file? How do you test that those values are read in correctly and how your program reacts to incorrect values entered into a config file? It would be ridiculous to have to modify the config file for the NUnit app, but I can't read in the values from the app.config I want to test. Edit: I think I should clarify perhaps. I'm not worried about the ConfigurationManager failing to read the values, but I am concerned with testing how my program reacts to the values read in.

  • Entity Framework 4.0 Unit Testing

    - by Steve Ward
    Hi, I've implemented unit testing along the lines of this article with a fake object context and IObjectSet with POCO in EF4. http://blogs.msdn.com/adonet/archive/2009/12/17/test-driven-development-walkthrough-with-the-entity-framework-4-0.aspx But I'm unsure how to implement a couple of methods on my fake object context for testing. I have CreateQuery and ExecuteFunction methods on my object context interface so that I can execute ESQL and Stored Procedures but I cant (easily) implement them in my fake object context. An alternative would be to use a test double of my repository instead of a double of my object context as suggested here: http://social.msdn.microsoft.com/Forums/en-US/adonetefx/thread/c4921443-e8a3-4414-92dd-eba1480a07ad/ But this would mean my real repository isnt being tested and would seem to just bypass the issue. Can anyone offer any recommendations?

  • Creating TCP network errors for unit testing

    - by Robert S. Barnes
    I'd like to create various network errors during testing. I'm using the Berkely sockets API directly in C++ on Linux. I'm running a mock server in another thread from within Boost.Test which listens on localhost. For instance, I'd like to create a timeout during connect. So far I've tried not calling accept in my mock server and setting the backlog to 1, then making multiple connections, but all seem to successfully connect. I would think that if there wasn't room in the backlog queue I would at least get a connection refused error if not a timeout. I'd like to do this all programatically if possible, but I'd consider using something external like IPchains to intentionally drop certain packets to certain ports during testing, but I'd need to automate creating and removing rules so I could do it from within my Boost.Test unit tests. I suppose I could mock the various system calls involved, but I'd rather go through a real TCP stack if possible. Ideas?

  • rake test and test_structure.sql

    - by korinthe
    First of all, I have to run "rake RAILS_ENV=test ..." to get the test suites to hit my test DB. Annoying but ok to live with. However when I do so, I get a long stream of errors like so: > rake RAILS_ENV=test -I test test:units psql:/path/to/project/db/test_structure.sql:33: ERROR: function "armor" already exists with same argument types [and many more] It looks like some DB definitions are getting unnecessarily reloaded. I can't find any mention of this on Google, so I was wondering whether others have seen this? I am using a PostgreSQL database with the following in my environment.rb: config.active_record.schema_format = :sql and using Rails 2.3.5 with rake 0.8.7.

  • Unit testing task queues in AppEngine

    - by Swizec Teller
    For a very long time now I've been using task queues on AppEngine to schedule tasks, just the way I'm supposed to. But what I've always been wondering is how does one write tests for that? Until now I've simply made tests to make sure an error doesn't occur on the API that queues a task and then wrote the more proper tests for the API executing the task. However lately I've started feeling a bit unsatisfied by this and I'm searching for a way to actually test that the correct task has been added to the correct queue. Hopefully this can be done better than simply by deploying the code and hoping for the best. I'm using django-nonrel, if that has any bearing on the answer. To recap: How can a unit test be written to confirm tasks have been queued?

  • Why can't I write just a try with no catch or finally?

    - by Camilo Martin
    Sometimes I do this and I've seen others doing it too: VB: Try DontWannaCatchIt() Catch End Try C#: try { DontWannaCatchIt(); } catch {} I know I should catch every important exception and do something about it, but sometimes it's not important to - or am I doing something wrong? Is this usage of the try block incorrect, and the requirement of at least one catch or finally block an indication of it?

  • Unit testing ASP.NET MVC 2 routes with areas bails out on AreaRegistration.RegisterAllAreas()

    - by Sandor Drieënhuizen
    I'm unit testing my routes in ASP.NET MVC 2. I'm using MSTest and I'm using areas as well. When I call AreaRegistration.RegisterAllAreas() however, it throws this exception: System.InvalidOperationException: System.InvalidOperationException: This method cannot be called during the application's pre-start initialization stage.. OK, so I reckon I can't call it from my class initializer. But when can I call it? I don't have an Application_Start in my test obviously.

  • Unit of Work Pattern in .Net

    - by Jazza
    Does anyone have any concrete examples of a simple Unit of Work pattern in C# or Visual Basic that would handle the following scenario? I'm writing a WinForms application in which a customer can have multiple addresses associated with it. The user can add, edit and delete addresses belonging to the customer before the customer is saved back to the database. Therefore, at the time of saving, all the original addresses need to be deleted from the database and the new addresses added in a single transaction.

  • Embedded systems code with good unit tests?

    - by rmk
    I am looking at approaches to Unit Test embedded systems code written in C. At the same time, I am also looking for a good UT framework that I can use. The framework should have a reasonably small number of dependencies. Any great Open-source products that have good UTs?

  • Unit testing Jade

    - by Strawberry
    Hi, What techniques and design strategies have people used to aid in unit testing Jade applications? In particular, how do people typically go about testing Behaviours - which are tightly coupled to the Agent instance and the Jade environment? I'm aware of the JadeMX project, but this appears to be geared more towards system testing - in particular the message exchange between collaborating agents. Thanks.

  • unit, integration and system tests for PHP applications

    - by Sara
    Hi, We were given an assignment to develop a prototype for a customer community. It was suggested PHP as the programming language. (but we're not supposed to actually code it, just a prototype with documentation is required) I'm wondering what are the best practices/ tools used in Unit testing, Integration Testing and System testing for such a php app Thanks

  • Unit of Work pattern and persistence

    - by Mosh
    Hello, I have been reading about Unit of Work pattern but I am confused about how the UoW actually persists data. When we commit the changes, UoW should iterate through the list of Added, Updated and Deleted objects and somehow find a class responsible to Add, Update, Delete objects of a certain type. I couldn't find an example showing this technique. Any advice on this would be greatly appreciated. Mosh

  • Is automated unit-testing on Cognos possible ?

    - by Evandro
    Hi everyone ! Does anyone know if there is any tool or a way to apply automated unit testing in report studio and/or framework manager ? When some regression tests are required and I need to run report by report, on the traditional way, it really bothers me. Best regards, Evandro
