  • Unit testing a 'legacy' WPF Application

    - by sc_ray
    The product I have been working on has been in development for the past six years. It started as a generic data entry portal into an insanely complex part WPF/part legacy application. The system has been developed for all these years without a single Unit test in its fold. Now, the point has been raised for a comprehensive unit testing framework. I have been recruited recently to work on this product and have been tasked to get the 'Testing' in order. Since the team that worked on the product for the last six years adopted 'Agile', the project lacks any documentation of the business rules or any design documents. I have been trying to write unit tests for some of the modules. But I am not sure what to Mock, how to setup my Test fixture and eventually what to Test for, since a casual glance of the methods does not reveal its intentions. Also, it has come to my attention that the code was not developed with a particular methodology in mind. Given the situation, I was wondering if the good people of Stackoverflow could provide me with some advise on how to salvage this situation. I have heard about the book 'Working with Legacy Code' that has something to say about this general situation but I was thinking about getting some pointers from individuals who have encountered similar situations within the technology stack(C#,VB,C++,.NET 3.5,WCF,SQL Server 2005).

  • Testing Visual Studio 2008 Package

    - by Dave Swersky
    I'm developing a Visual Studio Integration Package. When I try to run the Unit Tests that are included in the unit test project that is included in the template I get the following failure on the first test: The test adapter 'VsIdeHostAdapter' threw an exception while running test 'MenuItemCallback'. Call was rejected by callee. (Exception from HRESULT: 0x80010001 (RPC_E_CALL_REJECTED)) It's intermittent- a new instance of Visual Studio always spins up, then sometimes it works but usually fails.

  • How do I configure integration tests using rspec 2?

    - by Jamie Monserrate
    I need to have different settings for my unit tests and different settings for my integration tests. Example For unit tests, I would like to do WebMock.disable_net_connect!(:allow_localhost => true) And for integration tests, I would like to do WebMock.allow_net_connect! Also, before the start of an integration test, I would like to make sure that solr is started. Hence I want to be able to call config.before(:suite) do SunspotStarter.start end BUT, only for integration tests. I do not want to start my solr if its a unit test. How do I keep their configurations separate? Right now, I have solved this by keeping my integration tests in a folder outside the spec folder, which has its own spec_helper. Is there any better way?

  • SQL Server Editions and Integration Services

    The SQL Server 2005 and SQL Server 2008 product family has quite a few editions now, so what does this mean for SQL Server Integration Services? Starting from the bottom we have the free edition known as Express, and the entry level Workgroup edition, as well as the new Web edition. None of these three include the full SSIS product, but they do all include the SQL Server Import and Export Wizard, with access to basic data sources but nothing more, so for simple loading and extraction of data this should suffice. You will not be able to build packages though, this is just a one shot deal aimed at using the wizard on an ad-hoc basis. To get the full power of Integration Services you need to start with Standard edition. This includes the BI Development Studio, for building your own packages, and fully functional IDE integrated into Visual Studio. (You get the full VS 2005/2008 IDE with the product). All core functions will be available but with a restricted set of transformations and tasks. The SQL Server 2005 Features Comparison or Features Supported by the Editions of SQL Server 2008 describes standard edition as having basic transforms, compared to Enterprise which includes the advanced transforms. I think basic is a little harsh considering the power you get with Standard, but the advanced covers the truly ground-breaking capabilities of data mining, text mining and cleansing or fuzzy transforms. The power of performing these operations within your ETL pipeline should not be underestimated, but not all processes will require these capabilities, so it seems like a reasonable delineation. Thankfully there are no feature limitations or artificial governors within Standard compared to Enterprise. The same control flow and data flow engines underpin both editions, with the same configuration and deployment options allowing you to work seamlessly between environments and editions if using the common components. In fact there are no govenors at all in SSIS, so whilst the SQL Database engine is limited to 4 CPUs in Standard edition, SSIS is only limited by the base operating system. The advanced transforms only available with Enterprise edition: Data Mining Training Destination Data Mining Query Component Fuzzy Grouping Fuzzy Lookup Term Extraction Term Lookup Dimension Processing Destination Partition Processing Destination The advanced tasks only available with Enterprise edition: Data Mining Query Task So in summary, if you want SQL Server Integration Services, you need SQL Server Standard edition, and for the more advanced tasks and transforms you need SQL Server Enterprise edition. To recap, the answer to the often asked question is no, SQL Server Integration Services is not available in SQL Server Express or Workgroup editions.

  • Optimized Integration between Oracle Data Integrator and Oracle GoldenGate

    - by Alex Kotopoulis
    The Journalizing Knowledge Module for Oracle GoldenGate's CDC mechanism has just been released as part of the ODI 10.1.3.6_02 patch, and a very useful post from Mark Rittman gives detailed instructions about how to set it up in a sample environment. This integration combines the best of two worlds, the non-invasive, highly performant data replication from Oracle GoldenGate with the innovative and scalable EL-T concept from ODI to perform complex loads into real-time data warehouses. Please also check out the new datasheet about this integration.

  • 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.

  • Django - testing using large tables of static data

    - by Michael B
    I am using "manage.py test" along with a JSON fixture I created using using 'dumpdata' My problem is that several of the tables in the fixture are very large (for example one containing the names of all cities in the US) which makes running a test incredibly slow. Seeing as several of these tables are never modified by the program (eg - the city names will never need to be modified), it doesn't make much sense to create and tear down these tables for every test run. Is there a better way to be testing this code using this kind of data?

    - by anshu
    I have been trying using MS VSTS 2008, no luck so far.. After the redirection from server to accomodate the sessionID in URL, the test fails during the first time recording. I am open to looking at other tools which are not very expensive. Does anyone have any experience using any tool for testing cookieless sessionID website?

  • CSharp: Testing a Generic Class

    - by Jonas Gorauskas
    More than a question, per se, this is an attempt to compare notes with other people. I wrote a generic History class that emulates the functionality of a browser's history. I am trying to wrap my head around how far to go when writing unit tests for it. I am using NUnit. Please share your testing approaches below. The full code for the History class is here (http://pastebin.com/ZGKK2V84).

  • Override variables while testing a standalone Perl script

    - by BrianH
    There is a Perl script in our environment that I now need to maintain. It is full of bad practices, including using (and re-using) global variables throughout the script. Before I start making changes to the script, I was going to try to write some test scripts so I can have a good regression base. To do this, I was going to use a method described on this page. I was starting by writing tests for a single subroutine. I put this line somewhat near the top of the script I am testing: return 1 if ( caller() ); That way, in my test script, I can require 'script_to_test.pl'; and it won't execute the whole script. The first subroutine I was going to test makes a lot of use of global variables that are set throughout the script. My thought was to try to override these variables in my test script, something like this: require_ok('script_to_test.pl'); $var_from_other_script = 'Override Value'; ok( sub_from_other_script() ); Unfortunately (for me), the script I am testing has a massive "my" block at the top, where it declares all variables used in the script. This prevents my test script from seeing/changing the variables in the script I'm running tests against. I've played with Exporter, Test::Mock..., and some other modules, but it looks like if I want to be able to change any variables I am going to have to modify the other script in some fashion. My goal is to not change the other script, but to get some good tests running so when I do start changing the other script, I can make sure I didn't break anything. The script is about 10,000 lines (3,000 of them in the main block), so I'm afraid that if I start changing things, I will affect other parts of the code, so having a good test suite would help. Is this possible? Can a calling script modify variables in another script declared with "my"? And please don't jump in with answers like, "Just re-write the script from scratch", etc. That may be the best solution, but it doesn't answer my question, and we don't have the time/resources for a re-write.

  • Testing Mobile Sites

    - by Kyle Rozendo
    Hi All, We are about to launch a mobile site and are wondering what the best way of testing across as many mobile browsers as possible would be? This could be a company that does this sort of thing, or a way in which to do it in-house, we're not being picky. Thanks, Kyle
