  • Practical refactoring using unit tests

    - by awhite
    Having just read the first four chapters of Refactoring: Improving the Design of Existing Code, I embarked on my first refactoring and almost immediately came to a roadblock. It stems from the requirement that before you begin refactoring, you should put unit tests around the legacy code. That allows you to be sure your refactoring didn't change what the original code did (only how it did it). So my first question is this: how do I unit-test a method in legacy code? How can I put a unit test around a 500 line (if I'm lucky) method that doesn't do just one task? It seems to me that I would have to refactor my legacy code just to make it unit-testable. Does anyone have any experience refactoring using unit tests? And, if so, do you have any practical examples you can share with me? My second question is somewhat hard to explain. Here's an example: I want to refactor a legacy method that populates an object from a database record. Wouldn't I have to write a unit test that compares an object retrieved using the old method, with an object retrieved using my refactored method? Otherwise, how would I know that my refactored method produces the same results as the old method? If that is true, then how long do I leave the old deprecated method in the source code? Do I just whack it after I test a few different records? Or, do I need to keep it around for a while in case I encounter a bug in my refactored code? Lastly, since a couple people have asked...the legacy code was originally written in VB6 and then ported to VB.NET with minimal architecture changes.

  • documenting black-box test cases

    - by Blux
    Hi everyone, I want to write an initial (black box) test cases for one of my university projects. I haven't started coding yet, I'm still in completing the SRS document and i should specify the test cases i'm going to implement after the coding. The project is web based, and i should follow this template in each test case: +++++ Test case ID: Author: Initial state: Preconditions: Use Case: Test input: Expected output: ++++++ The thing is, i don't know what is the difference between "initial state" and "preconditions". In some of the test cases it's hard to differentiate between them. Like in "Edit Page" what should be the initial state and what should be the preconditions? any help will appreciated.=)

  • ClassCleanup in MSTest is static, but the build server uses nunit to run the unit tests. How can i a

    - by Kettenbach
    Hi All, MSTest has a [ClassCleanup()] attribute, which needs to be static as far as I can tell. I like to run through after my unit tests have run,and clean up my database. This all works great, however when I go to our build server and use our Nant build script, it seems like the unit tests are run with NUnit. NUnit doesn't seem to like the cleanup method to be static. It therefore ignores my tests in that class. What can I do to remedy this? I prefer to not use [TestCleanUp()] as that is run after each test. Does anyone have any suggestions? I know [TestCleanup()] aids in decoupling, but I really prefer the [ClassCleanup()] in this situation. Here is some example code. ////Use ClassCleanup to run code after all tests have run [ClassCleanup()] public static void MyFacadeTestCleanup() { UpdateCleanup(); } private static void UpdateCleanup() { DbCommand dbCommand; Database db; try { db = DatabaseFactory.CreateDatabase(TestConstants.DB_NAME); int rowsAffected; dbCommand = db.GetSqlStringCommand("DELETE FROM tblA WHERE biID=@biID"); db.AddInParameter(dbCommand, "biID", DbType.Int64, biToDelete); rowsAffected = db.ExecuteNonQuery(dbCommand); Debug.WriteLineIf(rowsAffected == TestConstants.ONE_ROW, string.Format("biId '{0}' was successfully deleted.", biToDelete)); } catch (SqlException ex) { } finally { dbCommand = null; db = null; biDelete = 0; } } Thanks for any pointers and yes i realize I'm not catching anything. I need to get passed this hurdle first. Cheers, ~ck in San Diego

  • Perl unit test - start a tcp server & continue

    - by John
    I am trying to write a unit test for a client server application. To test the client, in my unit test, I want to first start my tcp server (which itself is another perl file). I tried to start the tcp server by forking: if (! fork()) { system ("$^X server.pl") == 0 or die "couldn't start server" } So when I call "make test" after "perl Makefile.PL", this test starts & I can see the server starting but after that the unit test just hangs there. So I guess I need to start this server in background and I tried the "&" at the end to force it to start in background & then test to continue. But, I still couldn't succeed. What am I doing wrong? Thanks.

  • Managing logs/warnings in Python extensions

    - by Dimitri Tcaciuc
    TL;DR version: What do you use for configurable (and preferably captured) logging inside your C++ bits in a Python project? Details follow. Say you have a a few compiled .so modules that may need to do some error checking and warn user of (partially) incorrect data. Currently I'm having a pretty simplistic setup where I'm using logging framework from Python code and log4cxx library from C/C++. log4cxx log level is defined in a file (log4cxx.properties) and is currently fixed and I'm thinking how to make it more flexible. Couple of choices that I see: One way to control it would be to have a module-wide configuration call. # foo/__init__.py import sys from _foo import import bar, baz, configure_log configure_log(sys.stdout, WARNING) # tests/test_foo.py def test_foo(): # Maybe a custom context to change the logfile for # the module and restore it at the end. with CaptureLog(foo) as log: assert foo.bar() == 5 assert log.read() == "124.24 - foo - INFO - Bar returning 5" Have every compiled function that does logging accept optional log parameters. # foo.c int bar(PyObject* x, PyObject* logfile, PyObject* loglevel) { LoggerPtr logger = default_logger("foo"); if (logfile != Py_None) logger = file_logger(logfile, loglevel); ... } # tests/test_foo.py def test_foo(): with TemporaryFile() as logfile: assert foo.bar(logfile=logfile, loglevel=DEBUG) == 5 assert logfile.read() == "124.24 - foo - INFO - Bar returning 5" Some other way? Second one seems to be somewhat cleaner, but it requires function signature alteration (or using kwargs and parsing them). First one is.. probably somewhat awkward but sets up entire module in one go and removes logic from each individual function. What are your thoughts on this? I'm all ears to alternative solutions as well. Thanks,

  • Unit Test json output in Zend Framework

    - by lyle
    The Zend Tutorial lists many assertions to check the output generated by a request. http://framework.zend.com/manual/en/zend.test.phpunit.html But they all seem to assume that the output is html. I need to test json output instead. Are there any assertions helpful to check json, or is there at least a generic way to make assertions against the output? Anything that doesn't rely on the request outputting html?

  • Putting BigDecimal data into HSQLDB test database using DbUnit

    - by Denise
    Hi everyone, I'm using Hibernate JPA in my backend. I am writing a unit test using JUnit and DBUnit to insert a set of data into an in-memory HSQL database. My dataset contains: <order_line order_line_id="1" quantity="2" discount_price="0.3"/> Which maps to an OrderLine Java object where the discount_price column is defined as: @Column(name = "discount_price", precision = 12, scale = 2) private BigDecimal discountPrice; However, when I run my test case and assert that the discount price returned equals 0.3, the assertion fails and says that the stored value is 0. If I change the discount_price in the dataset to be 0.9, it rounds up to 1. I've checked to make sure HSQLDB isn't doing the rounding and it definitely isn't because I can insert an order line object using Java code with a value like 5.3 and it works fine. To me, it seems like DBUtils is for some reason rounding the number I've defined. Is there a way I can force this to not happen? Can anyone explain why it might be doing this? Thanks!

  • How to run White + SL4 UATs through TeamCity?

    - by Duncan Bayne
    After experiencing a series of unpleasant issues with TFS, including source code orruption and project management inflexibility, we (meaning the project team of which I'm a part) have decided to move from TFS 2010 to TeamCity + SVN + V1. I've managed to get our MSTest component and unit tests running as part of every build. However, our UATs are failing, and I was hoping for some advice from the TeamCity community as to best practices w.r.t. running web servers and interacting with the desktop. Each of our UAT fixtures starts a web server to host the site, like this: public static void StartWebServer() { var pathToSite = @"C:\projects\myproject\FrontEnd\MyProject.FrontEnd.Web"; var webServer = new Process { StartInfo = new ProcessStartInfo { Arguments = string.Format("/port:9150 /path:\"{0}\"", pathToSite), FileName = @"C:\Program Files (x86)\Common Files\microsoft shared\DevServer\10.0\WebDev.WebServer40.EXE" } }; webServer.Start(); } Needless to say, this doesn't work when running through TeamCity, as the pathToSite value is different each time. I'm hoping there is a way of determining the path into which the the code is checked out prior to building? That would allow me to point the web server at the right place. The other issue is that our UATs use White to drive the Silverlight UI through an instance of Internet Explorer: _browserWindow = InternetExplorer.Launch("http://localhost:9150/index.html#/Home", "Home - Windows Internet Explorer"); _document = _browserWindow.SilverlightDocument; I've ensured that the TeamCity service is granted the ability to interact with the desktop, and I've set the build agent machine up to log in automatically (an open session is a pre-requisite for White to work properly). Is that all I need to do or are there additional steps required?

  • Are TestContext.Properties read only ?

    - by DBJDBJ
    Using Visual Studio generate Test Unit class. Then comment out class initialization method. Inside it add your property, using the testContext argument. //Use ClassInitialize to run code before running the first test in the class [ClassInitialize()] public static void MyClassInitialize(TestContext testContext) { /* * Any user defined testContext.Properties * added here will be erased upon this method exit */ testContext.Properties.Add("key", 1 ) ; // above works but is lost } After leaving MyClassInitialize, properties defined by user are lost. Only the 10 "official" ones are left. This effectively means TestContext.Properties is read only, for users. Which is not clearly documented in MSDN. Please discuss. --DBJ

  • Separate seeds in PHPUnit

    How do I create a separate seed for some test inside one test class? PHPUnit documentation includes this example <?php require_once 'PHPUnit/Extensions/Database/TestCase.php'; class DatabaseTest extends PHPUnit_Extensions_Database_TestCase { protected function getConnection() { $pdo = new PDO('mysql:host=localhost;dbname=testdb', 'root', ''); return $this->createDefaultDBConnection($pdo, 'testdb'); } protected function getDataSet() { return $this->createFlatXMLDataSet(dirname(__FILE__).'/_files/bank-account-seed.xml'); } } ?> But in this example I have one seed for all the tests inside my class. Thank you for help.

  • How to make sure web services are kept stable from one release to the next?

    - by Tor Hovland
    The company where I work is a software vendor with a suite of applications. There are also a number of web services, and of course they have to be kept stable even if the applications change. We haven't always succeeded with this, and sometimes a customer finds that a service is not behaving as before after upgrading. We now want to handle this better. In general, web services shouldn't change, and if they have to, at least we will know about it and document the change. But how do we ensure this? One idea is to compare the WSDL files with the previous versions at every release. That will make sure the interfaces don't change, but it won't detect that the behavior changes, for example if a bug is introduced in some common library. Another idea is to build up a suite of service tests, for example using soapUI. But then we'll never know if we have covered enough cases. What are some best practices regarding this?

  • Find out which row caused the error

    - by Felipe Fiali
    I have a big fat query that's written dynamically to integrate some data. Basically what it does is query some tables, join some other ones, treat some data, and then insert it into a final table. The problem is that there's too much data, and we can't really trust the sources, because there could be some errored or inconsistent data. For example, I've spent almost an hour looking for an error while developing using a customer's database because somewhere in the middle of my big fat query there was an error converting some varchar to datetime. It turned out to be that they had some sales dating '2009-02-29', an out-of-range date. And yes, I know. Why was that stored as varchar? Well, the source database has 3 columns for dates, 'Month', 'Day' and 'Year'. I have no idea why it's like that, but still, it is. But how the hell would I treat that, if the source is not trustable? I can't HANDLE exceptions, I really need that it comes up to another level with the original message, but I wanted to provide some more info, so that the user could at least try to solve it before calling us. So I thought about displaying to the user the row number, or some ID that would at least give him some idea of what record he'd have to correct. That's also a hard job because there will be times when the integration will run up to 80000 records. And in an 80000 records integration, a single dummy error message: 'The conversion of a varchar data type to a datetime data type resulted in an out-of-range datetime value' means nothing at all. So any idea would be appreciated. Oh I'm using SQL Server 2005 with Service Pack 3.

  • Is it possible to unit test methods that rely on NHibernate Detached Criteria?

    - by Aim Kai
    I have tried to use Moq to unit test a method on a repository that uses the DetachedCriteria class. But I come up against a problem whereby I cannot actually mock the internal Criteria object that is built inside. Is there any way to mock detached criteria? Test Method [Test] [Category("UnitTest")] public void FindByNameSuccessTest() { //Mock hibernate here var sessionMock = new Mock<ISession>(); var sessionManager = new Mock<ISessionManager>(); var queryMock = new Mock<IQuery>(); var criteria = new Mock<ICriteria>(); var sessionIMock = new Mock<NHibernate.Engine.ISessionImplementor>(); var expectedRestriction = new Restriction {Id = 1, Name="Test"}; //Set up expected returns sessionManager.Setup(m => m.OpenSession()).Returns(sessionMock.Object); sessionMock.Setup(x => x.GetSessionImplementation()).Returns(sessionIMock.Object); queryMock.Setup(x => x.UniqueResult<SopRestriction>()).Returns(expectedRestriction); criteria.Setup(x => x.UniqueResult()).Returns(expectedRestriction); //Build repository var rep = new TestRepository(sessionManager.Object); //Call repostitory here to get list var returnR = rep.FindByName("Test"); Assert.That(returnR.Id == expectedRestriction.Id); } Repository Class public class TestRepository { protected readonly ISessionManager SessionManager; public virtual ISession Session { get { return SessionManager.OpenSession(); } } public TestRepository(ISessionManager sessionManager) { } public SopRestriction FindByName(string name) { var criteria = DetachedCriteria.For<Restriction>().Add<Restriction>(x => x.Name == name) return criteria.GetExecutableCriteria(Session).UniqueResult<T>(); } } Note I am using "NHibernate.LambdaExtensions" and "Castle.Facilities.NHibernateIntegration" here as well. Any help would be gratefully appreciated.
