  • From NUnit to crew equipment tests

    yet another chapter on my adventure helping a shopper undertake crew device. This time, the goal changed into to convert their NUnit test to team equipment checks.

    here's no longer a very intricate topic given the high-quality conversion device purchasable on gotdotnet (here), which in reality does all of the be just right for you. despite the fact, I did come across a number of issues.

    earlier than going into that, this is the fundamental manner I followed (fortunately, NUnit checks were alread 3X0-202y positioned in a single project (*.check)):

    a. Create a brand new check venture (named *.check.TS)

    b. Create the vital assignment folders

    c. Add the imperative references

    d. reproduction *.cs information from *.verify challenge to *.verify.TS

    e. Set assignment properties if vital (build place, postbuild movements, etc.)

    f. construct

    g. operate a look at various run with NUnit to investigate every thing is green

    h. Run the NUnit Converter

    i. eradicate Nunit references and construct once again

    j. Run exams in TS and assess outcomes with corresponding run in Nunit (g)

    okay. Commit pending adjustments

    When the test challenge is created, a .vsmdi and a .testrunconfig file are additionally created and added to the soluiton folder. If new tests are introduced to the answer, the vsmdi file will should be checked out. to see all the checks accessible for the answer, open .vsmdi file (it presents a listing view of the examine which will also be sorted and grouped -- n.b. the opportunity of grouping checks into lists is just obtainable when you have VS group edition for Testers).

    When changing a large assignment (about 2000 tests), I had to get across the following considerations:

    1. category Attribute

    classes don't exist in group device. The option is to use Description attribute or lists (lists are best attainable in the Tester edition). The converter device reacts as follows when discovering a category attribute:

  • If just one category on a test formulation, conversion turned into as follows: [Test, Category("sample")] --> [TestMethod(), TestProperty("Category", "sample")]
  • If just one class on a category, conversion become as follows: [TestFixture, Category("sample")] --> //category: "pattern"
  • If more than one category attribute, conversion didn't take place and NUnit conversion tool stops. My answer here became fairly primary: manual alternative (I used TextPad as editor)
  • exchange category("\(.+\)"),category("\(.+\)")\] through class("\1")]\n[TestProperty("Category","\2")\]

    for instance: [Test, Category("Business"), Category("More Business")] turns into [Test, Category("Business")] [TestProperty("Category","More Business")]

    notice that here's just a short lived solution to get the converter device to run until the conclusion. The final conversion offers this [TestMethod(), TestProperty("Category","Business")] [TestProperty("Category","More Business")] which is not correct because the equal property is used twice with diverse values. The 2nd property should still be modified to TestProperty("Category2","extra enterprise"), as an example (or use Description attribute instead).

  • 2. Partial courses

    Partial courses are not transformed as a result of they should not have the TestFixture attribute. You need to add it in order for the conversion to run, however afterwards remvoe the corresponding TestClass attribute (since it is a duplicate for the reason that the classification become partial).

    three. Static strategies.

    as a result of the TestFixtureSetUp conversion to ClassInitialize(), some methods needed to be transformed to static. additionally, given that the initialize method is now static, it can't be overriden anymore, however it does not really rely on account of aspect 4.

    Let me explain. The initial scenario turned into as follows: you have got a set of check classes that inherit from a mother or father type. This guardian class carries a verify set up system used with the aid of almost all babies. people that want some extra/distinctive initialization override the method. Like this:

    [TestFixture] public class BaseTest [TestFixtureSetUp] public virtual void InitializeTests() // do some initialization [TestFixture] public classification MyTest1 : BaseTest [Test] public voic SomeTest base.InitializeTests(); // do different issues [TestFixture] public classification MyTest2 : BaseTest [Test] public voic SomeOtherTest base.InitializeTests(); // do different issues public override void InitializeTests() // do some other initialization

    This scenario does not work anymore in group system on account of points3 and 4 (initialize methods are static and inheritance is not supported.

    4. Inheritance is not supported in team equipment unit assessments.

    yes, that's disappointing. This explains why the [TestFixtureSetUp] methods in a father or mother courses is not called. In team gadget trying out framework there are three attributes to initialize/clean up tests:

  • TestInitialize/CleanUp
  • ClassInitialize/Cleanup. It replaces your TestFixtureSetUp/TearDown however be aware that inheritance isn't supported.
  • AssemblyInitialize/Cleanup It runs once firstly of each formula within the assembly.
  • you should use these attributes. My advised answer is to change the TestFixtureSetUp attributes (converted to ClassInitialize()) in a guardian class via AssemblyInitialize and reorganize checks so that all exams needing this particular initialization are during this assembly.

    Given the illustration above, this potential putting off inheritance, including an AssemblyInitialize on the InitializeTests system, and moving the MyTest2 classification to another assembly (in case you do not need it to use the InitializeTests at all) or including a TestInitialize formulation to MyTest2.InitializeTests (in case you are looking to add some further initialization certain to SomeOtherTest).

    5. lacking TestFixture attribute

    here is the manner I went in regards to the "Validate a Sudoku Board” problem. however, keep in mind there are assorted the right way to remedy this, so don't worry if your solution has variations and it’s utterly possible there are more productive methods.

    think free to imply your solution within the feedback here or within the original put up, but please be respectful of others’ efforts.

    My strategy

    This one is relatively straight-forward, your simple project is to make sure that the price of any given mobilephone isn’t replicated in the cellphone’s row, column, or “dice”.  The issue is how you go about this.  there's a space-effective way, but requires extra looping, or there's a way that requires only touring any cell one time, however requires added space.

    considering the fact that the puzzle is mounted in dimension (9x9 grid), I’ll select superior algorithmic complexity and use area to dangle the set of all numbers seen for each and every given row, column, and dice.  through the use of 27 units to cling these values (9 for the rows, 9 for the columns, 9 for the cubes), we will simply see if we’ve alread 3X0-202y seen the latest quantity in the given row, column, or dice and immediately declare the puzzle invalid.

    Of direction, we might get much more space-effective and use 27 BitArrays (or one huge one partitioned, etc.), but then we lose the elegance of set common sense.  i love keeping things logically standard after which optimizing for space after deciding on there's a need, so I’d likely choose to use units in my original reply in an assessment, and then point out that if space have been a priority, i would then optimize to BitArray.

    So, right here’s my answer:

    1: public class SudokuBoard 2: three: inner most read 3X0-202only char[,] board; 4: 5: // validate board is a 9x9 array 6: public SudokuBoard(char[,] board) 7: 15: sixteen: public bool Validate() 17: 18: // yes, i may use BitArray for area effectivity, however i like the logical think 19: // of the set and how it returns false on Add() if alread 3X0-202y there. 20: var rows = Enumerable.latitude(1, 9).opt for(i => new HashSet<char>()).ToArray(); 21: var columns = Enumerable.range(1, 9).choose(i => new HashSet<char>()).ToArray(); 22: var cubes = Enumerable.range(1, 9).opt for(i => new HashSet<char>()).ToArray(); 23: 24: // procedure each cell simplest once 25: for (int row = 0; row < 9; ++row) 26: 27: for (int column = 0; column < 9; ++column) 28: 29: var current = board[row, column]; 30: if (char.IsDigit(current)) 31: !cubes[cube].Add(current)) 37: 38: return false; 39: 40: forty one: 42: 43: 44: return proper; forty five: 46:

    note that I’m no longer checking for invalid characters for the sake of brevity, even though we may quite simply do this in the constructor, or in the Validate() formulation itself:

    1: var present = board[row, column]; 2: if (char.IsDigit(existing)) 3: 4: // blah blah blah 5: 6: else if (!char.IsWhiteSpace(present)) 7: 8: return false; 9:

    at last, right here’s an easy driver as an example usage:

    1: public static classification Driver 2: 3: public static void perform() 4: 5: var board = new char[9,9] 6: 7: '5', '3', ' ', ' ', '7', ' ', ' ', ' ', ' ', eight: '6', ' ', ' ', '1', '9', '5', ' ', ' ', ' ', 9: ' ', '9', '8', ' ', ' ', ' ', ' ', '6', ' ', 10: 'eight', ' ', '2', ' ', '6', ' ', ' ', ' ', 'three', eleven: 'four', ' ', ' ', 'eight', ' ', '3', ' ', ' ', '1', 12: '7', ' ', ' ', ' ', '2', ' ', ' ', ' ', '6', 13: ' ', '6', ' ', ' ', ' ', ' ', '2', 'eight', ' ', 14: ' ', ' ', ' ', '4', '1', '9', ' ', ' ', '5', 15: ' ', ' ', ' ', ' ', '8', ' ', ' ', '7', '9', 16: ; 17: 18: var validator = new SudokuBoard(board); 19: 20: Console.WriteLine("The Sudoku board is " + (validator.Validate() ? "legitimate" : "invalid")); 21: 22: abstract

    Hope you had fun with this one!  Of course, I’m sure many available can tweak the answer for efficiency in a number of approaches – but you get the element.

    Have an answer that labored for you however become totally different?  I’d love to hear about it!

    reside tuned next week for the subsequent Little Puzzler.
