  • Cannot execute newly created TestMethod in VS2010

    - by FrontSvin
    When I try to run a new TestMethod on an existing TestClass in Visual Studio 2010 (by right-clicking on the method name and choosing Run Tests) the test method does not execute. After a restart of VS, the problem has gone. Am I missing some refresh thing, or is right-clicking even the correct way of executing a single test method?

  • Ways to Unit Test Oauth for different services in ruby?

    - by viatropos
    Are there any best practices in writing unit tests when 90% of the time I'm building the Oauth connecting class, I need to actually be logging into the remote service? I am building a rubygem that logs in to Twitter/Google/MySpace, etc., and the hardest part is making sure I have the settings right for that particular provider, and I would like to write tests for that. Is there a recommended way to do that? If I did mocks or stubs, I'd still have to spend that 90% of the time figuring out how to use the service, and would end up writing tests after the fact instead of before...

  • Why Create Mock Objects?

    - by Chris
    During a recent interview I was asked why one would want to create mock objects. My answer went something like, "Take a database--if you're writing test code, you may not want that test hooked up live to the production database where actual operations will be performed." Judging by response, my answer clearly was not what the interviewer was looking for. What's a better answer?

  • How do I inherit abstract unit tests in Ruby?

    - by Graeme Moss
    I have two unit tests that should share a lot of common tests with slightly different setup methods. If I write something like class Abstract < Test::Unit::TestCase def setup @field = create end def test_1 ... end end class Concrete1 < Abstract def create SomeClass1.new end end class Concrete2 < Abstract def create SomeClass2.new end end then Concrete1 does not seem to inherit the tests from Abstract. Or at least I cannot get them to run in eclipse. If I choose "Run all TestCases" for the file that contains Concrete1 then Abstract is run even though I do not want it to be. If I specify Concrete1 then it does not run any tests at all! If I specify test_1 in Concrete1 then it complains it cannot find it ("uncaught throw :invalid_test (ArgumentError)"). I'm new to Ruby. What am I missing here?

  • Using Moq to Validate Separate Invocations with Distinct Arguments

    - by Thermite
    I'm trying to validate the values of arguments passed to subsequent mocked method invocations (of the same method), but cannot figure out a valid approach. A generic example follows: public class Foo { [Dependency] public Bar SomeBar { get; set; } public void SomeMethod() { this.SomeBar.SomeOtherMethod("baz"); this.SomeBar.SomeOtherMethod("bag"); } } public class Bar { public void SomeOtherMethod(string input) { } } public class MoqTest { [TestMethod] public void RunTest() { Mock<Bar> mock = new Mock<Bar>(); Foo f = new Foo(); mock.Setup(m => m.SomeOtherMethod(It.Is<string>("baz"))); mock.Setup(m => m.SomeOtherMethod(It.Is<string>("bag"))); // this of course overrides the first call f.SomeMethod(); mock.VerifyAll(); } } Using a Function in the Setup might be an option, but then it seems I'd be reduced to some sort of global variable to know which argument/iteration I'm verifying. Maybe I'm overlooking the obvious within the Moq framework?

  • JUnit - assertSame

    Can someone tell me why assertSame() do fail when I use values 127? import static org.junit.Assert.*; ... @Test public void StationTest1() { .. assertSame(4, 4); // OK assertSame(10, 10); // OK assertSame(100, 100); // OK assertSame(127, 127); // OK assertSame(128, 128); // raises an junit.framework.AssertionFailedError! assertSame(((int) 128),((int) 128)); // also junit.framework.AssertionFailedError! } I'm using JUnit 4.8.1.

  • Does it make sense to test ui components seperately?

    - by Bless Yahu
    I'm working on a webform that has about 15 user controls, separated by context (comments, locations, members/leaders, etc).   If each control can render individually (using real or test data), does it make sense to have a seperate "functional" test page to test them in isolation or is there a better way?

  • How to use __LINE__ in a string

    - by John
    Just using it as a method parameter is fine but what about an easy way to use it in strings? For instance say I have this: 11 void myTest() 12 { 13 if(!testCondition) 14 logError("testcondition failed"); 15 } And I want the output to be: "myTest line 14: testcondition failed" How can I write logError? Does it have to be some monstrosity of a macro?

  • How specific do I get in BDD scenarios?

    - by CodeSpelunker
    Take two different ways of stating the same behavior. Option A: Given a customer has 50 items in their shopping cart When they check out Then they will receive a 10% discount on their order Option B: Given a customer has a high volume of items in their shopping cart When they check out Then they will receive a high volume discount on their order The former is far more specific. If someone has some question about exactly when a customer gets a high volume discount or how much to give them, reading this scenario makes it very clear. Serving the purposes of documenting the behavior, it's about as specific as it can be, although any change in those values will require changing the scenario. The second is more generalized and doesn't have the clarity of the first. Automating it would require incorporating the values "50" and "10" in the step implementations. On the other hand, the scenario captures the core business need: a high volume customer gets a discount. If we later decide to use "40" and "15", the scenario doesn't have to change because the core business need hasn't really changed (though the step implementation would). Also, the term "high volume customer" communicates something about why we're giving them the discount. So, which is better? Rather, under what circumstances should I favor the former or the latter?

  • Is it possible to copy recordings off of a DVR box hard drive?

    - by bdr9
    My cable TV company gives me a Cisco Explorer 8640HDC DVR box that can record shows from TV. I know that it contains a hard drive to save the shows on. What format and file system are used to store the videos on the hard drive? I have looked at the documentation for this DVR box and there is no technical information about the manner in which recordings are stored. Is it possible to connect the hard drive to a computer and extract the recordings from it?

  • HP SmartArray P400: How to repair failed logical drive?

    - by TegtmeierDE
    I have a HP Server with SmartArray P400 controller (incl. 256 MB Cache/Battery Backup) with a logicaldrive with replaced failed physicaldrive that does not rebuild. This is how it looked when I detected the error: ~# /usr/sbin/hpacucli ctrl slot=0 show config Smart Array P400 in Slot 0 (Embedded) (sn: XXXX) array A (SATA, Unused Space: 0 MB) logicaldrive 1 (698.6 GB, RAID 1, OK) physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SATA, 750 GB, OK) physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SATA, 750 GB, OK) array B (SATA, Unused Space: 0 MB) logicaldrive 2 (2.7 TB, RAID 5, Failed) physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SATA, 750 GB, OK) physicaldrive 1I:1:4 (port 1I:box 1:bay 4, SATA, 750 GB, OK) physicaldrive 2I:1:5 (port 2I:box 1:bay 5, SATA, 750 GB, OK) physicaldrive 2I:1:6 (port 2I:box 1:bay 6, SATA, 750 GB, Failed) physicaldrive 2I:1:7 (port 2I:box 1:bay 7, SATA, 750 GB, OK) unassigned physicaldrive 2I:1:8 (port 2I:box 1:bay 8, SATA, 750 GB, OK) ~# I thought that I had drive 2I:1:8 configured as a spare for Array A and Array B, but it seems this was not the case :-(. I noticed the problem due to I/O errors on the host, even if only 1 physicaldrive of the RAID5 is failed. Does someone know why this could happen? The logicaldrive should go into "Degraded" mode but still be fully accessible from the host os!? I first tried to add the unassigned drive 2I:1:8 as a spare to logicaldrive 2, but this was not possible: ~# /usr/sbin/hpacucli ctrl slot=0 array B add spares=2I:1:8 Error: This operation is not supported with the current configuration. Use the "show" command on devices to show additional details about the configuration. ~# Interestingly it is possible to add the unassigned drive to the first array without problems. I thought maybe the controller put the array into "failed" state due to the missing spare and protects failed arrays from modification. So I tried was to reenable the logicaldrive (to add the spare afterwards): ~# /usr/sbin/hpacucli ctrl slot=0 ld 2 modify reenable Warning: Any previously existing data on the logical drive may not be valid or recoverable. Continue? (y/n) y Error: This operation is not supported with the current configuration. Use the "show" command on devices to show additional details about the configuration. ~# But as you can see, re-enabling the logicaldrive this was not possible. Now I replaced the failed drive by hotswapping it with the unassigned drive. The status now looks like this: ~# /usr/sbin/hpacucli ctrl slot=0 show config Smart Array P400 in Slot 0 (Embedded) (sn: XXXX) array A (SATA, Unused Space: 0 MB) logicaldrive 1 (698.6 GB, RAID 1, OK) physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SATA, 750 GB, OK) physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SATA, 750 GB, OK) array B (SATA, Unused Space: 0 MB) logicaldrive 2 (2.7 TB, RAID 5, Failed) physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SATA, 750 GB, OK) physicaldrive 1I:1:4 (port 1I:box 1:bay 4, SATA, 750 GB, OK) physicaldrive 2I:1:5 (port 2I:box 1:bay 5, SATA, 750 GB, OK) physicaldrive 2I:1:6 (port 2I:box 1:bay 6, SATA, 750 GB, OK) physicaldrive 2I:1:7 (port 2I:box 1:bay 7, SATA, 750 GB, OK) ~# The logical drive is still not accessible. Why is it not rebuilding? What can I do? FYI, this is the configuration of my controller: ~# /usr/sbin/hpacucli ctrl slot=0 show Smart Array P400 in Slot 0 (Embedded) Bus Interface: PCI Slot: 0 Serial Number: XXXX Cache Serial Number: XXXX RAID 6 (ADG) Status: Enabled Controller Status: OK Chassis Slot: Hardware Revision: Rev E Firmware Version: 5.22 Rebuild Priority: Medium Expand Priority: Medium Surface Scan Delay: 15 secs Surface Analysis Inconsistency Notification: Disabled Raid1 Write Buffering: Disabled Post Prompt Timeout: 0 secs Cache Board Present: True Cache Status: OK Accelerator Ratio: 25% Read / 75% Write Drive Write Cache: Disabled Total Cache Size: 256 MB No-Battery Write Cache: Disabled Cache Backup Power Source: Batteries Battery/Capacitor Count: 1 Battery/Capacitor Status: OK SATA NCQ Supported: True ~# Thanks for you help in advance.

  • Floats will not align, stay staggered, can't find a solution?

    - by Sarah Proper
    What I am trying to do is build a multi column layout. The main two sections are divided 2/3 to 1/3 and inside the 2/3 column is divided 2/3 1/3 as well. My problem is that my floats will not align nicely with each other, choosing instead to stagger like stairs. I have tried declaring the widths smaller, floating them individually, including in the float sections display:block,inline, or inline-block and nothing seems to be working.

  • How to fix White Screen of Death after updating iTunes?

    - by cust0s
    The other night I updated my iTunes to the latest version (through Software Update) when I came to turn on my computer I was greeted with the dreaded white screen of death. I use an early 2008 iMac 24". I've tried the basic things, unplugging/turning off accessories, trying to boot from the install disk, reseting pram, etc, etc. Still no luck and no change what-so-ever. All I've been able to ascertain that my keyboard still works (by ejecting). I should point out that I did recently replace my Hard drive with a Western Digital Black 500GB (though the computer is well out of warrenty) and I'm a little concerned that the problem could be the screen.

  • What are those white circles on the desktop in Gnome 3?

    - by monk
    I have Fedora 20 with GNOME 3.10.2. On the desktop background (i.e. where the wallpaper is), there are five small white circles centered at the very bottom of the screen. The first is filled, the others are not. I can click those circles, thereby changing which one is filled, like a radio button. I cannot for the life of me figure out what those circles are supposed to do, and it's starting to drive me crazy. Clicking and thus changing which circle is filled does nothing I can perceive, and there seems to be no configuration option anywhere that has anything to do with them. What are those things? Is there any way to get rid of them? Edit: I made a screenshot of my desktop with no programs running. You can see the dot/circle thingies at the bottom.

  • Jquery only works the first time

    - by Tripping
    I am trying to teach myself general web development skills. I am trying to create a image upload with preview functionality using HTML5 FileAPI. Till now, I have created a file input which shows the preview of image when selected. Html mark up is below: <div> <!-- Photos --> <fieldset> <legend>PropertyPhotos</legend> <div class="upload-box" id="upload-box-1"> <div class="preview-box"> <img alt="Field for image cutting" id="preview_1" src="@Url.Content("~/Content/empty.png")" /> </div> <div> @Html.FileFor(model => model.File1) @Html.ValidationMessageFor(model => model.File1) </div> </div> <div class="upload-box" id="upload-box-2"> <div class="preview-box"> <img alt="Field for image cutting" id="preview_2" src="@Url.Content("~/Content/empty.png")" /> </div> <div> @Html.FileFor(model => model.File2) @Html.ValidationMessageFor(model => model.File2) </div> </div> <div class="upload-box" id="upload-box-3"> <div class="preview-box"> <img alt="Field for image cutting" id="preview_3" src="@Url.Content("~/Content/empty.png")" /> </div> <div> @Html.FileFor(model => model.File3) @Html.ValidationMessageFor(model => model.File3) </div> </div> </fieldset> </div> The Jquery to show preview and then display the next "upload-box" is as follows: <script type="text/javascript"> $(document).ready(function () { // show first box $("#upload-box-1").fadeIn(); //Get current & next step index var stepNum = $('div.upload-box').attr('id').replace(/[^\d]/g, ''); var nextNum = parseInt(stepNum)+1; //Get the preview image tag var preview = $('#preview_'+stepNum); //Load preview on file tag change and display second upload-box $('#File'+stepNum).change(function (evt) { var f = evt.target.files[0]; var reader = new FileReader(); if (!f.type.match('image.*')) { alert("The selected file does not appear to be an image."); return; } reader.onload = function (e) { preview.attr('src', e.target.result); }; reader.readAsDataURL(f); //Show next upload-box $("#upload-box-" + nextNum).fadeIn(); }); }); </script> However, this code only first for the first time ... i.e. on selecting a file - It shows a preview and then shows the next "upload-box". However, when I browse using the second file it doesn't show any preview. From what I have ready, I need to close the Jquery function so that it can be initialised again but I am not sure how to do that. Any help will be grateful.

  • How to fetch only the sprites in the player's range of motion for collision testing? (2D, axis aligned sprites)

    - by Twodordan
    I am working on a 2D sprite game for educational purposes. (In case you want to know, it uses WebGl and Javascript) I've implemented movement using the Euler method (and delta time) to keep things simple. Now I'm trying to tackle collisions. The way I wrote things, my game only has rectangular sprites (axis aligned, never rotated) of various/variable sizes. So I need to figure out what I hit and which side of the target sprite I hit (and I'm probably going to use these intersection tests). The old fashioned method seems to be to use tile based grids, to target only a few tiles at a time, but that sounds silly and impractical for my game. (Splitting the whole level into blocks, having each sprite's bounding box fit multiple blocks I might abide. But if the sprites change size and move around, you have to keep changing which tiles they belong to, every frame, it doesn't sound right.) In Flash you can test collision under one point, but it's not efficient to iterate through all the elements on stage each frame. (hence why people use the tile method). Bottom line is, I'm trying to figure out how to test only the elements within the player's range of motion. (I know how to get the range of motion, I have a good idea of how to write a collisionCheck(playerSprite, targetSprite) function. But how do I know which sprites are currently in the player's vicinity to fetch only them?) Please discuss. Cheers!

  • What is a technique for 2D ray-box intersection that is suitable for old console hardware?

    - by DJCouchyCouch
    I'm working on a Sega Genesis homebrew game (it has a 7mhz 68000 CPU). I'm looking for a way to find the intersection between a particle sprite and a background tile. Particles are represented as a point with a movement vector. Background tiles are 8 x 8 pixels, with an (X,Y) position that is always located at a multiple of 8. So, really, I need to find the intersection point for a ray-box collision; I need to find out where along the edge of the tile the ray/particle hits. I have these two hard constraints: I'm working with pixel locations (integers). Floating point is too expensive. It doesn't have to be super exact, just close enough. Multiplications, divisions, dot products, et cetera, are incredibly expensive and are to be avoided. So I'm looking for an efficient algorithm that would fit those constraints. Any ideas? I'm writing it in C, so that would work, but assembly should be good as well.
