  • Testing if a list contains another list with Python

    - by None
    How can I test if a list contains another list. Say there was a function called contains: contains([1,2], [-1, 0, 1, 2]) # Returns [2, 3] (contains returns [start, end]) contains([1,3], [-1, 0, 1, 2]) # Returns False contains([1, 2], [[1, 2], 3) # Returns False contains([[1, 2]], [[1, 2], 3]) # Returns [0, 0] Edit: contains([2, 1], [-1, 0, 1, 2]) # Returns False contains([-1, 1, 2], [-1, 0, 1, 2]) # Returns False contains([0, 1, 2], [-1, 0, 1, 2]) # Returns [1, 3]

  • Unit Testing XML independent of physical XML file

    - by RAbraham
    Hi, My question is: In JUnit, How do I setup xml data for my System Under Test(SUT) without making the SUT read from an XML file physically stored on the file system Background: I am given a XML file which contains rules for creation of an invoice. My job is to convert these rules from XMl to Java Objects e.g. If there is a tag as below in my XML file which indicates that after a period of 30 days, the transaction cannot be invoiced <ExpirationDay>30</ExpirationDay> this converts to a Java class , say ExpirationDateInvoicingRule I have a class InvoiceConfiguration which should take the XML file and create the *InvoicingRule objects. I am thinking of using StAX to parse the XML document within InvoiceConfiguration Problem: I want to unit test InvoiceConfiguration. But I dont want InvoiceConfiguration to read from an xml file physically on the file system . I want my unit test to be independent of any physical stored xml file. I want to create a xml representation in memory. But a StAX parser only takes FileReader( or I can play with the File Object)

  • OCUnit testing an embedded framework

    - by d11wtq
    I've added a Unit Test target to my Xcode project but it fails to find my framework when it builds, saying: Test.octest could not be loaded because a link error occurred. It is likely that dyld cannot locate a framework framework or library that the the test bundle was linked against, possibly because the framework or library had an incorrect install path at link time. My framework (the main project target) is designed to be embedded and so has an install path of @executable_path/../Frameworks. I've marked the framework as a direct dependency of the test target and I've added it to the "Link Binary with Libraries" build phase. Additionally I've add a first step (after it's built the dependency) of "Copy Files" which simply copies the framework to the unit test bundle's Frameworks directory. Anyone got any experience on this? I'm not sure what I've missed.

  • ocunit testing on iPhone

    - by Magnus Poromaa
    Hi I am trying to get ocunit working in my project from XCode. Since I also need to debug in the unit tests I am using a script that automates the setup (see below). I just include it in the project under resources and change the name to the .ocunit file I want it to run. The problem I get is that it cant find the bundle file and therefore exists with an error. Can anyone who has a clue about XCode and objective-c take a look at it and tell me what is wrong. Also how am I supposed to produce the .ocunit file that I need to run. By setting up a new unit test target for the iPhone and add tests to it or? Hope someone has a clue since I just started ny iPhone development and need to get it up and running quickly Apple Script -- The only customized value we need is the name of the test bundle tell me to activate tell application "Xcode" activate set thisProject to project of active project document tell thisProject set testBundleName to name of active target set unitTestExecutable to make new executable at end of executables set name of unitTestExecutable to testBundleName set path of unitTestExecutable to "/Applications/TextEdit.app" tell unitTestExecutable -- Add a "-SenTest All" argument make new launch argument with properties {active:true, name:"-SenTest All"} -- Add the magic set injectValue to "$(BUILT_PRODUCTS_DIR)/" & testBundleName & ".octest" make new environment variable with properties {active:true, name:"XCInjectBundle", value:injectValue} make new environment variable with properties {active:true, name:"XCInjectBundleInto", value:"/Applications/TextEdit.app/Contents/MacOS/TextEdit"} make new environment variable with properties {active:true, name:"DYLD_INSERT_LIBRARIES", value:"$(DEVELOPER_LIBRARY_DIR)/PrivateFrameworks/DevToolsBundleInjection.framework/DevToolsBundleInjection"} make new environment variable with properties {active:true, name:"DYLD_FALLBACK_FRAMEWORK_PATH", value:"$(DEVELOPER_LIBRARY_DIR)/Frameworks"} end tell end tell end tell Cheers Magnus

  • iphone OCMockObject and unit-testing a class that inherits from NSURLConnection

    - by Justin Galzic
    I want to unit test the custom init method of a class that inherits from NSURLConnection -- how would I do this if the init of my testable class invokes NSURLConnection's initWithRequest? I'm using OCMock and normally, I can mock objects that are contained within my test class. For this inheritance scenario, what's the best approach to do this? - (void)testInit { id urlRequest = [OCMockObject mockForClass:[NSURLRequest class]]; MyURLConnectionWrapper *conn = [[MyURLConnectionWrapper alloc] initWithRequest:urlRequest delegate:self someData:extraneousData]; } My class is implemented like this: @interface MyURLConnectionWrapper : NSURLConnection { } - (id)initWithRequest:(NSURLRequest *)request delegate:(id)delegate someData:(NSString *)fooData @end @implementation MyURLConnectionWrapper - (id)initWithRequest:(NSURLRequest *)request delegate:(id)delegate someData:(NSString *)fooData { if (self = [super initWithRequest:request delegate:delegate]) { // do some additional work here } return self; } Here's the error I get: OCMockObject[NSURLRequest]: unexpected method invoked: _CFURLRequest

If I generate my own views and add a few attributes to my devise-model, they won´t be save in the database. I read the docu at github, but don´t really checked it. mattherick

  • Testing Rails Metal/Rack with RSpec?

    - by Matt Darby
    Say I have a Metal class named Preview. How do I test it with RSpec? When I try: require 'spec_helper' describe Preview do it "should return the posted content" do post "/preview", :content => "*title*" response.body.should == "*title*" end end I get: undefined method `post' for #<ActiveSupport::TestCase::Subclass_1:0x1058b3098> It seems that RSpec doesn't load up the :post method if the test isn't explicitly for a Controller. I've tried specifying :type => :controller to no avail.

  • Testing warnings with doctest

    - by Eli Courtwright
    I'd like to use doctests to test the presence of certain warnings. For example, suppose I have the following module: from warnings import warn class Foo(object): """ Instantiating Foo always gives a warning: >>> foo = Foo() testdocs.py:14: UserWarning: Boo! warn("Boo!", UserWarning) >>> """ def __init__(self): warn("Boo!", UserWarning) If I run python -m doctest testdocs.py to run the doctest in my class and make sure that the warning is printed, I get: testdocs.py:14: UserWarning: Boo! warn("Boo!", UserWarning) ********************************************************************** File "testdocs.py", line 7, in testdocs.Foo Failed example: foo = Foo() Expected: testdocs.py:14: UserWarning: Boo! warn("Boo!", UserWarning) Got nothing ********************************************************************** 1 items had failures: 1 of 1 in testdocs.Foo ***Test Failed*** 1 failures. It looks like the warning is getting printed but not captured or noticed by doctest. I'm guessing that this is because warnings are printed to sys.stderr instead of sys.stdout. But this happens even when I say sys.stderr = sys.stdout at the end of my module. So is there any way to use doctests to test for warnings? I can find no mention of this one way or the other in the documentation or in my Google searching.

  • Testing a Doctrine2 Entity with assertEquals results in fatal out-of-memory error

    - by Matt
    I have a PHPUnit test that's using a Doctrine2 custom repository and Doctrine Fixtures. I wanted to test that a query gave me back an expected entity from my fixture. But when I try $this->assertEquals($expectedEntity, $result);, I get Fatal error: out of memory. I'm guessing it is recursing into all the relations and the entity manager and whatnot. Is there a good way to test this equality? Should I just assertEquals on the IDs of the entities?

  • Testing background audio in the simulator

    - by Cactuar
    I'm experimenting with the new background audio service in iPhone OS 4.0 but I can't get it to work in the simulator. According to this page: iPhone Application Programming Guide: Executing Code in the Background it seems that all I have to do is add the a UIBackgroundModes key with an array containing audio to my Info.plist file and the audio my application plays should automatically continue when I switch to another app. I have done this but the audio still pauses as I switch to another app, when I switch back it continues where it left off. This is the code I'm using to play the sound: NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/audio.mp3", [[NSBundle mainBundle] resourcePath]]]; NSError *error; audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error]; audioPlayer.numberOfLoops = -1; if (audioPlayer == nil) NSLog(@"%@", [error userInfo]); else [audioPlayer play]; Has anyone gotten this to work? Could it be that it would work on an actual device and it's just a problem with the simulator? I'm a bit hesitant to install 4.0 on my phone since I've heard it's still very buggy. Wish I had another device to use only for development.

  • C# - Getting a RawFraction Performance Counter to show a persistant value

    - by jacko
    I've created a performance counter that shows a fraction of an incremeted value (RawFraction type) over a base value (RawBase). Unfortunately, when monitoring this value, it only shows the percentage when one of the counters is incremented. At all other times it it is sampled, it shows 0. Is there some way to tell the counter to hold onto the last value until the next time it needs to recalculate the fraction?

  • mysql enum performance: is enum slower than INT

    Hi, Is it better to have a field status enum('active', 'hidden', 'deleted') OR status tinyint(3) with a lookup table. Assume that status can take only one value at a time. In particular, I am interested in knowing, are operations on enum significantly slower than or as fast as operations on int ? There is a related question on SO Mysql: enum confusion but i) It does not discuss performance at all ii) There is very little explanation on WHY one approach is better than the other. regards, JP

  • WPF Application Typing in Custom TextBox CPU Jumping from 3 to 80 percent

    - by azamsharp
    I have created a RichTextBox called SharpTextBox which indicates and limits the number of characters that can be typed in it. The implementation is shown in the following link: http://www.highoncoding.com/Articles/673_Creating_SharpRichTextBox_for_Live_Character_Count_in_WPF.aspx Anyway when I start typing in the TextBox it goes from 3% to 78%. The TextBox updates the Label control which shows the number of characters remaining for the count. How can I increase the performance of the textbox? UPDATE: I read there seems to be some problem with the TextRange.Text property which kills performance.

  • Performance of CSS Transitions vs. JS animation packages

    - by desau
    I'm wondering - is there any difference in performance of using CSS Transitions vs. any of the various JS animation libraries? (scriptaculous, scripty2, jsAnim, MooTools, $fx, etc, etc). I've tried various tests in Safari / Google Chrome, and I don't actually see any difference -- I thought that CSS Transitions were supposed to be hardware accelerated.

  • My linux server takes more than an hour to boot. Suggestions?

    - by jamieb
    I am building a CentOS 5.4 system that boots off a compact flash card using a card reader that emulates an IDE drive. It literally takes about an hour to boot. The ultra-slow part occurs when Grub is loading the kernel. Once that's done, the rest of the boot process only takes about a minute to get to a login prompt. Does anyone have any suggestions? I suspect that it may have to do with UDMA. Everything IDE-related in my BIOS seems to checkout. The read performance hdparm is telling me 1.77 MB/s. Ouch! (But even at that rate, it still shouldn't take an hour to decompress and load the kernel) [root@server ~]# hdparm -tT /dev/hdc /dev/hdc: Timing cached reads: 2444 MB in 2.00 seconds = 1222.04 MB/sec Timing buffered disk reads: 6 MB in 3.39 seconds = 1.77 MB/sec Trying to enable DMA is a no-go though: [root@server ~]# hdparm -d1 /dev/hdc /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) Here's some command outputs that might help: System [root@server ~]# uname -a Linux server.localdomain 2.6.18-164.el5xen #1 SMP Thu Sep 3 04:47:32 EDT 2009 i686 i686 i386 GNU/Linux PCI info: [root@server ~]# lspci -v 00:00.0 Host bridge: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub (rev 02) Subsystem: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub Flags: bus master, fast devsel, latency 0 Capabilities: [e0] Vendor Specific Information 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) (prog-if 00 [VGA controller]) Subsystem: Intel Corporation 82945G/GZ Integrated Graphics Controller Flags: bus master, fast devsel, latency 0, IRQ 10 Memory at fdf00000 (32-bit, non-prefetchable) [size=512K] I/O ports at ff00 [size=8] Memory at d0000000 (32-bit, prefetchable) [size=256M] Memory at fdf80000 (32-bit, non-prefetchable) [size=256K] Capabilities: [90] Message Signalled Interrupts: 64bit- Queue=0/0 Enable- Capabilities: [d0] Power Management version 2 00:1d.0 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 Flags: bus master, medium devsel, latency 0, IRQ 16 I/O ports at fe00 [size=32] 00:1d.1 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 Flags: bus master, medium devsel, latency 0, IRQ 17 I/O ports at fd00 [size=32] 00:1d.2 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 Flags: bus master, medium devsel, latency 0, IRQ 18 I/O ports at fc00 [size=32] 00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 Flags: bus master, medium devsel, latency 0, IRQ 19 I/O ports at fb00 [size=32] 00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 01) (prog-if 20 [EHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller Flags: bus master, medium devsel, latency 0, IRQ 16 Memory at fdfff000 (32-bit, non-prefetchable) [size=1K] Capabilities: [50] Power Management version 2 Capabilities: [58] Debug port 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) (prog-if 01 [Subtractive decode]) Flags: bus master, fast devsel, latency 0 Bus: primary=00, secondary=01, subordinate=01, sec-latency=32 I/O behind bridge: 0000d000-0000dfff Memory behind bridge: fde00000-fdefffff Prefetchable memory behind bridge: 00000000fdd00000-00000000fdd00000 Capabilities: [50] #0d [0000] 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) Subsystem: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge Flags: bus master, medium devsel, latency 0 Capabilities: [e0] Vendor Specific Information 00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller (rev 01) (prog-if 80 [Master]) Subsystem: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller Flags: bus master, 66MHz, medium devsel, latency 0, IRQ 17 I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at f800 [size=16] Capabilities: [70] Power Management version 2 00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01) Subsystem: Intel Corporation 82801G (ICH7 Family) SMBus Controller Flags: medium devsel, IRQ 17 I/O ports at 0500 [size=32] 01:04.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
