  • Why is i-- faster than i++ in loops? [closed]

    - by Afshin Mehrabani
    Possible Duplicate: JavaScript - Are loops really faster in reverse…? I don't know if this question is valid in other languages or not, but I'm asking this specifically for JavaScript. I see in some articles and questions that the fastest loop in JavaScript is something like: for(var i = array.length; i--; ) Also in Sublime Text 2, when you try to write a loop, it suggests: for (var i = Things.length - 1; i >= 0; i--) { Things[i] }; I want to know, why is i-- faster than i++ in loops?

  • Throwing special type of exception to terminate unit test

    - by trendl
    Assume I want to write a unit test to test a particular piece of functionality that is implemented within a method. If I wanted to execute the method completely, I would have to do some extra set up work (mock objects expectations etc.). Instead of doing that I use the following approach: - I set up the expectations I'm interested in verifying and then make the tested method throw a special type of exception (e.g. TerminateTestException). - Further down in the unit test I catch the exception and verify the mock object expectations. It works fine but I'm not sure it is good practice. I do not do this regularly, only in cases where it saves me time and effort. One thing that comes to mind as an argument against using this is that throwing exceptions takes long time so the tests execute slower than if I used a different approach.

  • Start all tab's activities for pre-cache

    - by Pentium10
    I have a TabActivity with three tabs defined. The first tab is light-weight and renders in acceptable time. But the 2nd and 3rd tab, does need a couple of seconds to get visually rendered, after I click them. I would like to launch them, after I've loaded my first tab, in background for pre-cache. Once they are loaded, I can switch quickly between them. So I am wondering how can I launch the 2nd and 3rd tab. They are intents loaded in the view area.

  • PHP Try and Catch for SQL Insert

    - by meme
    I have a page on my website (high traffic) that does an insert on every page load. I am curious of the fastest and safest way to (catch an error) and continue if the system is not able to do the insert into MySQL. Should I use try/catch or die or something else. I want to make sure the insert happens but if for some reason it can't I want the page to continue to load anyway. ... $db = mysql_select_db('mobile', $conn); mysql_query("INSERT INTO redirects SET ua_string = '$ua_string'") or die('Error #10'); mysql_close($conn); ...

  • 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?

  • How to emulate onLowMemory()?

    - by Samuh
    I have put some instructions in onLowMemory() callback and want to test the same. Is there a "direct" way to test onLowMemory function of the application subclass? Or will I have to just overload the phone by starting many apps and doing memory intensive tasks? Thanks.

  • 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?

  • JUnit - assertSame

    - by Michael
    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.

  • Delete from empty table taking forver

    - by Will
    Hello, I have an empty table that previously had a large amount of rows. The table has about 10 columns and indexes on many of them, as well as indexes on multiple columns. DELETE FROM item WHERE 1=1 This takes approximately 40 seconds to complete SELECT * FROM item this takes 4 seconds. The execution plan of SELECT * FROM ITEM shows the following; SQL> select * from midas_item; no rows selected Elapsed: 00:00:04.29 Execution Plan ---------------------------------------------------------- 0 SELECT STATEMENT Optimizer=CHOOSE (Cost=19 Card=123 Bytes=73 80) 1 0 TABLE ACCESS (FULL) OF 'MIDAS_ITEM' (Cost=19 Card=123 Byte s=7380) Statistics ---------------------------------------------------------- 0 recursive calls 0 db block gets 5263 consistent gets 5252 physical reads 0 redo size 1030 bytes sent via SQL*Net to client 372 bytes received via SQL*Net from client 1 SQL*Net roundtrips to/from client 0 sorts (memory) 0 sorts (disk) 0 rows processed any idea why these would be taking so long and how to fix it would be greatly appreciated!!

  • SQL Server 15MM rows, simple COUNT query. 15+ seconds?

    - by john
    We took over a website from another company after a client decided to switch. We have a table that grows by about 25k records a day, and is currently at 15MM records. The table looks something like: id (PK, int, not null) member_id (int, not null) another_id (int, not null) date (datetime, not null) SELECT COUNT(id) FROM tbl can take up to 15 seconds. A simple inner join on 'another_id' takes over 30 seconds. I can't imagine why this is taking so long. Any advice? SQL Server 2005 Express

  • 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...

  • Detecting when Javascript is performing poorly

    - by what-the-crap
    I'm working on a webapp in jquery that, on older machines or machines without much resources, may perform poorly. To get around this I'd like to make a degraded version that disables some of the features, particularly those that rely on large images. How can I tell if my app is running poorly on the user's computer in jquery or javascript in general? I just need a way to call a function that will degrade the app. (especially when the user may run low on system memory) The only way I can think of is for manual user intervention, but the option would add clutter for users that don't need it and users that do need it may not notice it. Thanks!

  • How much faster is C++ than C#?

    - by Trap
    Or is it now the other way around? From what I've heard there are some areas in which C# proves to be faster than C++, but I've never had the guts to test it by myself. Thought any of you could explain these differences in detail or point me to the right place for information on this.

  • 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?

  • Why is casting and comparing in PHP faster than is_*?

    - by tstenner
    While optimizing a function in PHP, I changed if(is_array($obj)) foreach($obj as $key=$value { [snip] } else if(is_object($obj)) foreach($obj as $key=$value { [snip] } to if($obj == (array) $obj) foreach($obj as $key=$value { [snip] } else if($obj == (obj) $obj) foreach($obj as $key=$value { [snip] } After learning about ===, I changed that to if($obj === (array) $obj) foreach($obj as $key=$value { [snip] } else if($obj === (obj) $obj) foreach($obj as $key=$value { [snip] } Changing each test from is_* to casting resulted in a major speedup (30%). I understand that === is faster than == as no coercion has to be done, but why is casting the variable so much faster than calling any of the is_*-functions?

  • 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?
