• Running PHP Zend Test in Eclipse

  - by Carlos Eiroa

  Is it possible to run PHP Zend test cases (those that extend Zend_Test_PHPUnit_ControllerTestCase, etc.) through Eclipse PDT? I would like to be able to run them in a similar fashion as you run JUnit tests in Eclipse, by right-clicking the test file and selecting "Run as a JUnit test case." I'd love to see the green or red bar instead of having to go to the command line :). Thanks in advance.

• Increasing speed of webservice - howto

  - by Koran

  Hi, Our client-server product has the protocol between them as XML over HTTP. Here, the client asks a GET/POST query to the web server and the server responds with XML. The server is written using django. The server has to be on the web because there are many clients across the world using this. The server code uses extensive memoization and also there is very less db queries - most queries dont have any db queries, some of them has max 1. The biggest problem is the speed. Every query takes close to 5 seconds for the reply. The data replied is also very less - in the range of 4-6 Kb. What are the mechanisms to improve speed of the web service? Is this the usual way of writing a client-server? Are there other technologies and are we missing out on it? Thank you K

• 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

• Action works, but test doesn't (Shoulda)

  - by trobrock

  I am trying to test my update action in Rails with this: context "on PUT to :update" do setup do @countdown = Factory(:countdown) @new_countdown = Factory.stub(:countdown) put :update, :id => @countdown.id, :name => @new_countdown.name, :end => @new_countdown.end end should_respond_with :redirect should_redirect_to("the countdowns view") { countdown_url(assigns(:countdown)) } should_assign_to :countdown should_set_the_flash_to /updated/i should "save :countdown with new attributes" do @countdown = Countdown.find(@countdown.id) assert_equal @new_countdown.name, @countdown.name assert_equal 0, (@new_countdown.end - @countdown.end).to_i end end When I actually go through the updating process using the scaffold that was built it updates the record fine, but the tests give me this error: 1) Failure: test: on PUT to :update should save :countdown with new attributes.

• During Spring unit test, data written to db but test not seeing the data

  - by richever

  I wrote a test case that extends AbstractTransactionalJUnit4SpringContextTests. The single test case I've written creates an instance of class User and attempts to write it to the database using Hibernate. The test code then uses SimpleJdbcTemplate to execute a simple select count(*) from the user table to determine if the user was persisted to the database or not. The test always fails though. I was suspect because in the Spring controller I wrote, the ability to save an instance of User to the db is successful. So I added the Rollback annotation to the unit test and sure enough, the data is written to the database since I can even see it in the appropriate table -- the transaction isn't rolled back when the test case is finished. Here's my test case: @ContextConfiguration(locations = { "classpath:context-daos.xml", "classpath:context-dataSource.xml", "classpath:context-hibernate.xml"}) public class UserDaoTest extends AbstractTransactionalJUnit4SpringContextTests { @Autowired private UserDao userDao; @Test @Rollback(false) public void teseCreateUser() { try { UserModel user = randomUser(); String username = user.getUserName(); long id = userDao.create(user); String query = "select count(*) from public.usr where usr_name = '%s'"; long count = simpleJdbcTemplate.queryForLong(String.format(query, username)); Assert.assertEquals("User with username should be in the db", 1, count); } catch (Exception e) { e.printStackTrace(); Assert.assertNull("testCreateUser: " + e.getMessage()); } } } I think I was remiss by not adding the configuration files. context-hibernate.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd> <bean id="namingStrategy" class="org.springframework.beans.factory.config.FieldRetrievingFactoryBean"> <property name="staticField"> <value>org.hibernate.cfg.ImprovedNamingStrategy.INSTANCE</value> </property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean" destroy-method="destroy" scope="singleton"> <property name="namingStrategy"> <ref bean="namingStrategy"/> </property> <property name="dataSource" ref="dataSource"/> <property name="mappingResources"> <list> <value>com/company/model/usr.hbm.xml</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.use_sql_comments">true</prop> <prop key="hibernate.query.substitutions">yes 'Y', no 'N'</prop> <prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop> <prop key="hibernate.cache.use_query_cache">true</prop> <prop key="hibernate.cache.use_minimal_puts">false</prop> <prop key="hibernate.cache.use_second_level_cache">true</prop> <prop key="hibernate.current_session_context_class">thread</prop> </props> </property> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"/> <property name="nestedTransactionAllowed" value="false" /> </bean> <bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor"> <property name="transactionManager"> <ref local="transactionManager"/> </property> <property name="transactionAttributes"> <props> <prop key="create">PROPAGATION_REQUIRED</prop> <prop key="delete">PROPAGATION_REQUIRED</prop> <prop key="update">PROPAGATION_REQUIRED</prop> <prop key="*">PROPAGATION_SUPPORTS,readOnly</prop> </props> </property> </bean> </beans> context-dataSource.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> <property name="driverClass" value="org.postgresql.Driver" /> <property name="jdbcUrl" value="jdbc\:postgresql\://localhost:5432/company_dev" /> <property name="user" value="postgres" /> <property name="password" value="postgres" /> </bean> </beans> context-daos.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean id="extendedFinderNamingStrategy" class="com.company.dao.finder.impl.ExtendedFinderNamingStrategy"/> <bean id="finderIntroductionAdvisor" class="com.company.dao.finder.impl.FinderIntroductionAdvisor"/> <bean id="abstractDaoTarget" class="com.company.dao.impl.GenericDaoHibernateImpl" abstract="true" depends-on="sessionFactory"> <property name="sessionFactory"> <ref bean="sessionFactory"/> </property> <property name="namingStrategy"> <ref bean="extendedFinderNamingStrategy"/> </property> </bean> <bean id="abstractDao" class="org.springframework.aop.framework.ProxyFactoryBean" abstract="true"> <property name="interceptorNames"> <list> <value>transactionInterceptor</value> <value>finderIntroductionAdvisor</value> </list> </property> </bean> <bean id="userDao" parent="abstractDao"> <property name="proxyInterfaces"> <value>com.company.dao.UserDao</value> </property> <property name="target"> <bean parent="abstractDaoTarget"> <constructor-arg> <value>com.company.model.UserModel</value> </constructor-arg> </bean> </property> </bean> </beans> Some of this I've inherited from someone else.

• What is faster with PictureBox? Many small redraws or complete redraw.

  - by kornelijepetak

  I have a PictureBox (WinMobile 6 WinForm) on which I draw some images. There is a background image that goes in the background and it does not change. However objects that are drawn on the picturebox are moving during the application so I need to refresh the background. Since items that are redrawn fill from 50% to 80% of the surface, the question is which of the two is faster: 1) Redraw only parts of the background image that have been changed (previous+next location of the moving object). 2) Redraw complete background and then draw all the objects in their current position. Now, the reason for asking is because I am not sure how much of processor power is needed for a single drawImage operation and what are the time consuming factors. I am aware if there is almost complete coverage of the background, it would be stupid to redraw portions of it, because by drawing portions I will have drawn the complete picture. But since sometimes only half of the image had changed (some objects remained in their old position), it may (perhaps) be benefitial to redraw only those regions. But I need your insight on this... Thanks.

• CakePHP. How can i make a model test in a table with another primary key?

  - by Marcelo

  I have this table CREATE TABLE myexamples.problems ( id INT, name VARCHAR(45) NULL , pk_id INT AUTO_INCREMENT PRIMARY KEY ); But when I try test a model in cakephp, it fails because the table has two autoincrement attributes. The following query CREATE TABLE `test_suite_problems` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(45) DEFAULT NULL, `pk_id` int(11) NOT NULL AUTO_INCREMENT, PRIMARY KEY (`pk_id`) ) DEFAULT CHARSET=latin1, COLLATE=latin1_swedish_ci, ENGINE=InnoDB; raise this error: "1075: Incorrect table definition; there can be only one auto column and it must be defined as a key" I have in the model class <?php class Problem extends AppModel { var $name = 'Problem'; var $displayField = 'name'; var $primaryKey='problems'; } ?> But I don't know how to make the field ID not having an autoincrement attribute, and I can't change the table structure.

• How do you organise your MVC controller tests?

  - by Andrew Bullock

  I'm looking for tidy suggestions on how people organise their controller tests. For example, take the "add" functionality of my "Address" controller, [AcceptVerbs(HttpVerbs.Get)] public ActionResult Add() { var editAddress = new DTOEditAddress(); editAddress.Address = new Address(); editAddress.Countries = countryService.GetCountries(); return View("Add", editAddress); } [RequireRole(Role = Role.Write)] [AcceptVerbs(HttpVerbs.Post)] public ActionResult Add(FormCollection form) { // save code here } I might have a fixture called "when_adding_an_address", however there are two actions i need to test under this title... I don't want to call both actions in my Act() method in my fixture, so I divide the fixture in half, but then how do I name it? "When_adding_an_address_GET" and "When_adding_an_address_POST"? things just seems to be getting messy, quickly. Also, how do you deal with stateless/setupless assertions for controllers, and how do you arrange these wrt the above? for example: [Test] public void the_requesting_user_must_have_write_permissions_to_POST() { Assert.IsTrue(this.SubjectUnderTest.ActionIsProtectedByRole(c => c.Add(null), Role.Write)); } This is custom code i know, but you should get the idea, it simply checks that a filter attribute is present on the method. The point is it doesnt require any Arrange() or Act(). Any tips welcome! Thanks

• C# DynamicMethod prelink

  - by soywiz

  I'm the author of a psp emulator made in C#. I'm generating lots of "DynamicMethod" using ILGenerator. I'm converting assembly code into an AST, and then generating IL code and building that DynamicMethod. I'm doing this in another thread, so I can generate new methods while the program is executing others so it can run smoothly. My problem is that the native code generation is lazy, so the machine code is generated when the function is called, not when the IL is generated. So it generates in the program executing thread, native code generation is prettly slow as it is the asm-ast-il step. I have tried the Marshal.Prelink method that it is suposed to generate the machine code before executing the function. It does work on Mono, but it doesn't work on MS .NET. Marshal.Prelink(MethodInfo); Is there a way of prelinking a DynamicMethod on MS .NET? I thought adding a boolean parameter to the function that if set, exits the function immediately so no code is actually executed. I could "prelink" that way, but I think that's a nasty solution I want to avoid. Any idea?

• Comparing two objects that are the same in MbUnit

• How do I write a spec to verify the rendering of partials?

  - by TheDeeno

  I'm using rr and rspec. Also, I'm using the collection short hand for partial rendering. My question: How do I correctly fill out the the following spec? before(:each) do assigns[:models] = Array.new(10, stub(Model)) end it "should render the 'listing' partial for each model" do # help me write something that actually verifies this end I've tried a few examples from the rspec book, rspec docs, and rr docs. Everything I try seems to leave me with runtime errors in the test - not failed assertions. Rather than show all the transformations I've tried, I figured all I'd need if someone showed me one that actually worked. I'd be good to go from there.

• Java iteration reading & parsing

  - by Patrick Lorio

  I have a log file that I am reading to a string public static String Read (String path) throws IOException { StringBuilder sb = new StringBuilder(); InputStream in = new BufferedInputStream(new FileInputStream(path)); int r; while ((r = in.read()) != -1) { sb.append(r); } return sb.toString(); } Then I have a parser that iterates over the entire string once void Parse () { String con = Read("log.txt"); for (int i = 0; i < con.length; i++) { /* parsing action */ } } This is hugely a waste of cpu cycles. I loop over all the content in Read. Then I loop over all the content in Parse. I could just place the /* parsing action */ under the while loop in the Read method, which would be find but I don't want to copy the same code all over the place. How can I parse the file in one iteration over the contents and still have separate methods for parsing and reading? In C# I understand there is some sort of yield return thing, but I'm locked with Java. What are my options in Java?

  Currently in my tests I do something like this to test if an email is queued to be sent assert_difference('ActionMailer::Base.deliveries.size', 1) do get :create_from_spreedly, {:user_id => @logged_in_user.id} end but if i a controller action can send two different emails i.e. one to the user if sign up goes fine or a notification to admin if something went wrong - how can i test which one actually got sent. The code above would pass regardless.

• NHibernate slow mapping

  - by Rob A

  My question is what can I do to determine the cause of the slowness, or what can I do to speed it up without knowing the exact cause. I am running a simple query and it appears that the mapping back to the entities is taking taking forever. The result set is 350, which is not much data in my opinion. IRepository repo = ObjectFactory.GetInstance<IRepository>(); var q = repo.Query<Order>(item => item.Ordereddate > DateTime.Now.AddDays(-40)); foreach (var order in q) { Console.WriteLine(order.TransactionNumber); } The profiler is telling me it is executing the query 7ms / 35257ms, I am assuming that the former is the actual response from the db and the latter is the time it takes NH to do it's magic. 35 seconds is too long. This is a simple mapping, one table, nested components, using fluent interface to do mappings. I just start up a simple console app and run the one query, the slowness is measured after the SessionFactory is initialized, there should only be one session, and I am not using a transaction. Thanks

• SQL indexing on varchar

  - by alex

  I have a table whose columns are varchar(50) and a float - I need to (very quickly) look get the float associated with a given string. Even with indexing, this is rather slow. I know, however, that each string is associated with an integer, which I know at the time of lookup, so that each string maps to a unique integer, but each integer does not map to a unique string. One might think of it as a tree structure. Is there anything to be gained by adding this integer to the table, indexing on it, and using a query like SELECT floatval FROM mytable WHERE phrase=givenstring AND assoc=givenint? This is Postgres, and if you couldn't tell, I have very little experience with databases.

• Queue-like data structure with fast search and insertion

  - by Max

  I need a datastructure with the following properties: It contains integer numbers, no duplicates. After it reaches the maximal size the first element is removed. So if the capacity is 3, then this is how it would look when putting in it sequential numbers: {}, {1}, {1, 2}, {1, 2, 3}, {2, 3, 4}, {3, 4, 5} etc. Only two operations are needed: inserting a number into this container (INSERT) and checking if the number is already in the container (EXISTS). The number of EXISTS operations is expected to be approximately 2 * number of INSERT operations. I need these operations to be as fast as possible. What would be the fastest data structure or combination of data structures for this scenario?

• Massive speed diff in upgrade to Java 7

  - by Brett Rigby

  We use Java within our build process, as it is used to resolve/publish our dependencies via Ivy. No problem, nor have we had with it for 2 years, until we've tried to upgrade Java 6 Update 26 to Version 7 Update 7, whereas a build on a local developer PC (WinXP) now takes 2 hours to complete, instead of 10 minutes!! Nothing else has changed on the PC, making it the absolute target for our concerns. Does anyone know of any reason as to why version 7 of Java would make such a speed difference like this?

• [C++]Advantage of using a static member function instead of an equivalent non-static member function

  - by jonathanasdf

  I was wondering whether there's any advantages to using a static member function when there is a non-static equivalent. Will it result in faster execution (because of not having to care about all of the member variables), or maybe less use of memory (because of not being included in all instances)? Basically, the function I'm looking at is an utility function to rotate an integer array representing pixel colours an arbitrary number of degrees around an arbitrary centre point. It is placed in my abstract Bullet base class, since only the bullets will be using it and I didn't want the overhead of calling it in some utility class. It's a bit too long and used in every single derived bullet class, making it probably not a good idea to inline. How would you suggest I define this function? As a static member function of Bullet, of a non-static member function of Bullet, or maybe not as a member of Bullet but defined outside of the class in Bullet.h? What are the advantages and disadvantages of each?

• comparing two cursors in oracle instead of using MINUS

  - by Omnipresent

  The following query takes more than 3 minutes to run because tables contain massive amounts of data: SELECT RTRIM(LTRIM(A.HEAD)), A.EFFECTIVE_DATE, FROM TABLE_1 A WHERE A.TYPE_OF_ACTION='6' AND A.EFFECTIVE_DATE >= ADD_MONTHS(SYSDATE,-15) MINUS SELECT RTRIM(LTRIM(B.head)), B.EFFECTIVE_DATE, FROM TABLE_2 B In our system a query gets killed if it is running for more than 8 seconds. Is there a way to run the queries individually ..put them in cursors..compare and then get the results? that way each query will be ran individually rather than as one massive query which takes 3 minutes. How would two cursors be compared to mimic the MINUS?

  If you are developing a commercial desktop application, what's your release process? Sample process: Develop it: Patch bugs, add features, etc. Feature Freeze (do not fix, add anything unless it's absolutely required) Test it If everything is OK release it, if it's not fix it, test it, release it I think the most crucial question is what's your approach to "feature freeze test release" cycle? Or do you test it more frequently that you don't need such a cycle and your software is always ready for public release?

  i have a form, which you can pretend is laid out like Windows Explorer: panel on the left splitter client panel +------------+#+-----------------------+ | |#| | | |#| | | |#| | | |#| | | Left |#| Client | | |#| | | |#| | | |#| | | |#| | | |#| | +------------+#+-----------------------+ ^ | +----splitter The the left and client area panels are each rich with controls. The problem is that using the splitter is very sluggish. i would expect that a modern 2 GHz computer can re-display the form as fast as a human can push the mouse around. But that's definitely not the case, and it takes about 200-300 ms before the form is fully re-adjusted. The form has about 100 visual controls on it, no code, or custom controls. How do i go about tracing who's the cause of the sluggishness?
