• How test a Delphi app with Application Verifier 4.0?

  - by mamcx

  I download the Application Verifier 4.0 to test my App for check if could have problems on Vista/7. I run from Delphi 2010 debugger, and stop in CPU view. Obviously, I don't understand anything about assembler!. So, I try running directly from the windows explorer, and the App die. (In fact, I don't understand well what exactly will do App Verifier: I expect some kind of friendly message). This is what i get: 7C81A3E2 C3 ret 7C81A3E3 90 nop 7C81A3E4 8BFF mov edi,edi ntdll.DbgUserBreakPoint: 7C81A3E6 CC int 3 7C81A3E7 C3 ret 7C81A3E8 8BFF mov edi,edi 7C81A3EA 8B442404 mov eax,[esp+$04] 7C81A3EE CC int 3 7C81A3EF C20400 ret $0004 ntdll.NtCurrentTeb: 7C81A3F2 64A118000000 mov eax, fs:[$00000018] 7C81A3F8 C3 ret ntdll.RtlInitString: 7C81A3F9 57 push edi Loading: :7c81a3e2 ntdll.DbgBreakPoint + 0x1 :10003b68 ; C:\WINDOWS\system32\vrfcore.dll :00396a9d ; C:\WINDOWS\system32\vfbasics.dll :00397316 ; C:\WINDOWS\system32\vfbasics.dll :7c84bcdb ; ntdll.dll :7c8316f8 ; ntdll.dll :7c83154f ; ntdll.dll :7c82855e ntdll.KiUserExceptionDispatcher + 0xe :0040aa00 GetUILanguages + $80 :0040b298 GetResourceModuleName + $124 :0040afde LoadResourceModule + $7A :0040a134 DelayLoadResourceModule + $2C :00406c40 @StartExe + $44 :77e6f23b ; C:\WINDOWS\system32\KERNEL32.dll

• How do you unit test a method containing a LINQ expression?

  - by Phil.Wheeler

  I'm struggling to get my head around how to accommodate a mocked method that only accepts a Linq expression as its argument. Specifically, the repository I'm using has a First() method that looks like this: public T First(Expression<Func<T, bool>> expression) { return All().Where(expression).FirstOrDefault(); } The difficulty I'm encountering is with my MSpec tests, where I'm (probably incorrectly) trying to mock that call: public abstract class with_userprofile_repository { protected static Mock<IRepository<UserProfile>> repository; Establish context = () => { repository = new Mock<IRepository<UserProfile>>(); repository.Setup<UserProfile>(x => x.First(up => up.OpenID == @"http://testuser.myopenid.com")).Returns(GetDummyUser()); }; protected static UserProfile GetDummyUser() { UserProfile p = new UserProfile(); p.OpenID = @"http://testuser.myopenid.com"; p.FirstName = "Joe"; p.LastLogin = DateTime.Now.Date.AddDays(-7); p.LastName = "Bloggs"; p.Email = "[email protected]"; return p; } } I run into trouble because it's not enjoying the Linq expression: System.NotSupportedException: Expression up = (up.OpenID = "http://testuser.myopenid.com") is not supported. So how does one test these sorts of scenarios?

• Android java.lang.VerifyError for private method with annotated argument.

  - by alex2k8

  I have a very simple project that compiles, but can't be started on Emulator. The problem is with this method: private void bar(@Some String a) {} // java.lang.VerifyError The issue can be avoided if annotation removed private void bar(String a) {} // OK or the method visibility changed: void bar(@Some String a) {} // OK public void bar(@Some String a) {} // OK protected void bar(@Some String a) {} // OK Any idea what is wrong with original method? Is this a dalvik bug, or? If some one whould like to experiment with code, here it is: Test.java: public class Test { private void bar(@Some String a) {} public void foo() { bar(null); } } Some.java: public @interface Some {} MainActivity.java: public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); new Test().foo(); } } Stack trace: ERROR/dalvikvm(1358): Could not find method com.my.Test.bar, referenced from method com.my.Test.foo WARN/dalvikvm(1358): VFY: unable to resolve direct method 11: Lcom/my/Test;.bar (Ljava/lang/String;)V WARN/dalvikvm(1358): VFY: rejecting opcode 0x70 at 0x0001 WARN/dalvikvm(1358): VFY: rejected Lcom/my/Test;.foo ()V WARN/dalvikvm(1358): Verifier rejected class Lcom/my/Test; DEBUG/AndroidRuntime(1358): Shutting down VM WARN/dalvikvm(1358): threadid=3: thread exiting with uncaught exception (group=0x4000fe70) ERROR/AndroidRuntime(1358): Uncaught handler: thread main exiting due to uncaught exception ERROR/AndroidRuntime(1358): java.lang.VerifyError: com.my.Test ERROR/AndroidRuntime(1358): at com.my.MainActivity.onCreate(MainActivity.java:13) ERROR/AndroidRuntime(1358): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1123) ERROR/AndroidRuntime(1358): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2231) ERROR/AndroidRuntime(1358): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2284) ERROR/AndroidRuntime(1358): at android.app.ActivityThread.access$1800(ActivityThread.java:112) ERROR/AndroidRuntime(1358): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1692) ERROR/AndroidRuntime(1358): at android.os.Handler.dispatchMessage(Handler.java:99) ERROR/AndroidRuntime(1358): at android.os.Looper.loop(Looper.java:123) ERROR/AndroidRuntime(1358): at android.app.ActivityThread.main(ActivityThread.java:3948) ERROR/AndroidRuntime(1358): at java.lang.reflect.Method.invokeNative(Native Method) ERROR/AndroidRuntime(1358): at java.lang.reflect.Method.invoke(Method.java:521) ERROR/AndroidRuntime(1358): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:782) ERROR/AndroidRuntime(1358): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:540) ERROR/AndroidRuntime(1358): at dalvik.system.NativeStart.main(Native Method)

• NMock2.0 - how to stub a non interface call?

  - by dferraro

  Hello, I have a class API which has full code coverage and uses DI to mock out all the logic in the main class function (Job.Run) which does all the work. I found a bug in production where we werent doing some validation on one of the data input fields. So, I added a stub function called ValidateFoo()... Wrote a unit test against this function to Expect a JobFailedException, ran the test - it failed obviously because that function was empty. I added the validation logic, and now the test passes. Great, now we know the validation works. Problem is - how do I write the test to make sure that ValidateFoo() is actually called inside Job.Run()? ValidateFoo() is a private method of the Job class - so it's not an interface... Is there anyway to do this with NMock2.0? I know TypeMock supports fakes of non interface types. But changing mock libs right now is not an option. At this point if NMock can't support it, I will simply just add the ValidateFoo() call to the Run() method and test things manually - which obviously I'd prefer not to do considering my Job.Run() method has 100% coverage right now. Any Advice? Thanks very much it is appreciated. EDIT: the other option I have in mind is to just create an integration test for my Job.Run functionality (injecting to it true implementations of the composite objects instead of mocks). I will give it a bad input value for that field and then validate that the job failed. This works and covers my test - but it's not really a unit test but instead an integration test that tests one unit of functionality.... hmm.. EDIT2: IS there any way to do tihs? Anyone have ideas? Maybe TypeMock - or a better design?

• Layout of Ant build.xml with junit tests

  - by Derk

  In a project I have a folder src for all application source code and a different folder test for all junit test (both with a simular package hierarchy). Now I want that Ant can run all tests in in test folder, bot the problem is that now also files in the src folder with "Test" in the filename are included. This is the test target in the build.xml: <target name="test" depends="build"> <mkdir dir="reports/tests" /> <junit fork="yes" printsummary="yes"> <formatter type="xml"/> <classpath> <path location="${build}/WEB-INF/classes"/> <fileset dir="${projectname.home}/lib"> <include name="servlet-api.jar"/> <include name="httpunit.jar"/> <include name="Tidy.jar"/> <include name="js.jar"/> <include name="junit.jar"/> </fileset> </classpath> <batchtest todir="reports/tests"> <fileset dir="${build}/WEB-INF/classes"> <include name="**/*Test.class"/> </fileset> </batchtest> </junit> And I have added the test folder to the build target: <target name="build" depends="init,init-props,prepare"> <javac source="1.5" debug="true" destdir="${build}/WEB-INF/classes"> <src path="src" /> <src path="test" /> <classpath refid="classpath"/> </javac> </target>

• Enums, Constructor overloads with similar conversions.

  - by David Thornley

  Why does VisualC++ (2008) get confused 'C2666: 2 overloads have similar conversions' when I specify an enum as the second parameter, but not when I define a bool type? Shouldn't type matching already rule out the second constructor because it is of a 'basic_string' type? #include <string> using namespace std; enum EMyEnum { mbOne, mbTwo }; class test { public: #if 1 // 0 = COMPILE_OK, 1 = COMPILE_FAIL test(basic_string<char> myString, EMyEnum myBool2) { } test(bool myBool, bool myBool2) { } #else test(basic_string<char> myString, bool myBool2) { } test(bool myBool, bool myBool2) { } #endif }; void testme() { test("test", mbOne); } I can work around this by specifying a reference 'ie. basic_string &myString' but not if it is 'const basic_string &myString'. Also calling explicitly via "test((basic_string)"test", mbOne);" also works. I suspect this has something to do with every expression/type being resolved to a bool via an inherent '!=0'. Curious for comments all the same :)

• How do I see items embedded/attached to my Gallio test log in CruiseControl.NET?

  - by GraemeF

  I can use the following code to attach a log file to my Gallio 3.2 acceptance test report: TestLog.AttachPlainText("Attached log file", File.ReadAllText(path)); When I run my tests locally I can see the log file contents by viewing the report in my web browser. However, if I run the tests under CCNET 1.4.4 I get the following error when I try to browse to an attached file in the report via the web dashboard: Exception Message The attachment was not inlined into the XML report. Exception Full Details System.InvalidOperationException: The attachment was not inlined into the XML report. at CCNet.Gallio.WebDashboard.Plugin.GallioAttachmentBuildAction.CreateResponseFromAttachment(XPathNavigator attachmentNavigator) at CCNet.Gallio.WebDashboard.Plugin.GallioAttachmentBuildAction.Execute(ICruiseRequest cruiseRequest) at ThoughtWorks.CruiseControl.WebDashboard.MVC.Cruise.ServerCheckingProxyAction.Execute(ICruiseRequest cruiseRequest) at ThoughtWorks.CruiseControl.WebDashboard.MVC.Cruise.BuildCheckingProxyAction.Execute(ICruiseRequest cruiseRequest) at ThoughtWorks.CruiseControl.WebDashboard.MVC.Cruise.ProjectCheckingProxyAction.Execute(ICruiseRequest cruiseRequest) at ThoughtWorks.CruiseControl.WebDashboard.MVC.Cruise.CruiseActionProxyAction.Execute(IRequest request) at ThoughtWorks.CruiseControl.WebDashboard.MVC.Cruise.CachingActionProxy.Execute(IRequest request) at ThoughtWorks.CruiseControl.WebDashboard.MVC.Cruise.ExceptionCatchingActionProxy.Execute(IRequest request) I get similar results when I try to embed the file instead with: TestLog.EmbedPlainText("Embedded log file", File.ReadAllText(path)); Is it possible to get this working?

• Git: Create a branch from unstagged/uncommited changes on master

  - by knoopx

  Context: I'm working on master adding a simple feature. After a few minutes I realize it was not so simple and it should have been better to work into a new branch. This always happens to me and I have no idea how to switch to another branch and take all these uncommited changes with me leaving the master branch clean. I supposed git stash && git stash branch new_branch would simply accomplish that but this is what I get: ~/test $ git status # On branch master nothing to commit (working directory clean) ~/test $ echo "hello!" > testing ~/test $ git status # On branch master # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: testing # no changes added to commit (use "git add" and/or "git commit -a") ~/test $ git stash Saved working directory and index state WIP on master: 4402b8c testing HEAD is now at 4402b8c testing ~/test $ git status # On branch master nothing to commit (working directory clean) ~/test $ git stash branch new_branch Switched to a new branch 'new_branch' # On branch new_branch # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: testing # no changes added to commit (use "git add" and/or "git commit -a") Dropped refs/stash@{0} (db1b9a3391a82d86c9fdd26dab095ba9b820e35b) ~/test $ git s # On branch new_branch # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: testing # no changes added to commit (use "git add" and/or "git commit -a") ~/test $ git checkout master M testing Switched to branch 'master' ~/test $ git status # On branch master # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: testing # no changes added to commit (use "git add" and/or "git commit -a") Do you know if there is any way of accomplishing this?

• How to keep your unit tests simple and isolated and still guarantee DDD invariants ?

  - by ian31

  DDD recommends that the domain objects should be in a valid state at any time. Aggregate roots are responsible for guaranteeing the invariants and Factories for assembling objects with all the required parts so that they are initialized in a valid state. However this seems to complicate the task of creating simple, isolated unit tests a lot. Let's assume we have a BookRepository that contains Books. A Book has : an Author a Category a list of Bookstores you can find the book in These are required attributes : a book has to have an author, a category and at least a book store you can buy the book from. There's likely to be a BookFactory since it is quite a complex object, and the Factory will initialize the Book with at least all the mentioned attributes. Now we want to unit test a method of the BookRepository that returns all the Books. To test if the method returns the books, we have to set up a test context (the Arrange step in AAA terms) where some Books are already in the Repository. If the only tool at our disposal to create Book objects is the Factory, the unit test now also uses and is dependent on the Factory and inderectly on Category, Author and Store since we need those objects to build up a Book and then place it in the test context. Would you consider this is a dependency in the same way that in a Service unit test we would be dependent on, say, a Repository that the Service would call ? How would you solve the problem of having to re-create a whole cluster of objects in order to be able to test a simple thing ? How would you break that dependency and get rid of all these attributes we don't need in our test ? By using mocks or stubs ? If you mock up things a Repository contains, what kind of mock/stubs would you use as opposed to when you mock up something the object under test talks to or consumes ?

• Java Package - To create a button and import one when needed.

  - by Zopyrus

  This is more like a package/import test. We'll start with my base folder at .../javaf/test.java My goal is to create subcategory and create a class with a button that I can import to test.java when I need a button. I feel like I've done it right, I know that the button doesn't do anything as of now, but I just want to make the whole thing work and expand the code thereafter. So here goes - This is test.java import paket.*; // importing classes from subcategory paket! import javax.swing.*; import java.awt.*; import java.awt.event.*; import java.util.*; public class test { public test() { JFrame myFrame; JPanel myPanel; myFrame = new JFrame("Hello FramWorld"); myPanel = new JPanel(); // Here I want to add the object created in paket/myButts.java // The problem is how to make these two lines work. myButts myButton = new myButts(); myPanel.add(myButton); myFrame.setVisible(true); myFrame.getContentPane().add(myPanel, BorderLayout.CENTER); myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); myFrame.pack(); } public static void main(String args[]) { new test(); } } And here is my .../javaf/paket/myButts.java package paket; // Here is the package function (ought to work like a link) import javax.swing.*; import java.awt.*; import java.awt.event.*; // This class should only create a button. public class myButts { public myButts() { JButton myButt = new JButton(); } } I've compiled myButts.java with no errors. But then I compile test.java and it gives me the following error: test.java:19: cannot find symbol symbol : method add(paket.myButts) location: class javax.swing.JPanel myPanel.add(myButton); Thanks for reading, Z

• Jquery .wrap and first-child

  - by Johann

  Hi, I'm in a situation in which I need to use .wrap and :first-child. This is what I am doing: <script>$("a").wrap("<div class='category-wrapper'></div>");</script> <script>$("div.category-wrapper:first-child").addClass("first");</script> This should render a div.category-wrapper outside a link and then add a "first" class to every first div.category-wrapper. The output is: <div class="category-wrapper"><a href="#">Test</a></div> Which is good! However, I am not able to get the "first-child" to work (it doesn't adds the "first" class). If I use it somewhere else it works so I am sure it's something related to the dynamic rendering of the previous element. Any help is appreciated! Thanks! Sample output would be: <div class="category-wrapper"><a href="#">Test #1</a></div> <div class="category-wrapper"><a href="#">Test #2</a></div> <div class="category-wrapper"><a href="#">Test #3</a></div> <div class="category-wrapper"><a href="#">Test #4</a></div> Desired output: <div class="category-wrapper first"><a href="#">Test #1</a></div> <div class="category-wrapper"><a href="#">Test #2</a></div> <div class="category-wrapper"><a href="#">Test #3</a></div> <div class="category-wrapper"><a href="#">Test #4</a></div> However, I am not able to make it work.

(NOTE: The following code is from a bigger program, this is just a sample, but all structures and arrays used are needed as declared ) The contents of the file being tested are simply: 5 4 3 2 5 3 4 2 #include<stdio.h> #define first 500 #define sec 500 struct trial{ int f; int r; float what[first][sec]; }; int trialtest(trial *test); int trialdisplay(trial *test); main(){ trial test; trialtest(&test); trialdisplay(&test); } int trialtest(trial *test){ int z,x,i; FILE *inputf; inputf=fopen("randomfile.txt","r"); for(i=0;i<5;i++){ fscanf(inputf,"%f",&(*test).what[z][x]); } fclose(inputf); return 0; } int trialdisplay(trial *test){ int i,z,x; printf("printing\n\n\n"); for (i=0;i<10;i++){ printf("%f",(*test).what[z][x]); } return 0; } The problem is, I get this error whenever I run the code .. I cant really understand whats going on : Any suggestions ? Thanks alot !

• Dangers when deploying Flash/Flex UI test automation hooks to production?

  - by Merlyn Morgan-Graham

  I am interested in doing automated testing against a Flex based UI. I have found out that my best options for UI automation (due to being C# controllable, good licensing conditions, etc) all seem to require that I compile test hooks into my application. Because of this, I am thinking of recommending that these hooks be compiled into our build. I have found a few places on the net that recommend not deploying bits with this instrumentation enabled, and I'd like to know why. Is it a performance drain, or a security risk? If it is a security risk, can you explain how the attack surface is increased? I am not a Flash or Flex developer, though I have some experience with threat modeling. For reference, here's the tools I'm specifically considering: QTP Selenium-Flex API I am having problems finding all the warnings/suggestions I found last night, but here's an example that I can find: http://www.riatest.com/products/getting-started.html Warning! Automation enabled applications expose all properties of all GUI components. This makes them vulnerable to malicious use. Never make automation enabled application publicly available. Always restrict access to such applications and to RIATest Loader to trusted users only.

• How to use two parameters pointing to the same structure in one function ?

  - by ZaZu

  Hey guys, I have my code below that consits of a structure, a main, and a function. The function is supposed to display two parameters that have certain values, both of which point to the same structure. The problem I dont know how to add the SECOND parameter onto the following code : #include<stdio.h> #define first 500 #define sec 500 struct trial{ int f; int r; float what[first][sec]; }; int trialtest(trial *test); main(){ trial test; trialtest(&test); } int trialtest(trial *test){ int z,x,i; for(i=0;i<5;i++){ printf("%f,(*test).what[z][x]); } return 0; } I need to add a new parameter test_2 there (IN THE SAME FUNCTION) using this code : for(i=0;i<5;i++){ printf("%f,(*test_2).what[z][x]); How does int trialtest(trial *test) changes ? and how does it change in main ? I know that I should declare test_2 as well, like this : trial test,test_2; But what about passing the address in the function ? I do not need to edit it right ? trialtest(&test); --- This will remain the same ? So please, tell me how would I use test_2 as a parameter pointing to the same structure as test, both in the same function.. Thank you !! Please tell me if you need more clarification

• Comparing strings that contain formatting in C#

  - by Finglas

  I'm working on a function that given some settings - such as line spacing, the output (in string form) is modified. In order to test such scenarios, I'm using string literals, as shown below for the expected result. The method, using a string builder, (AppendLine) generates the said output. One issue I have run into is that of comparing such strings. In the example below, both are equal in terms of what they represent. The result is the area which I care about, however when comparing two strings, one literal, one not, equality naturally fails. This is because one of the strings emits line spacing, while the other only demonstrates the formatting it contains. What would be the best way of solving this equality problem? I do care about formatting such as new lines from the result of the method, this is crucially important. Code: string expected = @"Test\n\n\nEnd Test."; string result = "Test\n\n\nEnd Test"; Console.WriteLine(expected); Console.WriteLine(result); Output: Test\n\n\nEnd Test. Test End Test

• Hibernate Transient Extends problem

  - by mrvreddy

  @MappedSuperclass public abstract class BaseAbstract implements Serializable{ private static final long serialVersionUID = 1L; protected String test = //some random value; public String getTest() { return test; } public void setTest(String test){ this.test = test; } } @Entity public class Artist extends BaseAbstract { private static final long serialVersionUID = 1L; private Integer id; @override @Transient public String getTest() { return test; } ..... } My question is... when i am trying to do any operation on the artist, along with id and name, test is also getting saved which should not be the case... if i add the same transient on the baseabstract class getTest() method, i see test column NOT getting created(ideally what it should happen) but if i try to override the method with adding annotaion in the sub class it creates the test column... I dont know why this is happening since when hibernate is creating the artist object and checks for annotations, it should see the transient annotation present on the getTest() of artist method...and should not create a column in the database... Let me know if you need any clarification.... Any response on this is greatly appreciated.... Thank you

• How to test whether a char is NOT in a string? (java, junit)

  - by JB

  As title says, im having trouble with my junit tests passing for checking if a character is not in a string and how to check if an empty string doesnt have a character. here is the method i have: public static boolean isThere(String s, char value){ for(int x = 0; x <= s.length(); x++){ if(s.charAt(x) == value){ return true; } else if(s.length() == 0){ return false; } } return false; And here is the junit test: public void testIsThere() { { String sVal = "Jeff George"; boolean hasA = StringMethods.isThere(sVal,'e'); assertTrue(hasA); boolean hasE = StringMethods.isThere(sVal, 'o'); assertTrue(hasE); boolean notIn = StringMethods.isThere(sVal,'b'); assertTrue(notIn); } { String sVal = ""; boolean nothingIn = StringMethods.isThere(sVal,'a'); assertFalse(nothingIn); boolean notIn = StringMethods.isThere(sVal,'b'); assertFalse(notIn); } } Thank you very much, appreciated

• CMD For Loop does not hold set /a value

  - by Bob Hope

  Didn't know how to explain this well, so here is the code @echo off set test=0 for /f %%a in (textfile.txt) do ( rem loops five times(5 lines in textfile.txt) set /a test=test+1 rem Adds 1 to Test echo %%a rem Echo's correct line in file echo %test% rem Echo's whatever X was before the loop ) echo %test% rem Displays the correct value of X pause this is just an example of where I am finding the problem, txtfile.txt has 5 lines, so the for loop goes 5 times, each time, test gets +1 to it, and the /a displays the correct value of X, but the last echo on the for loop displays 0, which is what test is set to before the loop. The value of test is not changing until the loop is finished... is there any way to fix this? Here is what I want to accomplish, as there may be an easier way: I want to run a for loop that findstr's all rtf's in a series of sub folders, and copies them all to a all directory with a new name, 1.rtf,2.rtf,3.rtf, etc. The reason I need to rename them on the transfer is they all have the same name.
