  • How can I unit test a PHP class method that executes a command-line program?

    - by acoulton
    For a PHP application I'm developing, I need to read the current git revision SHA which of course I can get easily by using shell_exec or backticks to execute the git command line client. I have obviously put this call into a method of its very own, so that I can easily isolate and mock this for the rest of my unit tests. So my class looks a bit like this: class Task_Bundle { public function execute() { // Do things $revision = $this->git_sha(); // Do more things } protected function git_sha() { return `git rev-parse --short HEAD`; } } Of course, although I can test most of the class by mocking git_sha, I'm struggling to see how to test the actual git_sha() method because I don't see a way to create a known state for it. I don't think there's any real value in a unit test that also calls git rev-parse to compare the results? I was wondering about at least asserting that the command had been run, but I can't see any way to get a history of shell commands executed by PHP - even if I specify that PHP should use BASH rather than SH the history list comes up empty, I presume because the separate backticks executions are separate terminal sessions. I'd love to hear any suggestions for how I might test this, or is it OK to just leave that method untested and be careful with it when the app is being maintained in future?

  • Visual Studio 2008 Unit test does not pick up code changes unless I build the entire solution

    - by Orion Edwards
    Here's the scenario: Change my code: Change my unit test for that code With the cursor inside the unit test class/method, invoke VS2008's "Run tests in current context" command The visual studio "Output" window indicates that the code dll and the test dll both successfully build (in that order) The problem is however, that the unit test does not use the latest version of the dll which it has just built. Instead, it uses the previously built dll (which doesn't have the updated code in it), so the test fails. When adding a new method, this results in a MethodNotImplementedException, and when adding a class, it results in a TypeLoadException, both because the unit test thinks the new code is there, and it isn't!. If I'm just updating an existing method, then the test just fails due to incorrect results. I can 'work around' the problem by doing this Change my code: Change my unit test for that code Invoke VS2008's 'Build Solution' command With the cursor inside the unit test class/method, invoke VS2008's "Run tests in current context" command The problem is that doing a full build solution (even though nothing has changed) takes upwards of 30 seconds, as I have approx 50 C# projects, and VS2008 is not smart enough to realize that only 2 of them need to be looked at. Having to wait 30 seconds just to change 1 line of code and re-run a unit test is abysmal. Is there anything I can do to fix this? None of my code is in the GAC or anything funny like that, it's just ordinary old dll's (buiding against .NET 3.5SP1 on a win7/64bit machine) Please help!

  • what kind of credentials/prerequisites do you need to be a professional penetration tester ?

    - by dfafa
    does it take more than knowing Bt4 ? are there any one that just runs a scanner and no real labor involved ? would you be expected to be able to code your own exploits without having to dl from milw0rm and discover entry into a system by yourself, in other words, do you have to think outside the box even when there's so many tools that makes the job a lot easier ? would you ever be expected to be able to write your own scanners, exploits and etc ? i am also curious how people are able to write long pages of hex address, that magically causes some type of memory overflow...how are people guessing at the hex values for game hacks for instance ? are certification important ? what about formal school education ? I am a CS major.

  • How can I start a TCP server in the background during a Perl unit test?

    - by John
    I am trying to write a unit test for a client server application. To test the client, in my unit test, I want to first start my tcp server (which itself is another perl file). I tried to start the TCP server by forking: if (! fork()) { system ("$^X server.pl") == 0 or die "couldn't start server" } So when I call make test after perl Makefile.PL, this test starts and I can see the server starting but after that the unit test just hangs there. So I guess I need to start this server in background and I tried the & at the end to force it to start in background and then test to continue. But, I still couldn't succeed. What am I doing wrong? Thanks.

  • How to test the performance of a user's PC in/for Flash?

    - by Jan P.
    Hey, I'm a developer on nice space MMO using Flash. On new PCs performance is quite good, but some features shouldn't be enabled on older PCs because the framerate drops to shit if we do. Flash wasn't made for this, but hey, pushing boundaries is fun. An example is fullscreen mode. Of course every user can manually enable it, but "advertising" it to a user with and oldie PC would be a bad idea - but for the Alienware crowd it would be dumb not to. So I want to find out how "capable" a user's PC is to decide if I should enable or disable some features for him. Any ideas? Thanks, Sujan

  • Running single test class or group with Surefire and TestNG

    - by Slartibartfast
    I want to run single test class from command line using Maven and TestNG Things that doesn't work: mvn -Dtest=ClassName test I have defined groups in pom.xml, and this class isn't in one of those groups. So it got excluded on those grounds. mvn -Dgroups=skipped-group test mvn -Dsurefire.groups=skipped-group test when config is <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.7.1</version> <configuration> <groups>functest</groups> </configuration> </plugin> Parameters work fine in there are no groups defined in pom.xml. Similarly, when surefire is configured with <configuration> <includes> <include>**/*UnitTest.java</include> </includes> </configuration> I can add another test with -Dtest parameter, but cannot add group. In any combination, I can narrow down tests to be executed with groups, but not expand them. What's wrong with my configuration? Is there a way to run a single test or group outside of those defined in pom.xml? Tried on Ubuntu 10.04 with Maven 2.2.1, TestNG 5.14.6 and Surefire 2.7.1

  • A standard event messaging system with AJAX?

    - by Gutzofter
    Is there any standards or messaging framework for AJAX? Right now I have a single page that loads content using Ajax. Because I had a complex form for data entry as part of my content, I need to validate certain events that can occur in my form. So after some adjustments driven by my tests: asyncShould("search customer list click", 3, function() { stop(1000); $('#content').show(); var forCustomerList = newCustomerListRequest(); var forShipAndCharge = newShipAndChargeRequest(forCustomerList); forCustomerList.page = '../../vt/' + forCustomerList.page; forShipAndCharge.page = 'helpers/helper.php'; forShipAndCharge.data = { 'action': 'shipAndCharge', 'DB': '11001' }; var originalComplete = forShipAndCharge.complete; forShipAndCharge.complete = function(xhr, status) { originalComplete(xhr, status); ok($('#customer_edit').is(":visible"), 'Shows customer editor'); $('#search').click(); ok($('#customer_list').is(":visible"), 'Shows customer list'); ok($('#customer_edit').is(":hidden"), 'Does not show customer editor'); start(); }; testController.getContent(forShipAndCharge); }); Here is the controller for getting content: getContent: function (request) { $.ajax({ type: 'GET', url: request.page, dataType: 'json', data: request.data, async: request.async, success: request.success, complete: request.complete }); }, And here is the request event: function newShipAndChargeRequest(serverRequest) { var that = { serverRequest: serverRequest, page: 'nodes/orders/sc.php', data: 'customer_id=-1', complete: errorHandler, success: function(msg) { shipAndChargeHandler(msg); initWhenCustomer(that.serverRequest); }, async: true }; return that; } And here is a success handler: function shipAndChargeHandler(msg) { $('.contentContainer').html(msg.html); if (msg.status == 'flash') { flash(msg.flash); } } And on my server side I end up with a JSON structure that looks like this: $message['status'] = 'success'; $message['data'] = array(); $message['flash'] = ''; $message['html'] = ''; echo json_encode($message); So now loading content consists of two parts: HTML, this is the presentation of the form. DATA, this is any data that needs be loaded for the form FLASH, any validation or server errors STATUS tells client what happened on server. My question is: Is this a valid way to handle event messaging on the client-side or am I going down a path of heartache and pain?

  • How to test my GAE site for performance

    - by Sergey Basharov
    I am building a GAE site that uses AJAX/JSON for almost all its tasks including building the UI elements, all interactions and client-server requests. What is a good way to test it for highloads so that I could have some statistics about how much resources 1000 average users per some period of time would take. I think I can create some Python functions for this purpose. What can you advise? Thanks.

  • using a Singleton to pass credentials in a multi-tenant application a code smell?

    - by Hans Gruber
    Currently working on a multi-tenant application that employs Shared DB/Shared Schema approach. IOW, we enforce tenant data segregation by defining a TenantID column on all tables. By convention, all SQL reads/writes must include a Where TenantID = '?' clause. Not an ideal solution, but hindsight is 20/20. Anyway, since virtually every page/workflow in our app must display tenant specific data, I made the (poor) decision at the project's outset to employ a Singleton to encapsulate the current user credentials (i.e. TenantID and UserID). My thinking at the time was that I didn't want to add a TenantID parameter to each and every method signature in my Data layer. Here's what the basic pseudo-code looks like: public class UserIdentity { public UserIdentity(int tenantID, int userID) { TenantID = tenantID; UserID = userID; } public int TenantID { get; private set; } public int UserID { get; private set; } } public class AuthenticationModule : IHttpModule { public void Init(HttpApplication context) { context.AuthenticateRequest += new EventHandler(context_AuthenticateRequest); } private void context_AuthenticateRequest(object sender, EventArgs e) { var userIdentity = _authenticationService.AuthenticateUser(sender); if (userIdentity == null) { //authentication failed, so redirect to login page, etc } else { //put the userIdentity into the HttpContext object so that //its only valid for the lifetime of a single request HttpContext.Current.Items["UserIdentity"] = userIdentity; } } } public static class CurrentUser { public static UserIdentity Instance { get { return HttpContext.Current.Items["UserIdentity"]; } } } public class WidgetRepository: IWidgetRepository{ public IEnumerable<Widget> ListWidgets(){ var tenantId = CurrentUser.Instance.TenantID; //call sproc with tenantId parameter } } As you can see, there are several code smells here. This is a singleton, so it's already not unit test friendly. On top of that you have a very tight-coupling between CurrentUser and the HttpContext object. By extension, this also means that I have a reference to System.Web in my Data layer (shudder). I want to pay down some technical debt this sprint by getting rid of this singleton for the reasons mentioned above. I have a few thoughts on what an better implementation might be, but if anyone has any guidance or lessons learned they could share, I would be much obliged.

  • How can I unit test my custom validation attribute

    - by MightyAtom
    I have a custom asp.net mvc class validation attribute. My question is how can I unit test it? It would be one thing to test that the class has the attribute but this would not actually test that the logic inside it. This is what I want to test. [Serializable] [EligabilityStudentDebtsAttribute(ErrorMessage = "You must answer yes or no to all questions")] public class Eligability { [BooleanRequiredToBeTrue(ErrorMessage = "You must agree to the statements listed")] public bool StatementAgree { get; set; } [Required(ErrorMessage = "Please choose an option")] public bool? Income { get; set; } .....removed for brevity } [AttributeUsage(AttributeTargets.Class)] public class EligabilityStudentDebtsAttribute : ValidationAttribute { // If AnyDebts is true then // StudentDebts must be true or false public override bool IsValid(object value) { Eligability elig = (Eligability)value; bool ok = true; if (elig.AnyDebts == true) { if (elig.StudentDebts == null) { ok = false; } } return ok; } } I have tried to write a test as follows but this does not work: [TestMethod] public void Eligability_model_StudentDebts_is_required_if_AnyDebts_is_true() { // Arrange var eligability = new Eligability(); var controller = new ApplicationController(); // Act controller.ModelState.Clear(); controller.ValidateModel(eligability); var actionResult = controller.Section2(eligability,null,string.Empty); // Assert Assert.IsInstanceOfType(actionResult, typeof(ViewResult)); Assert.AreEqual(string.Empty, ((ViewResult)actionResult).ViewName); Assert.AreEqual(eligability, ((ViewResult)actionResult).ViewData.Model); Assert.IsFalse(((ViewResult)actionResult).ViewData.ModelState.IsValid); } The ModelStateDictionary does not contain the key for this custom attribute. It only contains the attributes for the standard validation attributes. Why is this? What is the best way to test these custom attributes? Thanks

  • What is a good programming language for testers who are not great programmers?

    - by Brian T Hannan
    We would like to create some simple automated tests that will be created and maintained by testers. Right now we have a tester who can code in any language, but in the future we might want any tester with a limited knowledge of programming to be able to add or modify the tests. What is a good programming language for testers who are not great programmers, or programmers at all? Someone suggested LUA, but I looked into LUA and it might be more complicated that another language would be. Preferably, the language will be interpreted and not be compiled. Let me know what you think.

  • How do I set up a test duplicate of a Django and Postgresql based web application?

    - by cojadate
    Not sure if this is an excessively broad and newbie-ish question for Stack Overflow but here goes: I paid someone else to build a web application for me and now I want to tweak certain aspects of it myself. I learn best by trial and error – changing stuff and seeing what happens. Obviously that's not a great way to treat a live site, so I need to duplicate the site on some kind of test server which I can play with without fear of the consequences. Unfortunately the closest I've come to programming has been creating ActionScript-based websites. I've never touched a database. So I really don't know where to start with setting up a test server. I would really appreciate any advice about where to start. I am completely ignorant and lost here. The web application is built in python/django using a Postgresql database. I use Mac OS X 10.6 if that makes any difference.

  • Using Rails and Rspec, how do you test that the database is not touched by a method

    - by Will Tomlins
    So I'm writing a test for a method which for performance reasons should achieve what it needs to achieve without using SQL queries. I'm thinking all I need to know is what to stub: describe SomeModel do describe 'a_getter_method' do it 'should not touch the database' do thing = SomeModel.create something_inside_rails.should_not_receive(:a_method_querying_the_database) thing.a_getter_method end end end EDIT: to provide a more specific example: class Publication << ActiveRecord::Base end class Book << Publication end class Magazine << Publication end class Student << ActiveRecord::Base has_many :publications def publications_of_type(type) #this is the method I am trying to test. #The test should show that when I do the following, the database is queried. self.publications.find_all_by_type(type) end end describe Student do describe "publications_of_type" do it 'should not touch the database' do Student.create() student = Student.first(:include => :publications) #the publications relationship is already loaded, so no need to touch the DB lambda { student.publications_of_type(:magazine) }.should_not touch_the_database end end end So the test should fail in this example, because the rails 'find_all_by' method relies on SQL.

  • Test assertions for tuples with floats

    - by Space_C0wb0y
    I have a function that returns a tuple that, among others, contains a float value. Usually I use assertAlmostEquals to compare those, but this does not work with tuples. Also, the tuple contains other data-types as well. Currently I am asserting every element of the tuple individually, but that gets too much for a list of such tuples. Is there any good way to write assertions for such cases?

  • Embedded MongoDB when running integration tests

    - by seanhodges
    My question is a variation of this one. Since my Java Web-app project requires a lot of read filters/queries and interfaces with tools like GridFS, I'm struggling to think of a sensible way to simulate MongoDB in the way the above solution suggests. Therefore, I'm considering running an embedded instance of MongoDB alongside my integration tests. I'd like it to start up automatically (either for each test or the whole suite), flush the database for every test, and shut down at the end. These tests might be run on development machines as well as the CI server, so my solution will also need to be portable. Can anyone with more knowledge on MongoDB help me get idea of the feasibility of this approach, and/or perhaps suggest any reading material that might help me get started? I'm also open to other suggestions people might have on how I could approach this problem...

  • Automating site interaction

    - by Leocer
    I'm working with a CMS and need to import data to it using typical html forms. The data itself is in csv files with one page per row. Such is the CMS that importing directly to db isn't possible due to the complexity of the design. It's pretty important that i "fake" usual user interaction because the CMS does a lot of background work that's crucial for the import. Basically, for each row in the csv file, I need to copy a csv column to a html textfield, or select a checkbox, or click a certain button. One major issue is mapping the data in the csv to actions in the CMS. So if one column contains the string 'foobar' is really means "set the firstName dropdown widget to 'foobar'". Is there a tool to automate this? I´ve been looking at AutoHotKey, Selendium, Web-Harvester and many other tools but I'm not convinced they are the correct tools. The main problem is being able to interact with the html pages in a easy way.

  • How can I unit test an Android Activity that acts on Accelerometer?

    - by Corey Sunwold
    I am starting with an Activity based off of this ShakeActivity and I want to write some unit tests for it. I have written some small unit tests for Android activities before but I'm not sure where to start here. I want to feed the accelerometer some different values and test how the activity responds to it. For now I'm keeping it simple and just updating a private int counter variable and a TextView when a "shake" event happens. So my question largely boils down to this: How can I send fake data to the accelerometer from a unit test?

  • Why does this asp.net mvc unit test fail?

    - by Brian McCord
    I have this unit test: [TestMethod] public void Delete_Post_Passes_With_State_4() { //Arrange ViewResult result = stateController.Delete( 4 ) as ViewResult; var model = (State)result.ViewData.Model; //Act RedirectToRouteResult redirectResult = stateController.Delete( model ) as RedirectToRouteResult; var newresult = stateController.Delete( 4 ) as ViewResult; var newmodel = (State)newresult.ViewData.Model; //Assert Assert.AreEqual( redirectResult.RouteValues["action"], "Index" ); Assert.IsNull( newmodel ); } Here are the two controller actions that handle deleting: // // GET: /State/Delete/5 public ActionResult Delete(int id) { var x = _stateService.GetById( id ); return View(x); } // // POST: /State/Delete/5 [HttpPost] public ActionResult Delete(State model) { try { if( model == null ) { return View( model ); } _stateService.Delete( model ); return RedirectToAction("Index"); } catch { return View( model ); } } What I can't figure out is why this test fails. I have verified that the record actually gets deleted from the list. If I set a break point in the Delete method on the line: var x = _stateService.GetById( id ); The GetById does indeed return a null just as it should, but when it gets back to the newresult variable in the test, the ViewData.Model is the deleted model. What am I doing wrong?
