  • design pattern for unit testing?

    - by Maddy.Shik
    I am beginner in developing test cases, and want to follow good patterns for developing test cases rather than following some person or company's specific ideas. Some people don't make test cases and just develop the way their senior have done in their projects. I am facing lot problems like object dependencies (when want to test method which persist A object i have to first persist B object since A is child of B). Please suggest some good books or sites preferably for learning design pattern for unit test cases. Or reference to some good source code or some discussion for Dos and Donts will do wonder. So that i can avoid doing mistakes be learning from experience of others.

  • Area of testing

    - by ?????? ??????????
    I'm trying to understand which part of my code I should to test. I have some code. Below is example of this code, just to understand the idea. Depends of some parametrs I put one or another currency to "Event" and return his serialization in the controller. Which part of code I should to test? Just the final serialization, or only "Event" or every method: getJson, getRows, fillCurrency, setCurrency? class Controller { public function getJson() { $rows = $eventManager->getRows(); return new JsonResponse($rows); } } class EventManager { public function getRows() { //some code here if ($parameter == true) { $this->fillCurrency($event, $currency); } } public function fillCurrency($event, $currency) { //some code here if ($parameters == true) { $event->setCurrency($currency); } } } class Event { public function setCurrency($currency) { $this->updatedAt = new Datetime(); $this->currency = $currency; } }

  • Unit testing a database connection and general questions on database-dependent code and unit testing

    - by dotnetdev
    Hi, If I have a method which establishes a database connection, how could this method be tested? Returning a bool in the event of a successful connection is one way, but is that the best way? From a testability method, is it best to have the connection method as one method and the method to get data back a seperate method? Also, how would I test methods which get back data from a database? I may do an assert against expected data but the actual data can change and still be the right resultset. EDIT: For the last point, to check data, if it's supposed to be a list of cars, then I can check they are real car models. Or if they are a bunch of web servers, I can have a list of existant web servers on the system, return that from the code under test, and get the test result. If the results are different, the data is the issue but the query not? THnaks

  • How much detail is in a good UI regression test?

    - by GlenPeterson
    We use a detailed step-by-step user-interface regression test for our commercial web application. It has a "backbone" test for the most used / most important parts of the system, with optional tests for specific areas of functionality. Using this plan has definitely helped us ensure high quality software. But, having very specific tests can be counter-productive. The tester concentrates on following the test and will completely miss usability issues, or not notice fairly obvious problems such as the bottom part of a page that is missing. By contrast, some of the best UI testing happens when building a demo of a new feature. I often do my own best testing by pretending to demonstrate the system to an imaginary prospect. Yet when I tell the testers, "Just demonstrate the system to yourself" they don't cover nearly as much functionality as they do with a detailed point-by-point test. I'm repeatedly asked to provide more and more detail in the test plan so that a new untrained tester can test with it without asking any questions. Yet details seem to be counter-productive. How much detail do you put in a regression test to make it effective? What techniques make the tester to focus more on the system than on checking off items on the test?

  • Help With Database Layout

    - by three3
    Hello everyone, I am working on a site similar to Craigslist where users can make postings and sell items in different cities. One difference between my site and Craigslist will be you will be able to search by zip code instead of having all of the cities listed on the page. I already have the ZIP Code database that has all of the city, state, latitude, longitude, and zip code info for each city. Okay, so to dive into what I need done and what I need help with: 1.) Although I have the ZIP Code database, it is not setup perfectly for my use. (I downloaded it off of the internet for free from http://zips.sourceforge.net/) 2.) I need help setting up my database structure (Ex: How many different tables should I use and how should I link them) I will be using PHP and MySQL. These our my thoughts so far on how the database can be setup: (I am not sure if this will work though.) Scenario: Someone goes to the homepage and it will tell them, "Please enter your ZIP Code.". If they enter "17241" for example, this ZIP Code is for a city named Newville located in Pennsylvania. The query would look like this with the current database setup: SELECT city FROM zip_codes WHERE zip = 17241; The result of the query would be "Newville". The problem I see here now is when they want to post something in the Newville section of the site, I will have to have an entire table setup just for the Newville city postings. There are over 42,000 cities which means I would have to have over 42,000 tables (one for each city) so that would be insane to have to do it that way. One way I was thinking of doing it was to add a column to the ZIP Code database called "city_id" which would be a unique number assigned to each city. So for example, the city Newville would have a city_id of 83. So now if someone comes and post a listing in the city Newville I would only need one other table. That one other table would be setup like this: CREATE TABLE postings ( posting_id INT NOT NULL AUTO_INCREMENT, for_sale LONGTEXT NULL, for_sale_date DATETIME NULL, for_sale_city_id INT NULL, jobs LONGTEXT NULL, jobs_date DATETIME NULL, jobs_city_id INT NULL, PRIMARY KEY(posting_id) ); (The for_sale and job_ column names are categories of the types of postings users will be able to list under. There will be many more categories than just those two but this is just for example.) So now when when someone comes to the website and they are looking for something to buy and not sell, they can enter their ZIP Code, 17241, for example, and this is the query that will run: SELECT city, city_id FROM zip_codes WHERE zip = 17241; //Result: Newville 83 (Please note that I will be using PHP to store the ZIP Code the user enters in SESSIONS and Cookies to remember them throughout the site) Now it will tell them, "Please choose your category.". If they choose the category "Items For Sale" then this is the query to run and sort the results: SELECT posting_id, for_sale, for_sale_date FROM postings WHERE for_sale_city_id = $_SESSION['zip_code']; Will this work? So now my question to everyone is will this work? I am pretty sure it will but I do not want to set this thing up and realize I overlooked something and have to start from all over from scratch. Any opinions and ideas are welcomed and I will listen to anyone who has some thoughts. I really appreciate the help in advance :D

  • Oracle Database 11g R2 támogatott SAP alatt is

    - by Lajos Sárecz
    Húsvét óta már SAP alatt is használható az Oracle Database 11g R2. Köztudott, hogy az SAP csak a Release 2-re ad ki támogatást, így ez most egy igazán örömteli hír az SAP felhasználóknak, hiszen az alábbi 11g R2 újdonságokat tudják alkalmazni SAP környezetben: • Advanced Compression opció (táblára, RMAN mentésre, expdp-re, Data Guard hálózatra) • Real Application Testing • Oracle Database 11g Release 2 Database Vault • Oracle Database 11g Release 2 RAC • Advanced Encryption táblaterekre, RMAN mentésekre, expdp-re, Data Guard hálózatra • Direct NFS • Deferred Segments • Online Patching Azaz például tömöríthetové válik az SAP adatbázisa, vagy az abból készített mentések. Az eddigi tapasztalatok szerint a tömörítés aránya adatbázistól függoen 2-4-szeres. Az adatbázis upgrade és minden egyéb adatbázis infrastruktúrát érinto változatatás kockázata jelentosen csökkentheto lesz a Real Application Testing alkalmazásával. A rendszergazdai szerepkörök szeparaláhatóvá válnak a Database Vault felhasználásával. A Real Application Clusters 11g R2 újdonságai is elérheto lesznek. A Transparent Data Encryption révén a táblaterek és a mentések titkosíthatók úgy, hogy az alkalmazás számára mindez transzparens, azonban a médiához közvetlenül hozzáférve nem lesznek visszafejthetok az adatok. Támogatott lesz a Direct NFS kliens, ezzel NFS elérési sebesség jelentosen javul. A Deffered Segments révén pedig a tábla szegmensek csak akkor kerülnek lefoglalásra, amikor adat kerül a táblába. Ez azért hasznos, mert általában alkalmazások telepítésekor létrejön minden tábla, azonban sok táblába nem kerül adat. Ezáltal mind a telepítés ideje, mind az adatbázis mérete csökkentheto. Az Online Patching pedig lehetové teszi a leállításmentes patch telepítést. Hát azt gondolom ezek vonzó lehetoségek, érdemes betervezni a közeljövobe az SAP rendszerek alatti adatbázis frissítését, hiszen a 10g verzió Premier Support idén nyáron lejár. Az upgrade-hez pedig mindenképp javaslom a Real Application Testing használatát, amivel az éles terhelés mellett teszthelheto teszt környezetben az upgrade. A Sun Oracle Database Machine és az Exadata sajnos még nem támogatott SAP alatt, mivel az ASM certifikáció még nem zárult le. A hírek szerint 2011 elejére várható, hogy ez megtörténik.

  • SharePoint Unit Testing and Load Testing Finally?

    - by Kit Ong
    It has always been a real pain to incorporate extensive SharePoint Unit Testing and Load Testing in a project, could Visual Studio 2012 finally make this easier? It certaining looks like it, here's a brief overview on SharePoint support in Visual Studio 2012. Load testing – We now support load testing for SharePoint out of the box. This is more involved than you might imagine due to how dynamic SharePoint is. You can’t just record a script and play it back – it won’t work because SharePoint generates and expects dynamic data (like GUIDs). We’ve built the extensions to our load testing solution to parse the dynamic SharePoint data and include it appropriately in subsequent requests. So now you can record a script and play it back and we will dynamically adjust it to match what SharePoint expects.Unit testing – One of the big problems with unit testing SharePoint is that most code requires SharePoint to be running and trying to run tests against a live SharePoint instance is a pain. So we’ve built a SharePoint “emulator” using our new VS 2012 Fakes & Stubs capability. This will make unit testing of SharePoint components WAY easier.Read more in the link belowhttp://blogs.msdn.com/b/bharry/archive/2012/09/12/visual-studio-update-this-fall.aspx

  • Multiple Condition Coverage Testing

    - by David Relihan
    Hi Folks, When using the White Box method of testing called Multiple Condition Coverage, do we take all conditional statements or just the ones with multiple conditions? Now maybe the clues in the name but I'm not sure. So if I have the following method void someMethod() { if(a && b && (c || (d && e)) ) //Conditional A { } if(z && q) // Conditional B { } } Do I generate the truth table for just "Conditional A", or do I also do Conditional B? Thanks,

  • Automate Testing on future only items business rules

    - by Titan
    I currently have a business object with a validation business rule, which is it can only be created for the future, tomorrow onwards, and I cannot create new items for today. I have a process, which runs the non-future business objects through some steps.. Because I have to set things up today, and test tomorrow, and when it fails, I can only create a new object tomorrow and test the following day. Are there any easy ways to automate this process in any testing frameworks? I think our testers are using the visual studio 2010 test manager. How do you guys manage situations like this? Cheers

  • What is the objective of unit testing?

    - by user728750
    I've been working with C# for the last 2 years, and I've never done any unit testing. I just need to know what the objective of unit testing is. What kind of results do we expect from unit testing? Is code quality checked by unit testing? In my view, unit testing is the job of testers; if that is true, then as a developer why would I need to write test code if the tester does the unit testing? Why should I write extra code for testing? Do I need to maintain a separate copy of a project for unit testing?

  • Link between tests and user stories

    - by Sardathrion
    I have not see these links explicitly stated in the Agile literature I have read. So, I was wondering if this approach was correct: Let a story be defined as "In order to [RESULT], [ROLE] needs to [ACTION]" then RESULT generates system tests. ROLE generates acceptance tests. ACTION generates component and unit tests. Where the definitions are the ones used in xUnit Patterns which to be fair are fairly standard. Is this a correct interpretation or did I misunderstand something?

  • What is the difference between debugging and testing?

    - by persepolis
    Introduction To Software Testing (Ammann & Offutt) mentions on p.32 a 5-level testing maturity model: Level 0 There’s no difference between testing and debugging. Level 1 The purpose of testing is to show that the software works. Level 2 The purpose of testing is to show that the software doesn’t work. Level 3 The purpose of testing is not to prove anything specific, but to reduce the risk of using the software. Level 4 Testing is a mental discipline that helps all IT professionals develop higher quality software. Although they don't go into much further detail. What are the differences between debugging and testing?

I try to test the login like this require 'test_helper' class UserFlowsTest < ActionController::IntegrationTest fixtures :all # Replace this with your real tests. test "login and browse" do https! get "/users/new" assert_response :success post "/user_sessions", :email => '[email protected]', :password => 'aaaa' follow_redirect! assert_equal root_path, path end end I use authlogic gem in my rails app. What is wrong with this test? It breaks at 'follow_redirect!' saying it is not a redirection but login through a browser works. Thx!

  • Reminder: Premier Support for 10gR2 10.2.0.4 Database ends July 2010

    - by Steven Chan
    Regular readers know that Premier Support for the Oracle 10gR2 Database ends in July 2010, a scant few months from now.  What does that mean for E-Business Suite environments running on this database?The Oracle E-Business Suite is comprised of products like Financials, Supply Chain, Procurement, and so on.  Support windows for the E-Business Suite and these associated applications products are listed here:Oracle Lifetime Support > "Lifetime Support Policy: Oracle Applications" (PDF)The Oracle E-Business Suite can run on a variety of database releases, including 10gR2, 11gR1, and 11gR2.  Support windows for database releases are listed here:Oracle Lifetime Support > "Lifetime Support Policy: Oracle Technology Products" (PDF)Looking at those two documents together, you'll see that:Premier Support for Oracle E-Business Suite Release 11i ends on November 30, 2010Premier Support for Oracle E-Business Suite Release 12 ends on January 31, 2012Premier Support for Oracle E-Business Suite Release 12.1 ends on May 31, 2014Premier Support for Oracle Database 10.2 (a.k.a. 10gR2) ends on July 31, 2010[Note: These are the Premier Support dates as of today.  If you've arrived at this article in the future via a search engine, you must check the latest dates in the Lifetime Support Policy documents above; these dates are subject to change.]It's a bit hard to read, thanks to the layout restrictions of this blog, but the following diagram shows the Premier and Extended Support windows for the last four major database releases certified with Apps 11i:Do the EBS Premier Support dates trump the 10gR2 DB date?No.  Each of the support policies apply individually to your combined EBS + DB configuration.  The support dates for a given EBS release don't override the Database support policy.

  • Multi-tenancy - single database vs multiple database

    - by RichardW1001
    We have a number of clients, whose systems share some functionality, but also have quite a degree of diversity. The number of clients is growing - always a healthy thing! - and the diversity between their businesses is also increasing. At present there is a single ASP.Net (Web Forms) Web Site (as opposed to web project), which has sub-folders for each tenant, with that tenant's non-standard pages. There is a separate model project, which deals with database access and business logic. Which is preferable - and most importantly, why - between having (a) 1 database per client, with only the features associated with that client; or (b) a single database shared by all clients, where only a subset of tables are used by any one client. The main concerns within the business are over: maintenance of multiple assets - backups, version control and the like promoting re-use as much as possible How would you ensure these concerns are addressed, which solution is preferable, and why? (I have been also compiling responses to similar questions)

  • Functional testing in the verification

    - by user970696
    Yesterday my question How come verification does not include actual testing? created a lot of controversy, yet did not reveal the answer for related and very important question: does black box functional testing done by testers belong to verification or validation? ISO 12207:12208 here mentiones testing explicitly only as a validation activity, however, it speaks about validation of requirements of the intended use. For me its more high level, like UAT test cases written by business users ISO mentioned above does not mention any specific verification (7.2.4.3.2)except for Requirement verification, Design verification, Document and Code & Integration verification. The last two can be probably thought as unit and integrated testing. But where is then the regular testing done by testers at the end of the phase? The book I mentioned in the original question mentiones that verification is done by static techniques, yet on the V model graph it describes System testing against high level description as a verification, mentioning it includes all kinds of testing like functional, load etc. In the IEEE standard for V&V, you can read this: Even though the tests and evaluations are not part of the V&V processes, the techniques described in this standard may be useful in performing them. So that is different than in ISO, where validation mentiones testing as the activity. Not to mention a lot of contradicting information on the net. I would really appreciate a reference to e.g. a standard in the answer or explanation of what I missed in the ISO. For me, I am unable to tell where the testers work belong.
