  photo courtesy of mtoleric via Flickr If you want to test and deploy your applications much faster than you could before, take a look at these OTN resources. They won't disappoint. Developer Webinar: How to Test and Deploy Applications Faster - April 10 Our second developer webinar, conducted by engineers Eric Reid and Stephan Schneider, will focus on how the zones and ZFS filesystem in Oracle Solaris 11 can simplify your development environment. This is a cool topic because it will show you how to test and deploy apps in their likely real-world environments much quicker than you could before. April 10 at 9:00 am PT Video Interview: Tips for Developing Faster Applications with Oracle Solaris 11 Express We recorded this a while ago, and it talks about the Express version of Oracle Solaris 11, but most of it applies to the production release. George Drapeau, who manages a group of engineers whose sole mission is to help customers develop better, faster applications for Oracle Solaris, shares some tips and tricks for improving your applications. How ZFS and Zones create the perfect developer sandbox. What's the best way for a developer to use DTrace. How Crossbow's network bandwidth controls can improve an application's performance. To borrow the classic Ed Sullivan accolade, it's a "really good show." "White Paper: What's New For Application Developers Excellent in-depth analysis of exactly how the capabilities of Oracle Solaris 11 help you test and deploy applications faster. Covers the tools in Oracle Solaris Studio and what you can do with each of them, plus source code management, scripting, and shells. How to replicate your development, test, and production environments, and how to make sure your application runs as it should in those different environments. How to migrate Oracle Solaris 10 applications to Oracle Solaris 11. How to find and diagnose faults in your application. And lots, lots more. - Rick Website Newsletter Facebook Twitter

• Is your Xcode4 stable?

  - by Eonil

  I have upgraded to Xcode4, and I'm experiencing unbelievable situation. Xcode4 crashes per 5 minute. Incredibly slow. Almost impossible to use. Maybe the problem is my hardware configuration. I'm using MacBook Air 3rd with 2GB ram with SSD. It was just fine with Xcode3, but now, it consumes all of memory and crashes too often. Does your Xcode4 stable? If so, please let me know what's your hardware configuration. I want to know whether this problem is caused by hardware configuration or not to decide buy a new mac.

• Programming test for ASP.NET C# developer job - Opinions please!

  - by Indy

  Hi all, We are hiring a .NET C# developer and I have developed a technical test for the candidates to complete. They have an hour and it has two parts, some knowledge based questions covering asp.net, C# and SQL and a small practical test. I'd appreciate feedback on the test, is it sufficient to test the programmers ability? What would you change if anything? Part One. What the are events fired as part of the ASP.NET Page lifecycle. What interesting things can you do at each? How does ViewState work and why is it either useful or bad? What is a common way to create web services in ASP.NET 2.0? What is the GAC? What is boxing? What is a delegate? The C# keyword .int. maps to which .NET type? Explain the difference between a Stored Procedure and a Trigger? What is an OUTER Join? What is @@IDENTITY? Part Two: You are provided with the Northwind Database and the attached DB relationship diagram. Please create a page which provides users with the following functionality. You don’t need to be too concerned with the presentation detail of the page. Select a customer from a list, and see all the orders placed by that customer. For the same customer, find all their orders which are Beverages and the quantity is more than 5. I was aware of setting the right balance of difficulty on this as there is an hour's test. I was able to complete the practical test in under 30 mins using SQLDatasource and the query designer in visual studio and the test questions, I am looking to see how they approach it logically and whether they use the tools available. Many thanks!

• How to drastically improve code coverage?

  - by Peter Kofler

  I'm tasked with getting a legacy application under unit test. First some background about the application: It's a 600k LOC Java RCP code base with these major problems massive code duplication no encapsulation, most private data is accessible from outside, some of the business data also made singletons so it's not just changeable from outside but also from everywhere. no business model, business data is stored in Object[] and double[][], so no OO. There is a good regression test suite and an efficient QA team is testing and finding bugs. I know the techniques how to get it under test from classic books, e.g. Michael Feathers, but that's too slow. As there is a working regression test system I'm not afraid to aggressively refactor the system to allow unit tests to be written. How should I start to attack the problem to get some coverage quickly, so I'm able to show progress to management (and in fact to start earning from safety net of JUnit tests)? I do not want to employ tools to generate regression test suites, e.g. AgitarOne, because these tests do not test if something is correct.

• Mock Objects for Testing - Test Automation Engineer Perspective

  - by user9009

  Hello How often QA engineers are responsible for developing Mock Objects for Unit Testing. So dealing with Mock Objects is just developer job ?. The reason i ask is i'm interested in QA as my career and am learning tools like JUnit , TestNG and couple of frameworks. I just want to know until what level of unit testing is done by developer and from what point QA engineer takes over testing for better test coverage ? Thanks Edit : Based on the answers below am providing more details about what QA i was referring to . I'm interested in more of Test Automation rather than simple QA involved in record and play of script. So Test Automation engineers are responsible for developing frameworks ? or do they have a team of developers dedicated in Framework development ? Yes i was asking about usage of Mock Objects for testing from Test Automation engineer perspective.

• TDD: Write a separate test for object initialization or relying on other tests exercising it

  - by DXM

  This seems to be the common pattern that's emerging in some of the tests I've worked on lately. We have a class, and quite often this is legacy code whose design can't be easily altered, which has a bunch of member variables. There's some kind of "Initialize" or "Load" function which would put an object into a valid state. Only after it is initialized/loaded, are the members in the proper state so that other methods can be exercised. So when we start writing tests, first test is "TestLoad" and all we put in there is exercising initialization logic. Then we might add one (or few) TestLoadFailureXXX tests and those are definitely valuable. Then we start writing tests to verify other behaviors but all of them require the object to be loaded. So they all start by running exactly the same code as "TestLoad". So my question: Is TestLoad even necessary? Do you take it and let other tests simply exercise the loading? Or leave it so things are more explicit? I know that each unit test function should have no (or as little as possible) overlap with other test functions, but it seems like in cases of loading, this is unavoidable. And whether we like it or not, if something in the loading code breaks, we will end up with a whole test suite of failures. Is there another approach that I might be missing here? Thank you for the responses. It definitely makes sense that you want to see "InitializationTest" and if that fails you know where to start looking. In case it matters, this question is mostly about C++ and we use CppUnit framework. And now, thanks to sleske, I'll be constantly wishing that CppUnit supported test dependencies. Might have to hack something in one of these days :)

• Test-Driven Development with plain C: manage multiple modules

  - by Angelo

  I am new to test-driven development, but I'm loving it. There is, however, a main problem that prevents me from using it effectively. I work for embedded medical applications, plain C, with safety issues. Suppose you have module A that has a function A_function() that I want to test. This function call a function B_function, implemented in module B. I want to decouple the module so, as James Grenning teaches, I create a Mock module B that implements a mock version of B_function. However the day comes when I have to implement module B with the real version of B_function. Of course the two B_function can not live in the same executable, so I don't know how to have a unique "launcher" to test both modules. James Grenning way out is to replace, in module A, the call to B_function with a function pointer that can have the value of the mock or the real function according to the need. However I work in a team, and I can not justify this decision that would make no sense if it were not for the test, and no one asked me explicitly to use test-driven approach. Maybe the only way out is to generate different a executable for each module. Any smarter solution? Thank you

• Test Driven Development Code Order

  - by Bobby Kostadinov

  I am developing my first project using test driven development. I am using Zend Framework and PHPUnit. Currently my project is at 100% code coverage but I am not sure I understand in what order I am supposed to write my code. Am I supposed to write my test FIRST with what my objects are expected to do or write my objects and then test them? Ive been working on completing a controller/model and then writing at test for it but I am not sure this is what TDD is about? Any advice? For example, I wrote my Auth plugin and my Auth controller and tested that they work properly in my browser, and then I sat down to write the tests for them, which proved that there were some logical errors in the code that did work in the browser.

• If you should only have one assertion per test; how to test multiple inputs?

  - by speg

  I'm trying to build up some test cases, and have read that you should try and limit the number of assertions per test case. So my question is, what is the best way to go about testing a function w/ multiple inputs. For example, I have a function that parses a string from the user and returns the number of minutes. The string can be in the form "5w6h2d1m", where w, h, d, m correspond to the number of weeks, hours, days, and minutes. If I wanted to follow the '1 assertion per test rule' I'd have to make multiple tests for each variation of input? That seems silly so instead I just have something like: self.assertEqual(parse_date('5m'), 5) self.assertEqual(parse_date('5h'), 300) self.assertEqual(parse_date('5d') ,7200) self.assertEqual(parse_date('1d4h20m'), 1700) In the one test case. Is there a better way?

• Unittest test case only touches the file name

  - by Chen OT

  I was told that unittest is fast and the tests which touches DB, across network, and touches FileSystem are not unittest. In one of my testcases, its input are the file names (amount about 300~400) under a specific folder. Although these input are part of file system, the execution time of this test is very fast. Should I moved this test, which is fast but touches file system, to higher level test?

• RPi and Java Embedded GPIO: It all begins with hardware

  - by hinkmond

  So, you want to connect low-level peripherals (like blinky-blinky LEDs) to your Raspberry Pi and use Java Embedded technology to program it, do you? You sick foolish masochist. No, just kidding! That's awesome! You've come to the right place. I'll step you though it. And, as with many embedded projects, it all begins with hardware. So, the first thing to do is to get acquainted with the GPIO header on your RPi board. A "header" just means a thingy with a bunch of pins sticking up from it where you can connect wires. See the the red box outline in the photo. Now, there are many ways to connect to that header outlined by the red box in the photo (which the RPi folks call the P1 header). One way is to use a breakout kit like the one at Adafruit. But, we'll just use jumper wires in this example. So, to connect jumper wires to the header you need a map of where to connect which wire. That's why you need to study the pinout in the photo. That's your map for connecting wires. But, as with many things in life, it's not all that simple. RPi folks have made things a little tricky. There are two revisions of the P1 header pinout. One for older boards (RPi boards made before Sep 2012), which is called Revision 1. And, one for those fancy 512MB boards that were shipped after Sep 2012, which is called Revision 2. So, first make sure which board you have: either you have the Model A or B with 128MB or 256MB built before Sep 2012 and you need to look at the pinout for Rev. 1, or you have the Model B with 512MB and need to look at Rev. 2. That's all you need for now. More to come... Hinkmond

• What is the Ubuntu equivalent of the Windows programs Belarc or PC Wizard?

  - by CeltaWeb

  I provide technical support for several high schools in Spain and I have been building up a inventory of the schools machines. On the windows only computers I normally run PC Wizard to quickly get a good overview of the machines hardware, software and network settings. Is there an equivalent tool preferable with a GUI and an export option to html or pdf in Ubuntu. I have tried a few options such as: Gnomes gconf-editor hardinfo (GUI) lshw (CLI) I'm just looking for an all in one application that builds a detailed profile of the installed software, hardware and network setting of a particular machine. I have found Sysinfo which is quite good, it displays the most important hardware info and allows you to save it to a text file with a neat GUI. I'm still looking for a more complete solution but it's a good start.

• Audio is working, but the speaker test doesn't work

  - by Pacquo

  I've installed Ubuntu 12.04 LTS from a minimal cd on a netbook (Asus 1001 PXD). I've installed the ubuntu-desktop package using the --no-install-recommends option. Everything works fine, except the "sound test" for headphones or analog speakers. Clicking on the "test" buttons (front left and front right) I don't hear any sound. Despite this, the audio is working properly. I've checked the audio levels with alsamixer; I have also checked that the test sounds actually exist in /usr/share/sounds/alsa. I tried an installation of Ubuntu 12.04 LTS made with the desktop-cd, and in this case the speaker test works properly. I suppose, therefore, that the problem could depend on the lack of a package, but I have not identified which one.

• Innovative SPARC: Lighting a Fire Under Oracle's New Hardware Business

  - by Paulo Folgado

  "There's a certain level of things you can do with commercially available parts," says Oracle Executive Vice President Mike Splain. But, he notes, you can do so much more if you design the parts yourself. Mike Splain,EVP, OracleYou can, for example, design cryptographic accelerators into your microprocessors so customers can run their networks fully encrypted if they choose.Of course, it helps if you've already built multiple processing "cores" into those chips so they can handle all that encrypting and decrypting while still getting their other work done.System on a ChipAs the leader of Oracle Microelectronics, Mike knows how implementing clever innovations in silicon can give systems a real competitive advantage.The SPARC microprocessors that his team designed at Sun pioneered the concept of multiple cores several years ago, and the UltraSPARC T2 processor--the industry's first "system on a chip"--packs up to eight cores per chip, each running as many as eight threads at once. That's the most cores and threads of any general-purpose processor. Looking back, Mike points out that the real value of large enterprise-class servers was their ability to run a lot of very large applications in parallel."The beauty of our CMT [chip multi-threading] machines is you can get that same kind of parallel-processing capability at a much lower cost and in a much smaller footprint," he says.The Whole StackWhat has Mike excited these days is that suddenly the opportunity to innovate is much bigger as part of Oracle."In my group, we used to look up the software stack and say, 'We can do any innovation we want, provided the only thing we have to change is what's in the Solaris operating system'--or maybe Java," he says. "If we wanted to change things beyond that, we'd have to go outside the walls of Sun and we'd have to convince the vendors: 'You have to align with us, you have to test with us, you have to build for us, and then you'll reap the benefits.' Now we get access to the entire stack. We can look all the way through the stack and say, 'Okay, what would make the database go faster? What would make the middleware go faster?'"Changing the WorldMike and his microelectronics team also like the fact that Oracle is not just any software company. We're #1 in database, middleware, business intelligence, and more."We're like all the other engineers from Sun; we believe we can change the world, if we can just figure out how to get people to pay attention to us," he says. "Now there's a mechanism at Oracle--much more so than we ever had at Sun."He notes, too, that every innovation in SPARC has involved some combination of hardware and softwareoptimization."Take our cryptography framework, for example. Sure, we can accelerate rapidly, but the Solaris OS has to provide the right set of interfaces that applications can tap into," Mike says. "Same thing with our multicore architecture. We have to have software that can utilize all those threads and run in parallel." His engineers, he points out, have never been interested in producing chips that sell as mere components."Our chips are always designed to go into systems and be combined with various pieces of software," he says. "Our job is to enable the creation of systems."

• Virtual PC on Windows 7 - Hardware-assisted virtualization is disabled

  - by DLux

  I am running a Lenovo Thinkpad T61 with an Intel Core 2 Duo T7300 processor. When I run Virtual PC in Windows 7, I get the following error: Unable to start Windows Virtual PC because hardware-assisted virtualization is disabled. When running the Hardware-Assisted Virtualization Detection Tool from Microsoft says: Hardware-assited virtualization is not enabled on this computer. Now, in the BIOS, I do have virtualization enabled and according to Intel this processor supports Intel-VT. What am I missing here?

• Debian as USB hardware portable as possible

  - by James Mitch

  I have recent hardware, 64 bit, pae and so on. But I'd like to have my Debian installation on a USB HDD. Installing Debian to USB is solved. I used the i386 architecture image. But a pae kernel has been installed. I want to be able to travel with my USB HDD and therefore I want best possible hardware compatibility. My friends and family have sometimes older hardware, but always i386, just sometimes without 64 bit or pae. Never met someone with sparc or other architectures. What should I do to get non-pae kernel and maximum hardware compatibility?

• Blackberry device GPS hardware specs [closed]

  - by colemanm

  I'm looking to find out detailed specifications for the built-in GPS hardware in the Blackberry Bold and Curve devices (9000 and 8350). RIM's documentation includes just a rudimentary description of the specs, but I'm looking for things like the actual detailed hardware/chipset info so we can research the accuracy needs for some upcoming projects we have. Knowing simply "A-GPS support" isn't really good enough... Does anyone know of any resources for finding advanced specs for built-in Blackberry hardware?

• Interpreting and using the Asterisk "timing test" command

  - by zigg

  Timing is very important for certain kinds of applications in Asterisk. If DAHDI is the timing source, the dahdi_test command can be used to check the timing provided by the DAHDI kernel module. If dahdi_test returns exclusively measurements above 99.975%, the DAHDI timing source is generally considered good. Since Asterisk 1.6, new timing sources have become available, such as pthread and timerfd. The accuracy of these timing sources seems to be measurable with the Asterisk CLI timing test command: localhost*CLI> timing test Attempting to test a timer with 50 ticks per second. Using the 'timerfd' timing module for this test. It has been 1000 milliseconds, and we got 50 timer ticks My concern is that timing 50 ticks seems to be a considerably less stressful test than dahdi_test's 8192 samples in 8000 ms, particularly since just about every system I've tried it on, virtual or otherwise, can handle it. I can ask timing test to ramp it up to what I think are dahdi_test's standards: localhost*CLI> timing test 1024 Attempting to test a timer with 1024 ticks per second. Using the 'timerfd' timing module for this test. It has been 1000 milliseconds, and we got 1024 timer ticks This will indeed break down a bit depending on the system I'm using, usually with a decrease in timer ticks. But I'm not sure whether this is useful to stress it to this level. Is there authoritative guidance on using and interpreting the timing test command to insure that a given Asterisk system has a timing source that will work well?
