  • Question about Linux Device Drivers.

    - by smwikipedia
    I have just installed the Xubuntu. My box runs quite slower than before when installed with a Win7. I am wondering if I am missing some device drivers. I can use gnome-device-manager to list my devices. In the device list view, I saw several blue question mark on the left side of devices. Based on my windows experience, the question mark should indicate the device is not properly configured. Is it the same with gnome-device-manager? And most importantly, how could I know for sure whether or not the corresponding device drivers have been installed? Many thanks.

  • Android - modes of connectivity, device identification and device inter-communication?

    - by MalcomTucker
    Can someone explain a couple of very simple concepts to me - I'm interested in mobile devices running android and how they are identified over networks. Some scenarios: Device is connected over WiFi - presumably the device has a standard IP address as with any host and can communicate with any other android host over TCP/IP (assuming it knows the participating device's IP? Device is connected over bluetooth - how are devices identified in this case? Device is connected over mobile operator's network - this is the one I'm interested in and confused by - is there anyway for two or more devices to discover each other and communicate via the mobile operator's network? How does a device communicate with a backend server in this scenario? In other words, how do apps and devices communicate when not connected to a WiFi network? Thanks for any advice..

  • Should a developer write their own test plan for Q/A?

    - by Mat Nadrofsky
    Who writes the test plans in your shop? Who should write them? I realize developers (like me) regularly do their own unit testing whilst developing and in some cases even their own Q/A depending on the size of the shop and the nature of the business, but in a big software shop with a full development team and Q/A team, who should be writing those official "my changes are done now" test plans? Soon, we'll be bringing on another Q/A member to our development team. My question is, going forward, is it a good practice to get your developers to write their own test plans? Something tells me that part of that might make sense but another part might not... What I like about that: Developer is very familiar with the changes made, thus it's easy to produce a document... What I don't like about that: Developer knows how it's supposed to work and might write a test plan that caters to this without knowing it. So, with the above in mind, what is the general stance on this topic? I'm of course already reading books like the Mythical Man-Month, Code Complete and a few others which really do help, but I'd like to get some input from the group as well.

  • How can I use a pre-populated core data DB on my device.

    - by KingAndrew
    Hi all, I have developed my app using core data. It works fine in the simulator. When I deploy it to the device the DB is empty. It is 49k where it should be 484k. Basically it is not populated. Since I don't write to the DB when the app is running I need to provide a populated DB to the App. So I copied the populated DB from the simulator to resources and then deploy. Still no luck. the populated DB is in MyApp.app and the AppDelegate is reading from the Documents directory. How do I either get it in the documents directory or get the app delegate to look in the app? Thanks in advance, Andrew

  • Device being used by VxVM

    If you are using vxvm, you may have issues when you try to unconfigure a disk root@techsupport2 # cfgadm -c unconfigure c1::dsk/c1t3d0cfgadm: Component system is busy, try again: failed to offline:     Resource             Information       ----------------       -------------------------/dev/dsk/c1t3d0   Device being used by VxVM“cfgadm unconfigure” command fails here.The way to resolve this is to disable the disks path from DMP control. Since there is only one path to this disk, the “-f” (for force) option needs to be used:root@techsupport2 # vxdmpadm -f disable path=c1t3d0s2root@techsupport2 # vxdmpadm getsubpaths NAME         STATE[A]   PATH-TYPE[M] DMPNODENAME  ENCLR-NAME   CTLR   ATTRS================================================================================c1t6d0       ENABLED(A)   -          disk_0       disk         c1       -c1t3d0       DISABLED(M)   -          disk_1       disk         c1       -c1t0d0s2     ENABLED(A)   -          disk_2       disk         c1       -c1t1d0       ENABLED(A)   -          disk_3       disk         c1       -c3t47d0      ENABLED(A)   -          sun35100_0   sun35100     c3       -c3t47d1      ENABLED(A)   -          sun35100_1   sun35100     c3       -c3t47d2s2    ENABLED(A)   -          sun35100_2   sun35100     c3       -c3t47d3s2    ENABLED(A)   -          sun35100_3   sun35100     c3       -You can see the path now disabled from DMP.root@techsupport2 # cfgadm -c unconfigure c1::dsk/c1t3d0Now you can unconfigure the disk

  • Radeon Mobility HD 5470 Not Working on Ubuntu 10.10

    - by Promather
    I recently bought a new HP DV6-3118SA laptop, but I am having a very discouraging problem with the graphics card. The graphics card is Radeon Mobility HD 5470. It doesn't install by default, but I do get some message suggesting to install the driver. If I install that driver, the next time I reboot, the screen goes blank and that's it! The same happens if I install the proprietary driver (fglrx) from ATI website. Could you please help me with this?

  • Splitting a test to a set of smaller tests

    - by mkorpela
    I want to be able to split a big test to smaller tests so that when the smaller tests pass they imply that the big test would also pass (so there is no reason to run the original big test). I want to do this because smaller tests usually take less time, less effort and are less fragile. I would like to know if there are test design patterns or verification tools that can help me to achieve this test splitting in a robust way. I fear that the connection between the smaller tests and the original test is lost when someone changes something in the set of smaller tests. Another fear is that the set of smaller tests doesn't really cover the big test. An example of what I am aiming at: //Class under test class A { public void setB(B b){ this.b = b; } public Output process(Input i){ return b.process(doMyProcessing(i)); } private InputFromA doMyProcessing(Input i){ .. } .. } //Another class under test class B { public Output process(InputFromA i){ .. } .. } //The Big Test @Test public void theBigTest(){ A systemUnderTest = createSystemUnderTest(); // <-- expect that this is expensive Input i = createInput(); Output o = systemUnderTest.process(i); // <-- .. or expect that this is expensive assertEquals(o, expectedOutput()); } //The splitted tests @PartlyDefines("theBigTest") // <-- so something like this should come from the tool.. @Test public void smallerTest1(){ // this method is a bit too long but its just an example.. Input i = createInput(); InputFromA x = expectedInputFromA(); // this should be the same in both tests and it should be ensured somehow Output expected = expectedOutput(); // this should be the same in both tests and it should be ensured somehow B b = mock(B.class); when(b.process(x)).thenReturn(expected); A classUnderTest = createInstanceOfClassA(); classUnderTest.setB(b); Output o = classUnderTest.process(i); assertEquals(o, expected); verify(b).process(x); verifyNoMoreInteractions(b); } @PartlyDefines("theBigTest") // <-- so something like this should come from the tool.. @Test public void smallerTest2(){ InputFromA x = expectedInputFromA(); // this should be the same in both tests and it should be ensured somehow Output expected = expectedOutput(); // this should be the same in both tests and it should be ensured somehow B classUnderTest = createInstanceOfClassB(); Output o = classUnderTest.process(x); assertEquals(o, expected); }

  • Anyone have an XSL to convert Boost.Test XML logs to a presentable format?

    - by Stuart Lange
    I have some C++ projects running through cruisecontrol.net. As a part of the build process, we compile and run Boost.Test unit test suites. I have these configured to dump XML log files. While the format is similar to JUnit/NUnit, it's not quite the same (and lacks some information), so cruisecontrol.net is unable to pick them up. I am wondering if anyone has created (or knows of) an existing XSL transform that will convert Boost.Test results to JUnit/NUnit format, or alternatively, directly to a presentable (html) format. Thanks!

  • When using Microsoft Test Manager 2010 with SfTS, how do QA engineers know what tests they have to run?

    - by MADCookie
    We are moving our projects to TFS 2010 using the SfTS v3 (Scrum for Team System) template. We need to understand how Microsoft Test Manager is supposed to be used in this Scrum process. Specific scenario & question: The QA manager uses Test Manager to create Acceptance Test Work Items (WIs). These new WIs are created and "assigned to" him. The manager doesn't run all the tests, instead he wants to give that responsibility to his staff. How is a QA engineer supposed to know that he has tests to run? Everything says it is assigned to the manager.

  • Download and Try Out the New ‘Australis UI’ Test-Build of Firefox for Windows

    - by Asian Angel
    We have all been hearing about the upcoming changes to the UI in Firefox and now the first test build is finally available to try out. Mozilla software engineer Jared Wein has worked hard and put together an unofficial (at the moment) Australis UI build that you can download as a regular installer or as a portable in zip file format. Here is a closer look at the new tab setup in the Australis build. Notice that only the focused tab is non-transparent while the non-active tabs blend nicely into the background. Special Note: Our screenshots were taken in Windows 8, thus the slightly different looking (non-rounded) corners on the app window. The test build only works on Windows at the moment, but you can bet that Linux and MacOS builds are coming in the near future!

  • How Can I Test My Computer’s Power Supply?

    - by Jason Fitzpatrick
    You’re concerned your computer troubles stem from a failing (or outright fried) power supply unit. How can you test the unit to be sure that it’s the source of your hardware headaches? Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. The Question SuperUser reader Sam Hoice has some PSU concerns: My computer powered off the other day on its own, and now when I push the power button, nothing happens. My assumption would naturally be that the power supply is done (possibly well done) but is there any good way to test this before I buy a new one? How can Sam test things without damaging his current computer or other hardware?   The Answer SuperUser contributor Grant writes: Unplug the power supply from any of the components inside the computer (or just remove it from the computer completely). USE CAUTION HERE (Though you’d only be shocked with a max of 24 volts) Plug the power supply into the wall. Find the big 24-ish pin connector that connects to the motherboard. Connect the GREEN wire with the adjacent BLACK wire. The power supply’s fan should start up. If it doesn’t then it’s dead. If the fan starts up, then it could be the motherboard that’s dead. You can use a multimeter to check if there is power output from the power supply. Adrien offers a solution for readers who may not be comfortable jamming wires into their power supply unit’s MOBO connector: Most well-stocked geek-stores sell a “power-supply tester” that has all the appropriate connectors to plug each part of your PSU into, with spiffy LEDs indicating status of the various rails, connectors for IDE/SATA/floppy power cables, etc. They run ~$20 US. With a little careful shopping you can even find a highly-rated PSU tester for a measly $6. Have something to add to the explanation? Sound off in the the comments.

  • No device file for partition on logical volume (Linux LVM)

    - by Brian
    I created a logical volume (scandata) containing a single ext3 partition. It is the only logical volume in its volume group (case4t). Said volume group is comprised by 3 physical volumes, which are three primary partitions on a single block device (/dev/sdb). When I created it, I could mount the partition via the block device /dev/mapper/case4t-scandatap1. Since last reboot the aforementioned block device file has disappeared. It may be of note -- I'm not sure -- that my superior (a college professor) had prompted this reboot by running sudo chmod -R [his name] /usr/bin, which obliterated all suid in its path, preventing the both of us from sudo-ing. That issue has been (temporarily) rectified via this operation. Now I'll cut the chatter and get started with the terminal dumps: $ sudo pvs; sudo vgs; sudo lvs Logging initialised at Sat Jan 8 11:42:34 2011 Set umask to 0077 Scanning for physical volume names PV VG Fmt Attr PSize PFree /dev/sdb1 case4t lvm2 a- 819.32G 0 /dev/sdb2 case4t lvm2 a- 866.40G 0 /dev/sdb3 case4t lvm2 a- 47.09G 0 Wiping internal VG cache Logging initialised at Sat Jan 8 11:42:34 2011 Set umask to 0077 Finding all volume groups Finding volume group "case4t" VG #PV #LV #SN Attr VSize VFree case4t 3 1 0 wz--n- 1.69T 0 Wiping internal VG cache Logging initialised at Sat Jan 8 11:42:34 2011 Set umask to 0077 Finding all logical volumes LV VG Attr LSize Origin Snap% Move Log Copy% Convert scandata case4t -wi-a- 1.69T Wiping internal VG cache $ sudo vgchange -a y Logging initialised at Sat Jan 8 11:43:14 2011 Set umask to 0077 Finding all volume groups Finding volume group "case4t" 1 logical volume(s) in volume group "case4t" already active 1 existing logical volume(s) in volume group "case4t" monitored Found volume group "case4t" Activated logical volumes in volume group "case4t" 1 logical volume(s) in volume group "case4t" now active Wiping internal VG cache $ ls /dev | grep case4t case4t $ ls /dev/mapper case4t-scandata control $ sudo fdisk -l /dev/case4t/scandata Disk /dev/case4t/scandata: 1860.5 GB, 1860584865792 bytes 255 heads, 63 sectors/track, 226203 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00049bf5 Device Boot Start End Blocks Id System /dev/case4t/scandata1 1 226203 1816975566 83 Linux $ sudo parted /dev/case4t/scandata print Model: Linux device-mapper (linear) (dm) Disk /dev/mapper/case4t-scandata: 1861GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 1861GB 1861GB primary ext3 $ sudo fdisk -l /dev/sdb Disk /dev/sdb: 1860.5 GB, 1860593254400 bytes 255 heads, 63 sectors/track, 226204 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000081 Device Boot Start End Blocks Id System /dev/sdb1 1 106955 859116006 83 Linux /dev/sdb2 113103 226204 908491815 83 Linux /dev/sdb3 106956 113102 49375777+ 83 Linux Partition table entries are not in disk order $ sudo parted /dev/sdb print Model: DELL PERC 6/i (scsi) Disk /dev/sdb: 1861GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 880GB 880GB primary reiserfs 3 880GB 930GB 50.6GB primary 2 930GB 1861GB 930GB primary I find it a bit strange that partition one above is said to be reiserfs, or if it matters -- it was previously reiserfs, but LVM recognizes it as a PV. To reiterate, neither /dev/mapper/case4t-scandatap1 (which I had used previously) nor /dev/case4t/scandata1 (as printed by fdisk) exists. And /dev/case4t/scandata (no partition number) cannot be mounted: $sudo mount -t ext3 /dev/case4t/scandata /mnt/new mount: wrong fs type, bad option, bad superblock on /dev/mapper/case4t-scandata, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so All I get on syslog is: [170059.538137] VFS: Can't find ext3 filesystem on dev dm-0. Thanks in advance for any help you can offer, Brian P.S. I am on Ubuntu GNU/Linux 2.6.28-11-server (Jaunty) (out of date, I know -- that's on the laundry list).

  • Test iPhone app on iPad mini?

    - by Devfly
    I have developed an iPhone app, right now I only need a device for testing. I have 300$, and two choices - second hand iPhone 4, or brand new iPad mini. The better choice obviously is the iPad, but is it sufficient for testing iPhone apps on? On the iPad, iPhone apps can run just fine in 2X mode, but are there any differences between the app performance on iPhone and iPad (except the chipset). Should I test my app on actual iPhone, or the iPad will suffice? My app is RSS reader, not some game, so I think everything will be fine with testing on iPad mini. If I buy the iPad I will find some friends iPhone 4/3gs running iOS 5.1 (because my app's deployment target is 5.1, and the iPad comes with 6.0), but of course I can't extensively test on this iPhone. Thank you!

  • Test driven vs Business requirements constant changing

    - by James Lin
    One of the new requirement of our dev team set by the CTO/CIO is to become test driven development, however I don't think the rest of the business is going to help because they have no sense of development life cycles, and requirements get changed all the time within a single sprint. Which gets me frustrated about wasting time writing 10 test cases and will become useless tomorrow. We have suggested setting up processes to dodge those requirement changes and educate the business about development life cycles. What if the business fails to get the idea? What would you do?

  • Uploading a file automatically for speed test?

    - by Abhi
    I am building a Web UI for a device for internet connection and one of the requirements in it is a speed test. I know the basic concept of how speed test works. A file is downloaded for a limited time then the same file is uploaded again and the speed is tracked at regular intervals. Downloading the file is not an issue, but how am I supposed to upload the file without the client knowing that the file is getting uploaded? I've read through a lot of documentation, but I'm still not able to get the answer to how I will upload the file from clients machine without asking him to select the file.

  • 4 Places To Find Up-To-Date Antivirus Test Results Online

    - by Chris Hoffman
    Do you know how effective your antivirus programs is? A variety of organizations regularly compare antivirus programs, throwing a large amount of malware samples at them, seeing how they perform, and ranking them in comparison to each other. It would be very time-consuming to test 30 different antivirus programs in virtual machines with a large amount of malware samples yourself, which is why these test results are so useful.

  • Make the JavaScript Test Pass

    Add code on the commented line: var f = function () { var value = // ??? return f.sum = (f.sum || 0) + value;} ... to make the following QUnit test pass: test("Running sum", function () { equals(f(3), 3); equals(f(3), 6); equals(f(4), 10); jQuery([1, 2, 3]).each(f); equals(f(0), 16); }); Possible Answer It's a goofy scenario, but one possible solution uses a technique you'll see frequently inside today's JavaScript libraries.
