Problems of LabVIEW with Test Unit under lvoop

Hello

I try now provided with LV2012 with a LVOOP code Unit Test infrastructure but seem to be a few problems.

I have built a unit test for a base class in the attached draft who is the source of class (it is another class in the project as it is an example of a method for recovering, but it is not used in the unit test). My problem is that I get results that fail for one of my tests, when I think they have to work.

Basically, the unit test is configured as follows

Case 1) test the VI without installation VI and ensure proper operation default values

Case 2) test VI by setting specific values in the test in VI of disassembly and also check the single release of "Source Method.vi" configuration VI

Case 3) Test of the VI with the VI of installation using the default values and confirm them through the VI of disassembly

When running case 2 fails and indicates that disassembly of the VI return values by default not those fed to the installation VI. I don't see why.

As per

Any suggestions?

All the best

David

Hi David,

The behavior you describe is planned. When you first call the 'Source_Method.vi' by using the 'SourceAccess Unit Test Manual.vi", the"Unit Test Manual.vi SourceAccess' creates and instance of the "Source_Method.vi". In this specific case of the VI it will boot with the default values but will then retain the values passed by the "Unit Test Manual.vi SourceAccess' until the project we closed, or specifically tell you to reset defaults. Whenever she is called by 'SourceAccess Unit Test Manual.vi' it will access this instance of it. If another instance of the "Source_Method.vi" was created by another parent it would be initialized with their default values, until crushed by the top-level VI calling. Then would he behave exactly as the instance created by the "Unit Test Manual.vi SourceAccess". Whatever your type typedef and its configuration, as long as everything is connected correctly, this should be the expected behavior when you configure things through object-oriented programming in LabVIEW.

I hope this information is useful to your application. If you want to see a LabVIEW example that demonstrates this behavior, you should consider referring to parts of the ReferenceObject.lvproj. It is found by searching in the example finder LabVIEW object-oriented. This is accessible via

  • Problem running scripts with Oracle Test Manager (MTM)

    Hi all!

    I am facing a problem to run any test in OTM.
    I'm adding scripts that I created in OpenScript (and which take place in perfect inside) but running in Test Manager fails.
    To be more precise, I even created a very simple script for the case in which I open the browser, navigate to an existing page (for example www.fmstocks.com/fmstocks - like documentation for example) and then I close the browser.
    What is happening is that the test fails after a few seconds. In the report results, summary of Script, it there a failure result to give Total iteration:

    + Object "/ web:window[@index='0" [or @title =' subject: empty '] "+."
    + did not action: +.
    + < name of message = "Navigate" > < parameter WindowIndex = '0' > +.
    + < / parameter > +.
    + < parameter Url = "http://www.fmstocks.com/fmstocks" > +.
    + < / parameter > < / Message > +.

    This is the same result that I get in any script I run (with different Url of course).
    I tried to alternate some settings in the Manager (Tools-> system) systems and change my OTM server, I've seen in a thread. I found that if I write as a user name and password to my windows or my OTM username and password (instead of JMSAdmin I see is the default user name) when I run the test simply never stops!
    To be clear, I just started using OATS. All the foregoing is done with the default settings after installation. OpenScript works fine but I need OTM so that I can perform several set of test scripts.

    Any help is appreciated!

    Hello
    You must first set back the remote system OTM to JMSAdmin / the_pwd_you_supplied_during_installation
    Then, you must stop the Windows Service called "Oracle Application Testing Suite Agent Service" and put it in the manual.
    Then, you start the agent from the command line
    C:\OracleATS\agentmanager\bin\AgentManagerService.exe - c C:\OracleATS\agentmanager\bin\AgentManagerService.conf (something like that according to the installation path).

    Let us know if it is ok then.

  • Install the engine 6.1 enforcement (or compatible) labview with the labview 2011

    I installed a Labveiw 2011 trial version in order to check for potential problems to upgrade, I get if I decide to spend labveiw 6.1. Well, needless to say, there has been a lot. This is as expected because I have not updated labview for many years. I'm still not under any pressure to update; However, I want to in order to get help and make sure that I have no problem of compatibility with new equipment purchases. I was able to solve most of my problems of compatibility with code simple and other corrections. However, twice now I ran into an error at the launch of labview executeables compiled by two different manufacturers. The equipment I use is not yet old... maybe a year or two. When I run labview executables for the device on a PC that has the trial period 2011 installed labview under control, I get an error message saying something like "this requires a motor enforcement 6.1 (or compatible) of Labview. I tried to download and install the labivew engine 6.1 but I can't install this engine on a PC that has labview installed 2011. Can someone explain how I run these executables under labview 2011. I can't imagine that these executables were developed using 6.1 as this equipment is not yet a year old now.

    You should be able to have a number any time installed and 2011. I have several versions back to 7.0. I asked what exactly happens when you try to install it.

    Have you tried 2011 withdrawal, execution 6.1 installation and then installation of 2011?

  • Problems of network with 715W

    For months (seems like years?) I had to power cycle regularly my printer, the PC and the modem/router to restore network connectivity.  More recently (now) connectivity is dead, even until I can't connect using a USB cable.  If I try to print a page of test via a USB port, it goes through the motions, pulling a page from the paper tray, abruptly resets and get the blank page on the output tray.  I tried without success with several resets of the router, different channels, power levels, etc.

    Anyubody other similar problems?  Of course, I had also just replace my black and purchased 2 new black cartridge and a color cartridge to avoid missing (victimized by this one at Christmas while they were not in stock!)

    After spending over an hour on the phone with Dell, call of the Canada, getting bounced to half a dozen different representatives in the United States and then back to the Canada even once, he ended it would cost more than a little troubleshooting only so buy a new printer (not DELL).  I managed to get a RA number to be able to return the cartridges, that I just bought.

    Then I called my provider I had problems last week with my network which I think might be related.  After about 15 minutes with them, they found where a framework had been modified caused place ended my problems.  Even if they are not 'officially' supporting printers, he worked through the configuration with me and you have my printer works again 100%.

  • vRealize 7 - NSX Automation deployments fail due to problems of certificate with vRealize Orchestrator

    Hello community,

    After you have installed the latest version of vRA, vRO, and NSX I run questions when you apply components that use components of the NSX. First of all: details of the version:

    -vRA: 7.0.0 (build 3292778)

    -vRO: 7.0.0.16989 (build 331003)

    -NSX: 6.2.1 (build 3300239)

    vRO plugin versions are delivered with the vRO version listed above with the exception of the plugin NSX, which has been updated to the latest version (1.0.3 published on 17.12.15).

    In the configured tenant vRO is configured as endpoint. I can check the data collection is running and working. I can see the plugin NSX for vRO runs the workflow 'create endpoint NSX' from time to time using the configured user of vRA VRO.

    In the configured tenant vRO is thus configured as server default for ASD vRO. Connection test is successful. When you save the config I'm prompted to approve the vRO certificate, which I confirm. Note that the thumbprint specified matches the footprint of the vRO certificate that I get during the visit of the vRO system on https://vro:8281. I am able to navigate the vRO vRA designer workflows, therefore: connection seems established.

    Within vRO the vRA COFFEE and plug-ins IAAS have been saved successfully. I am able to browse the inventory of plugin for both plugins.

    To solve the problem, I created a new unified plan within the design section of vRA with the following configuration:

    -Transport box: my area of transport configured NSX (checked: manual creation on this area using NSX works very well)

    -Routed res pol. Bridge: my reference for the dash cluster to use Pol

    -The only component dragged to canvas is a 'network and safety'-> 'On-Demand NAT Network' that uses a profile preset 1-to-many network as is "Parent network profile" without manual modification.

    -Note that, although there is a plan very simple example to illustrate the problem, it happens with any model that I have set up if any component is confgured requiring the NSX plugin for vRO.

    "Whenever I ask this plan, the request fails with the error message:" ","application [fa1e0689-0d06-4308-a914-e498c0d1fd99]: 404 not found "

    Looking in vCenter, NSX and vRO I can check that nothing is really trigged when you ask for the action plan.

    Consider the vRA /storage/log/vmware/vcac/catalina.log becomes very visible:

    com.vmware.vcac.iaas.vco.network.helper.VcoEndpointSelector.isEndpointAlive:88 -
    vRealize Orchestrator endpoint with url [https://s00-vro.my.domain:8281/vco] is not alive. 
    Exception message:> [Host name 's00-vro.my.domain' does not match the certificate subject provided by the peer (CN=s00-vro.my.domain, OU=VMware, O=My Company, C=DE)]
    
    com.vmware.vcac.iaas.vco.network.helper.VcoEndpointSelector.getFirstAliveEndpointByPriority:200
    - vRealize Orchestrator endpoint [https://s00-vro.my.domain:8281/vco] with priority 1 is not alive. Skipping.
    
    org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolv
    er.logException:189 - Handler execution resulted in exception: Endpoint not found. There are no vRealize Orchestrator endpoints that are alive.
    
    com.vmware.vcac.platform.service.rest.resolver.ApplicationExceptionHandler.handleHttpStatusCodeException:673 - 404 Not Found
    org.springframework.web.client.HttpClientErrorException: 404 Not Found
    ...
    ...
    ...
    
    

    Please note that I double checked the certificate. This is a self-signed certificate created using the 7.0 vRO new control panel, the one I get when you go to https://vro:8281. It is valid and the object (issed to CN) matches perfectly the hostname entered the ASD and endpoint configuration in the vRA. It is separable and time on all components of the server is in sync with the use NTP.

    Now, I even re-generated certificate and re-registered and rebooted all the components, but while I can see that the certificate has been updated all components I always get the same question.

    Never had this problem with the previous version of the NSX / vRA / vRO. I checked the documentation if nothing has changed here, but did not find what I'm doing wrong. Anythimg I'm missing here? Any bug?

    OK, this seems to be the issue. So put atleast to previous day since version ofvRO (cannot check if it's true for charges vRO 7 installs as well but it is probably) vRO 'control center' will generate certificates based SHA1 vRA love not for actions that use the endpoint in the vRA vRO. ASD seems to work without these problems.

    Sidenote: VRO upgraded installs will also come with SHA1 based CERT if they use a self-signed cert created by vRO. However: you would think that it is sufficient to recreate the cert using the control center. But it turns out it isn't, because it will generate a (new) based SHA1 cert.

    What I did to solve the problem:

    1. create a vRO SSH2 based certificate without the cert extensions, similar to the one that ships with built-in vRA vRO. I tend to use xCA for these jobs, but openSSL will do as well. The exact format required for the certificate of vRO is not documented, but I can make sure you need it like this: PEM certificate in key private and public including format PKCS #1, formatted as follows:

    -----BEGIN RSA PRIVATE KEY-----
    (Your private Key: your_vro_server.key)
    -----END RSA PRIVATE KEY-----
    -----BEGIN CERTIFICATE-----
    (Your primary certificate: your_vro_server.crt)
    -----END CERTIFICATE-----
    -----BEGIN CERTIFICATE-----
    (Your intermediate certificate: intermed.crt)
    -----END CERTIFICATE-----
    -----BEGIN CERTIFICATE-----
    (Your root certificate: root.crt)
    -----END CERTIFICATE-----
    

    I had problems when I used the key extensions so I would say you don't use and don't create a very basic cert without extensions V3, as indicated on the right of the image to my last post (ideally, you want to have a cert with the same properties as the cert is used by the device of integrated vRO vRA unless of course different CN) etc.).

    2. use the vRO control center located at https://your-externa-vro:8283 / vco-controlcenter / #/ and move to--> Orchestrator Server SSL certificate certificates. Use the action to import to import your PEM cert. It should tell you that you need to restart your device vRO. Then RESTART the device (for not just restart the service, this seems not be sufficient).

    3 al ' vRA remove the Endpoint vRO everywhere wherever it has been configured. Also, I removed the vRO to the ASD config just to make sure that nothings left.

    4 reboot the vRA power (IAAS can be left as what). I needed to do this because I have seen that the keystore at some point would keep beeing crushed by CERT vRA (?), I deleted it (AND I checked that they are deleted) reappears in the keystore after a while. After a reboot, the problem was gone, the keystore was clean.

    5. Add the configuration of endpoint and ASD vRO. Accept the certificate.

    6. the works.

    Therefore, while I have no more time to solve the problems more than I guess the problem is the SHA1 function certificate generated by the device of vRO. The internal unit is equipped with a SHA2 based cert that works and after that change the external device SHA1 cert in a basic cert SHA2 all works.

  • Engineering problems the surrogate with Unique key primary key

    SDDM 3.3.0.747 with 2 problems (at least so far).  I hope that the problem comes from this recruit SDDM and I forgot a setting. PROBLEM 1 I don't want to start a religious debate on substitution vs natural keys but I'm having a problem correctly both the logic model of engineering.  I'm a rookie when it comes to SDDM but have many years of experience with the Designer. By default, only I wish I had a natural UID (UK) and a surrogate mother based on a primary key UID (PK) which is used for foreign keys.  The problem I have with engineering is I can successfully engineer the substitute PK, engineer of the FK with the PK, but cannot get the unique key to contain surrogate keys in the child table.  If I check the identification property in relationships, the PK columns and the UK are included in the child PK and the United Kingdom contains no columns. The installation program, I've defined two reference entities, PROBABILITY and GRAVITY with unique keys natural defined.  I also have a child entity RISK_ASSESMENT with links to entities of the PROBABILITY and SEVERITY and both have the "use surrogate keys:": check box selected.  The unique key of the entity RISK_ASSESMENT includes links to PROBILITY and GRAVITY.  None of the entities have a PK or replacement of the defined keys and they all have the checkbox "Create a surrogate key" checked.  In addition the following preferences are defined: Data Modeling/model/logic NO checked - use and the first Unique key as primary key value NOT checked - name - Keep under the name of the from attribute Checked - entity carrier to create controlled key - use surrogate PROBLEM 2 key relationship when the foreign key columns are engineered I want names have a prefix 'FK_"but they don't.  Models are defined as follows: Data Modeler/assignment of Standard/Templates Foreign Key name: FK_ {children} {parent} foreign key column: engineer FK_ {Ref column} relational model/General checked Options - translation name Marcus Bacon apply

    Once more, I designed without removing anything and still no FK to the United Kingdom of the child.

    There is a synchronization problem in DM 4.0 EA1. This will be fixed for the production version.

  • Problems of wireless with my Satellite A505

    Hello people,

    I have a Satellite A505 which uses a Realtek RTL8191SE wireless network card. Recently, I had connectivity problems with my home router. This configuration used to work perfectly, but recently, I had a problem where I won't be able to connect to my router wireless access point. Reset the adapter does not solve the problem, or don't restart.

    I found that my router reboot solves the problem, I am able to login after the reboot of the router. I have not had this problem on any of the other devices or laptops in my house and never had this problem until last month. I tried to do a factory reset on my router in order to ensure that some recent changes in our setup of the router were not to blame, but the problem persists even with a clean slate.

    Ideas for what to do?

    Thank you!

    Hello

    >... and never had this problem until the last month or more
    Do you use WLAN driver from Toshiba support page?
    I ask this question because I noticed that under Win7 driver for this wireless network card is offered as optional update. Maybe this update is installed, and now you have this problem.
    If possible, try to roll back OS a few weeks back and check if the problem persists.

  • Beginner question absolute to the Labview with GPIB connection device

    Hi all

    Firstly, sorry if my question is already posted, but I tried searching with nothing doesn't.

    My situation: I have a HP digital osciloscope, a HP 54602 B using the GPIB and trial version of labview 8.6. Now, I want to communicate with her from labview. The big question is: how? Before that I used only labview with NI DAQ card and serial port for communications of the instrument.

    the detailed question

    1 is it important (to programming in labview later) what GPIB interface that I use in my computer? Must be of OR? I still have no interface right now.

    2. I ran a search on the osciloscope Web site of NOR and find an instrument driver in:

    http://sine.NI.com/apps/UTF8/niid_web_display.download_page?p_id_guid=E3B19B3E93F7659CE034080020E748...

    . How do they come?

    3. I know there are a few examples for the GPIB, but since I do not have the interface, I can't try it. Is it possible to simulate instruments GPIB?

    Thanks for all your help and assistance

    Hi opiq;

    Welcome to the world of instrument in LabVIEW Control!  I'll try and answer your questions one-at-a-time:

    1. N ° from a point of view of LabVIEW, you can use any interface supported by VISA and your instrument bus.  This includes (but is not limited to) boards of NOR-GPIB, 3rd-party GPIB, USB, LAN, LXI, VXI, PXI, etc..  Of course, if you do not have a GPIB interface, I would recommend a NEITHER - this is the safest way to get the experience 'it works '.  I tend to use an adapter USB GPIB (DISCLAIMER - I work for the OR).
    2. You have two options for installing the device driver.  "" The simplest is in LabVIEW to select Tools "Instrumentation" instrument Drivers find... and use our instrument driver search tool which will be step helps you locate, by downloading and installing the driver.  The other option is to download the zip file, unzip it in \National Instruments\LabVIEW 8.6\instr.lib and restart LabVIEW.  So if you look in your palette of instrumentation, you should see the driver listed under instrument drivers.  The pilot will include some examples of the use of the driver (are all certified instrument drivers).

      In fact, I would recommend this driver rather than that you connected.  It is a more modern design and install examples in the viewfinder of the example ("Help" find examples...).

      Here's a video of the above process (for a different instrument, but the process is the same)

    3. Unfortunately, there is not an easy way to simulate this instrument.  I would just recommend familiarizing yourself with the examples before acquiring a GPIB interface.
  • Problems using the local test on a Mac server

    I defined a local test for my website server: connect you using Local/network; file server: / Users /... / FPPATesting /; Web URL: http://localhost/FPPATesting/; For model server: No.  The site is hosted on a server of InMotion.

    I see that my local server folder was automatically filled with site files, but there are many missing, although the index.shtml file is there. If I drag the index.shtml file in the test folder in the field URL of Safari, it shows pretty much as it should, except that my Include files were not loaded. the Include files are in the folder test, but they aren't repeated. I get the same result if I choose Preview in Safari. And in this case, the files are all taken from the test folder; If the test server seems to be recognized by Dreamweaver.

    Curiously, if in the test folder, I open the file index.shtml, in Dreamweaver, Live View in Dreamweaver displays a seemingly complete site - almost. It is not complete because there not all the image files for the site. But the Include files have been included.

    So my problem is from my test server. I thought that call for a preview in one of the browsers show me the full site. Would it because I chose a server model "None"? I didn't know what else to use, as I am not including any content database. What should I do now?

    This can help working with server-side includes in Dreamweaver.
