• LabVIEW Unit Test Framework: workaround for forbidden control characters label?

  Hello

  I am using Unit Test Framework of LabVIEW and he tells me that I am not allowed to use the unit as [Celsius] card in my labels of control:

  «Control's label may not contain the following items: \n, \r, tabs, table holders, name and decimal separators delimiters.»

  In the VI under test contain [] or /. »

  Rename these labels is a difficult option for me because the format of the units in brackets is on our company agreements.

  Can anyone think of a work around so that the test framework ignores these labels?

  Thank you

  Peter

  There was an exchange of views on these "Naming Conventions" a general consensus was arrived at, it became obvious that the best methods for the controls and indicators is to use short "Lables" and put to amplify the info in the caption showing the legend on the FP and not the Lable.

  for example

  "Temp".

  "Temperature [Celsius].

  This saves a lot of space BD when buldling / unbundling or using VI Server refs, always give the user all the information they need, and help displays the legend if there is one.  It even allows to change the default value (0) without messing up any type defs.

  In your case the Framwork UT would be happier if you have taken this approach.

• Error in Unit Test Framework: "the path of the VI test is not valid."

  I get this error on files lvtest for a few screws, it appears so when I click on the button "import values of VI.  The unit test framework correctly on some screws, but some work raise the error.  I tried to move and rename the files and of coarse checked the path of the file.  I'm open to suggestions, I'm starting to like what the Unit Test Framework is capable of, but this error becomes a problem for me.

  Thank you

  Hi John,.

  It seems that I do not receive the same error as you.  In the Advanced tab of .lvtest files, that you selected as the Configuration setting?  If you left it as default value, can you check to see if the orders/lights are selected in the connector pane?

  Not sure but maybe the problem is that your map name contains a space in there? I would try to rename "Mapping of DAC" in "DAC_Mapping".

• Control of canoe of unit tests in LabVIEW on ActiveX

  Hello

  I want to run the unit tests of canoe in LabVIEW using ActiveX.

  EnvVars and sysVars in canoe handling was not a big deal, and there are plenty of examples here.

  But the unit tests of handling is quite difficult. Canoe help file shows this way in the object hierarchy:

  I solved the problem with the help of vector Support. They sent me the following c# example:

              MApp CANoe.Application = new CANoe.Application ();
  
              CANoe.Configuration mConf = (CANoe.Configuration) mApp.Configuration;

              CANoe.TestEnvironments mTestEnvs = (CANoe.TestEnvironments) mTestSetup.TestEnvironments;
  
              CANoe.TestEnvironment mTestEnv = (CANoe.TestEnvironment) mTestEnvs [1]; Test environment (file *.tse)
  
              Console.WriteLine ("Name" + mTestEnv.Name);
  
  CANoe.TestSetupFolders mTestSetupFolders = (CANoe.TestSetupFolders) mTestEnv.Folders;
  
              CANoe.TSTestModule mTSTestmodule = (CANoe.TSTestModule) mTestEnv.TestModules [1];
  
              Console.WriteLine ("Name" + mTSTestmodule.Name);
  CANoe.TestSequence mTestSequence = (CANoe.TestSequence) mTSTestmodule.Sequence;
  
              Console.WriteLine ("Count TestSequence" + mTestSequence.Count);
  
              CANoe.TestCase mTestCase = (CANoe.TestCase) mTestSequence [1];
  
              Console.WriteLine ("Name of Testcase" + mTestCase.Name);
  
              mTestCase.Enabled = false; disable the unit test - XML and structured NET only module.
  CANoe.TestReport mTestReport = (CANoe.TestReport) mTSTestmodule.Report; Access to the report
  CANoe.Measurement mMeasurement = (CANoe.Measurement) mApp.Measurement;
  
              If (! mMeasurement.Running)
  
                  mMeasurement.Start ();
  mTSTestmodule.Start ();
  
  

  I realized that you can cast the ActiveX object references to another class of the child in the following way:

  

  It was the right solution and I want to share with you.

• Is there any unit test framework tools for DAQmx programmers who use C interface?

  I need to accuratly simulate DAQmx devices for the software in the development of unit tests. Are there tools available to make this easier?

  You have the integrated simulation of DAQ devices in MAX. The simulation is limited. It is explained in the NOR-DAQmx help (NI - DAQmx Key Concepts > NOR-DAQmx simulated devices).

• Unit Test Framework: Inline Subvi test coverage

  Hello

  does anyone know if the Unit Test Framework considers inline subVIs recursively during the measurement of coverage?

  Consider following the example:

  f(a:int) {}

  g() ;

  }

  g() {}

  If (false) - return 1;

  else return 0;

  }

  Obviously, there is no test for g() with coverage of 100% (branch), and any trial for f() reaches 100%.

  My question is: given a test for f(), UTF gives a different cover if I set to be (Inline g()<100%) or="" not="">

  Thank you

  Peter

  Peter,

  No, the Subvi cannot be analysed for coverage of the code if the value inline.

  Fact is, that this feature requires the option 'Allow debugging' must be disabled (Yes, I hate double-negation!), but if it is not allowed to debug, the code coverage will result in 0%.

  See Help:

  "You have to allow debugging for each VI under test to measure the code coverage. If VI a VI under test properties have not checked the checkbox allow debugging , the result of code coverage will always be zero. »

• Unit test, Visual Studio 2010 digital input read event

  Hello!

  I have problems in Visual Studio 2010, using NOR-DAQmx, but ONLY in a unit test project. I have compiled a dll that uses a DigitalChangeDetection task handler. The dll work very well in a draft standard form, but does not work in a Test project.

  I used .NET Framework 4.0 with success. Tried to switch to .NET framework 3.5, but it is not possible for a test project in Visual Studio 2010.

  When I start my test, it works fine until the event is raised. Once he does, the test will stop without exception or detail except the following result:

  "The agent process was stopped during the execution of the test."

  Nothing is caught in the trap in debugging.

  Also, I get the following in the Event Viewer error message:

  Log name: Application
  Source: VSTTExecution
  Date: 2010-12-01 11:32:31
  Event ID: 0
  Task category: no

  Description:
  The description for event ID 0 in source VSTTExecution is not found. Either the component that triggers this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

  If the event is on another computer, the display information had to be saved with the event.

  The following information has been included in the event:

  (devenv.exe, PID 5592, walk on 73) OutOfProcessStrategy.ProcessMonitorThread: The Agent process was closed unexpectedly. will attempt to restart

  the message resource is present, but the message is not in the string/message table

  I understand that Visual Studio 2010 is not yet officially supported so here's my 2 questions:

  -I'm the only one experiencing this problem? (Easily duplicated by taking the sample project: DotNET3.5\Digital\Read Values\ReadDigChan_ChangeDetection_Events and extract the relevent part of to put in a separate dll so that you can try to UnitTest in a project UnitTest.)

  -Update on what NOR-DAQmx will rely on VS2010? (I read here: http://forums.ni.com/t5/Measurement-Studio-for-NET/Support-for-Visual-Basic-2010-NET-4-Framework/m-p... this is supposed to be before the end of the year, but no updates would be great because I could not find any information on it)

  Best regards

  Hello Pierre,.

  As NOR-DAQmx is not yet officially supported in Visual Studio 2010, it is not quite clear why this problem occur. At this point, the official release date has not been announced yet, however, please continue to check the updates to www.ni.com/support (drivers and updates). Thank you

• Run unit tests different projects

  Hello

  I would like to start automatically tests in several projects.

  Here's the scenario: given A, B, C,... independently developed projects and say the developer has introduced an amendment that affects the B and C and maybe other projects too. now, I would like to re - run all unit tests in A, B, C,... to see if the change results in errors in B, C, or any other project.

  I thought to create a master project containing all the tests of A, B, C,... in auto-complete files but: 1) auto-complete files must be added manually and I would have a general solution; (2) auto fill records appear to be buggy or at least that they do is refresh as expected; in any case, 1) already is a show-stopper.

  LabVIEW can be script? Other solutions?

  Thank you

  Peter

  Peter,

  P@Anand referred to in the screw of the API of the UTF... You can use them to load unit tests and run independently of the project.

• Unit Testing Unit Test Framework when the expected production is just a table of NaNs to report a fake PASS

  It is a cross-post of the Unit Testing Group:

  https://decibel.NI.com/content/message/121915#121915

  I remember having this problem with the old version of the unit testing framework, but alas, it is still present in the new version.

  To do this, I use LabVIEW 2015.

  A customer contacted ask me what to do, because the expected output was table of NaNs and the VI under test returns an array of numbers and yet, the test was passing!

  My suggestion to use as a solution was to create a defined trial user who would test for the table of NaNs. I was wondering if someone here had found this problem and if you have further suggestions other than user defined Test.

  Until someone suggests we turn to JKI VI tester for this project, I can tell you that we use UTF and tester of JKI VI not because the client is in a regulated industry.

  A video describing the problem and the workaround (via user defined Tests) is here: https://youtu.be/AoBe-Gw2Nzo

  Question: Is using a user defined Test is the best approach? We missing something in the way that the Unit Test is defined which translates the fake of the Test infrastructure Unit reports that the test successful?

  Thank you

  Fab

  Hey Fab,

  I was able to reproduce the problem on my machine and I have observed the same results. What I see in the video, it looks that you are setting the unit test. I think that this is a bug rather than your test configuration, so I presented a report on this issue will have to be reviewed by the R & D.

  Go ahead, I agree that a user defined Test is the best solution in this case. If it meets the needs of your clients, I recommend you take this option.

• Distribution of the source - unit test dependency problem

  Hello

  I developed and API and I want to make the distribution of the sources, however my faulty build (error message is below) due to the error of reclassification of the Unit Test framework that I use to test my code. All Unit Tests are in the same folder, called "UnitTests", which is a part of a class. If I delete the UnitTests from the class folder, source distribution is created as expected. I try to put the folder always excluded UnitTests, but it does not help.

  I use LV 2012.

  Any ideas what I am doing wrong?

  Error message:

  LabVIEW does not find a file that is a dependency of a startup, exported or always included VI.

  File not found: the file "C:\Program Files (x 86) \National 2012\vi.lib\utf\dialogs\utf_defocus_trees.vi" must have the qualified name of "NI_UnitTestFramework.lvlib:utf_defocus_trees.vi", but it has the qualified name of "utf_defocus_trees.vi".

  The missing file can be referenced by one of the libraries included in the compilation or the file - CircularBuffer.lvlib. To resolve this problem:

  -Open all the startups, exported or always included live, recompile them (CTRL-SHIFT click the Run arrow) and keep them to update their dependencies.
  -Open libraries included in the building and check the existence and the location of the referenced files. Also, try building with the option of additional exclusion, 'Delete unused library of the project members', verified.

  Is attached to a fixed version of utf_defocus_trees.vi.  Place it in your \LabVIEW 2012\vi.lib\utf\dialogs directory .

  In addition, you might want to load/save utf_test_properties_sub.vi to get rid of the dirty dot.  This VI is located in the: \LabVIEW 2012\resource\framework\providers\utf.

• How calculated the code coverage in unit test infrastructure

  I'm looking for documentation on how the unit test framework calculates code coverage.

  I just recently installed the unit test framework and I had mixed results with the code coverage feature.  I manually calculated all the branch points in my vi, but the framework calculates more that I can think of, which gives a value of code coverage less than stellar (51%).  Is there documentation for how it is calculated?  I'm either missing something fundamental, or there is a bug with the framework.

  My vi consists of a loop (with shift registers) uninitialized which runs once.  On the inside of the loop is a business T/F structure that leads to a listed case structure possible two cases (one of which is the default value)... pretty basic.  Inside one of the structures is a loop and the other is cross.  For some reason, the unit test framework calculates 7 "flags chart run.  I use the method of "external" test harness to call all my test cases for the vi under test, b/c frankly it was easier to use than the UI provided.  I don't know if this is the cause, b/c I saw the other oddities when using it, which I'll save for another thread of discussion.

  Code coverage is calculated by dividing the number of diagrams, code that was executed by the number of diagrams in your VI altogether. Each VI has at least 1 schema (schema-block real). Loops have a single diagram each, case structures and sequences have a single diagram by image and so forth (=> from your description, your VI has at least 7 diagrams). You can double-click the patterns that were not executed in the Unit Test Framework results dialog box to be displayed.

  This approach does not reflect the amount or complexity of the code that contains each diagram. We looked at various ways of counting nodes, terminals, controls, son and other, that would give you a number that reflects your code with more precision. Unfortunately, neither of these approaches gives values that can easily be understood without some knowledge about the inner workings of LabVIEW. We chose to go with a solution that is completely transparent to end users.

  Thank you

• unit test framework

  Is it possible to group together the Unit Test framework in an EXE?  I would like to pass a path of the project file and path of the report file to an exe file that will reside on a dedicated test server and run tests or user-defined Unit Tests that are included in the project file.

  I want to use this EXE to run automated tests that can be triggered by a CI server like cruise control.

  Is there a limitation with a Toolbox or UTF specifically, which prevents the package in an EXE?

  You cannot run as a stand-alone executable Unit Test infrastructure. He uses a lot of functionality which is part of the LabVIEW development system, but not the LabVIEW runtime engine (for example in order to process the block diagrams, project files).

  What you can do in order to solve your use case is to install LabVIEW on your test machine and run a VI that runs your tests. There are several ways of commissioning and control of LabVIEW, including a command line interface that allows you to pass in a name of VI to run more parameters for the VI. A more accurate way to control LabVIEW would be through ActiveX, which is possible for example in a VB Script or JavaScript that are executed by the Windows Scripting Host.

  This piece of VBScript for example takes 2 inputs command line, start of LabVIEW, charge a VI, passes the values to the VI and run the VI. He will wait for LabVIEW is finished (as an option). You can also choose to keep LabVIEW run all the time, or to have the script open and close as needed.

  Dim oLV
  Set oLV = CreateObject("LabVIEW.Application")
  
  sCurPath = CreateObject("Scripting.FileSystemObject").GetAbsolutePathName(".")
  
  Dim oVI
  Set oVI = oLV.GetVIReference(sCurPath&"\LVDiff.llb\Diff_VI.vi")
  
  oVI.SetControlValue "Input 1", WScript.Arguments(0)
  oVI.SetControlValue "Input 2", WScript.Arguments(1)
  
  On Error Resume Next
  oVI.Run(0)
  If Err.Number>0 Then
      oVI.Abort
      MsgBox "Error"
  End If
  

  Hope that helps,

  Herbert
