• 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.

• 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,

• 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. »

• 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

  John

  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?

• VI test a string control configured to view password, it displays 'normal view' mode in the Unit Test Framework lvtest Properties dialog box

  Configuration of the password does not lvtest UTF Properties dialog window. It's probably a bug.

  Hey jorgeinSD,

  The Unit Test is designed to test the input values and compare them with a desired output value to make sure that your VI works under different entries. For this reason, it is necessary that the user makes tests see the entry and not just values «*» Your VI should not change (as in the VI should still display mode password, ' * '), but the properties of Unit Test should display the actual value and not mode password. Is that what you mean by 'configuration of the password does not UTF' or did, I misunderstood the question? I hope this helps!

• 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

• renaming of unit test

  After the discussion here:

  http://forums.NI.com/T5/LabVIEW/cannot-rename-lvtest-file/m-p/2621909/highlight/true#M785332

  I eventually create several dummy unit tests in the lvproj then exit and restart labview and then correctly configure these dummy unit with own names test.

  What is the Unit Test framework in $$? Pretty boring we can if expect a simple rename the feature to $$.

  Has anyone found alternative workaround in the meantime?

• PL/SQL, used in application of the APEX of unit tests

  question by my client:

  I develop an Oracle Application Express application and work on unit tests for stored procedures in PL/SQL and the packages that are stored in the underlying database and used by the application of the APEX. These unit tests must run in the context of SQL Developer Unit Test.
  The problem is that the PL/SQL code stored in the database using functions such as NV('APPLICATION_ITEM') to access items in the application of the apex. They do return all values when I try to execute the PL/SQL within the unit test framework, that is to say in the backend. While it is good that the NV is not error, NULL haven't really work well in my scenario either (for example when the result of this function is inserted into a column NOT NULL in a table). I can think of a few workarounds, such as the creation of my own function NV within the schema to test return values desirable, but nothing seems a really satisfactory solution. I wonder if there is no recommendation to Oracle for this scenario - how can I run code that uses the APEX via backend-specific features. I found nothing in the documentation of the APEX for this but I would like to know if there is a recommendation how to better deal with this case.
  
  I use SQL Developer version 4.0.0.13.80

  Hello

  Indeed, you must set your PL/SQL function calls. This would be the cleanest solution.

  There is an alternative. Please see the following article on the creation of an APEX in PL/SQL session: Martin Giffy D'Souza on Oracle APEX: how to create a Session of the APEX in PL/SQL

  This approach allows to set the values of APEX application item before you run your unit tests. I don't know if it's possible in SQL Developer Unit Test, but it might get you further down the road.

  Good luck

• Developer SQL 3 EA1: Unit Test

  Hello
  
  I just started to use the work unit test framework in SQL Developer 3 EA 1 and I need assistance, definition of a test case involving parent - child tables that are handled using an API from plsql. The API for the child table requires a registration key in the parent table. The parent record and its key is created by a process of starting test case. The key is retrieved using a query of dynamic value in the implementation of the test. It seems that the dynamic value query is executed before the start of the test case process have been executed. Is this expected behavior? My expectation is that the boot process are executed before the dynamic values query.
  
  Also, is it possible to use values resulting from processes of startup as the case other than type parameter values by using a dynamic query in value?
  
  Summary test scenario:
  
  2 boot process: the first deletes all the data tables parent and the child. The second inserts in a record in the parent table.
  
  No disassembly process.
  
  Test implementation: application of dynamic value that selects the key of the parent table and defines literals for the remaining parameters of test cases.
  
  1 process validation: check if a record has been inserted into the table of childe with expected values.
  
  Thank you
  
  Alistair

  Hi Alistair.

  We execute the dynamic query to control how many times the test (start, test cases, validation, demolish) cycle runs.

  To get the behavior you want, put the test in a test suite and test suite start do the initialization of the table for you.

• 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?

  Thank you

  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.

• Problem with Unit Test

  What I am doing wrong?

  I created a small example of how to test the functionality of substitution of variables within the unit test framework.

  Documentation: SQL Developer: unit tests

  create or replace procedure SimpleTestProcedure (param1 in varchar2) as

  Start

  null;

  end SimpleTestProcedure;

  /

  Test configuration with the following configuration:

  Input value: Test

  Process: Boolean function

  declare

  Param varchar2 (4 char);

  Start

  param: =: param1;

  If "{param1}"! = param then

  Returns false;

  end if;

  end;

  

  Is found in the following message is displayed after the test run:

  

  I use SQL Developer Version 4.0.3.16.

  Any help would be appreciated!

  Kind regards.
  

  Hi Flofe,

  It looks like the Boolean function as a validation of process takes no parameters that a function pl/sql 'generic' put... it's probably called "function" only because it returns a value, as does any function. But you can use substitutions of setting the parameters for the stored procedure that you are testing, which you are already doing.

  So, try to change your code to:

  declare

  Param varchar2 (8);

  Start

  param: = "{param1}";

  If "{param1}"! = param then

  Returns false;

  on the other

  Returns true;

  end if;

  end;

  And it should work for try you the little test...

  I hope this helps...
