IDKnown Issue
Toolkit - Desktop Execution Trace Toolkit
143563

Return
Event Details pane does not update when item found with the Find tool
When a search is conducted by clicking on the magnifying glass at the top right corner, resulting in an item being found and highlighted, the description pane at the bottom does not populate with details until you manually click on the highlighted item.

Workaround: Manually click on the item to see the details.

Reported Version: 1  Resolved Version: 2009  Added: 02/06/2009
143562

Return
Searching a filtered list of trace data returns filtered (hidden) events
When searching in a filtered list, results can be misleading since the search also finds items that have filtered out. The scrollbar might jump to a place in the trace which is hidden due to the applied filter

Workaround: N/A

Reported Version: 1  Resolved Version: 2009  Added: 02/12/2009
144661

Return
UI does not indicate when trace session context is invalid
The Desktop Execution Trace Toolkit User Interface appears as if it is connected to a valid application instance that can be configured or traced even when it is not valid or possible. For example; on loading a saved trace when LabVIEW is not open, the Start, Configure etc. buttons are still enabled.

Workaround: N/A

Reported Version: 1  Resolved Version: 2009  Added: 02/12/2009
149516

Return
Inconsistent behavior when tracing two application instances simultaneously

Workaround: Trace only one event at a time

Toolkit - Report Generation
123064

Return
Cannot access specific document references using the Report Generation Tool VIs in LabVIEW 8.6
Previously it was possible to access the references to MS Office documents by unbundling the refnum of the report that was passed through the report generation VIs. The Report Generation VIs were rewritten using LabVIEW classes, hence making this not possible.

Workaround: The refererence is still contained within the report object in LabVIEW 8.6, however, each type of report has its own class that inherits from a base class. The NI_Report.lvclass is not locked, although some of the specific classes (Word, Excel) are. You can alter a VI that was correctly mutated and that has access to the private class to pass the desired reference out of the function by wiring it to the connector pane of the parent class as well as all daughter classes. Please refer to NI KB 4OOCSJ4M for more information about this problem and workaround.

Reported Version: 1.1.3  Resolved Version: 1.1.4  Added: 08/26/2008
Toolkit - Unit Test Framework
129739

Return
Code coverage for results include only those VIs that have tests defined for
Code coverage is calculated only during test execution. VIs that are not tested by the Unit Test Framework will not be included in the code coverage analysis. They will not influence the overall code coverage percentage for the project. They will also not be listed in the results window or in report files.

Workaround: N/A

Reported Version: 1  Resolved Version: 2010  Added: 02/06/2009
133136

Return
Test Properties dialog box does not show up on the Windows taskbar
The "Test Properties" dialog page is not modal. The dialog does not show up in the Windows taskbar. It can be hidden behind other open windows in LabVIEW, for example Front Panels and Block Diagrams.

Workaround: N/A

Reported Version: 1  Resolved Version: 2009  Added: 02/06/2009
135602

Return
Controls with the same name on the front panel are not supported for a VI under test.
You cannot have controls with the same name in the front panel of a VI under test. Although you can create tests for this VI, you will get testing errors when executing these tests.

Workaround: N/A

Reported Version: 1  Resolved Version: 2009  Added: 02/06/2009
136015

Return
Code coverage analysis requires "Allow Debuging" to be set on VI under test
If the VI properties of a VI under test does not have a checkmark in the Allow debugging checkbox, code coverage result will always be zero.

Workaround: Check the "Allow debugging" option for VIs under test.

Reported Version: 1  Resolved Version: 2010  Added: 02/06/2009
136421

Return
Test configuration and test execution will cause a dirty dot on the project
Test configuration and test execution temporarily modifies the project in memory. None of this will affect the project information that is written to disk. However, it will prompt users to save the project when closing it in LabVIEW.

Workaround: N/A

Reported Version: 1  Resolved Version: 2010  Added: 02/06/2009
136833

Return
Errors that occur in user-defined tests do not appear in the Unit Test Framework Results window.

Workaround: You must wire the following error result information to the Unit Test Framework Results indicator in order for errors to appear in the Unit Test Framework Results window. 1) Set the result (test) indicator to return Error. 2) Set the result indicator to return Error. 3) Set the error message indicator to return a text string of the error.

Reported Version: 1  Resolved Version: 2009  Added: 02/06/2009
137169

Return
Aborting test execution does not work for user-defined test VIs with infinite loops

Workaround: Do not use an endless loop in a user-defined test VI.

Reported Version: 1  Resolved Version: 2009  Added: 02/06/2009
137607

Return
HTML report does not contain the error detail information
Error codes and error sources for test errors are not listed in HTML reports.

Workaround: Generate text reports to see the test error detail information.

Reported Version: 1  Resolved Version: 2009  Added: 02/06/2009
138194

Return
Unit Test Framework will hang if two controls in a cluster on the front panel of a target VI have the same name
Unit Test Framework will hang during test execution if two controls in a cluster on the front panel of the VI under test have the same label text, and the test has this cluster as an output. Test execution will also work if the controls are on different levels within nested clusters.

Workaround: Rename the controls to have different names on the front panel and update the test.

Reported Version: 1  Resolved Version: 2009  Added: 02/06/2009
138423

Return
The Run Tests from File VI produces load conflicts when the library names collide
A test that uses A.lvlib can produce a load conflict if a different A.lvlib is still in memory from a previous test execution. This can happen if the programmatic API, Run Tests from File.vi, is used to execute multiple tests or all tests from multiple projects in a row (without exiting the VI in between test executions), and the subVIs used by VIs under test are password-protected and in libraries with the same name in different projects.

Workaround: The two options are 1) Input passwords for the conflicted subVIs. 2) Use "Run Tests from Project.vi" instead of "Run Tests from File.vi".

Reported Version: 1  Resolved Version: 2009  Added: 02/06/2009
138575

Return
Unit Test Framework Results window does not show up in Windows taskbar
The Unit Test Framework Results Window is not modal. Multiple results windows can be opened in order to compare results from different test executions. The results window can be hidden behind other open windows in LabVIEW, for example Block Diagrams or Front Panels

Workaround: N/A

Reported Version: 1  Resolved Version: 2009  Added: 02/06/2009
151407

Return
Code coverage analysis requires "Allow Debuging" to be set on VI under test
If the VI properties of a VI under test does not have a checkmark in the Allow debugging checkbox, code coverage result will always be zero.

Workaround: Check the "Allow debugging" option for VIs under test.

Reported Version: 1  Resolved Version: 2009  Added: 02/06/2009
136977

Return
Cannot stop the execution of a test that contains an infinite while loop on a Real-Time target
You cannot stop the execution of a test on a Real-Time target if the VI under test contains a While loop that loops forever.

Workaround: Configure a timeout for the test.

Reported Version: 1  Resolved Version: 2009  Added: 03/25/2009
137827

Return
Array Range (Limit Array) comparison type does not work for enum arrays
The array range (limit array) comparison type does not work for enum arrays. It will result in an error "VI under test is broken"

Workaround: N/A

Reported Version: 1  Resolved Version: 2009  Added: 03/25/2009
155781

Return
Creating or executing tests on polymorphic VIs is not supported

Workaround: N/A

Reported Version: 1  Resolved Version: 2009  Added: 03/25/2009
138800

Return
Tests fail for subroutine priority VIs
The test framework doesn't work with subroutine priority VIs. The tests will always fail.

Workaround: N/A

Reported Version: 1  Resolved Version: 2009  Added: 05/13/2009
141551

Return
Saving and loading date/time values causes a 1 hour difference in some situations
Timestamp control whose value is in daylight saving time becomes +1 hour offset to the value in the front panel when saved in .lvtest file.

Workaround: N/A

Reported Version: 1  Resolved Version: 2009  Added: 05/13/2009
138166

Return
"Find VI" does not work after creating a new test in auto populating folder
