The VI Analyzer Upgrade Tests and the upgrade documentation are tools to help you identify whether the improvements and bug fixes in your new version of LabVIEW change the behavor of your VIs.
For large sets of VIs, the VI Analyzer Upgrade Tests provide an efficient
way to identify many behavior changes caused by upgrading.
- Download the VI Analyzer Upgrade Tests for all versions of LabVIEW later than your previous version.
- Refer to the NI website at ni.com/info and enter the Info Code analyzevi to download these tests.
-
Open and run the tests by selecting and starting a new VI Analyzer task.
To analyze an entire project at once, select this menu option from the Project Explorer window rather than from a single VI.Resolve test failures by referring to Upgrade and Compatibility Issues for the version of LabVIEW that corresponds to the tests.
To confirm your VIs perform as well as they did in your previous version of
LabVIEW, run existing unit tests, integration tests, deployment tests, performance
tests, and stress tests in your new version of LabVIEW.
- Compare the results from your new version of LabVIEW to the results from your previous version. If you identify new behaviors, refer to the upgrade documentation to diagnose the source of the change.
- Upgrade and
Compatibility Issues—Lists changes that may break or affect the
behavior of your VIs. Refer to the subsections for each version of LabVIEW
beginning with your previous version. Tip To quickly locate deprecated objects and other objects mentioned in the Upgrade and Compatibility Issues topic, open your upgraded VIs and select .
- LabVIEW Release Notes—Lists known issues, bugs fixed since the last release, and other notes about this release.
- Module and toolkit documentation—Lists upgrade issues specific to some modules and toolkits, such as the LabVIEW FPGA Module and the LabVIEW Real-Time Module.
- Driver readme files—Lists upgrade
issues specific to each driver. To view the readme for your Driver, go to ni.com/manuals. Tip To determine whether a behavior change resulted from a driver update rather than an update to LabVIEW, test your VIs in the previous version of LabVIEW after installing the new version.
