LabVIEW toolkits automate software testing

National Instruments has released the NI LabVIEW Unit Test Framework and LabVIEW Desktop Execution Trace toolkits, which are new software engineering tools for the LabVIEW graphical development environment. When developing large-scale or complex applications with LabVIEW software, engineers can use these toolkits to help validate systems, improve software quality and test code against requirements.

Software debugging and testing is a complex, expensive and time-consuming task for developers. As the complexity and sophistication of software increase, developers need more regimented and automated procedures to ensure thorough testing and help with code validation. The new toolkits are designed to automate and improve common software engineering tasks.

With the Unit Test Framework toolkit, engineers can automate requirements-based testing and the validation of VIs developed in LabVIEW. Automating this process reduces the amount of time developers spend performing tests and enables more exhaustive testing. Engineers can specify test cases that define inputs and compare the results after execution with expected output to perform functional and regression testing of software. The included reporting functionality can automatically generate validation documents in HTML, ATML/XML or ASCII formats, which are valuable for documenting that the application works correctly. The toolkit also integrates with NI Requirements Gateway to help engineers manage requirements documents for software testing, track the amount of coverage and understand the impact of changes.

The Desktop Execution Trace Toolkit is a dynamic code analyser that engineers can use during runtime to detect and locate problems in code that could impact performance or cause unexpected behaviour. It shows a chronological view of events, queue operations, reference leaks, memory allocation, unhandled errors and subVI execution. Highlighting individual events gives engineers additional information such as the call chain, thread ID and CPU number to help them debug and optimise their LabVIEW code. They can also double-click many events to highlight the corresponding object on the block diagram.
