QA Systems Announces Version 9.1 of the Cantata Unit Test Tool


Today QA Systems announced the General Availability of Cantata version 9.1, the unit and integration testing tool for C and C++. The most important elements of the new version are: an enhanced AutoTest capability for automatic test generation for C++ code, dramatically faster data loading in the GUI, and new HTML format test results which can be used as certification evidence for all software safety standards supported by Cantata.

In Cantata 9.1, AutoTest now supports all C++ language features in C++11 / 14, Real-Time Type Information, and additionally, improved C++ template instantiation.

In this version, the Cantata GUI has been optimised to accelerate data loading across the various test views. As Pierre-Henri Stanek, the Cantata Product Manager explained “With ever larger and more complex test projects, the amount of data loading required by the GUI has increased. Using a benchmark C++ project of 135 source files Cantata 9.1 generated a test in only 5 seconds, compared to 30 seconds in 9.0 (so 6 times faster). This benchmark illustrates advantage of staying up to date with Cantata versions.”

Cantata 9.1 now includes a new Cantata Core Product executable which automatically converts ASCII text results files to certified user-friendly HTML format, for sharing test results over company network and between collaborative working tools.

Other elements of interest to existing Cantata users in this release include easier management of Cantata controlled function calls expected during test case execution withing the Test Case Editor, and more flexible inclusion / exclusion and reporting for code coverage. For more details, these users can refer to What’s New in Cantata 9.1.

Cantata version 9.1 is available from 30 October 2020. For further information, please visit, or contact
