Automating Software Testing with VectorCAST
The VectorCAST embedded software testing platform is a family of products that automates testing activities across the software development lifecycle. The purpose of this section is to provide a high-level view of what the VectorCAST products do, how they interwork, and how you might best use them to fully meet your own software testing needs.

What is RTCA DO-178C; EUROCAE ED-12C
One of the key requirements in the software verification process of DO-178C and ED-12C is achieving structural code coverage in conjunction with the testing of the highlevel and low-level software requirements.
These documents classify software into five levels of criticality based on whether atypical software behavior could cause or contribute to the failure of a system function. The table below shows the relationship between the failure condition category and the structural coverage objective as defined the standards.

Next-generation Automatically Generated Test Cases
Next-generation Automatically Generated Test Cases (ATG) is a “successor” to current basis path technology. It provides support for automatically generating high-coverage tests from the source code (both C and C++) and typically gives between 15%-20% higher coverage to basis path, but can be slower to generate. Next-gen ATG is integrated as a “background” process into the VectorCAST GUI to allow for tests to be generated while continuing to create and edit other tests types.
