Means that every point of entry and exit in the program has been invoked at least once and that each decision in the program has been taken on all possible (Boolean) outcomes at least once. Essentially, this means that every Boolean statement has been evaluated both TRUE and FALSE.

To what do DO-178B levels refer?

Esterel Technologies
DO-178B software levels (A, B, etc.) are based on the potential of the software to cause safety-related failures identified in the system safety assessment. DO-178B has five levels of certification:

Who determines which DO-178B level is required?

Esterel Technologies
The level to which a particular system must be certified is selected by a process of failure analysis and input from the device manufacturers and the certifying authority (FAA or JAA), with the final decision made by the certifying authority. Note that software does not need to be certified specifically at each designated level. Certification at any level automatically covers the lower-level requirement; but, obviously, the converse is not true.

What is DO-178B?

Esterel Technologies
DO178, currently known as DO-178B, is described in RTCA Document RTCA/DO-178B, titled Software Considerations in Airborne Systems and Equipment Certification. This specification was developed by the avionics industry to establish software considerations for developers, installers, and users, when aircraft equipment design is implemented using microcomputer techniques.

What is the difference between structural and functional testing?

Basic Faqs in Software Testing
Functional testing is a "black box" (behavioral) testing where the tester verifies the functional specification. Bottom-up approach: In this approach testing is conducted from sub module to main module, if the main module is not developed a temporary program called DRIVERS is used to simulate the main module. Top-down approach: In this approach testing is conducted from main module to sub module.

Hips - Canine Hip Diplasia (CHD) merits concern by all doodle breeders and its prevalence may be reduced with selective breeding. CHD is caused by a poorly formed ball-and-socket joint in the hip.
