Whitepaper: Optimizing Unit and Regression Testing for Embedded Systems

Automate to Save Time and Gain Better Coverage

Move away from test suites that require a lot of manual intervention. Automation results in faster and easier testing. That means more time to reach better test coverage and other safety and quality objectives.

Unit and regression testing are important to the foundation of modern testing processes for embedded and safety-critical systems. Following best practices and leveraging the full capabilities of a modern test automation tool improves testing efficiency and testing outcomes that result in high quality, safe, and secure software systems.

Learn how to optimize unit and regression testing for embedded systems with:

  • Automated test execution
  • Automated test case generation
  • Testing best practices
  • Code coverage
  • Test impact analysis

Test automation provides a large benefit to embedded software. Moving away
from test suites that require a lot of manual intervention results in testing that
can be done quicker, easier, and more often.

Unit test automation tools universally support some sort of test framework,
which provides the harness infrastructure to execute code units in isolation
while satisfying dependencies via stubs. Parasoft C/C++test is no exception.
Part of its unit test capability includes the automated generation of test
harnesses and the executable components needed for host and on-target based
testing.

Best practices for building, running, and maintaining unit tests play a big role
in getting the most return on investment from unit and regression testing and
test automation tools.

Code coverage is a measurement of how much of the production code is executed while your automated tests are running. By running a suite of tests and looking at code coverage data, there is a general sense of how much of the application is being tested.

It’s not uncommon to default to running all regression tests when there’s doubt on what impact recent code changes have had—the all-or-nothing approach. For large software projects, this becomes a huge undertaking and drags down the productivity of the team. This inability to focus testing hinders much of the benefits of iterative and continuous processes, potentially exacerbated in embedded software where test targets are a limited resource.
