"In the field application, we discovered two fault cases in real products under development using our framework. According to our analysis, these cases could not have been found using manual testing, but made possible by our testing framework. These cases could have cost the company tens of million dollars each, if they were not discovered until after sale." |

From January 2016 to February 2016, authors tested three real-life software systems using CT, and compared the results to errors that had been discovered using conventional methods, finding roughly 3X as many bugs in one-fourth of the time, for a 12X increase in test efficiency.

"In the proposed method the SE coverage normalized by the number of CTUs is 84 times higher compared to that in the HEVC conformance test suite. This means that we can verify the HEVC decoders 84 times faster with the test bitstream set obtained by the proposed method, compared to the HEVC conformance test suite."

In this paper, we present results on the application of a systematic testing methodology called Pseudo-Exhaustive testing. The systematic testing methods were applied at the unit, module integration levels of the software. The findings suggest that Pseudo Exhaustive testing supported by automated testing technology is an effective approach to testing real-time embedded digital devices in critical nuclear applications. |

Autonomous systems pose new challenges in conducting test and evaluation that assures adequate performance, safety, and cybersecurity outcomes. We propose an autonomous systems architecture concept and map the elements of a decision theoretic view of a generic decision problem to the components of this architecture. These models offer a foundation for developing a decision-based, common framework for autonomous systems. We also identify some of the various challenges faced by the Department of Defense (DoD) test and evaluation community in assuring the behavior of autonomous systems as well as test and evaluation requirements, processes, and methods needed to address these challenges. |

Abstract. A combination of parameters is called a test case; hence, the challenge is to search collision test cases from the extremely large number of combinations. A rule-based method is the main focus because an explicit method of searching test cases is required in certain industries in the real world. In this study, a method of rule-based searching for collision test cases of autonomous vehicles simulations is proposed. Simulation models that have rules between an AD car and other cars are defined. Experiments on AD simulations involving the simulation models of a three-lane highway and a signalised intersection were conducted. The results indicate the efficiency of the method. |

Abstract. We are investigating a new test development method that aims to maximize the confidence to be achieved by combining Assurance Cases with High Throughput Testing (HTT). Assurance Cases, developed for safety-critical systems, are a rigorous argument that the system satisfies a property (e.g., the Mars rover will not tip over during a traverse). They integrate testing, analysis, and environmental and operational assumptions, from which the set of conditions that testing must cover is determined. In our method, information from the Assurance Case is used to determine the test coverage needed, and then input to HTT to generate the minimal test suites needed to provide that coverage.

"It's always an important issue for testers and software managers to decide how much testing should be enough [11] Game quality has to be good enough for customer, but testing has to stop before the release date. It is neither practical nor economical, to test every possible combination of game event, conguration, function and options. Skipping some testing or taking shortcuts is always risky. Combinatorial testing is a quick way to find defects earlier in the game while keeping the test sets small, covering as much area as possible."

"Embedded electrical systems for passenger vehicles are highly complex distributed systems with varying system boundaries. The surge towards further electrification of vehicles demands the deployment of high voltage systems that provide propulsion through an electric motor as part of a hybrid electric or pure electric drivetrain. This demands additional care and robust deployment to ensure the safety of the end user and the environment around them. Exhaustive testing is not feasible for large systems and the use of formal approaches can be restrictive. In the presented work a combinatorial test approach is applied to a real Hybrid Electric Vehicle control system as part of a hardware-in-the-loop test system." |

|
The evaluated results indicate that both techniques succeed in detecting security leaks in web applications with different results, depending on the background logic of the testing approach. Last but not least, we claim that attack pattern-based combinatorial testing with constraints can be an alternative method for web application security testing, especially when we compare our method to other test generation techniques like fuzz testing.

“Industry proof-of-concept demonstration that used this approach to automate parts of the unit and integration testing of a 196 KSLOC avionics system. The goal was to see if it might cost-effectively reduce rework by reducing the number of software defects escaping into system test – if it was adequately accurate, rigorous, thorough, scalable, mature, easy to learn, easy to use, etc. Overcoming scalability issues required moderate effort, but in general it was effective – e.g., generating 47,040 test cases (input vectors, expected outputs) in 75 seconds, executing and analyzing them in 2.6 hours. It subsequently detected all seeded defects, and achieved nearly 100% structural coverage.”

|
Abstract—Modern passenger cars have a comprehensive embedded distributed system with a huge number of bus devices interlinked in several communication networks. The number of (distributed) features and hence the risk of undesired feature interaction within this distributed system rises significantly. Such distributed automotive features pose a huge challenge in terms of efficient testing. Bringing together Combinatorial Testing with Automated Feature-Interaction Testing reduces the testing effort for such features significantly.

Abstract. Combinatorial strategies are extended to generate invalid test inputs but the effectiveness of negative test scenarios is yet unclear. Therefore, we conduct a case study and analyze 434 failures reported as bugs of a financial enterprise application. As a result, 51 robustness failures are identified including failures triggered by invalid value combinations and failures triggered by interactions of valid and invalid values.

We also found positive correlations relating the number of bugs in Drupal features to their size, cyclomatic complexity, number of changes and fault history. To show the feasibility of our work, we evaluated the effectiveness of non-functional data for test case prioritization in Drupal. Results show that non-functional attributes are effective at accelerating the detection of faults, outperforming related prioritization criteria as test case similarity."

We develop test-case selection techniques, where test strings are synthesized using characters or string fragments that may lead to system failure. Demonstrated discovery of a number of "corner-cases" that had not been identified previously. We also present simple heuristics for isolating the fault causing factors that can lead to such system failures. The test method and input model described in this paper have immediate application to other systems that provide complex full text search.
