It further reports on undertaken practical experiments thus strengthening the applicability of combinatorial testing to web application security testing. Detected flaws in cryptographic software code, reducing the test set size by 700X as compared with exhaustive testing, while retaining the same fault- detection capability. Combinatorial testing is being what is combinatorial testing applied successfully in nearly every industry, and is especially valuable for assurance of high-risk software with safety or security concerns. Combinatorial testing is referred to as effectively exhaustive, or pseudo-exhaustive, because it can be as effective as fully exhaustive testing, while reducing test set size by 20X to more than 100X.
Combinatorial testing is a method of experimental design that is used to generate test cases and is primarily used for commercial software testing. In addition to the discussion of the implementation of combinatorial testing techniques in video game testing, we present a method for finding combinations resulting in video game bugs. Consider the scenario where you have test data stored in an excel file. You may be testing the application manually or using test automation tools.

The project successfully implemented an unbiased and statistically based test methodology for Link 16 standards conformance that can ensure repeatability with a quantifiable increase in test space coverage. 80% module and branch coverage, 88% statement coverage 15 faults found; 2-way tests found as many as 3-way. Just like the CAGen tool, Pairwiser too requires one by one entering of all factors and their values. Similarly, constraints can be entered too in the format of if-then.
- The number of tests produced by ACTS or other covering array generators is proportional to vt log n, for v values per parameter, with n parameters, for a t-way covering array.
- Multiple studies have found 4-way to 6-way combination coverage was able to detect all faults found with exhaustive testing.

- The aim is to ensure that the product is bug-free and can handle different combinations or cases of the input configuration.
As a result, there is early and continuous delivery of quality products. ‘Enabled’, ‘Choice Type’ and ‘Category’ have a choice range of 2, 3 and 4, respectively. Multiplying the two largest values (3 and 4) indicates that a pair-wise tests would involve 12 tests. The pairwise test cases, generated by Microsoft’s “pict” tool, are shown below.
How does combinatorial testing perform in the real world: an empirical study
To detect interaction failures, software developers often use “pairwise testing”, in which all possible pairs of parameter values are covered by at least one test. Its effectiveness is based on the observation that software failures often involve interactions between parameters. For example, a router may be observed to fail only for a particular protocol when packet volume exceeds a certain rate, a 2-way interaction between protocol type and packet rate. Figure 1 illustrates how such a 2-way interaction may happen in code.
Tests for the validation of BenCIGen are derived from its requirements by using a combinatorial interaction approach. Moreover, we demonstrate the tool’s ability to generate benchmarks that reflect the characteristics of real software systems. BenCIGen not only facilitates the evaluation of existing generators but also serves as a valuable resource for researchers and practitioners seeking to enhance the quality and effectiveness of combinatorial testing methodologies. Combinatorial testing is a testing technique in which multiple combinations of the input parameters are used to perform testing of the software product. The aim is to ensure that the product is bug-free and can handle different combinations or cases of the input configuration.
One of the most commonly used combinatorial testing methods is the pairwise testing technique which involves testing all pairs of input variable values. These results are interesting because they suggest that, while pairwise testing is not sufficient, the degree of interaction involved in failures is relatively low. Testing all 4-way to 6-way combinations may therefore provide reasonably high assurance. As with most issues in software, however, the situation is not that simple.
The test scenarios result in that comes as a result of the above-mentioned tools can be inturn fed as an input to the test automation tools, thus speeding up the test design process. DevOps encourages Automation in all forms, and this is what a CTD tool precisely delivers by helping the QA engineer. It enables the team by using an automated fashion of producing an efficient test design.
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.
