We use fault injection to populate the database of failures for a target distributed system. When a failure is reported from production environment, the database is queried to find “matched” failures …

Fault Injection in Software Engineering - GeeksforGeeks

In contrast to traditional mutation testing where mutant faults are generated and injected into the code description of the model, application of a series of newly defined mutation operators directly to the model properties rather than to the model code has also been investigated. Mutant properties that are generated from the initial properties (or test cases) and validated by the model checker should be considered as new properties that have been missed during the initial verific… WebFault injection testing is a specific approach to testing one condition. It introduces a failure into a system to validate its robustness. Chaos engineering, coined by Netflix, is a practice for generating new information. There is an overlap in concerns and often in tooling between the terms, and many times chaos engineering uses fault ...
