Abstract: Automated requirements-based test case generation method includes constructing in a model-based development tool a software architecture model automatically derived from architectural information of a software design model, allocating requirement models into blocks/operators of the software architecture model, and generating component level requirements-based test cases from the software architecture. The component level requirements-based test case generation method includes receiving a software architecture along with allocated requirement models represented in hierarchical data flow diagram, selecting one of the software components, building an intermediate test model based on the selected component by automatically attaching at least one of test objectives or constraints to the corresponding software architecture model blocks/operators based on the selected test strategy, and generating human and machine readable test cases with the test generator for further automatic conversion to test executable and test review artifacts. A system and a non-transitory computer-readable medium for implementing the method are also disclosed.

Abstract: A system for equivalence class analysis-based automated requirements-based test case generation includes a control processor, a data store containing textual design requirements, a textual converter unit structured to convert the textual design requirements to a machine-readable version of design requirements, a requirement partition unit configured to partition the machine-readable design requirements into one or more sets of related design requirements, an equivalence class partition unit configured to process the machine-readable design requirements and input/output variables into a set of equivalence classes, an equivalence class analyzer unit structured to analyze the set of equivalence classes to generate equivalence class tests and identify uncovered input space, and a boundary class analyzer unit structured to identify boundaries of the equivalence classes and generate boundary value tests and robustness tests. A method for equivalence class analysis-based automated requirements-based test case generation implementable on the system, and a non-transitory computer readable medium are also disclosed.

Abstract: A method and system, the method including receiving a set of requirements for a software application, the set of requirements comprising a plurality of software requirements identified for the software application; analyzing the set of requirements to determine dependencies between the plurality of software requirements in the set of requirements; generating a visualization of the determined dependencies and test boundaries between the plurality of software requirements in the set of requirements; storing the generated visualization of the determined dependencies and test boundaries between the plurality of software requirements in the set of requirements in a record; and applying the determined dependencies in the record to at least one of (i) optimize test steps in a test procedure and (ii) generate an executable test procedure that exercises external inputs and outputs for the software application.

Abstract: According to some embodiments, an Arbitrary Software Logic Modeling (“ASLM”) data source may store electronic records associated with units, each electronic record including a unit identifier, one or more identification tags, context data, unit parameters, unit variables, and internal logic. An ASLM platform may express system requirements at a logic block level and establish the logic blocks as self-contained entities and connections in accordance with the system requirements (the established logic blocks graphically representing systems logic). The ASLM platform may then explicitly transform the systems logic automatically to output language agnostic common design information exchange model information. The ASLM platform may also translate and maintain traceability among the system requirements, common design information exchange model information, and generated code.

Abstract: Automated requirements-based test case generation method includes constructing a software architecture model derived from software design model architectural information, allocating requirement models into blocks/operators of the software architecture model, and generating component-level requirements-based test cases from the software architecture configured to be executable at different levels in the software architecture. The component-level requirements-based test case generation method includes receiving a software architecture along with allocated requirement models represented in hierarchical data flow diagram, selecting one of the software components, building an intermediate test model based on the selected component by automatically attaching at least one of test objectives or constraints to the corresponding software architecture model blocks/operators based on the selected test strategy, and generating human and machine readable test cases with the test generator for further automatic conversion to test executable and test review artifacts. A system and a non-transitory computer-readable medium for implementing the method are also disclosed.
