Scenario testing is a software testing activity that uses scenarios: hypothetical stories to help the tester work through a complex problem or test system.The ideal scenario test is a credible, complex, compelling or motivating story; the outcome of which is easy to evaluate. [1]
The standard formed part of the training syllabus of the ISEB Foundation and Practitioner Certificates in Software Testing promoted by the British Computer Society. ISTQB, following the formation of its own syllabus based on ISEB's and Germany's ASQF syllabi, also adopted IEEE 829 as the reference standard for software and system test documentation.
A key aspect of specification by example is creating a single source of truth about required changes from all perspectives. When business analysts work on their own documents, software developers maintain their own documentation and testers maintain a separate set of functional tests, software delivery effectiveness is significantly reduced by the need to constantly coordinate and synchronise ...
Entire test suites or test cases exposing real bugs can be automatically generated by software using model checking or symbolic execution.Model checking can ensure all the paths of a simple program are exercised, while symbolic execution can detect bugs and generate a test case that will expose the bug when the software is run using this test case.
Effective layout of a test case ensures all required actions are completed, improves the readability of the test case, and smooths the flow of execution. Consistent structure helps in building a self-documenting test case. A commonly applied structure for test cases has (1) setup, (2) execution, (3) validation, and (4) cleanup.
To find test cases that can cover an appropriate, but finite, number of paths, test criteria are needed to guide the selection. This technique was first proposed by Offutt and Abdurazik in the paper that started model-based testing. [3] Multiple techniques for test case generation have been developed and are surveyed by Rushby. [4]
If the new feature is part of any existing feature, then share the test cases of new and existing features among them. Finally combine all test cases from current version and previous one and record all the results. [11] There is a predefined rule to calculate count of new test cases for the software.
The minimum number of test cases is the number of classes in the classification with the most containing classes. In the second step, test cases are composed by selecting exactly one class from every classification of the classification tree. The selection of test cases originally [3] was a manual task to be performed by the test engineer.
