In software engineering, a test case is a specification of the inputs, execution conditions, testing procedure, and expected results that define a single test to be executed to achieve a particular software testing objective, such as to exercise a particular program path or to verify compliance with a specific requirement.

In model-based testing, one distinguishes between abstract test suites, which are collections of abstract test cases derived from a high-level model of the system under test, and executable test suites, which are derived from abstract test suites by providing the concrete, lower-level details needed to execute this suite by a program.

Metamorphic testing (MT) is a property-based software testing technique, which can be an effective approach for addressing the test oracle problem and test case generation problem. The test oracle problem is the difficulty of determining the expected outcomes of selected test cases or to determine whether the actual outputs agree with the ...
In software engineering, graphical user interface testing is the process of testing a product's graphical user interface (GUI) to ensure it meets its specifications. This is normally done through the use of a variety of test cases .
Having test cases depend on system state manipulated from previously executed test cases (i.e., you should always start a unit test from a known and pre-configured state). Dependencies between test cases. A test suite where test cases are dependent upon each other is brittle and complex. Execution order should not be presumed.
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.
While testing software projects, certain test cases will be treated as the most important ones, and if they fail the product cannot be released. Some other test cases may be of lesser functional importance, or even cosmetic and if they fail, we can release the product without much compromise on the functionality. These priority levels must be ...
Ad hoc testing is not limited to software development. Ad hoc testing has been applied in other scientific and quality management scenarios. For example, ad hoc testing has been applied in standardized on-site testing at healthcare facilities of "the electromagnetic immunity of medical devices and help identify interference issues that might exist with critical medical devices as a result of ...
