A test case usually contains a single step or a sequence of steps to test the correct behavior/functionality and features of an application. An expected result or expected outcome is usually given. Additional information that may be included: [7] Test case ID - A unique identifier for the test case. Description/summary - The test case objective.
Process steps for a happy path are also used in the context of a use case. In contrast to the happy path, process steps for alternate flow and exception flow may also be documented. [3] Happy path test is a well-defined test case using known input, which executes without exception and produces an expected output. [4]
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 ]
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 ...
A test case graph illustrates all the necessary independent paths (test cases) to cover all isolated conditions. Conditions are represented by nodes, and condition values (situations) by edges. An edge addresses all program situations. Each situation is connected to one preceding and successive condition.
Based on this, the tool breaks each scenario up into meaningful clauses. Each individual clause in a scenario is transformed into some sort of parameter for a test for the user story. This part requires project-specific work by the software developers. The framework then executes the test for each scenario, with the parameters from that scenario.
A system sequence diagram should be done for the main success scenario of the use case, and frequent or complex alternative scenarios. There are two kinds of sequence diagrams: Sequence Diagram (SD) : A regular version of sequence diagram describes how the system operates, and every object within a system is described specifically.
Test-driven development (TDD) is a way of writing code that involves writing an automated unit-level test case that fails, then writing just enough code to make the test pass, then refactoring both the test code and the production code, then repeating with another new test case.
