Test Case
Expected Output Actual Result=
A test case is a document that contains detailed instructions for testing the functionality of a software application
A Robust Test case should beIndependent to meet specific requirementsEasily understandable during testingFree from spelling and grammatical mistakes.Able to cover at least one functionality or requirementAble to uncover bugs
Test Components Test Case Name Objectives Test Case ID

Black Box Test Design Technique
Boundary Value Analysis
Equivalence partitioning
Error Guessing
State Transition
Syntax Testing
Cause effect Graphic
Represents a set of valid and invalid conditions Test condition which give similar results are grouped under one partition Number of test cases is reduced considerably
Identifies bugs around the boundaries. Takes into account output specifications when deriving test cases Used to test the behavior of the application where the bug is most likely to occur
ADHOC method to identify tests that are likely to expose bugs. Enables to make guess about bugs that are likely to be present in the application Test Activities based on areas that are not covered by formal design techniques.
Enables you to test the transition from one state to another Identifies the events which causes the transition and specifies Actions that result from
the transition
Used to design test cases for software applications based on the syntax of the input. Test the application with different set of input values
Used to identify possible causes of a problem by using the cause effect diagram Analyze Cause of the problem Identify the source of bugs and Observe the effects of the problem.
