The document discusses test case structure and provides an example of a test case with the following key elements: 1) It defines a test case as a set of test inputs, execution conditions, and expected results to exercise a specific program path or requirement. 2) It outlines the typical sections of a test case including general information, activities, inputs, and expected vs. actual results. 3) It provides an example test case to verify an error message appears when invalid values are entered.

2. Test case vs Scenario A set of test inputs, execution conditions, and expected results developed for a particular objective, such as to exercise a particular program path or to verify compliance with a specific requirement a test case must be reasonably capable of revealing information Scenario – it is a general description of a particular requirement/functionality Test case – it is the interpretation of the scenario with actual data

3. Scenario - Example no specific values for input data TRACEABILITY! Identifier Scenario01 Conditions satisfied BA 9 Scenario description Run the application so that the UI panel appears. Enter invalid values like non integers, chars or strings for a , b and c respectively. Click "Verifica". Output The following error message is displayed, written in red italic: "Valorile date nu se incadreaza in intervalul specificat."

4. Test case structure - Information Information contains general information about Test case. Identifier is unique identifier of test case for further references, for example, while describing found defect. Test case owner/creator is name of tester or test designer, who created test or is responsible for its development Version of current Test case definition Name of test case should be human-oriented title which allows to quickly understand test case purpose and scope. Identifier of requirement which is covered by test case. Purpose contains short description of test purpose, what functionality it checks. Dependencies

5. Test case structure - Activity Testing environment/configuration contains information about configuration of hardware or software which must be met while executing test case Initialization describes actions, which must be performed before test case execution is started. For example, we should open some file. Finalization describes actions to be done after test case is performed. For example if test case crashes database, tester should restore it before other test cases will be performed. Actions step by step to be done to complete test. Input data description

6. Test case structure - Results Expected results contains description of what tester should see after all test steps has been completed Actual results contains a brief description of what the tester saw after the test steps has been completed. This is often replaced with a Pass/Fail . Quite often if a test case fails, reference to the defect involved should be listed in this column. Actual results field will be filled in after running the test case

7. Test case structure - Example TRACEABILITY!!!!! Identifier Test001 Test case creator Oana FEIDI Version 0.1 Name of test case Verify that an error message appears when entering invalid values Identifier of requirement - Purpose To verify that an error message appears when entering invalid values, such as non-integers, chars or strings. Dependencies None Test environment Java 1.5.0 installed on the PC Initialization Run the program so that the UI panel appears Finalization Close the UI panel Actions In the UI panel enter the following data, in the corresponding field: a = 99, b = 1, c = !a# c Click "Verifica" button. Input data a = 99, b = 1, c = !a# c Expected result The following error message is displayed, written in red italic: "Valorile date nu se incadreaza in intervalul specificat."

8. Exercise Create test cases for solving the following equation: a * x * x + b * x + c = 0 a, b, c real numbers [-150, 10] The following are displayed in a pop-up x1, x2 the numbers If the selected numbers are not part of the interval the following error message is displayed "Error: invalid values.“ If a=0, the following error message will be displayed: “Not a quadratic equation. The coefficient a can not be zero.” Test it at the following link: http://id.mind.net/~zona/mmts/miscellaneousMath/quadraticRealSolver/quadraticRealSolver.html

9. Test case Start Functional test development Run tests Test OK? Coding no No more changes to TC yes End yes no Start Run tests 100% test completeness criteria reached? Add missing test cases no End yes Coding We need a combination between structural and functional
