It is a hybrid between Use Case and Sequence Diagram
In case of simulations, before it was ready to be installed, many test runs are done to check its robustness. Trace driven simulation is getting the actual data from a real experiment and feeding it to the simulation. The disadvantage is every time the experiment has to be done which is a tedious job, advantage is absolute results.
The term of "Test Case" is a legal term. A test case is a legal case which sets precedent for other cases which have the same question of law involved.
The word robustness has one meaning. The definition of this word is, "the property of being strong and healthy in constitution." This word is an add on from the word 'robust.'
Being very strong and excellent health.
By preparing test cases we can test an algorithm. The algorithm is tested with each test case.
A test case represents the compilation of the test scenario, test script and expected results. Whereas the test script only represents the description of the input used to validate the assertion captured in the test requirement.
Test case is a smallest unit of test to test the specific functionality. Test case have pre and post condition, actions, steps and expected result. Test script is a set of statements to test the positive scenario of the functionality
Robustness has been defined by the Food and Drug Administration as "the degree to which a software system or component can function correctly in the presence of invalid inputs or stressful environmental conditions."

A test case is a set of conditions to determine whether an application is working properly. A test suite is a group of test cases merged together to get an overall outcome. Test data is used to analyze results.
A test case involves an actual company or event that occurred. A test scenario uses a fake event that could occur. A test scenario is a simulation where the parameters can be changed to manipulate the results.
