1. 1 Questions? CSSE 490 - Requirements Steve Chenoweth Department of Computer Science & Software Engineering RHIT Session 9 – Wed, Aug 8, 2007 Below – From ID Ch 15 – Return on investment in usability testing – How many evaluators is the right number?

2. 2 Questions? Today Discuss the 2 assignments you just did. Next week’s assignment – The presentation. Acceptance testing – a quick review. Evaluating ID products. Usability testing. Inspections. Exam 2.

3. 3 Questions? The improved prototypes What was easy to follow my process suggestions? What was the toughest part? How much did it change? Does it feel “finished”?

4. 4 Questions? The improved user interface Did peer input help? Did you make other changes? How did coordinating with your peers go? Is your result useful?

5. 5 Questions? Next week’s assignment – The presentation Let’s look at it. You’ll be providing your peers in class with new information about testing: –How you’d do acceptance testing –How you’d do usability testing

6. 6 Questions? Acceptance testing – a quick review This was Ch 26 in the Req book. Key is your use cases -- It’s 1 use case  many test cases (Why?) For quality attributes – Create a test case based on each scenario you did What you present next week -- These should look like the outline of each test case. (Probably lacking some details.)

7. 7 Questions? What does a (short) acceptance test look like? This one’s from a senior project. It involves users, but doesn’t have to! It’s a “negative” test – note how it tests error conditions! Don’t do quite this much – do like an outline of this! How many?  See assignment Test Cases for Use Case: 4.1.1 - Start Page Test Case Id Scenari o DescriptionCondition: Entered all required information Expected Result 4.1.1.11Don’t enter any informationNoWarning for each required item not entered 4.1.1.21Don’t enter NameNoWarning 4.1.1.31Don’t enter Employee #NoWarning 4.1.1.41Don’t enter DeptNoWarning 4.1.1.51Don’t enter Phone Ext.NoWarning 4.1.1.61Don’t enter Email AddressNoWarning 4.1.1.71Don’t enter Purpose for Request NoWarning 4.1.1.81Don’t enter Project #YesContinue flow 4.1.1.91Don’t enter DateYesContinue flow 4.1.1.1 0 1Don’t enter request typeNoWarning ScenarioOriginAlternate Flow 1Home pageEnter information in start page, click “Continue”

8. 8 Questions? And what do usability tests look like? Pretty similar (since the above one was for a user activity). We’ll talk more about this tonight – Ch 14 in ID Two files of examples (which also could be considered acceptance tests), under Handouts: –sample_validation_test_cases.html and –TestCaseExample- SQAReadingAssessmentTestCase4_04092002.htm

9. 9 Questions? Today’s ID topics (includes usability testing) Ch 11: Design, prototyping and construction - Was “read on your own” Ch 12: Introducing evaluation Ch 13: An evaluation framework Ch 14: Usability testing and field studies Ch 15: Analytical evaluation ID slides are in separate files.

10. 10 Questions? Example we’ll use, once again, as a “vehicle” for class discussion today “Design a text messaging system for people to use as they drive their cars.” Here’s our guy: Left - Here’s the problem: Political consultant Daniel Cence says he is trying to curb the impulse to text-message and read his e-mails while he is driving, after having an accident while texting.
