12 Time-Boxed Sessions Define the focus area Series of time-boxed Session 2 HRS Capture information you need to convey Capabilities; Limitations

13 Essential Elements Learning Design Execution Interpretation

14 Examples - Learning Activity Study competitive products Research the history Identify missing information Interview users, developers Review documents Specifications, other authoritative documents Risk, Failure history

15 Examples - Design Activity Charter Decide what you will work on How you will work Develop supporting test data Map staff skills to tools/techniques Map test techniques to test ideas Design Test Scenarios

16 Charter Your Explorations Explore (target) with (resources) to discover(information)

17 Good Charter Offers direction without over specifying test actions Too Specific Explore editing last name with a value of O Brien Too Broad Explore system security with all the hacking programs Explore inputs fields with SQLInjection attacks to discover security vulnerabilities

18 Context Matters Inattentional blindness

19 Important Context Factors Who are the stakeholders What the goals and quality criteria What is in the product How could it fail Potential Consequences of failure How to trigger the fault

20 Examples - Execution Activity Configure the product Get distracted from one of action in order to produce an unanticipated new idea Pair testing Create & debug an automated series of tests Run and monitor the execution

21 Making the Invisible Visible Using Process Monitors for CPU monitoring Monitor File system activity Using Developer tools in Browser Consoles & Log files

22 Discover Interesting Variables Obvious Variables Integer, Date, Strings Subtle Variables

23 Interesting Variations Zero, One, Many 0 record found or 1 records found Too Many Too many connections Too Few Create conditions with too few things than it is expected

24 Interesting Variations Files, Size & Storage Geographic Locations Time zone, Postal address Formats Date, Address, Phone, SSN, Postal Code Depth

26 State and Transition Externally generated events System generated events Passage of time State transition

27 Interrupt Clicking user Controls Logging Out Session timeout Kill the process Disconnecting the machine from the network

28 Examples - Interpretation Activity Determine whether the program passed or failed A mechanism for determining whether a program passed or failed is called a Oracle Determine which oracle is useful for a given test or test result

29 Evaluate Results Identify the Never and Always Condition Identify the external resources Identify useful approximation
