4 CSE 2102 CSE 2102 Unit and White-Box Testing  Myriad of Products Available  junit junit.sourceforge.net/  Objective-C OCUnit cocoadev.com/wiki/OCUnit  Check for C check.sourceforge.net//  C/C++  MS Test for Visual Studio  Mobile Platforms  Titanium Recommends jsunity (Javascript)  Sensa Touch (Selenium, CasperJS, Siesta)

5 CSE 2102 CSE 2102 Unit and White-Box Testing  Also Includes General Testing of Capabilities  Assume that GUIs are Working Correctly  Now, Test Particular Feature Under Different Cases  CT Insurance – Renew Licenses on Periodic Basis  Scan Batches of Submitted Renewals  Renewal Form(s) + check(s)  Need to Test all Possible Combinations  Does System Work as Expected

6 CSE 2102 CSE 2102 Testing Producer Licenses

7 CSE 2102 CSE 2102 Testing Producer Licenses

8 CSE 2102 CSE 2102 User Interface Testing  Extensive Tests of Business Function and Logic  Utilized Business Process Logic  Often Provide by Domain Expert  Does Graphical User Interface Behave as Expected?  Is Each Screen Sufficient?  Are Screens Correctly Linked?  Are Data Entries Checked for Validity?  No illegal dates  Only numbers in zips and phone numbers  Only valid states  Consistency of State and Zip Code?  Do Required Minimums work?  Think about all you do when you use a web site!

9 CSE 2102 CSE 2102 User Interface Testing – Varies by Domain  E-Commerce  Focused on correctly Registering User, Processing an Order, Account Maintenance, etc.  Mostly Mouse/Keyboard Oriented  Gaming  Checking that all of the buttons (on touch screen) and/or options work correctly  Check to be sure there is consistency in placement across multiple screens  Mobile Apps  Linkages to other Apps (Facebook, etc.)  Checking individual screens, order of screens  Minimums need to be able to complete a screen to submit or go to the next screen

21 CSE 2102 CSE 2102 Black Box Testing  Treat Class, Procedure, Function, as a Black Box  Given “What” Box is Supposed to Do  Understand its Inputs and Expected Outputs  Execute Tests and Assess Results  Formulate Test Cases Based on What Program is Supposed to Do without Knowing  Programming Paradigm (OO, Functional, etc.)  Code Structure (Modularity, Inheritance, etc.)  No Access to Code  Usually Testing Software Engineer Speciality Class Procedure Function Inputs Expected Outputs

22 CSE 2102 CSE 2102 Black Box Testing for PHA  If PHA as Deployed App, what would you Test?  Testing when User has MSHV Account? w/o?  Testing Creation of New Medication  Create, Store, Logoff, Logon and see  After Create/Store, logon to MSHV Directly  Testing Entry of Information on Condition  Different Conditions  Can you Check these in MSHV?  Testing Entry on Exercise  Create, Store, Logoff, Logon and see  After Create/Store, logon to MSHV Directly  What Else Might be Tested?

23 CSE 2102 CSE 2102 Black Box Testing in CSE4940  Senior Design Project Sequence  Have Teams Exchange “Compiled Code”  Each Team Provide Test Cases/Scenarios  What are Objectives of Testing Engineers?  Run All Tests Given  Tweak Tests  Try to Break “Code”  Crazy Input  Unexpected Actions  One Important Tool to Assist in Testing:  Screen Capture and Annotation  Available Packages:  or soft.com/products/screenhunter_free.htm

24 CSE 2102 CSE 2102 General Performance Testing  Focus on the Actual Performance of Code  Specific Portions of Code  Sorting or Searching Algorithms  Key Time Critical Functional Capabilities  Role of Database  Explore Volume of Information from Database  Explore Concurrent Access to Database  Interactions Across Network  Explore Potential Bottlenecks in Network Traffic  Examine Potential Issues Across Hardware Platforms  Overhead Regarding Logging/Transaction Tracking  Including Actual Calls to System Clock in Code  Often Consider a Software Architecture View
