1TSI-11/02 Putting NATURAL to the Test Presented by J. Wayne Lashley Group Leader, Consulting and Technical Sales Treehouse Software, Inc.
2TSI-11/02 TSI Company background Enterprise NATURAL development today Categories of testing Testing tools Conclusion Agenda
3TSI-11/02 Company Background Established in 1982 27 Personnel Leading provider of systems software products and consulting services for Software AG customers Over 500 customers Worldwide presence
4TSI-11/02 Enterprise NATURAL Development Today Do more and do faster with less Wear many hats: analyst, designer, coder, tester, DBA, guru… Maintain unfamiliar, undocumented systems Adapt legacy systems to new technologies Work in teams of varying skill levels –People without ADABAS/NATURAL skills –Contractors
5TSI-11/02 Categories of Testing Unit Integration Performance/Load/Stress System Regression/Maintenance User Acceptance Documentation
6TSI-11/02 Unit Testing Module-oriented Parallelizable White box approach Stubs and drivers (Construct sites have advantage)
7TSI-11/02 Integration Testing Test units as a whole structure Discover interface errors Incremental build-up
8TSI-11/02 Performance/Load/Stress Testing Oriented to tested integrated system Test performance under various load conditions, including extreme Monitor resource usage
9TSI-11/02 System Testing Oriented to tested integrated system Exercise all required functions Verify completeness of functions and testing strategies
10TSI-11/02 Regression/Maintenance Testing Identify where changes have resulted in unintended behavior or new errors Comparative in nature Defined test cases
11TSI-11/02 User Acceptance Testing Workflow scenarios Validate against user manuals and documentation Identify cumulative errors
12TSI-11/02 Documentation Inventory of test cases, scripts and results Metrics Training materials Manuals

"name": "36TSI-11/02 Debugger Concepts Interactive (difficult for testing batch) Breakpoints and watchpoints Test environments Invoke at any time (%
41TSI-11/02 NATPAGE Concepts Interactively capture screen contents Capture sequence of screens or individually Playback is not execution Before/after comparisons useful for regression testing
42TSI-11/02 NATPAGE Terminal Control Commands %PActivates NATPAGE and captures contents of the current screen and all subsequent screens. %IActivates NATPAGE and captures contents of the current screen. %OTerminates NATPAGE. %SResumes NATPAGE. %EDisplays the screens captured with NATPAGE.
51TSI-11/02 Recording - Concepts Capture keystrokes and inputs Playback actually executes NATURAL objects Film mode and background (non-display) mode Creates “source” member in NATURAL library Can invoke recording during another recording (concatenation)
52TSI-11/02 Recording - Terminal Control Commands %B=libnameSpecify NATURAL library to capture recording “source”. %BnameActivate recording. %BTerminates recording. %AnamePlay back recording. %G[ON|OFF]Switch between background (default) and film mode.
61TSI-11/02 PROFILER for NATURAL NATURAL Quality Assurance and Testing Tool
62TSI-11/02 PROFILER Overview Quality Assurance and Testing Tool for developing/improving NATURAL objects and applications Monitors the execution of each statement within a “running” NATURAL object Comprehensive and flexible reporting Easy-to-use "tool-like" user interface Online and batch usage
63TSI-11/02 PROFILER Features Can be run in background with or without the knowledge of the user Only impacts the user who has started PROFILER Negligible overhead to NATURAL
86TSI-11/02 How does PROFILER work? NATURAL PROFILERPROFILER Statistics DATABASE PROFILER Standard Reporting PROFILER Enhanced Reporting PROFILER stats file (FUSER) PROFILER Enhanced Report File Standard Reports Custom Reports.
87TSI-11/02 PROFILER Roles Quality Assurance –Identify untested code –Report the percentage of an application tested Testing –Find weaknesses in test data and procedures Debugging –Find which statements are actually being executed, how often, and at what cost
88TSI-11/02 PROFILER Roles (cont’d) Performance Analysis –Identify expensive database accesses –Identify problem code, inefficient code, and poor application/object design Evaluation –Assess the impact of application or database changes Documentation –Test case execution and coverage –Testing metrics and participants
89TSI-11/02 PROFILER Roles (cont’d) Education –Gain insight into NATURAL’s internals –Evaluate NATURAL statement efficiency –Learn how an application works Application Analysis –Visual aid to verify application and programmatic flow
90TSI-11/02 The Treehouse Products Solution Category ProductsBusiness Need Data TransfertRelational, tRelational PC, DPS Easy access to ADABAS data for data warehouse, business intelligence and other off-the-shelf Internet and intranet applications Data IntegrationFKS IIIntegrating applications and data within the enterprise or between business partners Performance Management TRIMBetter performance from ADABAS and NATURAL applications DevelopmentCHART, PEEK, PROFILER, N20 Lower cost to support and enhance existing NATURAL applications Change Management N2O, N2O/3GLAbility to track and manage changes to business- critical NATURAL applications and ADABAS installations SecuritySECURITRE, AUDITREAbility to manage security for ADABAS and NATURAL Applications under ACF2, TOP SECRET, or RACF Database Utilities ADAREORG, ADASTRIP, AUTOLOADER, QDUMP Tools to increase the productivity of limited DBA resources Mainframe Emulators SEDIT, S/REXX, S/REXX Debugger Mainframe XEDIT and REXX emulators for UNIX and Windows users
92TSI-11/02 PEEK Product Overview ADABAS file browsing utility Easily find, examine, and optionally modify the data in an ADABAS file All of the data in a file is accessible – few keystrokes – virtually any order desired NATURAL application that issues direct calls to ADABAS Files may be read using Histogram, Read Logical, Read Physical, Read by ISN, Find, or Get ISN List commands by any desired keys
93TSI-11/02 CHART Product Overview NATURAL application analysis and documentation tool Draws program calling structures, using source code All other objects detected are drawn in an easy-to-read format - a CHART Excludes object types from the CHART “Suppress” objects from “expansion” Can be used on-line or in batch Export charts to Microsoft Visio
94TSI-11/02 N2O Product Overview NATURAL Change Management with 3GL Support, Project Tracking and N2OSCAN Migrates NATURAL objects, PREDICT objects, and SYSERR messages N2O/3GL migrates members stored in LIBRARIAN, PANVALET, ENDEVOR, or MVS PDSs Project Tracking maintains information about organizational activities N2OSCAN processes the source of NATURAL objects, scanning for strings over a user-specified object/library range
95TSI-11/02 TRIM Product Overview Performance, Tuning, Monitoring for ADABAS and NATURAL Installations Menu-driven Real-time Monitor Menu-driven NATURAL Monitor Parameter driven control and reporting features Assists: -DBAs -Data Analysts -Application Programmers
96TSI-11/02 TRIM Product Overview While ADABAS is active -Dynamic Control and Security (UEX1) -PRESUM logging summarizations -Selected detail command logging -On-line, Real-time Monitor (logging not required) -Hardcopy Nucleus Session Statistics (logging not required) -NATURAL Program Monitoring Not requiring an active database -PRESUM data reporting -Detail Command Log (CLOG) reports -Protection Log (PLOG) reports
97TSI-11/02 AUDITRE Product Overview Standardized ADABAS/NATURAL auditing facility Simple, powerful, valuable Parameter driven reporting features Assists: -IT Management -DBAs -Applications and Systems Analysts -Application Programmers -EDP Auditors -End Users
98TSI-11/02 In Conclusion… Range of testing categories and techniques requires a range of tools NATURAL provides a rich testing toolset but still room for third parties to add value Leveraging the right tool for the job helps meet the demands on today’s enterprise NATURAL developer
