CICS-Dbg1 Testing and Debugging Programmers responsibility that program works correctly! Can write program incrementally You must test anything that the user may enter on every screen High–Low ranges of data entered Invalid entries – when feasible

CICS-Dbg2 Types of Testing Unit Test Tested by itself to verify performance Correct screens displayed Field edits working correctly Files updated correctly Usually done by programmer

CICS-Dbg3 Types of Testing Concurrency Test Run concurrently on several terminals Verify multiple executions - no interference Usually need help for this testing Verify record ‘locks’ (if used) Verify ‘busy’ message (if used)

CICS-Dbg4 Types of Testing Integration Test Run with other programs Verify the program works as part of system Can also find problems with app design  Screen Formats  PF key uses and layouts  Color coding used, etc.

CICS-Dbg5 Types of Testing Regression Test Verify functions not changed still work Very time consuming Entire original test usually repeated 70+ Percent is maintenance (not NEW!) Often done hurriedly with poor results

CICS-Dbg6 Test Environment Usually separate CICS region Relaxed Security Create own table entries Create test Data Sets Access to CICS debug aids  CEMT, CECI, CEDF, CEDC Change management software

CICS-Dbg7 The Test Plan Try and test everything! Maximum and Minimum Values Required Fields Missing Fields Default Values Data Set Access and Updates ‘Clean Up’ when Finished!

CICS-Dbg8 Test Steps Test the MAPSETS CECI transaction – SEND MAP Verify items on checklist Page 201 Program, MOVE ALL ‘X’ to fields, SEND MAP Test Program with VALID data Test ‘normal’ functions and defaults Test Program with INVALID data Most time consuming making up data Test all edit rules and defaults

CICS-Dbg9 CEDA (For Table Updates) CEDA DI G(group) [ Display Group] (where nn is last two digits of your ID Find similar entries and type following: COPY AS(VIS0nn) - MapSet COPY AS(VIP0nn) - Program COPY AS(V0nn) - Transaction ID Alter – Change to new program name! COPY AS(NAMADDnn) – VSAM File Alter – Change DSN and verify Settings CEDA I G(group) [Install Group]

CICS-Dbg10 CICS Transactions for Testing CEMT – Master Terminal Transaction NEWCOPY Program / Map  Must do after each COMPILE!  CEMT I PROG(V*QQ) OPEN/CLOSE a Data Set  Needed for rebuilding a Data Set  CEMT I FI(V*QQ)  DELETE / DEFINE of VSAM Data Set

CICS-Dbg11 CEMT (Handy Transactions) Used for NEWCOPY after Compile(s) CEMT I PROG(VIP*QQ) Lists COBOL Programs CEMT I PROG(VIS*QQ) Lists Assembler (MAP) Programs CEMT I FI(*QQ) [For initializing files] Lists All Your CICS VSAM Files

CICS-Dbg12 CICS Transactions for Testing CECI – Command-level Interpreter Allows execution of Most CICS commands Can test MAP display Can store data in VARIABLES ALL CECI Variables start with ‘&’ Can modify (corrupted) Data Sets  READ UPDATE into &rec, then REWRITE!

CICS-Dbg13 CECI (For MAP Testing) CECI SEND MAP(‘VIDS0M1’) MAPSET(‘VIS0QQ’) [ERASE] MAPONLY Shows command before and after Can run most CICS Commands Can use variables! (Pages )

CICS-Dbg14 Debugging a CICS Abend ABEND = ABnormal END of Program Program encounters error CICS presents Abend Code to Program Program can handle with message Program can ignore – (CICS Abend) Over 300 Abend codes Only a few are usually handled

CICS-Dbg15 Abend Code Types Exceptional Conditions (AEI and AEY) File Not Open, Record Not Found, Etc. Program Checks (ASRA) S0C7, other program errors. Other (Misc) Abend Codes Cursor off screen, no map found, etc.

CICS-Dbg16 Execution Diagnostics Facility Same Terminal Checkout Mode ‘CEDF’ entered from clear screen Terminal Responds: EDF MODE ON Enter TRAN-ID of Program to debug Each CICS COMMAND is shown  Before execution and after execution  Status shown, NORMAL is Good! You can add ‘Extra’ CICS Commands

CICS-Dbg17 (Re)Build VSAM Data Files In CICS, Close Files - CEMT I FI(V*QQ) In TSO, RUN: VCUSTDS and VTAPEALL In CICS, Open Files – CEMT I FI(V*QQ) In CICS, Enter Customer(s), Tape(s) In CICS, Close Files (one more time) In TSO, RUN: VTAPEBX (Builds Index) In CICS, Open Files (For last time?)
