Best Practices For Mainframe Testing
- Dry run of job: Doing a dry run of the job under test is always a smart idea. Empty input files are used for the dry run. This procedure should be undertaken for any jobs that are affected by the test cycle changes.
- Complete test task setup: The test task setup should be completed well in advance of the start of the test cycle. This will aid in the early detection of any JCL errors, saving time during execution.
- Set auto-commit to NO: Always set auto-commit to “NO” when accessing DB2 tables through SPUFI (the emulator’s option for accessing DB2 tables) to avoid unintentional updates.
- Confirm technical inventory: Don’t underestimate the importance of effective project management and solution architect support for your project. Typically, these projects focus on applications that have been critical to the business for a long time. Confirming technical inventory and obtaining test and use case data are the two greatest time and expense drivers for mainframe migration initiatives. Make sure that your expertise is available and invested in the project.
- Create required data in advance: It is considered best practice to create test data in advance of the test cycle and should be checked for completeness of the data.
Software Testing – Mainframe Testing
Mainframe testing is used to evaluate software, applications, and services built on Mainframe Systems. The major goal of mainframe testing is to ensure the application or service’s dependability, performance, and excellence through verification and validation methodologies, and to determine if it is ready to launch or not. Because CICS screens are custom-built for specific applications, the tester just has to know how to navigate them when performing Mainframe testing. Also, if the code in COBOL, JCL, or other languages is changed, the tester does not have to worry about the emulator being set up on the system.
