“Rubbish in = rubbish out” applies to many things in life from diet, to building and cooking, but especially to testing. It is all very well if you are doing negative testing, but most testing is about trying to prove things work the way they should, and that needs good test data.
1. Show you what changed, field by field, record by record, including deletes. It will do this wherever there are Db changes, not just where you say to look.
2. Use rules across the data to ensure that what happened was correct, even accumulating values from other files.
3. Cross-check against other versions of files or previous test runs.
If you have an IBM i – or maybe you still call it AS/400 or iSeries – you have data, important data. TestBench gives you the tools to ensure that important data stays right and avoids errors leaking into production.
TestBench has your back.
