FICTIONAL PRACTICE ONLY - NO REAL DATA
Month 11 · Test exceptions and compare evidence

Downloaded worksheet. Use only invented case data. The accompanying CSV contains no formulas; calculate and explain values yourself. Work locally. Do not send customer information or enter passwords, account details or identity documents. This file does not enroll, certify, verify graduation or grant a discount.

Reading:
Define test input and expected output first. Include missing and repeated inputs, and check that no unauthorized action is confirmed. Timing comparisons require equivalent tasks and conditions.

Fictional case:
Fictional test: before, five tasks took30 minutes with2 corrections; after, five comparable tasks took25 minutes with1 correction. Another case is incomplete.

Local activity:
Create tests for normal input, missing data, unknown product and duplicate. Calculate timing/correction differences and write a limited conclusion.
