Why test data?
If your recorded journey submits forms (login, search, booking), every virtual user needs its own values. Pick one:
- Synthesise — Contexta generates realistic rows for each field automatically.
- Load — upload a CSV and map its columns to the fields.
Data is treated as single-use: the smoke check consumes a few rows and the main load uses a disjoint set, so a value (e.g. an account) is never reused across the run. You must answer the data question before the test will dispatch.
