Scale data-driven testing: a data file per test case

Running a batch of test cases together used to mean one data file for the whole batch, shared across every case whether it fit or not. Now each case brings its own.

• Attach the file to the case, not the batch: every test case in a run carries its own data source.
• Dozens of scenarios, one launch: run a large batch where every case pulls from its own file, all in a single execution.
• No manual wiring: skip hand-building iterations to fake per-case data, the platform does it natively.

This is what makes data-driven testing scale: a batch of a hundred cases can now mean a hundred different data sets, not one shared compromise.
