What are Probes?

Table of Contents

BiG EVALs testcases are based on a simple three-step concept. The first step is about taking one or multiple probes from datasources.

Probes are pieces of data in different shapes. They can either be a scalar value, a list or a full dataset with multiple rows and columns. The datasource-queries’ results can be shaped by extraction-methods.

The probes are the input for the validation-algorithms (testmethods) and are either to be checked by the algorithm (e.g. comparing multiple probes against each other), or they control the algorithm (e.g. iterating through a list of sales-teritories to run the testcase once for each of them).

The probes of a testcase are defined within the Probes-register in the testcase-editor.
