A template builder for dynamically generated executables intakes objects from a metadata repository and template components from a template component library. An interface receives user selections of a test data object from among the objects in the metadata repository and template component from among the template components in the template component library. The template builder builds a candidate script template with the selected template component(s) and customizes the candidate script template, using the selected test data object into a generated script preview. The interface displays the generated script preview, and upon execution of the generated script preview, displays results of the execution. If the user is satisfied, the candidate script template may be persisted and used in templated data tests or other templated computational tasks.
