gpc-for-loop

A precompiler of GherKing to loop scenarios and scenario outlines to repeat them.

In the case of scenario outlines, it copies all rows of examples, resulting in iterator × rows number of scenarios when tests are run.

Usage

Identify scenario or scenario outline to be repeated and mark it with ${loopTag}(${i}) e.g. @loop(4).

The precompiler will then repeat this scenario or scenario outline for ${i} times, modifying its name according to the format.

Configurable variables and their default options:

Option	Default	Description
maxValue	10	Maximum value of iteration
tagName	'loop'	Tag used to mark scenarios or outlines to be repeated
format	'${name} (${i})'	Format of the scenario or outline name after repeating
limitToMaxValue	true	Whether higher iteration values than the max should be limited to the max or error should be thrown ( false )

See examples for the input files and output in the test/data folder.
