Extraction naming consistency

[AntonioSun]

I know this is kind of nitty-picky, but hear me out:

groovy-jmeter/src/test/groovy/net/simonix/dsl/jmeter/factory/extractor/ExtractorFactorySpec.groovy

Lines 30 to 32 in 07b89a2

	extract_regex(variable: 'var_variable', expression: 'variable')
	extract_jmes(variable: 'var_variable', expression: '$..author')
	extract_json(variables: 'var_variable', expressions: '$..author')

I.e., both extract_regex and extract_jmes use variable and expression.
Yet, extract_json uses variables and expressions (both plural) instead.

I just feel that the plurals here don't make much sense, and the naming is not consistent.
However, I do understand that you might have many legacy code done this way.

Hi, the reason for that is the extract_json can have multiple expression and variables e.g.

extract_json(variables: ['var_variable1', 'var_variable2'], expressions: ['$..author', '$..book'])

but you if have only one variable and expression then you can use string only without []

extract_json(variables: 'var_variable', expressions: '$..author')

I would agree that we can split it into two so you can use variable/expression if you have only one and variables/expressions if you have multiple. But yeah I don't have strong opinion in that.

Oh, in that case, let it be then. Thanks for the explanation.
