This plugin has the following options:
Do force a blank linesbetween steps block:
Given the following block:
Given some context
And some other context
When I do something
Then I should have a resultThe default output will be the same as the input (no blank lines).
If you set this option to true, it will force a blank line between the context block and the action block:
Given some context
And some other context
When I do something
Then I should have a resultIf you already have a blank line in your input, it will be kept as-is (event with this option set to false).
If you have more than one blank line, it will be reduced to a single blank line.
default to false
If false, all escaped backslash will be transformed to simple backslash : \\ → \
If true, all backslash will be espaced : \ → \\
This option may be due to the parser (see issue) and is here because of an inconsistence between the gherkin reference, that said that:
if you need a
\, you can escape that with\\.
and the tooling that accept unescaped \, including the cucumber parser used under the hood.
You may want to check your code base and be consistent : if you use simple backslash, keep the default option, if you escape all backslash, then set this option to true.
