如何使用正则表达式从黄瓜功能文件中提取特定场景

Question

I have a cucumber feature file that contains multiple scenarios and each has a different And. I am using Java regex to parse the file and want to pull out a specific scenario based on the text in the And.

For example:

Feature: testing stuff

Scenario:

lady swallows fly Given a lady and lady swallows a "fly" then lady lives

Scenario:

lady swallows spider Given a lady and lady swallows a "fly","spider" then lady lives

Scenario:

lady swallows everything Given a lady and lady swallows a "fly","spider","cat","dog","cow" then lady Dies

Scenario:

lady swallows everything except the dog Given a lady and lady swallows a "fly","spider","cat","cow" then lady Dies

I want to pull out the scenario that contains dog and dump it in a separate file. In my real life dog=account number and associates to multiple SQL extracts which are auto-loaded into a local database. This is a single scenario, in a single feature file, which is one of hundreds. So it's not a simple case of using @run at the top of the scenario. I am actually extracting the scenario and associated files so they can be put in a sandbox.

The regex that I have so far is:

.*?dog.*Scen

but that selects from the first instance of Scenario into the Scenario beyond what I want.

Instead I want to pull out the group:

Scenario:

lady swallows everything Given a lady and lady swallows a "fly","spider","cat","dog","cow" then lady Dies

Does anyone know how I can pull out that group?

Answer 1

If scenarios are delimited by \\n, try with:

^[^\n]+\bdog\b[^\n]+

if it is contiuous string, try with:

(?=Scenario).+?\bdog\b.+?(?=Scenario|$)
