Frozen string failure in output

[viraptor]

Summary

A random run ended up with:

can't modify frozen String (RuntimeError)
/project/path/vendor/bundle/ruby/2.3.0/gems/cucumber-3.1.0/lib/cucumber/formatter/html.rb:571:in `snippet'
/project/path/vendor/bundle/ruby/2.3.0/gems/cucumber-3.1.0/lib/cucumber/formatter/html.rb:293:in `extra_failure_content'
...

Possible Solution

This error doesn't seem to make any sense.

• if the string is appended there, the converter is NullConverter
• in that case highlighted == raw_code
• raw_code comes from snippet_for
• snippet_for returns an array

Unless something, somewhere overrides the behaviour, this can't happen 🤔But this project doesn't override anything in related classes.

Steps to Reproduce (for bugs)

Unfortunately the ordering is random and I can't reproduce it.

Your Environment

• Version used: 3.1.0
• Operating System and version: Ubuntu trusty, ruby 2.3
• Link to your project:

Do you have the Syntax gem installed? We patched this specific issue a little while ago, but it hasn't yet been released.
#1287

[viraptor]

No, I don't have the Syntax gem

[xtrasimplicity]

@viraptor I've created a PR with the intention of preparing a new release in the next few weeks.

In the meantime, I would recommend either temporarily monkey-patching Cucumber::Formatter::Html.snippet as per #1287 or installing the Syntax gem. Once we've released a new version of cucumber-ruby, you will be able to remove the monkey patch or uninstall the Syntax gem. :)
