Testing "Capybara element not found"

I have implemented a model/views/controllers for a model and created cucumber testing which was successful. Then I implemented solr search for the records then some of tests getting failed which have no connection with solr search
Could you please provide me with some solution.

The error is like “Capybara element not found”

Thanks in advance

As a first step roll back your source control system (git or whatever)
to the version where the tests worked and check that they still work.
That will tell you whether it is a change to the system or to the
source that has caused the problem.
