How to run multiple specific RSpec tests?

You can use the following syntax to run your specs for multiple files:

rspec path/to/first/file path/to/second/file

You could use the rspec --only-failures option which will only load and run spec files with failures.

Update: As @Grzegorz mentioned in the comments, you have to run all of them first and this command will give the failures from the last run.
