rspec:tldr:dc5d6

The command "rspec ${filename1} ${filename2}" is used to run the RSpec tests written in Ruby for the specified files or file patterns.

• "rspec" is the command to execute RSpec, which is a testing framework for Ruby.
• "${filename1}" and "${filename2}" are placeholders that represent the names of the files or file patterns you want to test. These placeholders will be replaced with the actual filenames or patterns when running the command.

For example, if you have two test files called "spec/models/user_spec.rb" and "spec/controllers/posts_controller_spec.rb", you would run the command as follows:

rspec spec/models/user_spec.rb spec/controllers/posts_controller_spec.rb

This command will execute the RSpec tests defined in both test files and provide the test results and any failures or errors encountered during the testing process.
