🕸 Stub Dynamic URLs with Regex Patterns​

When your application makes HTTP calls to URLs that include dynamic segments—like user IDs or timestamps—you can use regular expressions in WebMock to stub them without enumerating every possible URL. This approach keeps your stubs concise and maintainable. Simply pass a Ruby Regexp to stub_request to match any URL fitting the pattern.

require 'webmock/rspec'

# Stub any GET request to /users/<number>/details
stub_request(:get, %r{https://api\.example\.com/users/\d+/details})
  .to_return(
    status: 200,
    body: '{"id":123,"name":"John Doe"}',
    headers: { 'Content-Type' => 'application/json' }
  )

# Example call
response = Net::HTTP.get(URI('https://api.example.com/users/456/details'))
puts response #=> {"id":123,"name":"John Doe"}
