next and continue, see:

From: .../spec/models/task_spec.rb @ line 17 :

    12: 
    13:   describe "is not taskable" do
    14:     let(:task) { build(:task) }
    15: 
    16:     it {
 => 17:       binding.irb
    18:       expect(task.taskable_id?).to be(false)
    19:     }
    20:   end
    21: end

irb(#<RSpec::ExampleGroups::Task:...):001> next
Loaded debug-1.8.0
(rdbg:irb) next
[13, 21] in ~/.../spec/models/task_spec.rb
    13|   describe "is not taskable" do
    14|     let(:task) { build(:task) }
    15| 
    16|     it {
    17|       binding.irb
=>  18|       expect(task.taskable_id?).to be(false)
    19|     }
    20|   end
    21| end

You can't. IRB is a REPL, but not a debugger.

Use a debugger instead, like byebug:

Usage (instead of typing binding.irb):

byebug

Then to go to the next line, type:

next
