Run Rspec on VS Code

Run rspec on VS Code

OK. I solved it!
My fault is setting wrong value to program.
Program must be rspec path.

...
{
  "name": "RSpec - all",
  "type": "Ruby",
  "request": "launch",
  "cwd": "${workspaceRoot}",
  "program": "D:/Ruby/Ruby21/bin/rspec",
  "args": [
    "--pattern",
    "${workspaceRoot}/spec/**/*_rspec.rb"
  ]
},
...

Run bundle exec command Tasks in Visual Studio Code

Thanks to Hurelu in this post, who explains how shell commands are constructed using the definitions in tasks.json, I have been able to define a tasks file that can run both rspec and cucumber, using bundle's exec:

{
  "command": "bundle",
  "args": ["exec"],
  "tasks": [
    {
      "suppressTaskName": true,
      "taskName": "rspec",
      "args": [ "rspec", "${file}" ],
      "isTestCommand": true
    },
    {
      "suppressTaskName": true,
      "taskName": "cucumber",
      "args": [ "cucumber", "${file}" ]
    }
  ]
}

RSpec is the test command, so you can use Cmd+Shift+T/Ctrl+Shift+t to run the current file as an RSpec test.

Happy coding!

How to run a single RSpec test?

Not sure how long this has bee available but there is an Rspec configuration for run filtering - so now you can add this to your spec_helper.rb:

RSpec.configure do |config|
  config.filter_run_when_matching :focus
end

And then add a focus tag to the it, context or describe to run only that block:

it 'runs a test', :focus do
  ...test code
end

RSpec documentation:

https://www.rubydoc.info/github/rspec/rspec-core/RSpec/Core/Configuration#filter_run_when_matching-instance_method

How do I run debugger with the Rails run Spec extension?

Add pry-byebug to your gemfile and run bundle install

# Gemfile
gem 'pry-byebug'

Then, whenever you want to inspect a test, add binding.pry inside the test.

# some_spec.rb

it "is not behaving how I want it to" do
  binding.pry
  expect(my_var).to eq(some_val)
end
