Rspec error cannot find matching line from backtrace

Question

I have written a group of 23 tests for my user model and all of them are failing with the following error: ``` Failure/Error: Unable to find matching line from backtrace ArgumentError: block not supplied ``` I have tried messing with different versions of capybara, rspec-rails, and growl, but to be perfectly honest, I really don't know what I'm doing here, and don't really understand the error. I would really appreciate help from anyone who could point me in the right direction. Here is a sample from my `user_spec.rb` file ``` require 'spec_helper' describe User do before @user = User.new(name: 'example', password: 'foobar', password_confirmation: 'foobar', email: 'example@example.com', description: 'Lorem ipsum dolor...') subject { @user } it { should respond_to(:name) } it { should respond_to(:email) } it { should respond_to(:password) } it { should respond_to(:password_confirmation) } it { should respond_to(:password_digest) } it { should respond_to(:description) } it { should resp…

Accepted Answer

The problem here is that you have not specified a block for the before method:

```
before @user = User.new(name: 'example', password: 'foobar', password_confirmation: 'foobar',
                    email: 'example@example.com', description: 'Lorem ipsum dolor...')
```

should be:

```
before do
  @user = User.new(name: 'example', password: 'foobar', password_confirmation: 'foobar',
                    email: 'example@example.com', description: 'Lorem ipsum dolor...')
end
```

Admittedly the error message is not very helpful here. The Ruby interpreter can't always pinpoint the exact line in the program that an error is raised, e.g. when there is a Stack level deep error' but I'm not sure why it cannot in this case.
