How to call a linux command from rspec file

Question

I am having a rspec ruby file named test_spec.rb . I want to add below command inside the file so to make it run when I run the rspec file.

exec("sudo gsutil cp test_object.txt gs://sample-bucket1")

But when I am running my code as soon as above command runs it stops the further execution. How can I prevent it.

Below is my Rspec code.

A=C.new

context "Bucket Resource : " do

#setup  data

before('The Original should create object') do

        #some code here 
        exec("sudo gsutil cp test_object.txt gs://sample-bucket1")
  end


#Positive Test cases

 describe "The Original should create object" do
      it  "Should execute successfully and return an instance " do
                 #define namevar
                 entity = "[email protected]"
                 #define build params
                  build_params = {
                        entity: "[email protected]",
                        role: "OWNER",
                  }
         expect(A.create_instance(build_params)).to be_an_instance_of(B)
        end
 end

after('The Original should create object') do
    #some code here
end
end

After running the above code, after hook is not called.

What actually happens when you run that linux command? Doe it fail silently or is there an error? — max pleaner

exec replaces your process with the given command, so it's actually the expected behavior. You might want to use `...` or system instead. — Stefan

There is no error, it just stops executing. Actually I found other way. — Vivek

You can use back tick for this inside your rspec file:

`sudo gsutil cp test_object.txt gs://sample-bucket1`
