result

Sometimes it can be useful to look at the information returned by the "run" command. For this we use the "result" object.

Example 1

In this example we run the "hostname" command on the machine and capture its output using "result". We'll use that value to make sure there isn't a user named as host name.

group "Using result object" do
  # Capturing hostname value
  run "hostname"
  hostname = result.value

  target "No #{hostname} user"
  run "id hostname"
  expect_none hostname
end

Example 2

When we are debugging our test and we want to see the content of the "result" object on the screen, we will use result.debug.

group "Checking users" do
  users = ["root", "vader"]

  for name in users do
    target "Exists username #{name}"
    run "id #{name}"
    result.debug
    expect "(#{name})"
  end
end
