RSpec doesn’t have any built-in features for what you’re asking for, but
it’s easy enough to write it yourself:
require 'timeout'
module WaitHelpers
def wait_until(timeout)
timeout_time = Time.now + timeout
loop do
sleep 0.1
return if yield
raise Timeout::Error if Time.now > timeout_time
end
end
def wait_until_port_available(container)
wait_until(10) do
container.port.available? # or whatever the logic to check port
availability is
end
endend
RSpec.configure do |rspec|
rspec.include WaitHelpersend
RSpec.describe "A docker container" do
before do
@container = Docker::Container.create
@container.start
wait_until_port_available(@container)
endend
