Integration Tests

In order to cover the new functionality, making sure the implementation actually works, a couple of new Integration Tests were added under the test/integration/component directory:

• test_vpc_offerings.py
  • That's an existing test, but it has been updated in order to cover the following:
    • Redundant VPC offering creation;
    • Create a Redundant VPC using the newly created offering
• test_vpc_redundant.py
  •  That's a new test, which will check the new features of the CloudStack Virtual Private Clouds. It does the following:
    • 1st Round of Tests
      • Creates a Redundant VPC
      • Creates 2 tiers
      • Creates 4 virtual machines, 2 per tier
      • Acquires 4 public IPs
      • Create port forwarding rules to open port 22, per IP, and assign to each virtual machine
      • SSH into the virtual machines
      • Check it succeeds
    • 2nd Round of Tests
      • Stop the Master router
      • Check the the Backup router becomes Master
      • SSH into the virtual machines
      • Check it succeeds
    • 3rd Round of Tests
      • Delete all port forwarding rules
      • SSH into the virtual machines
      • Check that it doesn't succeed
    • 4th Round of Tests
      • Start the stopped router
      • Check that we don't have 2 routers as Masters
      • Add all port forwarding rules
      • SSH into the virtual machines
      • Check it succeeds

Running the tests

• test_vpc_offerings.py

  • nosetests --with-marvin --marvin-config=[marvin_configuration_file_path] -s -a tags=advanced,required_hardware=false test_vpc_offerings.py

• test_vpc_redundant.py

  • nosetests --with-marvin --marvin-config=[marvin_configuration_file_path] -s -a tags=advanced,required_hardware=true test_vpc_redundant.py

When running the "test_vpc_offerings.py", the required_hardware flag should be set to false. The test will only create the offering and a Redundant VPC, no further tests will be done (e.g. create VMs, etc).

However, concerning the  "test_vpc_redundant/py", it does need the required_hardware flag to be set to true.
