BOSH Acceptance Tests

The BOSH Acceptance Tests are meant to be used to verify the commonly used functionality of BOSH.

BATs describe BOSH behavior at the highest level. They often cover infrastructure-specific behavior that is not easily tested at lower levels. BATs verify integration between all BOSH components and infrastructures. They run against a deployed Director and use the CLI to perform tasks. They exercise different BOSH workflows (e.g. deploying for the first time, updating existing deployments, handling broken deployments). The assertions are made against CLI commands exit status, output and state of VMs after performing the command. Since BATs run on real infrastructures, they help verify that specific combinations of the Director and stemcell works.

Prerequisites

  • deployed BOSH director
  • installed BOSH v2 cli

Configure BATS

Required Environment Variables

Before you can run BAT, you need to set the following environment variables:

# path to the stemcell you want to use for testing
export BAT_STEMCELL=

# path to the bat yaml file which is used to generate the deployment manifest (see below `bat.yml`)
export BAT_DEPLOYMENT_SPEC=

# BOSH CLI executable path
export BAT_BOSH_CLI=bosh

# DNS host or IP where BOSH-controlled PowerDNS server is running, which is required for the DNS tests. For example, if BAT is being run against a MicroBOSH then this value will be the same as BAT_DIRECTOR
export BAT_DNS_HOST=

# the name of infrastructure that is used by bosh deployment. Examples: aws, vsphere, openstack, warden, oci.
export BAT_INFRASTRUCTURE=

# the type of networking being used: `dynamic` or `manual`.
export BAT_NETWORKING=

# the path to ssh key, used by OS specs to ssh into BOSH VMs
export BAT_PRIVATE_KEY=

# Run tests with --fail-fast and skip cleanup in case of failure (optional)
export BAT_DEBUG_MODE=

To enable OS tests set:

export BOSH_OS_BATS=true

Environment variables for the BOSH v2 cli

Provide all necessary variables for the BOSH cli to connect to the director, e.g.:

export BOSH_ENVIRONMENT=<director ip or alias to bosh-env>
export BOSH_CLIENT=<director username>
export BOSH_CLIENT_SECRET=<director password>
export BOSH_CA_CERT=<director ca cert content or path>

BATS manifest: bat.yml

Create bat.yml that is used by BATs to generate manifest. Set BAT_DEPLOYMENT_SPEC to point to bat.yml file path.

The 'dns' property MUST NOT be specified in the BAT deployment spec properties. At all.

Setup IaaS

AWS Setup

On EC2 with AWS-provided DHCP networking

Add TCP port 4567 to the default security group.

On EC2 with VPC networking

Create a bat security group in the same VPC the BAT_DIRECTOR is running in. Allow inbound access to TCP ports 22 and 4567 to the bat security group.

OpenStack Setup

Networking Config

Add TCP ports 22 and 4567 to the default security group.

Flavors

Create the following flavors:

  • m1.small
    • ephemeral disk > 6GB
    • root disk big enough for stemcell root partition (currently 3GB)
  • no-ephemeral
    • ephemeral disk = 0
    • root disk big enough for stemcell root partition (currently 3GB), plus at least 1GB for ephemeral & swap partitions

Running BATS

Some tests in BATs may not be applicable to a given IaaS and can be skipped using tags. BATs currently supports the following tags which are enabled by default (use --tag ~vip_networking to exclude them):

  • core: basic BOSH functionality which all CPIs should implement
  • persistent_disk: persistent disk lifecycle tests
  • vip_networking: static public address handling
  • dynamic_networking: IaaS provided address handling
  • manual_networking: BOSH Director specified address handling
  • root_partition: BOSH agent repartitioning of unused storage on root volume
  • multiple_manual_networks: support for creating machines with multiple network interfaces
  • raw_ephemeral_storage: BOSH agent exposes all attached instance storage to deployed jobs
  • reboot: reboot VM tests as part of cloud-check
  • changing_static_ip: configure_networks CPI method support [deprecated]
  • network_reconfiguration: configure_networks CPI method support [deprecated]

Here is an example of running BATs on vSphere, skipping tests that are not applicable. Execute the following inside the bosh-acceptance-tests directory:

bundle exec rspec spec --tag ~vip_networking --tag ~dynamic_networking --tag ~root_partition --tag ~raw_ephemeral_storage
You can’t perform that action at this time.
