NAME

TAP::Harness::Remote::EC2 - Run tests on EC2 servers

SYNOPSIS

prove --harness TAP::Harness::Remote::EC2 t/*.t

DESCRIPTION

Based on TAP::Harness::Remote, this module uses your running Amazon EC2 instances (http://amazon.com/ec2) to run tests against, instead of a preconfigured list of hosts.

USAGE

Configuration is much the same as TAP::Harness::Remote, except the configuration file lives in /.remote_test_ec2 -- see "CONFIGURATION AND ENVIRONMENT".

METHODS

load_remote_config

Loads and canonicalizes the configuration. Writes and uses the default configuration ("default_config") if the file does not exist.

hosts EC2 [, STATUS]

Returns an array of Net::Amazon::EC2::RunningInstances objects which match the ami type specified in the config file, and whose status matches the given STATUS. STATUS may be either a string, or a regex; it defaults to "running".

EC2 should be a valid Net::Amazon::EC2 object.

wait_pending EC2.

Waits until all hosts in the "pending" state have started. EC2 should be a valid Net::Amazon::EC2 object.

CONFIGURATION AND ENVIRONMENT

The configuration is stored in ~/.remote_test_ec2, and is mostly identical to the configuration of TAP::Harness::Remote (see "CONFIGURATION AND ENVIRONMENT" in TAP::Harness::Remote), with the following differences:

  • The hosts parameter is ignored, and produces a warning if present.

  • The access_key amd secret_access_key parameters are required, to be able to query the Amazon EC2 interface and determine the running EC2 hosts. You can find your access keys at https://aws-portal.amazon.com/gp/aws/developer/account/index.html?action=access-key

  • There is an optional ami parameter, which limits which AMIs will be used to run tests; it also lets the harness start the instances if there are not enough running.

  • There is an optional instances parameter, which specifies the number of AMI instances to run tests on. Defaults to one.

  • There is an optional instance_type parameter, which controls the type of instances to create; possible arguments are m1.small, m1.large, and m1.xlarge. The default is m1.xlarge.

DEPENDENCIES

Net::Amazon::EC2, TAP::Harness::Remote

BUGS AND LIMITATIONS

The default perl installed Amazon's provided EC2 images is extremely slow (about 4x slower than a clean, optimized build). We thus strongly suggest you compile your own.
