Packer Black-Box Tests

This folder contains tests that test Packer using a black-box approach: packer is executed directly (with whatever is on the PATH) and certain results are expected.

Tests are run using Bats, and therefore Bash is required to run any tests.

Warning: Many of these tests run using AWS, and therefore have a real-world cost associated with running the tests. Be aware of that prior to running the tests. Additionally, many tests will leave left-over artifacts (AMIs) that you'll have to manually clean up.

Running Tests

Required Software

Before running the tests, you'll need the following installed. If you're running on Mac OS X, most of these are available with brew:

Bats
AWS cli for AWS tests as well as most of the components.
gcutil for Google Compute Engine tests.

Configuring Tests

For tests that require AWS credentials:

Set the following self-explanatory environmental variables:

AWS_ACCESS_KEY_ID
AWS_SECRET_ACCESS_KEY

For tests that test Google Compute Engine:

Set the following environmental variables:

GC_BUCKET_NAME
GC_CLIENT_SECRETS_FILE
GC_PRIVATE_KEY_FILE
GC_PROJECT_ID

Running

These tests are meant to be run one file at a time. There are some test files (such as the amazon-chroot builder test) that simply won't run except in special environments, so running all test files will probably never work.

If you're working on Packer and want to test that your change didn't adversely affect something, try running only the test that is related to your change.

$ bats builder_amazon_ebs.bats

Note: Working directory doesn't matter. You can call the bats test file from any directory.
