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 cloud infrastructure, 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.
Before running the tests, you‘ll need the following installed. If you’re running on macOS, most of these are available with brew:
AWS cli for AWS tests as well as most of the components.
gcutil for Google Compute Engine tests.
h1-cli for HyperOne tests.
For tests that require AWS credentials:
Set the following self-explanatory environmental variables:
AWS_ACCESS_KEY_IDAWS_SECRET_ACCESS_KEYFor tests that test Google Compute Engine:
Set the following environmental variables:
GC_BUCKET_NAMEGC_ACCOUNT_FILEGC_PROJECT_IDFor tests that test HyperOne:
Set the following environmental variables:
HYPERONE_TOKENHYPERONE_PROJECTYou have to be authenticated within the h1 tool (use h1 login).
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.
