# 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](https://github.com/sstephenson/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.
|
|
|
|
## Running Tests
|
|
|
|
### Required Software
|
|
|
|
Before running the tests, you'll need the following installed. If you're
|
|
running on macOS, most of these are available with `brew`:
|
|
|
|
* [Bats](https://github.com/sstephenson/bats)
|
|
|
|
* [AWS cli](http://aws.amazon.com/cli/) for AWS tests as well as most
|
|
of the components.
|
|
|
|
* [gcutil](https://developers.google.com/compute/docs/gcutil/#install) for
|
|
Google Compute Engine tests.
|
|
|
|
* [h1-cli](https://github.com/hyperonecom/h1-client-go) for HyperOne 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_ACCOUNT_FILE`
|
|
* `GC_PROJECT_ID`
|
|
|
|
**For tests that test HyperOne:**
|
|
|
|
Set the following environmental variables:
|
|
|
|
* `HYPERONE_TOKEN`
|
|
* `HYPERONE_PROJECT`
|
|
|
|
You have to be authenticated within the `h1` tool (use `h1 login`).
|
|
|
|
### 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.
