CloudPosse Terraform Testing

(Tested in zsh shell)

Mac

1. Set env vars:
2. export GITHUB_TOKEN=...
3. export GOEXE=/usr/local/bin/go
4. Change test/src/Makefile:

ifeq ($(shell uname -s),Linux)
# becomes:
ifeq ($(shell uname -s),$(filter $(shell uname -s),Linux Darwin))

3. Create an AWS session (i.e. AWS_SECRET_ACCESS_KEY, AWS_ACCESS_KEY_ID, AWS_SESSION_TOKEN set)

aws-vault exec my-profile

4. cd test/src
5. make test

Docker

Ensure you don't have the above Makefile changes for Mac

With cloudposse/test-harness

1. Create an AWS session (i.e. AWS_SECRET_ACCESS_KEY, AWS_ACCESS_KEY_ID, AWS_SESSION_TOKEN set)

aws-vault exec my-profile

2. cd test/src
3. docker run --rm -it -e AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY -e AWS_SESSION_TOKEN -e GITHUB_TOKEN -e PATH="/usr/local/terraform/0.12/bin:/go/bin:/usr/local/go/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" -v $(pwd)/../../:/module/ cloudposse/test-harness -C /module/test/src test

With Geodesic

1. Create an AWS session (i.e. AWS_SECRET_ACCESS_KEY, AWS_ACCESS_KEY_ID, AWS_SESSION_TOKEN set)

aws-vault exec my-profile

2. cd test/src
3. docker run --rm -it -e GOEXE=/usr/local/go/bin/go -e AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY -e AWS_SESSION_TOKEN -e GITHUB_TOKEN -v $(pwd)/../../:/module/ cloudposse/geodesic:0.132.2 make -C /module/test/src test

We can now also use cloudposse/test-harness:latest
