* Use terraform to manage ci cluster. Upgrade ci cluster to 1.13
* Upgrade helm version
* Do not break the test if no previous resources
* Do not skip install helm if helm is old version
A few improvements to the integration test:
* Search for test files recursively in the test dir
* Output a test report at the end for a quick summary of what tests passed/failed/were skipped
* Add support skipping test files; skip the logging test since it's broken (#446 is tracking this)
* Switch to latest helm version
* Cleanup namespace
Various e2e test bugfixes. The test runner now compiles fission bundle and cli, installs helm, installs kubectl, and uses helm to install fission, run all scripts under test/tests/, and uninstalls fission.
The change also removes go tip tests -- I think we can get by without them, but we'll add them back if the next go version update brings some surprises.
Travis doesn't pass secret env vars to tests run on forks, so we need
a way to skip the tests when there are no credentials passed in.
This change unsets KUBECONFIG when there's no reachable cluster. The
Go tests already check for KUBECONFIG and skip when it's not defined.
Sets up Travis CI tests to use a Kubernetes cluster on GKE. All tests have access to $KUBECONFIG which points at a kubeconfig file with credentials to a cluster.
I had to skip the poolmgr unit test because it currently assumes NodePort services; that will be fixed in another change.
Also, because some of the tests don't work properly in parallel, I've ended up reducing the concurrency to 1. If this becomes a problem we'll have to fix the tests, but for now I don't mind just waiting a few minutes longer.
