  How to run tests
---

### Unit Tests

Unit tests are run on Travis before code is merged. To run as part of a development cycle:

```shell
make test
```

### Integration Tests

Integration tests are currently run manually.
To run them, build the binary and run the tests:

```shell
make integration
```

You may find it useful to set various options to test only a particular test against a non-default driver. For instance:

```shell
 env TEST_ARGS="-minikube-start-args=--driver=hyperkit -test.run TestStartStop" make integration
 ```

### Conformance Tests

These are Kubernetes tests that run against an arbitrary cluster and exercise a wide range of Kubernetes features.
You can run these against minikube by following these steps:

* Clone the Kubernetes repo somewhere on your system.
* Run `make quick-release` in the k8s repo.
* Start up a minikube cluster with: `minikube start`.
* Set following two environment variables:

```shell
export KUBECONFIG=$HOME/.kube/config
export KUBERNETES_CONFORMANCE_TEST=y
```

* Run the tests (from the k8s repo):

```shell
go run hack/e2e.go -v --test --test_args="--ginkgo.focus=\[Conformance\]" --check-version-skew=false
```

To run a specific conformance test, you can use the `ginkgo.focus` flag to filter the set using a regular expression.
The `hack/e2e.go` wrapper and the `e2e.sh` wrappers have a little trouble with quoting spaces though, so use the `\s` regular expression character instead.
For example, to run the test `should update annotations on modification [Conformance]`, use following command:

```shell
go run hack/e2e.go -v --test --test_args="--ginkgo.focus=should\supdate\sannotations\son\smodification" --check-version-skew=false
```
