# Testing
NPD is tested via unit tests, [NPD e2e tests](https://github.com/kubernetes/node-problem-detector/blob/master/test/e2e/README.md), Kubernetes e2e tests and Kubernetes nodes e2e tests. Prow handles the [pre-submit tests](https://github.com/kubernetes/test-infra/blob/master/config/jobs/kubernetes/node-problem-detector/node-problem-detector-presubmits.yaml) and [CI tests](https://github.com/kubernetes/test-infra/blob/master/config/jobs/kubernetes/node-problem-detector/node-problem-detector-ci.yaml).
CI test results can be found at below:
1. [Unit tests](https://k8s-testgrid.appspot.com/sig-node-node-problem-detector#ci-npd-test)
2. [NPD e2e tests](https://k8s-testgrid.appspot.com/sig-node-node-problem-detector#ci-npd-e2e-test)
3. [Kubernetes e2e tests](https://k8s-testgrid.appspot.com/sig-node-node-problem-detector#ci-npd-e2e-kubernetes-gce-gci)
4. [Kubernetes nodes e2e tests](https://k8s-testgrid.appspot.com/sig-node-node-problem-detector#ci-npd-e2e-node)
## Running tests
Unit test is ran via `make test`.
See [NPD e2e test documentation](https://github.com/kubernetes/node-problem-detector/blob/master/test/e2e/README.md) for how to setup and run NPD e2e tests.
## Problem Maker
[Problem maker](https://github.com/kubernetes/node-problem-detector/blob/master/test/e2e/problemmaker/README.md) is a program used in NPD e2e tests to generate/simulate node problems. It is ONLY indented to be used by NPD e2e tests. Please do NOT run it on your workstation, as it could cause real node problems.
