+# Overview
+
+Prometheus for Juju CAAS
+
+## Testing
+
+The tests of this charm are done using tox and Zaza.
+
+
+
+### Prepare environment
+
+The machine in which the tests are run needs access to a juju k8s controller. The easiest way to approach this is by executing the following commands:
+
+```
+sudo apt install tox -y
+sudo snap install microk8s --classic
+sudo snap install juju
+
+microk8s.status --wait-ready
+microk8s.enable storage dashboard dns
+
+juju bootstrap microk8s k8s-cloud
+```
+
+If /usr/bin/python does not exist, you should probably need to do this:
+
+```
+sudo ln -s /usr/bin/python3 /usr/bin/python
+```
+### Build Charm
+
+**Download dependencies:**
+
+```
+mkdir -p ~/charm/layers ~/charm/build ~/charm/interfaces
+git clone https://git.launchpad.net/canonical-osm ~/canonical-osm
+
+cd ~/charm/layers
+git clone https://git.launchpad.net/charm-k8s-prometheus prometheus-k8s 
+
+cd ~/charm/interfaces
+mv ~/canonical-osm/charms/interfaces/* .
+```
+
+**Charm structure:**
+
+```
+├── config.yaml
+├── icon.svg
+├── layer.yaml
+├── metadata.yaml
+├── reactive
+│   ├── spec_template.yaml
+│   └── prometheus.py
+├── README.md
+├── test-requirements.txt
+├── tests
+│   ├── basic_deployment.py
+│   ├── bundles
+│   │   ├── prometheus-ha.yaml
+│   │   └── prometheus.yaml
+│   └── tests.yaml
+└── tox.ini
+```
+
+**Setup environment variables:**
+
+```
+export CHARM_LAYERS_DIR=~/charm/layers
+export CHARM_BUILD_DIR=~/charm/build
+export CHARM_INTERFACES_DIR=~/charm/interfaces
+```
+
+**Build:**
+
+```
+mkdir ~/charm/layers/prometheus-k8s/tests/build
+charm build ~/charm/layers/prometheus-k8s
+mv ~/charm/build/* ~/charm/layers/prometheus-k8s/tests/build/
+```
+
+### Test charm with Tox
+
+```
+cd ~/charm/layers/prometheus-k8s
+tox -e func
+```
