Following python packages need to be installed before running the tests :

1. blockade
2. pytest==2.8.7
2. pytest==3.2.0

Running test as part of the maven build:

mvn clean verify -Pit

Running test as part of the released binary:

You can execute all blockade tests with following command-lines:

```
cd $DIRECTORY_OF_OZONE
python -m pytest -s tests/blockade/
mvn clean verify -Pit
```

You can also execute fewer blockade tests with following command-lines:

```
cd $DIRECTORY_OF_OZONE
python -m pytest -s tests/blockade/<PATH_TO_PYTHON_FILE>
e.g: python -m pytest -s tests/blockade/test_blockade_datanode_isolation.py
```
Running test as part of the released binary:

You can change the default 'sleep' interval in the tests with following
command-lines:
You can execute all blockade tests with following command:

```
cd $DIRECTORY_OF_OZONE
python -m pytest -s tests/blockade/ --containerStatusSleep=<SECONDS>

e.g: python -m pytest -s tests/blockade/ --containerStatusSleep=720
cd $OZONE_HOME
python -m pytest tests/blockade
```

By default, second phase of the tests will not be run.
In order to run the second phase of the tests, you can run following
command-lines:

```
cd $DIRECTORY_OF_OZONE
python -m pytest -s tests/blockade/ --runSecondPhase=true
You can also execute specific blockade tests with following command:

```
cd $OZONE_HOME
python -m pytest tests/blockade/< PATH TO PYTHON FILE >
e.g: python -m pytest tests/blockade/test_blockade_datanode_isolation.py
