 This code implies that it is run in the environment with `pyignite` package
 installed, and Apache Ignite node is running on localhost:10800.
 
 ## Testing
-*NB!* All tests require Apache Ignite node running on localhost:10800. For the convenience, `docker-compose.yml` is present.
-So installing `docker` and `docker-compose` is recommended. Also, it is recommended installing `pyignite` in development
-mode. You can do that using following command:
-```
-$ pip install -e .
-```
-### Run without ssl
+*NB!* It is recommended installing `pyignite` in development mode.
+Refer to [this section](#for-developer) for instructions.
+
+Also, you'll need to have a binary release of Ignite with lib4j2 enabled and
+`IGNITE_HOME` properly set: 
+```bash
+$ cd <ignite_binary_release>
+$ export IGNITE_HOME=$(pwd)
+$ cp -r libs/optional/ignite-log4j2/* libs/
 ```
-$ docker-compose down && docker-compose up -d ignite
-$ pytest
+### Run basic tests
+```bash
+$ python ./setup.py pytest
 ```
 ### Run with examples
-```
-$ docker-compose down && docker-compose up -d ignite
-$ pytest --examples
+```bash
+$ python ./setup.py pytest --addopts="--examples" 
 ```
 ### Run with ssl and not encrypted key
-```
-$ docker-compose down && docker-compose up -d ignite
-$ pytest --use-ssl=True --ssl-certfile=./tests/config/ssl/client_full.pem
+```bash
+$ python ./setup.py pytest --addopts="--use-ssl=True --ssl-certfile=./tests/ssl/client_full.pem" 
 ```
 ### Run with ssl and password-protected key
-```
-$ docker-compose down && docker-compose up -d ignite
-$ pytest --use-ssl=True --ssl-certfile=./tests/config/ssl/client_with_pass_full.pem --ssl-keyfile-password=654321
+```bash
