every test is separate executable file
backend for test:
- 1 machine for Maxscale
- = 4 machines for Master/Slave
- = 4 machines for Galera cluster
environmental variables contains all information about backend: IPs, user names, passwords, paths to tools, etc
backed can be created with help of MDBCI tool
configuring of Master/Slave and Galera can be done with help of build scripts package
