I'm trying to get started with DbFit 4.0.0 as described in Getting Started guide.
I have the following test http://localhost:8085/HelloWorldTest
!path lib/*.jar
!|dbfit.OracleTest|
!|Connect|localhost:1521|integration|integration|XEPDB1|
!|Query| select 'test' as x from dual|
|x|
|test|
But when I run the test I'm getting the following problem:
java.lang.Error: Cannot load Oracle database driver oracle.jdbc.OracleDriver. Is the JDBC driver on the classpath?

I find nothing relevant from:
I'm running DbFit in Linux (Lubuntu 22.04 LTS).
I had to solve the following two problems before I got the example running:
Problem #1 missing Oracle JDBC driver
I downloaded Oracle JDBC driver (ojdbc8.jar) from the Oracle download page:
https://www.oracle.com/database/technologies/appdev/jdbc-downloads.html
and copied it to <DBFIT_HOME>/lib.
Unfortunately after that I run into the second problem.
Problem #2 incorrect connection string
Now I got the following error:
oracle.net.ns.NetException: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor

My connection string:
!|Connect|localhost:1521|integration|integration|XEPDB1|
should be correct and I can connect to the database with other tools.
After a bit of tinkering I got the following connection string working:
!|Connect|jdbc:oracle:thin:integration/integration@localhost:1521/XEPDB1|
In general the connection string format is:
jdbc:oracle:thin:<USER>/<PASSWORD>@<HOST>:<PORT>/<SERVICE_NAME>
See e.g. URL string format for connecting to Oracle database with JDBC
