1 |
Put into this folder the resources needed by your test classes. |
|
2 |
|
|
3 |
This folder is added to the Tests classpath, so you can load any resources |
|
4 |
through the ClassLoader. |
|
5 |
|
|
6 |
By default, in this folder you can find an example of log4j configuration, |
|
7 |
prepared to log messages through the console, so logging works when you |
|
8 |
run your tests classes. |
