# LogsSpy
LogsSpy is a JUnit5 extension used to assert logs.
## Usage
Sometimes it's a good idea to test logs (as they can be important information for our system). It's not always needed though, as for everything, it depends!
So, here's how to use it:
```java
@UnitTest
@ExtendWith(LogsSpyExtension.class)
class MyTest {
@Logs
private LogsSpy logs;
@Test
void shouldDoStuff() {
doingStuff();
logs.shouldHave(Level.INFO, "some stuff");
logs.shouldHave(Level.DEBUG, "repeated stuff", 5);
logs.shouldNotHave(Level.ERROR, "this is an error");
}
}
```
