@ScannerSide @ServerSide @ComputeEngineSide public class System2 extends Object
System. It aims to improve testability of classes
that interact with low-level system methods, for example :
public class MyClass {
private final System2 system;
public MyClass(System2 s) {
this.system = s;
}
public long xxx() {
return system.now();
}
}
@Test
public void should_return_xxx() {
// using Mockito
System2 system = mock(System2.class);
long now = 123456789L;
doReturn(now).when(system).now();
assertThat(new MyClass(system).xxx()).isEqualTo(now);
}
System.
