Review comment:
It's better (and more industry standard for writing JUnit tests) if you
can figure out a way to move cleanup code from the end of the test method to a
`tearDown` method annotated with `@After`. For example, if you make
`cqHelper.closeClient` return without error if client is null or not running,
then you could hoist these local variables to fields and the test would look
more like this:
```
private VM client;
private VM server1;
private VM server2;
@Before
public void setUp() {
server1 = getVM(0);
server2 = getVM(1);
client = getVM(2);
}
@After
public void tearDown() {
cqHelper.closeClient(client);
cqHelper.closeServer(server2);
cqHelper.closeServer(server1);
}
```
And `cqHelper` close methods could have some early-outs like this:
```
public void closeClient(VM vm) {
if (vm == null) {
return;
}
// etc
}
```
