Review comment:
Try to avoid nesting especially when it's unnecessary.
```
if (!recoverQueuesOnly && queue.localSize() > 0) {
queue.notifyEventProcessorIfRequired();
}
```
Or you could extract that conditional to a small private method with a
descriptive name to make it easier to understand. It's hard to figure out what
`!recoverQueuesOnly && queue.localSize() > 0` really means unless I study the
rest of the code in this class.

You should probably just the `name()` which is built-in to Java enums:
```

Review comment:
Here's the way you do this with AssertJ:
```
import static org.assertj.core.api.Assertions.catchThrowable;
```
```
Throwable thrown = catchThrowable(() ->
parser.startElement("http://geode.apache.org/schema/cache";,
"gateway-sender", "gateway-sender", attrs));
assertThat(thrown)
.isInstanceOf(InternalGemFireException.class)
.hasMessage("An invalid startup-action value (pausede) was configured for
gateway sender sender1");
```

Review comment:
Please avoid abbreviations as much as possible and just spell out
`attributes`.
Also, if the APIs that use `attrs` support the interface `Attributes` then
please always declare everything as the interfaces instead of the impl.

Review comment:
Please try to think of some ways to test dropped events without having
to resort to a test hook. Test hooks in the product code should always be the
very last resort. It would be better to refactor the class, wrap it with a
decorator, introduce a factory that can wrap all instances with an optional
decorator, etc.
In general, I recommend very detailed white-box testing at the unit test
level. The system test level (includes dunit/distributed tests) should be lean
more towards higher level black-block testing.

Review comment:
The conditionals of this else-if block are kind of convoluted. I
recommend extracting it to a single method with a name that describes it well
and returns a single boolean so that you can rewrite it as:
```
} else if (isManualStartupRequired()) {
senderImpl.recoverInStoppedState();
}
```
I'm not sure if `isManualStartupRequired()` is a good name... I'm just
guessing here.

Review comment:
Please don't catch Exceptions in tests unless you need to assert its
type or message. You just need to make sure the test method has `throws
InterruptedException` (which it does) and then delete the try-catch blocks.
Please make sure that you define the `AsyncInvocation` types as
`AsyncInvocation<Void>` unless they have a return value. Use descriptive names
for these variables and use `await()` instead of `join()`. The javadocs on
`AsyncInvocation` have some good guidelines.
```
AsyncInvocation<Void> createRegionInVm4 = vm4.invokeAsync(() -> WANTestBase
.createPersistentPartitionedRegion(getTestMethodName(), "ln", 1,
100, isOffHeap()));
createRegionInVm4.await();
```
However, in this case you should NOT use `invokeAsync` and
`AsyncInvocations` unless this test has a very specific need to create the
regions asynchronously. It's more common to use this API for spawning remote
threads that are doing region operations asynchronously. So it's probably
better to just synchronously create these regions:
```
import static
org.apache.geode.internal.cache.wan.WANTestBase.createPersistentPartitionedRegion;
vm4.invoke(() -> createPersistentPartitionedRegion(getTestMethodName(),
"ln", 1, 100, isOffHeap()));
vm5.invoke(() -> createPersistentPartitionedRegion(getTestMethodName(),
"ln", 1, 100, isOffHeap()));
```
