Review Comment:
This method is only used by `MongoDb4ProviderTest` to get the collection
name from a `MongoDb4Provider`. You can use `MongoDb4Provider::getConnection`
to obtain the `MongoDb4Connection` instance, and use reflection on that
instance to get the value of its `collection` field:
```java
private static MongoNamespace findProviderNamespace(final MongoDb4Provider
provider) {
MongoDb4Connection connection = provider.getConnection();
try {
Field collectionField =
connection.getClass().getDeclaredField("collection");
collectionField.setAccessible(true);
MongoCollection<?> collection = (MongoCollection<?>)
collectionField.get(connection);
return collection.getNamespace();
} catch (Exception exception) {
throw new RuntimeException(exception);
}
}
```
Then you can replace
```java
assertEquals(
collectionName,
provider.getConnection().getCollection().getNamespace().getCollectionName());
```
with
```java
MongoNamespace namespace = findProviderNamespace(provider);
assertThat(namespace.getCollectionName()).isEqualTo(collectionName);
```
