public final class AssertionSinks extends Object
In this class there are variants that can be used as sinks in the pipeline.
Variants that can be used in-line in a pipeline are in Assertions
.
Modifier and Type | Method and Description |
---|---|
static <T> Sink<T> |
assertAnyOrder(Collection<? extends T> expected)
Asserts that the previous stage emitted the expected items in any order,
but nothing else.
|
static <T> Sink<T> |
assertAnyOrder(String message,
Collection<? extends T> expected)
Asserts that the previous stage emitted the expected items in any order,
but nothing else.
|
static <T> Sink<T> |
assertCollected(ConsumerEx<? super List<T>> assertFn)
Collects all the received items in a list and once the upstream stage is
completed it executes the assertion supplied by
assertFn . |
static <T> Sink<T> |
assertCollectedEventually(int timeoutSeconds,
ConsumerEx<? super List<T>> assertFn)
Collects all the received items into a list and runs the
assertFn
every time a new item is received. |
static <T> Sink<T> |
assertContains(String message,
Collection<? extends T> expected)
Asserts that the previous stage emitted all of the given items in any order.
|
static <T> Sink<T> |
assertOrdered(Collection<? extends T> expected)
Asserts that the previous stage emitted the exact sequence of expected
items and nothing else.
|
static <T> Sink<T> |
assertOrdered(String message,
Collection<? extends T> expected)
Asserts that the previous stage emitted the exact sequence of expected
items and nothing else.

@Nonnull public static <T> Sink<T> assertOrdered(@Nullable String message, @Nonnull Collection<? extends T> expected)
AssertionError
with the given message.
Since Jet jobs are distributed, input from multiple upstream processors is merged in a non-deterministic way. Therefore this assertion is usable only for testing of non-distributed sources.

. If no
items were collected, it will be called with empty list.
Not usable in streaming jobs - use assertCollectedEventually(int, com.hazelcast.function.ConsumerEx<? super java.util.List<T>>)
.
assertFn
- assertion to execute once all items are received@Nonnull public static <T> Sink<T> assertCollectedEventually(int timeoutSeconds, @Nonnull ConsumerEx<? super List<T>> assertFn)
assertFn
every time a new item is received. An AssertionError
thrown from
the assertFn
will be ignored until timeoutSeconds
have
passed, after which the last AssertionError
will be rethrown.
If assertFn
throws any other exception, it will be rethrown
immediately.
When assertFn
completes without any error, the sink will throw
an AssertionCompletedException
to indicate success. Exception is
used to terminate the job so that you can join()
it. This also
requires that there are no other assertions in the job as this one can
complete the job before the other ones succeeded.
The assertion can be validated as follows:
try { jetInstance.newJob(p).join(); Assert.fail("Job should have completed with an AssertionCompletedException, " + "but completed normally"); } catch (CompletionException e) { String errorMsg = e.getCause().getMessage(); Assert.assertTrue( "Job was expected to complete with AssertionCompletedException, but completed with: " + e.getCause(), errorMsg.contains(AssertionCompletedException.class.getName()) ); }
timeoutSeconds
- timeout in seconds, after which any assertion error will be propagatedassertFn
- assertion to execute periodicallyCopyright © 2023 Hazelcast, Inc.. All rights reserved.
