JarCastingA Collection of rx related libraries
rxjava-test-dsl
Overview
Rx is great, but testing your awesome sequences can be pain
rx-test aims to provide a simple, extensible DSL to enable easier, more declarative rx testing
A taster (see the tests for more examples)
DualSourceScenario<String, Integer, String> testScenario = TestScenario.dualSources();
testScenario
.given()
.theStreamUnderTest((s1, s2) -> s1.zipWith(s2, (z, n) -> z + n))
.renderer(s -> s)
.when()
.theSubscriber().subscribes()
.source1().emits("a")
.source2().emits(1)
.source1().emits("b")
.source2().emits(2)
.source1().completes()
.then()
.theSubscribers()
.eventCount().isEqualTo(2)
.renderedStream().isEqualTo("[a1]-[b2]-|");
SingleSourceScenario<String, List<String>> testScenario = TestScenario.singleSource();
testScenario
.given()
.theStreamUnderTest((source, scheduler) -> source.buffer(10, TimeUnit.SECONDS, scheduler))
.when()
.subscriber("s1").subscribes()
.theSource().emits("1a")
.theSource().emits("1b")
.theSource().emits("1c")
.time().advancesBy(Duration.ofSeconds(11))
.theSource().emits("2a")
.theSource().emits("2b")
.theSource().completes()
.then()
.subscriber("s1")
.eventCount().isEqualTo(2)
.event(0).isEqualTo(asList("1a", "1b", "1c"))
.event(1).isEqualTo(asList("2a", "2b"));
rxjava-test-kafka
Overview
An extension to rx-test that allows for the incorporation of kafka publisher/ consumers within the tests
A taster (see the tests for more examples)
String group = UUID.randomUUID().toString();
new KafkaSourceScenario<String, String, String>()
.given()
.aNewTopic() // Create a randomly named topic on the fly
.asyncTimeoutOf(Duration.ofSeconds(10))
.theStreamUnderTest(topic -> KafkaStream.newBuilder(topic.getName(), group).newMergedStream().map(e -> e.getValue()))
.when()
.theSubscriber().subscribes()
.thePublisher().publishes("1", "1")
.thePublisher().publishes("2", "2")
.theSubscriber().waitsForEvents(2)
.then()
.theSubscribers().renderedStream().isEqualTo("[1]-[2]");
