Microservices with Java, Spring Boot and Spring CloudEberhard Wolff
Spring Boot makes creating small Java application easy - and also facilitates operations and deployment. But for Microservices need more: Because Microservices are a distributed systems issues like Service Discovery or Load Balancing must be solved. Spring Cloud adds those capabilities to Spring Boot using e.g. the Netflix stack. This talks covers Spring Boot and Spring Cloud and shows how these technologies can be used to create a complete Microservices environment.

Angular is a TypeScript-based open-source front-end platform that makes it easy to build applications with in web/mobile/desktop. The major features of this framework such as declarative templates, dependency injection, end to end tooling, and many more other features are used to ease the development.
Angular 7 is a Javascript framework built around the concept of components, and more precisely, with the Web Components standard in mind. It was rewritten from scratch by the Angular team using Typescript (although we can use it with ES5, ES6, or Dart as well).
Angular 7 is a big change for us compared to 1.x. Because it is a completely different framework than 1.x, and is not backward-compatible. Angular 7 is written entirely in Typescript and meets the ECMAScript 6 specification

This talk is ideal for researchers and practitioners looking to leverage the power of LLMs in their work, offering a clear guide to harnessing supercomputing resources for quick and effective LLM inference.
Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
Need for Speed: Removing speed bumps from your Symfony projects ⚡️Łukasz Chruściel
No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception.
In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed.
We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.

● @WebMvcTest, etc.
7. Odds and Ends
https://junit.org/junit5/docs/5.7.2/release-notes/
● Numerous APIs promoted from experimental to stable
● Improvements to EngineTestKit
● Improvements to Assertions
● Improvements to @CsvFileSource and @CsvSource
● Custom disabledReason for all @Enabled* / @Disabled* annotations
8. Major Features in 5.7
● Java Flight Recorder support
● junit.jupiter.testmethod.order.default configuration parameter to set the
default MethodOrderer
● used unless @TestMethodOrder is present
● @EnabledIf and @DisabledIf: based on condition methods
● @Isolated: run the test class in isolation during parallel execution
● TypedArgumentConverter for converting one specific type to another
○ use with @ConvertWith in a @ParameterizedTest
○ enhancements and bug fixes in 5.8
10. Major Features in JUnit Platform 1.8
● Declarative test suites via @Suite classes
● SuiteTestEngine in junit-platform-suite-engine module
● new annotations in junit-platform-suite-api module
■ @Suite, @ConfigurationParameter, @SelectUris, @SelectFile, etc.
● UniqueIdTrackingListener
○ TestExecutionListener that tracks the unique IDs of all tests
○ generates a file containing the unique IDs
○ can be used to rerun those tests
■ for example, with GraalVM Native Build Tools
11. Example: Suites before 5.8 – Soon to be Deprecated
// Uses JUnit 4 to run JUnit 5
@RunWith(JUnitPlatform.class)
@SuiteDisplayName("Integration Tests")
@IncludeEngines("junit-jupiter")
@SelectPackages("com.example")
@IncludeTags("integration-test")
public class IntegrationTestSuite {
}
12. Example: Suites with JUnit 5.8
// Uses JUnit 5 to run JUnit 5
@Suite
@SuiteDisplayName("Integration Tests")
@IncludeEngines("junit-jupiter")
@SelectPackages("com.example")
@IncludeTags("integration-test")
public class IntegrationTestSuite {
}
13. Small Enhancements in JUnit 5.8

● Global configuration via junit.jupiter.testclass.order.default configuration
parameter for all test classes
● for example, to optimize the build
● Local configuration via @TestClassOrder for @Nested test classes
17. @TempDir – New Behavior
Due to popular demand from the community…
● @TempDir previously created a single temporary directory per context
● @TempDir can now be used to create multiple temporary directories
● JUnit now creates a separate temporary directory per @TempDir annotation
● Revert to the old behavior by setting the junit.jupiter.tempdir.scope
configuration parameter to per_context
18. @ExtendWith on Fields and Parameters
Improves programming model
● @RegisterExtension: register extensions via fields programmatically
○ nothing new
● @ExtendWith: can now register extensions via fields and parameters declaratively
● fields: static or instance
● parameters: constructor, lifecycle method, test method
● typically as a meta-annotation
● avoids the need to declare @ExtendWith at the class or method level
19. Example: RandomNumberExtension
@Target({ ElementType.FIELD, ElementType.PARAMETER })
@Retention(RetentionPolicy.RUNTIME)
@ExtendWith(RandomNumberExtension.class)
public @interface Random {
}
class RandomNumberExtension implements BeforeAllCallback,
BeforeEachCallback, ParameterResolver {
// implementation...
}
20. Example: @Random in Action
class RandomNumberTests {
@Random
private int randomNumber1;
RandomNumberTests(@Random int randomNumber2) {
}
@BeforeEach
void beforeEach(@Random int randomNumber3) {
}
@Test
void test(@Random int randomNumber4) {
}
}
21. Named API
● Named: container that associates a name with a given payload
○ The meaning of the payload depends on the context
○ Named.of() vs. Named.named()
● DynamicTests.stream() can consume Named input and will use each name-value pair
as the display name and value for each generated dynamic test
● In parameterized tests using @MethodSource or @ArgumentSource, arguments can
now have explicit names supplied via the Named API
○ explicit name used in display name instead of the argument value
22. Example: Named Dynamic Tests
@TestFactory
Stream<DynamicTest> dynamicTests() {
Stream<Named<String>> inputStream = Stream.of(
named("racecar is a palindrome", "racecar"),
named("radar is also a palindrome", "radar"),
named("mom also seems to be a palindrome", "mom"),
named("dad is yet another palindrome", "dad")
);
return DynamicTest.stream(inputStream,
text -> assertTrue(isPalindrome(text)));
}
23. AutoCloseable Arguments in Parameterized Tests
● In parameterized tests, arguments that implement AutoCloseable will now be
automatically closed after the test completes
● Allows for automatic cleanup of resources
○ closing a file
○ stopping a server
○ etc.
● Similar to the CloseableResource support in the ExtensionContext.Store
25. New in Spring Framework 5.3 GA to 5.3.9
https://github.com/spring-projects/spring-framework/releases
● Test configuration is now discovered on enclosing classes for @Nested test classes
● ApplicationEvents abstraction for capturing application events published in the
ApplicationContext during a test
● Set spring.test.constructor.autowire.mode in junit-platform.properties
● Detection for @Autowired violations in JUnit Jupiter
● Improvements for file uploads and multipart support in MockMvc and
MockRestServiceServer
● Various enhancements in MockHttpServletRequest and MockHttpServletResponse
● Improved SQL script parsing regarding delimiters and comments
26. Example: @Nested tests before 5.3
@SpringJUnitConfig(TestConfig.class)
@ActiveProfiles("dev")
@Transactional
class DevTests {
@Nested
@SpringJUnitConfig(TestConfig.class)
@ActiveProfiles("dev")
@Transactional
class OrderTests { /* tests */ }
@Nested
@SpringJUnitConfig(PricingConfig.class)
class PricingTests { /* tests */ }
}
27. Example: @Nested tests after 5.3
@SpringJUnitConfig(TestConfig.class)
@ActiveProfiles("dev")
@Transactional
class DevTests {
@Nested
class OrderTests { /* tests */ }
@Nested
@NestedTestConfiguration(OVERRIDE)
@SpringJUnitConfig(PricingConfig.class)
class PricingTests { /* tests */ }
}
28. Example: ApplicationEvents
@SpringJUnitConfig(/* ... */)
@RecordApplicationEvents
class OrderServiceTests {
@Autowired OrderService orderService;
@Autowired ApplicationEvents events;
@Test
void submitOrder() {
// Invoke method in OrderService that publishes an event
orderService.submitOrder(new Order(/* ... */));
// Verify that 1 OrderSubmitted event was published
assertThat(events.stream(OrderSubmitted.class)).hasSize(1);
}
}
29. Coming in Spring Framework 5.3.10
Improving every step of the way…
● ExceptionCollector testing utility
● Soft assertions for MockMvc and WebTestClient
● Support for HtmlFileInput.setData() with HtmlUnit and MockMvc
● setDefaultCharacterEncoding() in MockHttpServletResponse
● Default character encoding for responses in MockMvc
30. Example: MockMvc without Soft Assertions
mockMvc.perform(get("/person/5").accept(APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(jsonPath("$.name").value("Jane"));
36. GraalVM Native Build Tools
“The Native Build Tools project provides plugins for different build
tools to add support for building and testing native applications
written in Java (or any other language compiled to JVM bytecode)”
● Collaboration between the GraalVM team, the Spring team, and recently the
Micronaut team as well
● Build tools
● Gradle plugin
● Maven plugin
● Compiling native images
● Testing within a native image using the JUnit Platform
37. Why test within a native image?
● Java is “write once; run anywhere”.
● … but a native image is not your app running on the JVM.
● You could just rely on your normal JVM-based test suite.
● … because your app is already tested – right?
● You could test your native app from the outside – for example, via HTTP endpoints.
○ … but do you have HTTP endpoints for every feature of your app?
● Best practice:
○ Write your JVM tests like you normally do.
○ Run the same tests (or a subset) within a native image.
38. How can a Native Build Tools plugin help?
● Runs your tests in the JVM first, using the UniqueIdTrackingListener
○ Tracks the tests you want to run in the native image
○ Necessary since classpath scanning doesn’t work in a native image
● If your tests or the code you’re testing requires reflection, you might need to run your
JVM tests with the GraalVM agent
● Compiles your app and tests into a native image using the JUnitPlatformFeature
(GraalVM Feature)
● Runs your tests within the native image using the NativeImageJUnitLauncher
○ Launches the JUnit Platform and selects your tests based on the output of the
UniqueIdTrackingListener
● Outputs results to the console and XML test reports
39. How to use Native Build Tools
● Follow the instructions for configuring your Gradle or Maven build
○ https://graalvm.github.io/native-build-tools/
● Or use the Spring Native support configured for your automatically
○ https://start.spring.io
● Gradle:
○ gradle nativeTest
○ gradle –Pagent test and gradle –Pagent nativeTest
● Maven:
○ mvn –Dskip -Pnative test
40. Things to keep in mind
● Not everything works in a native image
○ Classpath scanning
○ Dynamic class creation
○ Mockito and various mocking libraries
● You might need to exclude certain tests within a native image
○ For example, via tags or a custom ExecutionCondition in JUnit Jupiter
● Building a native image can take a long time
○ Probably not something you want to do multiple times a day
○ A dedicated CI pipeline might be a better choice
