I have a Gradle project with a Quarkus application to deploy a RESTful API.
The Gradle project is broken into 2 sub-projects: 'app' and 'spec'. spec is using the Open API Generator to create the RestEasy Classic (RestEasy Reactive doesn't appear to be available at this taime) interfaces and classes. app has a dependency on that sub-project.
The 'app' project has several directories/modules:
Unfortunately, only the unit tests (which are basic JUnit 5 tests) will run successfully (pass/fail). I receive the following stack trace when attempting to execute the @QuarkusTest annotated tests:
java.lang.ClassCastException: class io.quarkus.builder.BuildChainBuilder cannot be cast to class io.quarkus.builder.BuildChainBuilder (io.quarkus.builder.BuildChainBuilder is in unnamed module of loader io.quarkus.bootstrap.classloading.QuarkusClassLoader @45cff11c; io.quarkus.builder.BuildChainBuilder is in unnamed module of loader 'app')

I thought the Gradle plugin Unbroken Dome TestSets might have been conflicting with the Quarkus platform generated modules integrationTest and test. After replacing that plugin with basic configuration changes to achieve the same purpose, it still fails at the same point.
Moving the test to a Quarkus test module has no change either.
Not all modules will rely on the Quarkus Testing libraries as I'm aware of challenges mixing them. For example, the smoke test will only rely on RestAssured to execute liveness/health checks after deploy. Integration testing could be done with Docker instead of the Qaurkus library.
I would like to use component level testing on the CDI generated beans from Quarkus if I can, for example:
@RequestScoped
public class SomeService {
@Inject
DatabaseService databaseService;
}
In test:
@QuarkusTest
public class ComponentTest {
@Inject
SomeService someService;
@Test
void test() {
//Run tests on someService with injected dependencies
}
}
So it all comes down to how to successfully get the component test to run. Any help is appreciated.
To achieve the desired outcome of splitting Quarkus-specific tests from other types, the following Gradle changes will be required:
sourceSets {
smokeTest {
compileClasspath += main.output
runtimeClasspath += main.output
java {
srcDir file('src/smokeTest/java')
}
resources.srcDir file('src/smokeTest/resources')
}
}
configurations {
smokeTestImplementation.extendsFrom(testImplementation)
smokeTestRuntimeOnly.extendsFrom(testRuntimeOnly)
}
task smokeTest(type: Test) {
description = "Run smoke tests"
group = "verification"
testClassesDirs = sourceSets.smokeTest.output.classesDirs
classpath = sourceSets.smokeTest.runtimeClasspath
}
test scope.dependencies {
testImplementation "org.junit.jupiter:${jupiterVersion}"
// This is used for unit tests under 'test' directory.
testImplementation "io.rest-assured:rest-assured:${restAssuredVersion}"
// This is in same scope as unit tests but are smoke test dependencies
}
Write your new tests.
├── main
├── test
│ ├── java
│ └── resources
├── smokeTest
│ ├── java
│ └── resources
Any resources required by the new directory will also be in the test/resources directory. This is likely a small issue with my configuration and could be corrected to pull from the appropriate directory, but it also helps when tests need to share the same resources, e.g. import.sql.
Addressing the original Class Cast Exception issue; I am guessing but think that the method Quarkus uses for swapping out core components for test vs dev vs prod is the source. As I roughly understand it, Quarkus would use a different ClassLoader, for example, so when the Quarkus Test Extension tries to load BuildChainBuilder its using a production version and not the non-prod type.
