Add CI against multiple C* versions (#59)
Add multi-version testing infrastructure
Testing Infrastructure:
- Add Testcontainers-based testing for Cassandra 4.0, 4.1, 5.0
- Add workload filtering with @MinimumVersion annotation
Gradle Tasks:
- Create version-specific test tasks: test40, test41, test50, testtrunk
- Add testAllVersions task to run all versions sequentially
CI Improvements:
- Run tests across 7 matrix combinations (Java 17+21 × versions)
- Separate lint, detekt, and kover as independent jobs
Documentation:
- Add comprehensive testing documentation to README
- Explain Testcontainers usage, annotations, and CI workflows
- Provide troubleshooting guide and best practices
Build Artifacts:
- Add build job to CI that runs after all tests pass
- Publish shadowJar as GitHub Actions artifact (90-day retention)
- Build job only runs on main branch
- publish docker container with latest main to GHCR
Tests:
- Marked flakey test as disabled
Testing now covers stable versions: Cassandra 4.0, 4.1, and 5.0
Latest build artifacts available via GitHub Actions UI after successful CI
runs

+## A workload centric stress tool and framework designed for ease of use.
-cassandra-easy-stress is a configuration-based tool for doing benchmarks and
testing simple data models for Apache Cassandra.
-Unfortunately, it can be challenging to configure a workload. There are fairly
common data models and workloads seen on Apache Cassandra.
-This tool aims to provide a means of executing configurable, pre-defined
profiles.
+[](https://github.com/apache/cassandra-easy-stress/actions/workflows/ci.yml)
+
+cassandra-easy-stress is a powerful and flexible tool for performing
benchmarks and testing data models for Apache Cassandra.
+
+Most benchmarking tools require learning complex configuration systems before
you can run your first test. cassandra-easy-stress provides pre-built workloads
for common Cassandra patterns. Modify these workloads with flexible parameters
to match your environment, or write custom workloads in Kotlin when you need
full control.

# Testing
-## Running Tests
+## Quick Start
+
+Run all tests against the default version (Cassandra 5.0):
+
+```bash
+./gradlew test
+```
+
+Run tests against a specific version:
+
+```bash
+./gradlew test40 # Cassandra 4.0
+./gradlew test41 # Cassandra 4.1
+./gradlew test50 # Cassandra 5.0
+```
+
+Run tests against all versions sequentially:
+
+```bash
+./gradlew testAllVersions
+```
+
+## Test Infrastructure
+
+### Testcontainers
+
+All integration tests use [Testcontainers](https://www.testcontainers.org/) to
automatically manage Cassandra instances. This means:
+
+- **No manual setup required**: Docker is the only prerequisite
+- **Isolated test environments**: Each test class gets a fresh Cassandra
container
+- **Automatic cleanup**: Containers are stopped and removed after tests
complete
+- **Version flexibility**: Different Cassandra versions can be tested without
installing anything
+
+When a test class extends `CassandraTestBase`, the framework automatically:
+
+1. Detects the `CASSANDRA_VERSION` environment variable (defaults to "5.0")
+2. Builds a Docker image from the corresponding Dockerfile in
`docker/cassandra-{version}/`
+3. Starts a Cassandra container and waits for it to be ready
+4. Establishes a CQL session with appropriate timeouts for testing
+5. Cleans up and stops the container when tests finish
+
+### Custom Docker Images
+
+Each Cassandra version uses a custom Dockerfile that enables experimental
features:
+
+- **Materialized Views**: Enabled via `materialized_views_enabled: true`
+- **Increased Timeouts**: Higher read/write/range timeouts for test stability
+- **Memory Configuration**: Conservative heap settings suitable for containers
+
+The Dockerfiles are located at:
+- `docker/cassandra-4.0/Dockerfile`
+- `docker/cassandra-4.1/Dockerfile`
+- `docker/cassandra-5.0/Dockerfile`
+
+## Workload Filtering Annotations
+
+Some workloads require specific Cassandra versions or features. Annotations
control when workloads are tested.
+
+### @MinimumVersion
+
+Marks workloads that require a minimum Cassandra version. Tests automatically
skip these workloads on older versions.
+
+**Example:**
+```kotlin
+@MinimumVersion("5.0")
+class SAI : IStressWorkload {
+ // SAI indexes are only available in Cassandra 5.0+
+}
+```
+
+**How it works:**
+- The `CASSANDRA_VERSION` environment variable determines which version is
running
+- `Workload.getWorkloadsForTesting()` filters out workloads where the version
doesn't meet the minimum
+- Version comparison supports point releases: "5.0", "5.1", etc.
+
+**Currently annotated workloads:**
+- `MaterializedViews` - Requires 5.0+ (materialized views enabled)
+- `SAI` - Requires 5.0+ (Storage Attached Indexes)
+
+### @RequireDSE
+
+Marks workloads that require DataStax Enterprise features. These are skipped
by default.
-To run the test suite:
+**Example:**
+```kotlin
+@RequireDSE
+class DSESearch : IStressWorkload {
+ // Uses DSE Search (Solr) functionality
+}
+```
- ./gradlew test
+**Enable in tests:**
+```bash
+TEST_DSE=1 ./gradlew test
+```
-## Special Workloads
+**Currently annotated workloads:**
+- `DSESearch` - Uses DSE Search (Solr)
-Some workloads require specific features or configurations that may not be
available in all Cassandra deployments. These workloads are marked with special
annotations and are skipped by default when running tests.
+### @RequireAccord
-### DSE-Specific Workloads
+Marks workloads that use Accord transaction features (available in Cassandra
6.0+). These are skipped by default.
-Workloads that require DataStax Enterprise (DSE) features are marked with the
`@RequireDSE` annotation.
+**Example:**
+```kotlin
+@RequireAccord
+class TxnCounter : IStressWorkload {
+ // Uses Accord transactions
+}
+```
-Currently, the following workloads require DSE:
-- `DSESearch` - Uses DSE Search (Solr) functionality
+**Enable in tests:**
+```bash
+TEST_ACCORD=1 ./gradlew test
+```
-To run tests that require DSE, set the `TEST_DSE` environment variable:
+**Currently annotated workloads:**
+- `TxnCounter` - Uses Accord transactions
- TEST_DSE=1 ./gradlew test
+### Running All Special Workloads
-### Materialized Views Workloads
+To run all tests including DSE and Accord workloads:
-Workloads that use Materialized Views are marked with the `@RequireMVs`
annotation. Materialized Views are not enabled by default.
+```bash
+TEST_DSE=1 TEST_ACCORD=1 ./gradlew test
+```
-Currently, the following workloads require Materialized Views:
-- `MaterializedViews` - Tests materialized view functionality
+## Gradle Test Tasks
-To run tests that require Materialized Views, set the `TEST_MVS` environment
variable:
+### Version-Specific Tasks
- TEST_MVS=1 ./gradlew test
+Individual test tasks are created for each Cassandra version:
-### Accord Workloads
+```bash
+./gradlew test40 # Cassandra 4.0
+./gradlew test41 # Cassandra 4.1
+./gradlew test50 # Cassandra 5.0
+```
-Workloads that use Accord (available in Cassandra 6.0+) are marked with the
`@RequireAccord` annotation.
+These are proper Gradle `Test` tasks, so they support all standard Test task
options:
-Currently, the following workloads require Accord:
-- `TxnCounter` - Tests Accord transaction functionality
+```bash
+# Run only specific tests
+./gradlew test50 --tests "*KeyValue*"
-To run tests that require Accord, set the `TEST_ACCORD` environment variable:
+# Enable debug mode
+./gradlew test50 --debug-jvm
- TEST_ACCORD=1 ./gradlew test
+# Rerun even if up-to-date
+./gradlew test40 --rerun-tasks
+```
-### Running All Tests
+**How they work:**
+- Each task sets `CASSANDRA_VERSION` environment variable to the corresponding
version
+- Uses the same test sources and classpath as the main `test` task
+- Integrates with Gradle's task graph for proper caching and dependency
management
-To run all tests including DSE, Materialized Views, and Accord workloads:
+### testAllVersions Task
- TEST_DSE=1 TEST_MVS=1 TEST_ACCORD=1 ./gradlew test
+Runs tests against all Cassandra versions sequentially:
-Make sure you have the appropriate Cassandra configuration and features
enabled before running these specialized tests.
+```bash
+./gradlew testAllVersions
+```
+
+This task:
+- Depends on `test40`, `test41`, and `test50`
+- Enforces sequential execution using `mustRunAfter` to prevent Docker
resource conflicts
+- Stops on the first failure and reports which version failed
+- Displays a summary of all test results
+
+**Execution time:**
+- With cached Docker images: ~15-25 minutes total
+
+### Standard test Task
+
+The standard `test` task respects the `CASSANDRA_VERSION` environment variable:
+
+```bash
+# Test against Cassandra 4.1
+CASSANDRA_VERSION=4.1 ./gradlew test
+
+# Test against Cassandra 5.0 (default)
+CASSANDRA_VERSION=5.0 ./gradlew test
+```
+
+If `CASSANDRA_VERSION` is not set, it defaults to "5.0".
+
+## Continuous Integration
+
+### CI Workflow Structure
+
+The GitHub Actions CI workflow (`.github/workflows/ci.yml`) runs on every push
and pull request.
+
+**Test matrix:**
+- **Java versions**: 17 and 21
+- **Cassandra versions**: 4.0, 4.1, 5.0
+
+This creates 6 test jobs total:
+- Cassandra 4.0 on Java 17 and 21
+- Cassandra 4.1 on Java 17 and 21
+- Cassandra 5.0 on Java 17 and 21
+
+**Workflow steps:**
+
+1. **Checkout and setup**: Check out code, set up JDK and Gradle
+2. **Run tests**: Execute the version-specific test task (e.g., `./gradlew
test50`)
+3. **Code quality**: Run ktlint and detekt checks in parallel
+4. **Coverage**: Generate code coverage reports with kover (using default test
task only)
+5. **Build**: Create distribution tarball artifact (main branch only, after
all checks pass)
+ - Artifact: `cassandra-easy-stress-{version}.tar.gz`
+ - Retention: 90 days
+ - Contains: binaries, all dependencies, and LICENSE
+
+### Running CI Tests Locally
+
+Replicate CI behavior locally:
+
+```bash
+# Run the same tests as CI for Cassandra 5.0
+./gradlew test50 ktlintCheck detekt
+
+# Test all versions like CI does (sequentially)
+./gradlew testAllVersions
+
+# Generate coverage report
+./gradlew test koverXmlReport
+```
+
+## Writing Tests
+
+Integration tests extend `CassandraTestBase`:
+
+```kotlin
+class MyWorkloadTest : CassandraTestBase() {
+ @Test
+ fun testWorkload() {
+ // connection is available from CassandraTestBase
+ val result = connection.execute("SELECT * FROM system.local")
+ assertThat(result).isNotNull
+ }
+}
+```
+
+**Available properties from CassandraTestBase:**
+- `connection`: CqlSession instance
+- `ip`: Container IP address
+- `port`: Mapped CQL port
+- `localDc`: Datacenter name (defaults to "datacenter1")
+
+**Utility methods:**
+- `cleanupKeyspace()`: Drops the test keyspace
+- `keyspaceExists()`: Checks if test keyspace exists
+- `getCassandraVersion()`: Returns Cassandra release version string
+
+**Test guidelines:**
+- Use `CassandraTestBase` for integration tests requiring Cassandra
+- Use `@BeforeEach` to ensure clean state with `cleanupKeyspace()`
+- Use AssertJ assertions for clear, fluent test assertions
+- Test against multiple versions if workload behavior varies by version
+- Don't use `runBlocking` in tests (use `kotlinx.coroutines.test.runTest`
instead)
