Pact Contract Testing

Pact is a consumer-driven contract testing tool that ensures different services can communicate correctly.

Why Contract Testing?​

Traditional E2E tests are often slow and flaky. Contract testing allows you to:

  • Fast Feedback: Catch breaking API changes at build time.
  • Reduce Flakiness: Replace unstable E2E tests with fast, deterministic contract tests.

🛠 Configuration​

Enable Pact in your automation.properties file:

# Enable Pact
pact.enabled=true

🧑‍💻 Consumer Testing​

The PactManager helps manage the lifecycle of contract tests.

Usage in Tests​

public class MyContractTest {
    private PactManager pactManager = new PactManager();

    @BeforeClass
    public void setup() {
        pactManager.setup("my-consumer", "my-provider");
    }

    @Test
    public void testContract() {
        if (pactManager.isEnabled()) {
            // Use Pact DSL to define expectations
        }
    }
}

Dependencies​

Pact dependencies are included in build.gradle under the implementation scope to ensure they are available for both the framework core and your tests.
