# Pact Spring/JUnit5 Support
This module extends the base [Pact JUnit5 module](../pact-jvm-provider-junit5). See that for more details.
For writing Spring Pact verification tests with JUnit 5, there is an JUnit 5 Invocation Context Provider that you can use with
the `@TestTemplate` annotation. This will generate a test for each interaction found for the pact files for the provider.
To use it, add the `@Provider` and `@ExtendWith(SpringExtension.class)` and one of the pact source annotations to your test class (as per a JUnit 5 test), then
add a method annotated with `@TestTemplate` and `@ExtendWith(PactVerificationSpringProvider.class)` that
takes a `PactVerificationContext` parameter. You will need to call `verifyInteraction()` on the context parameter in
your test template method.
For example:
```java
@ExtendWith(SpringExtension.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
@Provider("Animal Profile Service")
@PactBroker
public class ContractVerificationTest {
@TestTemplate
@ExtendWith(PactVerificationSpringProvider.class)
void pactVerificationTestTemplate(PactVerificationContext context) {
context.verifyInteraction();
}
}
```
You will now be able to setup all the required properties using the Spring context, e.g. creating an application
YAML file in the test resources:
```yaml
pactbroker:
host: your.broker.host
auth:
username: broker-user
password: broker.password
```
