Note:There is a new version for this artifact:
3.5.24
pact-jvm-consumer-junit_2.11
pact-jvm-consumer-junit
=======================
Provides a DSL and a base test class for use with Junit to build consumer tests.
## Dependency
The library is available on maven central using:
* group-id = `au.com.dius`
* artifact-id = `pact-jvm-consumer-junit_2.11`
* version-id = `3.2.x`
## Usage
### Using the base ConsumerPactTest
To write a pact spec extend ConsumerPactTestMk2. This base class defines the following four methods which must be
overridden in your test class.
* *providerName:* Returns the name of the API provider that Pact will mock
* *consumerName:* Returns the name of the API consumer that we are testing.
* *createFragment:* Returns the PactFragment containing the interactions that the test setup using the
ConsumerPactBuilder DSL
* *runTest:* The actual test run. It receives the URL to the mock server as a parameter.
Here is an example:
```java
import au.com.dius.pact.consumer.dsl.PactDslWithProvider;
import au.com.dius.pact.consumer.exampleclients.ConsumerClient;
import au.com.dius.pact.consumer.ConsumerPactTest;
import au.com.dius.pact.model.PactFragment;
import org.junit.Assert;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
import static org.junit.Assert.assertEquals;
public class ExampleJavaConsumerPactTest extends ConsumerPactTestMk2 {
@Override
protected RequestResponsePact createFragment(PactDslWithProvider builder) {
Map<String, String> headers = new HashMap<String, String>();
headers.put("testreqheader", "testreqheadervalue");
return builder
.given("test state") // NOTE: Using provider states are optional, you can leave it out
.uponReceiving("ExampleJavaConsumerPactTest test interaction")
.path("/")
.method("GET")
.headers(headers)
.willRespondWith()
.status(200)
.headers(headers)
.body("{\"responsetest\": true, \"name\": \"harry\"}")
.given("test state 2") // NOTE: Using provider states are optional, you can leave it out
.uponReceiving("ExampleJavaConsumerPactTest second test interaction")
.method("OPTIONS")
.headers(headers)
.path("/second")
.body("")
.willRespondWith()
.status(200)
.headers(headers)
.body("")
.toPact();
}
@Override
protected String providerName() {
return "test_provider";
}
@Override
protected String consumerName() {
return "test_consumer";
}
@Override
protected void runTest(MockServer mockServer) throws IOException {
Assert.assertEquals(new ConsumerClient(mockServer.getUrl()).options("/second"), 200);
Map expectedResponse = new HashMap();
expectedResponse.put("responsetest", true);
expectedResponse.put("name", "harry");
assertEquals(new ConsumerClient(mockServer.getUrl()).getAsMap("/", ""), expectedResponse);
assertEquals(new ConsumerClient(mockServer.getUrl()).options("/second"), 200);
}
}
```
### Using the Pact JUnit Rule
Thanks to [@warmuuh](https://github.com/warmuuh) we have a JUnit rule that simplifies running Pact consumer tests. To use it, create a test class
and then add the rule:
#### 1. Add the Pact Rule to your test class to represent your provider.
```java
@Rule
public PactProviderRuleMk2 mockProvider = new PactProviderRuleMk2("test_provider", "localhost", 8080, this);
```
The hostname and port are optional. If left out, it will default to 127.0.0.1 and a random available port. You can get
the URL and port f
