JarCastingSpark Web Framework Test Library
This library allows testing Spark Web Framework based applications through HTTP. This way, the complete flow of the application can be tested, from the parsing of a HTTP request through business logic, executing asserts against HTTP responses headers, status, body, etc.
Getting Started
Dependency
Maven
Add to your pom.xml dependencies
<dependency>
<groupId>com.despegar</groupId>
<artifactId>spark-test</artifactId>
<version>1.1.8</version>
</dependency>
Gradle
Add to your build.gradle dependencies:
dependencies {
testCompile "com.despegar:spark-test:1.1.8"
}
Usage
/**
* The class that defines a Spark Web Framework route
*
*/
public class TestController {
public TestController() {
get("/test", (request, response) -> this.testMethod(request, response));
}
public String testMethod(Request request, Response response) {
return "This works!";
}
}
/**
* The test class
*
*/
public class TestControllerTest {
public static class TestContollerTestSparkApplication implements SparkApplication {
@Override
public void init() {
new TestController();
}
}
@ClassRule
public static SparkServer<TestContollerTestSparkApplication> testServer = new SparkServer<>(TestControllerTest.TestContollerTestSparkApplication.class, 4567);
@Test
public void test() throws Exception {
/* The second parameter indicates whether redirects must be followed or not */
GetMethod get = testServer.get("/test", false);
get.addHeader("Test-Header", "test");
HttpResponse httpResponse = testServer.execute(get);
assertEquals(200, httpResponse.code());
assertEquals("This works!", new String(httpResponse.body()));
assertNotNull(testServer.getApplication());
}
}
Now http-java-native-client is used. The HTTP response body is a byte[]. You can parse it as necessary.
