Load test example with The Grinder with java, dependency injection with PicoContainer
- Single script to bridge between java and jython
- Pico container to inject dependencies to Test Runner.
-
Create a test runner by extending AbstractTestRunner.java:
public class HttpGetTestRunner extends AbstractTestRunner { .... } -
Inject test dependencies with @Resource annotation :
public class HttpGetTestRunner extends AbstractTestRunner { .... @Resource private UrlProvider urlProvider; .... } -
Based on the test need, a new implementation of the following providers/interfaces may be required:
- UrlProvider - provides URL(s) to be tested.
- DataProvider - provides json data to be tested(for put/post etc.).
- HeaderProvider - provides http headers required for each http call( application/json, test/plain etc.).
-
Define the test runner and dependency classes in grinder properties(under src/test/grinder), e,g http-get.properties:
...... java_test_runner = com.syamantakm.grinder.HttpGetTestRunner resource_classes=com.syamantakm.dao.SimpleJdbcDao;net.grinder.plugin.http.HTTPRequest;com.syamantakm.impl.HttpGetUrlProvider ..... -
grinder_pico.py will inject all the dependencies to the test runner class using PicoContainer, which is available with grinder.
.... dependent_class_prop = grinder.getProperties().getProperty('resource_classes') print dependent_class_prop dependent_classes = [] for dep_c in dependent_class_prop.split(';'): dep_class = load_class(dep_c) print dep_class dependent_classes.append(dep_class) class TestRunner: def __init__(self): pico = DefaultPicoContainer(AnnotatedFieldInjection(Resource)); for dep_class in dependent_classes: pico.addComponent(dep_class) ......
