如何在吊索模型中锁定RequestAttribute值 [英] How to Mock a RequestAttribute value in Sling Model

问题描述

我有一个适应@Model(Adapables=SlingHttpServletRequest.class)的吊索模型，并且有一个请求属性

@RequestAttribute @可选 私有布尔值isRegister=FALSE；

现在我想模拟上面的参数，并使用True/False值测试代码。为此，我尝试了以下方法，但均未奏效

   // register adapter factory
    BundleContext bundleContext = MockOsgi.newBundleContext();
    MockSling.setAdapterManagerBundleContext(bundleContext);
    // prepare sling request
    ResourceResolver resourceResolver = MockSling.newResourceResolver(bundleContext);
    MockSlingHttpServletRequest request = new 
    MockSlingHttpServletRequest(resourceResolver);
    request.setAttribute("isRegistration", "true");
     

和

    @Mock
    SlingHttpServletRequest slingHttpServletRequest;                             
    @Mock
    RequestParameter requestParameter;
Mockito.when(slingHttpServletRequest.getRequestParameter("isRegistration")).thenReturn(requestParameter);
        Mockito.when(requestParameter.getString()).thenReturn("true");

有没有其他方法来模拟这些类型的变量，或者我在这里漏掉了什么？

推荐答案

使用Mockito进行Sling/AEM JUnit测试不会有多大效果。模仿一个相当复杂的产品将是一个永无止境的故事--只是为了你的Sling模型中的几行代码。

最好使用Sling Mocks或AEM Mocks！

那么您的吊带型号：

import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.models.annotations.Default;
import org.apache.sling.models.annotations.Model;
import org.apache.sling.models.annotations.injectorspecific.RequestAttribute;

@Model(adaptables = SlingHttpServletRequest.class)
public class TestModel1 {

    @RequestAttribute
    @Default(booleanValues = false)
    private boolean isRegistration;

    public boolean isRegistration() {
        return isRegistration;
    }
}

可以使用这个基于Sling Mock的JUnit测试进行测试。AEM模拟几乎是相同的，只是它还提供了许多AEM服务和功能来进行测试。

import static org.junit.Assert.*;

import org.apache.sling.models.factory.ModelFactory;
import org.apache.sling.testing.mock.sling.junit.SlingContext;
import org.junit.Before;
import org.junit.Rule;
import org.junit.Test;

public class TestModel1Test {

    @Rule
    public final SlingContext context = new SlingContext();

    private ModelFactory modelFactory;

    @Before
    public void setUp() {
        context.addModelsForClasses(TestModel1.class);
        this.modelFactory = context.getService(ModelFactory.class);
    }

    @Test
    public void isRegistrationTrue() {
        context.request().setAttribute("isRegistration", true);
        TestModel1 model = modelFactory.createModel(context.request(), TestModel1.class);
        assertTrue(model.isRegistration());
    }

    @Test
    public void isRegistrationFalse() {
        context.request().setAttribute("isRegistration", false);
        TestModel1 model = modelFactory.createModel(context.request(), TestModel1.class);
        assertFalse(model.isRegistration());
    }

    @Test
    public void isRegistrationDefault() {
        TestModel1 model = modelFactory.createModel(context.request(), TestModel1.class);
        assertFalse(model.isRegistration());
    }
}

PS：不确定您是否真的想在您的模型中使用@RequestAttribute注入器。它在Sling中不是查询参数。有关详细信息，请参阅here。

那么您的SlingModel应该是

import java.util.Optional;

import org.apache.commons.lang3.BooleanUtils;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.request.RequestParameter;
import org.apache.sling.models.annotations.Model;
import org.apache.sling.models.annotations.injectorspecific.Self;

@Model(adaptables = SlingHttpServletRequest.class)
public class TestModel2 {

    @Self
    private SlingHttpServletRequest request;

    public boolean isRegistration() {
        return Optional.of(request)
                .map(req -> req.getRequestParameter("isRegistration"))
                .map(RequestParameter::getString)
                .map(BooleanUtils::toBooleanObject)
                .orElse(false);
    }
}

测试将是：

import static org.junit.Assert.*;

import org.apache.sling.models.factory.ModelFactory;
import org.apache.sling.testing.mock.sling.junit.SlingContext;
import org.junit.Before;
import org.junit.Rule;
import org.junit.Test;

public class TestModelTest2 {

    @Rule
    public final SlingContext context = new SlingContext();

    private ModelFactory modelFactory;

    @Before
    public void setUp() {
        context.addModelsForClasses(TestModel2.class);
        this.modelFactory = context.getService(ModelFactory.class);
    }

    @Test
    public void isRegistrationTrue() {
        context.request().setQueryString("isRegistration=true");
        TestModel2 model = modelFactory.createModel(context.request(), TestModel2.class);
        assertTrue(model.isRegistration());
    }

    @Test
    public void isRegistrationFalse() {
        context.request().setQueryString("isRegistration=false");
        TestModel2 model = modelFactory.createModel(context.request(), TestModel2.class);
        assertFalse(model.isRegistration());
    }

    @Test
    public void isRegistrationDefault() {
        TestModel2 model = modelFactory.createModel(context.request(), TestModel2.class);
        assertFalse(model.isRegistration());
    }
}

这是运行代码所需的最小pom.xml
