播放框架2.2.1：为测试创建Http.Context

Question

我一直在尝试使用其构造函数创建Http.Context进行测试失败。有人看到我在做什么错吗？

我看了以下内容，但仅适用于Play 2.0：

播放框架2.0：将值存储在Http.Context中

看起来该类已针对2.2.1进行了更改，并且它为构造函数提供了更多参数，如下所示：

https://github.com/playframework/playframework/blob/2.1.x/framework/src/play/src/main/java/play/mvc/Http.java

这是我的代码：

import java.util.Map;
import java.util.Collections;
import org.junit.*;
import static org.mockito.Mockito.*;
import play.mvc.*;
import play.test.*;
import play.mvc.Http;
import play.mvc.Http.Context;
import play.api.mvc.RequestHeader;
import static play.test.Helpers.*;
import static org.fest.assertions.Assertions.*;


public class TemplateTests {

    public static FakeApplication app;
    private final Http.Request request = mock(Http.Request.class);

    @BeforeClass
    public static void startApp() {
        app = Helpers.fakeApplication();
        Helpers.start(app);
    }

    @Before
    public void setUp() throws Exception {
        Map<String, String> flashData = Collections.emptyMap();
        Map<String, Object> argData = Collections.emptyMap();
        Long id = 2L;
        play.api.mvc.RequestHeader header = mock(play.api.mvc.RequestHeader.class);
        Http.Context context = mock(Http.Context(id, header, request , flashData, flashData, argData));
        Http.Context.current.set(context);
    }


    @Test
    public void renderTemplate() {
        Content html = views.html.index.render();
        assertThat(contentType(html)).isEqualTo("text/html");
        assertThat(contentAsString(html)).contains("myindex");
    }

    @AfterClass
    public static void stopApp() {
        Helpers.stop(app);
    }
}

这是运行测试时看到的错误：

play test
[info] Loading project definition from /home/user/solr-segmentexplorer/explorer/project
[info] Set current project to explorer (in build file:/home/user/solr-segmentexplorer/explorer/)

有任何想法吗？

如果不创建上下文，则会得到：

[error] Test TemplateTests.renderTemplate failed: java.lang.RuntimeException: There is no HTTP Context available from here.

Answer 1

看起来这似乎已经为我解决了：

@Before
public void setUp() throws Exception {
    Map<String, String> flashData = Collections.emptyMap();
    Map<String, Object> argData = Collections.emptyMap();
    Long id = 2L;
    play.api.mvc.RequestHeader header = mock(play.api.mvc.RequestHeader.class);
    Http.Context context = new Http.Context(id, header, request, flashData, flashData, argData);
    Http.Context.current.set(context);
}

具体修复的部分是：

Http.Context.current.set(context);
