Play framework 2.2.1：为测试创建Http.Context

我一直在尝试使用其构造函数为测试创建一个Http.Context失败。 有人看到我做错了吗？

我看过以下内容，但它仅适用于Play 2.0：

Play framework 2.0：将值存储在Http.Context中

看起来类更改为2.2.1，它有更多的构造函数参数，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 flashData = Collections.emptyMap(); Map 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); } } 

这是我在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/) [info] Compiling 1 Java source to /home/user/solr-segmentexplorer/explorer/target/scala-2.10/test-classes...

有任何想法吗？

如果我不创建上下文，我得到：

[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修好了：

 @Before public void setUp() throws Exception { Map flashData = Collections.emptyMap(); Map 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); } 

具体修复它的部分是：

 Http.Context.current.set(context); 

Answer 2

只是为了使用Mockito提供替代方案，只模拟你需要的东西（没有手动实例化任何类）：

 private Http.Context getMockContext() { Http.Request mockRequest = mock(Http.Request.class); when(mockRequest.remoteAddress()).thenReturn("127.0.0.1"); when(mockRequest.getHeader("User-Agent")).thenReturn("mocked user-agent"); // ... and so on. Mock precisely what you need, then add it to your mocked Context Http.Context mockContext = mock(Http.Context.class); when(mockContext.request()).thenReturn(mockRequest); when(mockContext.lang()).thenReturn(Lang.forCode("en")); return mockContext; } 

您还可以validation是否已使用这些字段：

 @Test public void testMockContext() { final Http.Context mockContext = getMockContext(); assertThat(mockContext.request()).isNotNull(); verify(mockContext).request(); final String remoteAddress = mockContext.request().remoteAddress(); assertThat(remoteAddress).isNotNull(); assertThat(remoteAddress).isEqualTo("127.0.0.1"); verify(mockContext.request()).remoteAddress(); } 

不要忘记import static org.mockito.Mockito.*

Answer 3

只是模拟上下文类解决了这个问题

 @Before public void setUp() throws Exception { Http.Context context = mock(Http.Context.class); Http.Context.current.set(context); } 

Answer 4

作为其他答案的组合：

在build.sbt ：

 libraryDependencies += "org.mockito" % "mockito-core" % "1.10.19" % "test" 

在您的测试类中：

 import play.mvc.Http; import static org.mockito.Mockito.*; @Before public void setUp() throws Exception { Http.Context context = mock(Http.Context.class); Http.Flash flash = mock(Http.Flash.class); when(context.flash()).thenReturn(flash); Http.Context.current.set(context); } 

如果您需要更多，只需Mockito的function。 如果您看到任何exception，只需检查已编译的代码。 就我而言，它位于target/scala-2.11/twirl/main/views/html/main.template.scala 。
