33.9. 模拟现有端点

Camel 现在允许您自动模拟 Camel 路由中的现有端点。

假设您有以下给定的路由：

Route（路由）

    @Override
    protected RouteBuilder createRouteBuilder() throws Exception {
        return new RouteBuilder() {
            @Override
            public void configure() throws Exception {
                from("direct:start").routeId("start")
                        .to("direct:foo").to("log:foo").to("mock:result");

                from("direct:foo").routeId("foo")
                        .transform(constant("Bye World"));
            }
        };
    }

然后，您可以使用 Camel 中的 建议 带功能来模拟来自单元测试给定路由中的所有端点，如下所示：

提供模拟所有端点的建议

    @Test
    public void testAdvisedMockEndpoints() throws Exception {
        // advice the start route using the inlined AdviceWith lambda style route builder
        // which has extended capabilities than the regular route builder
        AdviceWith.adviceWith(context, "start", a ->
        // mock all endpoints
        a.mockEndpoints());

        getMockEndpoint("mock:direct:start").expectedBodiesReceived("Hello World");
        getMockEndpoint("mock:direct:foo").expectedBodiesReceived("Hello World");
        getMockEndpoint("mock:log:foo").expectedBodiesReceived("Bye World");
        getMockEndpoint("mock:result").expectedBodiesReceived("Bye World");

        template.sendBody("direct:start", "Hello World");

        assertMockEndpointsSatisfied();

        // additional test to ensure correct endpoints in registry
        assertNotNull(context.hasEndpoint("direct:start"));
        assertNotNull(context.hasEndpoint("direct:foo"));
        assertNotNull(context.hasEndpoint("log:foo"));
        assertNotNull(context.hasEndpoint("mock:result"));
        // all the endpoints was mocked
        assertNotNull(context.hasEndpoint("mock:direct:start"));
        assertNotNull(context.hasEndpoint("mock:direct:foo"));
        assertNotNull(context.hasEndpoint("mock:log:foo"));
    }

请注意，模拟端点被赋予了 URI Vulnerability:& lt;endpoint>，如 模拟：direct:foo。INFO 级别的 Camel 日志是模拟的端点：

INFO  Adviced endpoint [direct://foo] with mock endpoint [mock:direct:foo]

它还可能仅使用模式模拟某些端点。例如，模拟您 执行 的所有日志端点，如下所示：

提供只使用模式的模拟日志端点 的建议

    @Test
    public void testAdvisedMockEndpointsWithPattern() throws Exception {
        // advice the start route using the inlined AdviceWith lambda style route builder
        // which has extended capabilities than the regular route builder
        AdviceWith.adviceWith(context, "start", a ->
        // mock only log endpoints
        a.mockEndpoints("log*"));

        // now we can refer to log:foo as a mock and set our expectations
        getMockEndpoint("mock:log:foo").expectedBodiesReceived("Bye World");

        getMockEndpoint("mock:result").expectedBodiesReceived("Bye World");

        template.sendBody("direct:start", "Hello World");

        assertMockEndpointsSatisfied();

        // additional test to ensure correct endpoints in registry
        assertNotNull(context.hasEndpoint("direct:start"));
        assertNotNull(context.hasEndpoint("direct:foo"));
        assertNotNull(context.hasEndpoint("log:foo"));
        assertNotNull(context.hasEndpoint("mock:result"));
        // only the log:foo endpoint was mocked
        assertNotNull(context.hasEndpoint("mock:log:foo"));
        assertNull(context.hasEndpoint("mock:direct:start"));
        assertNull(context.hasEndpoint("mock:direct:foo"));
    }

支持的模式可以是通配符或正则表达式。有关此问题的详细信息，请参阅 Intercept，及其与 Camel 使用的相同匹配功能。
