Question

我正在尝试为与vertx相关的东西编写一个测试用例。

这是我的代码

import org.junit.jupiter.api.AfterAll;
import org.junit.jupiter.api.BeforeAll;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;

import io.vertx.core.Vertx;
import io.vertx.core.http.HttpClient;
import io.vertx.core.http.HttpServer;
import io.vertx.ext.unit.Async;
import io.vertx.ext.unit.TestContext;
import io.vertx.ext.unit.junit.VertxUnitRunner;

@RunWith(VertxUnitRunner.class)
public class MyJUnitTest {

static Vertx vertx;
static HttpServer server;

@BeforeAll
public static void before(TestContext context) {
    Async async = context.async();
    vertx = Vertx.vertx();
    server = vertx.createHttpServer().requestHandler(req -> req.response().end("foo")).listen(8080,
            context.asyncAssertSuccess());
    System.out.println("Service started....");
    async.complete();
}

@AfterAll
public static void after(TestContext context) {
    vertx.close(context.asyncAssertSuccess());
}

@Test
public void test1(TestContext context) {
    // Send a request and get a response
    HttpClient client = vertx.createHttpClient();
    Async async = context.async();
    client.getNow(8080, "localhost", "/", resp -> {
        resp.bodyHandler(body -> {
            context.assertEquals("foo", body.toString());
            client.close();
            async.complete();
        });
    });
}}

出现以下错误：

org.junit.jupiter.api.extension.ParameterResolutionException：没有在可执行文件[public static void remoteprocess.java.samples.MyJUnitTest.before（io.io）中为参数[io.vertx.ext.unit.TestContext arg0]注册ParameterResolver。 vertx.ext.unit.TestContext）]。在org.junit.jupiter.engine.execution.ExecutableInvoker.resolveParameter（ExecutableInvoker.java:191）在org.junit.jupiter.engine.execution.ExecutableInvoker.resolveParameters（ExecutableInvoker.java:174）在org.junit.jupiter.engine.execution.ExecutableInvoker.resolveParameters（ExecutableInvoker.java:135）在org.junit.jupiter.engine.execution.ExecutableInvoker.invoke（ExecutableInvoker.java:116）在org.junit.jupiter.engine.descriptor.ClassTestDescriptor.lambda $ invokeBeforeAllMethods $ 5（ClassTestDescriptor.java:228）在org.junit.jupiter.engine.execution.ThrowableCollector.execute（ThrowableCollector.java:40）处在org.junit.jupiter.engine.descriptor.ClassTestDescriptor.invokeBeforeAllMethods（ClassTestDescriptor.java:227）在org.junit.jupiter.engine.descriptor.ClassTestDescriptor.before（ClassTestDescriptor.java:151）处在org.junit.jupiter.engine.descriptor.ClassTestDescriptor.before（ClassTestDescriptor.java:61）在org.junit.platform.engine.support.hierarchical.HierarchicalTestExecutor.lambda $ execute $ 3（HierarchicalTestExecutor.java:80）中在org.junit.platform.engine.support.hierarchical.SingleTestExecutor.executeSafely（SingleTestExecutor.java:66）在org.junit.platform.engine.support.hierarchical.HierarchicalTestExecutor.execute（HierarchicalTestExecutor.java:77）在org.junit.platform.engine.support.hierarchical.HierarchicalTestExecutor.lambda $ null $ 2（HierarchicalTestExecutor.java:92）中在java.util.stream.ForEachOps $ ForEachOp $ OfRef.accept（未知来源）在java.util.stream.ReferencePipeline $ 2 $ 1.accept（未知来源）在java.util.Iterator.forEachRemaining（未知来源）在java.util.Spliterators $ IteratorSpliterator.forEachRemaining（未知来源）在java.util.stream.AbstractPipeline.copyInto（未知来源）在java.util.stream.AbstractPipeline.wrapAndCopyInto（未知来源）在java.util.stream.ForEachOps $ ForEachOp.evaluateSequential（未知源）在java.util.stream.ForEachOps $ ForEachOp $ OfRef.evaluateSequential（未知源）在java.util.stream.AbstractPipeline.evaluate（未知来源）在java.util.stream.ReferencePipeline.forEach（未知来源）在org.junit.platform.engine.support.hierarchical.HierarchicalTestExecutor.lambda $ execute $ 3（HierarchicalTestExecutor.java:92）中在org.junit.platform.engine.support.hierarchical.SingleTestExecutor.executeSafely（SingleTestExecutor.java:66）在org.junit.platform.engine.support.hierarchical.HierarchicalTestExecutor.execute（HierarchicalTestExecutor.java:77）在org.junit.platform.engine.support.hierarchical.HierarchicalTestExecutor.execute（HierarchicalTestExecutor.java:51）在org.junit.platform.engine.support.hierarchical.HierarchicalTestEngine.execute（HierarchicalTestEngine.java:43）处在org.junit.platform.launcher.core.DefaultLauncher.execute（DefaultLauncher.java:170）在org.junit.platform.launcher.core.DefaultLauncher.execute（DefaultLauncher.java:154）在org.junit.platform.launcher.core.DefaultLauncher.execute（DefaultLauncher.java:90）在org.eclipse.jdt.internal.junit5.runner.JUnit5TestReference.run（JUnit5TestReference.java:86）在org.eclipse.jdt.internal.junit.runner.TestExecution.run（TestExecution.java:38）在org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests（RemoteTestRunner.java:538）在org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests（RemoteTestRunner.java:760）在org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run（RemoteTestRunner.java:460）在org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main（RemoteTestRunner.java:206）禁止：org.junit.jupiter.api.extension.ParameterResolutionException：在可执行文件[public static void remoteprocess.java.samples.MyJUnitTest.after（io.vertx）中未为参数[io.vertx.ext.unit.TestContext arg0]注册ParameterResolver .ext.unit.TestContext）]。在org.junit.jupiter.engine.execution.ExecutableInvoker.resolveParameter（ExecutableInvoker.java:191）在org.junit.jupiter.engine.execution.ExecutableInvoker.resolveParameters（ExecutableInvoker.java:174）在org.junit.jupiter.engine.execution.ExecutableInvoker.resolveParameters（ExecutableInvoker.java:135）在org.junit.jupiter.engine.execution.ExecutableInvoker.invoke（ExecutableInvoker.java:116）在org.junit.jupiter.engine.descriptor.ClassTestDescriptor.lambda $ null $ 6（ClassTestDescriptor.java:242）在org.junit.jupiter.engine.execution.ThrowableCollector.execute（ThrowableCollector.java:40）处在org.junit.jupiter.engine.descriptor.ClassTestDescriptor.lambda $ invokeAfterAllMethods $ 7（ClassTestDescriptor.java:241）在java.util.ArrayList.forEach（未知来源）在java.util.Collections $ UnmodifiableCollection.forEach（未知来源）在org.junit.jupiter.engine.descriptor.ClassTestDescriptor.invokeAfterAllMethods（ClassTestDescriptor.java:241）在org.junit.jupiter.engine.descriptor.ClassTestDescriptor.after（ClassTestDescriptor.java:162）在org.junit.jupiter.engine.descriptor.ClassTestDescriptor.after（ClassTestDescriptor.java:61）在org.junit.platform.engine.support.hierarchical.HierarchicalTestExecutor.lambda $ execute $ 3（HierarchicalTestExecutor.java:96）中 ...另外27个

请帮助解决此问题。

问题是您没有用vertx信息“包装”文本。请检查文档：

https://vertx.io/preview/docs/vertx-junit5/java/

此外，您还应该使用注释@ExtendWith（VertxExtension.class）在方法中使用该参数。

没有为参数[io.vertx.ext.unit.TestContext arg0]
