java - Mvn test 正确执行所有测试但是 mvn DTest 给出错误

Question

我有一个测试用例:

import org.graph.*;
import org.junit.*;

public class TestCase_1
{
    @Test
    public void test_1() {
      System.out.println("Hello World");
      new A().bat();
    }
}

当我运行 mvn test 时，测试运行完美。

但是，当我执行

mvn -Dtest=TestCase_1 test_1

我收到以下错误:

Unknown lifecycle phase "test_1". You must specify a valid lifecycle phase or a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal>. Available lifecycle phases are: validate, initialize, generate-sources, process-sources, generate-resources, process-resources, compile, process-classes, generate-test-sources, process-test-sources, generate-test-resources, process-test-resources, test-compile, process-test-classes, test, prepare-package, package, pre-integration-test, integration-test, post-integration-test, verify, install, deploy, pre-clean, clean, post-clean, pre-site, site, post-site, site-deploy.

有没有人知道如何解决这个问题。我已尝试指定生命周期目标，但它仍然会导致相同的错误。

Answer 1

您必须按照以下命令执行测试:

所有测试用例:

mvn test

指定测试用例:

mvn -Dtest=TestCase_1 test

如果你有库'maven-surefire-plugin'，版本是 2.7.3 或更高版本。可以指定具体方法

mvn -Dtest=TestCase_1#test_1 test

请尝试一下。
