使用`mvn test`参数化JUnit测试是否正确？ [英] Does Parameterized JUnit test correct with `mvn test`?

问题描述

我刚刚使用 JUnit实现了一个JUnit测试用例

I'm just implemented a JUnit test case using JUnit 4.11 following the example:

https://github.com/junit-team/ junit / blob / master / doc / ReleaseNotes4.11.md＃example-1

我使用

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <modelVersion>4.0.0</modelVersion>
    <groupId>com.yyt</groupId>
    <artifactId>example</artifactId>
    <version>0.0.1-SNAPSHOT</version>

    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.11</version>
            <scope>test</scope>
        </dependency>         
    </dependencies>

</project>

此测试案例：

import java.util.Arrays;

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import org.junit.runners.Parameterized.Parameters;

@RunWith(Parameterized.class)
public class Example {

    @Parameters(name = "{index}: fib({0})={1}")
      public static Iterable<Object[]> data() {
        return Arrays.asList(new Object[][] { { 0, 0 }, { 1, 1 }, { 2, 1 },
          { 3, 2 }, { 4, 3 }, { 5, 5 }, { 6, 8 } });
      }

    private int input;
    private int expected;

    public Example(int input, int expected) {
      this.input = input;
      this.expected = expected;
    }

    @Test
      public void test() {
      }
}

但当我使用 mvn test 进行测试时，maven说：

But when I test it using mvn test , maven said:

-------------------------------------------------------
 T E S T S
-------------------------------------------------------
There are no tests to run.

如何使其有效？

推荐答案

问题是maven的命名约定基于 maven-surefire -plugin
需要命名，如 Test.java ，测试 .java 或 TestCase *。 java 用于单元测试。对于集成测试， maven-failsafe-plugin 负责，其命名惯例为 IT * .java ， * IT.java 或 * ITCase.java 。

The problem is the naming convention of maven which is based on maven-surefire-plugin which needs a naming like Test.java, Test.java or TestCase*.java for unit tests. For integration tests the maven-failsafe-plugin is responsible which has the naming convention IT*.java, *IT.java or *ITCase.java.
