junit和hamcrest声明

Question

我在4.10使用junit，1.3使用hamcrest-core，1.3使用hamcrest-库.我的问题是嵌入在junit 4.10中的hamcrest库和hamcrest核。那junit 4.11呢？

    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.10</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.hamcrest</groupId>
        <artifactId>hamcrest-core</artifactId>
        <version>1.3</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.hamcrest</groupId>
        <artifactId>hamcrest-library</artifactId>
        <version>1.3</version>
        <scope>test</scope>
    </dependency>

Answer 1

如果浏览到search.maven.org，就可以搜索工件并查看它们的依赖关系。如果您使用的是Eclipse wit插件，您还可以在POM编辑器中单击依赖层次结构。

查看Maven website，您可以看到JUnit 4.11依赖于Hamcrest 1.3：

<dependencies>
    <dependency>
      <groupId>org.hamcrest</groupId>
      <artifactId>hamcrest-core</artifactId>
      <version>1.3</version>
      <scope>compile</scope>
    </dependency>
</dependencies>

Hamcrest库您必须添加自己。

Answer 2

JUnit 4.10和JUnit 4.11 (如下所示)：

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

..。船型分别为虎骨核心1.1和1.3。通过利用依赖插件的树目标(运行mvn依赖项: tree )，您可以看到这一点：

$ mvn dependency:tree

虽然这听起来很傻，但您需要包含适当的Hamcrest库艺术品来利用Hamcrest Matcher。希望这能帮上忙..。
