具有测试注释的方法的java Ignore PMD规则

Question

我将PMD用于包含^{}测试的Spring引导项目。该类强制用户捕获一般Exception

class MockMvc {
    public ResultActions perform(RequestBuilder requestBuilder) throws Exception {}
}

这种用法会导致PMD错误-SignatureDeclareThrowsException。我想取消对所有@Test方法的检查。因此，我试图遵循Stackoverflow answer，但配置更改没有效果

<rule ref="rulesets/java/strictexception.xml/SignatureDeclareThrowsException" >
    <properties>
        <!-- Ignore @Test methods -->
        <property name="violationSuppressXPath" value="
        //ClassOrInterfaceBodyDeclaration/Annotation/MarkerAnnotation//Name[@Image='Test']" />
    </properties>
</rule>

我怎样才能做到呢

抽象语法树显示了测试方法的以下子树

> ClassOrInterfaceBodyDeclaration
  > Annotation
    > MarkerAnnotation
      > Name:Test
  > MethodDeclaration:(public)
    > ResultType:(void)
    ...

Answer 1

测试方法的具体问题可以在具有IgnoreJUnitCompletely属性的版本中解决

<!  PMD > version 6.*  >
<rule ref="category/java/design.xml/SignatureDeclareThrowsException" >
    <properties>
        <property name="IgnoreJUnitCompletely" value="true" />
    </properties>
</rule>

在PMD 6之前，必须从typeresolution.xml获取规则，但不能从strictexception.xml获取规则

<!  PMD > version 4.*  >
<rule ref="rulesets/java/typeresolution.xml/SignatureDeclareThrowsException">
    <properties>
        <property name="IgnoreJUnitCompletely" value="true" />
    </properties>
</rule>

但它没有回答关于violationSuppressXPath问题的问题

从PMD documentation开始，JUnit4Test应该使用TestAnnotation部分

//ClassOrInterfaceDeclaration[
   matches(@Image, $testClassPattern)
    or ExtendsList/ClassOrInterfaceType[pmd-java:typeIs('junit.framework.TestCase')]]

/ClassOrInterfaceBody/ClassOrInterfaceBodyDeclaration[MethodDeclaration[@Public=true()]/MethodDeclarator[starts-with(@Image, 'test')]]
[not(Annotation//Name[pmd-java:typeIs('org.junit.Test')])]

建议Annotation//Name[pmd-java:typeIs('org.junit.Test')]就足够了
