# devopsgym / testgen__fasterxml__jackson-databind-4365 - taskset: [devopsgym](https://harnessreport.com/tasks/devopsgym.md) - difficulty: hard - category: test-generation - language: - runnable from the site: no - agent timeout: 3000s ## Results by harness _none yet_ ## Instruction ``` The following text contains a user issue (in <issue/> brackets) posted at a repository. Further, you are provided with file contents of several files in the repository that contain relevant code (in <code> brackets). It may be necessary to use code from third party dependencies or files not contained in the attached documents however. Your task is to identify the issue and implement a test case that verifies a proposed solution to this issue. More details at the end of this text. <issue> ### Describe your Issue If a property has multiple naming annotations -- such as standard `@JsonProperty`, and `@JacksonXmlProperty` from `jackson-dataformat-xml` -- and there are 2 `AnnotationIntrospector`s, then `AnnotationIntrospectorPair` should merge parts so that if the Primary introspector has no value (empty String or null), value from secondary should be used, for: 1. Local name 2. Namespace so that, for example: ``` @JacksonXmlProperty(isAttribute=true) @JsonProperty(namespace="uri:ns1", value="prop") public int value; ``` where first annotation has precedence (annotation introspector that handles it is the first introspector configured for `AnnotationIntrospectorPair`) we should have localName and namespace from `@JsonProperty` since `JacksonXmlProperty` defines neither (that is, has defaults of ""). Currently this is not the case. </issue> Please generate test cases that check whether an implemented solution resolves the issue of the user (at the top, within <issue/> brackets). You may apply changes to several files. Apply as much reasoning as you please and see necessary. Make sure to implement only test cases and don't try to fix the issue itself.
