How to convert json file to jmx file (jmeter) using java code?

Question

Tried to convert json to xml and from xml to jmx file but couldn't able to convert to jmx file. Someone please help on this to do conversion using plain java code.

Answer 1

1. You can use Jackson library in order to convert JSON to XML

    String jsonString = "" + "{\\n \\"_links\\": {\\n" + " \\"individual\\": {\\n" + " \\"href\\": \\"/individuals/matching\\",\\n" + " \\"name\\": \\"GET\\",\\n" + " \\"title\\": \\"Individual Details\\"\\n" + " },\\n" + " \\"self\\": {\\n" + " \\"href\\": \\"/individuals/matching/\\"\\n" + " }\\n" // + " }\\n" // + "}"; ObjectMapper objectMapper = new ObjectMapper(); ObjectMapper xmlMapper = new XmlMapper(); JsonNode tree = objectMapper.readTree(jsonString); String jsonAsXml = xmlMapper.writer().withRootName("RootTagName").writeValueAsString(tree);

2. You can use JMeter API to build a JMeter Test Plan from Java code, check out Five Ways To Launch a JMeter Test without Using the JMeter GUI article for detailed explanation and example code.
