Now that the basic syntax has been covered, we will start building the JSON DataProvider method. First, we need a file I/O method to read the JSON data from a file. The parameter to the method will be the filename, including the path and string type. The method will be static and return JSONObject. Here is the code sample:
/**
* extractData_JSON - method to extract JSON data from a file
*
* @param file (including path)
* @return JSONObject
* @throws Exception
*/
public static JSONObject extractData_JSON(String file) throws Exception {
FileReader reader = new FileReader(file);
JSONParser jsonParser = new JSONParser();
return (JSONObject) jsonParser.parse(reader);
}
In cases where users might want to extract only specific sets of JSON data, as when filtering for specific test cases, they could create a wrapper method around the extractData_JSON...
