You can check all previous releases with source code here. You can get all the downloads from My Github Page README Section. Online test data generator Here you can generate up to 100 combinations of data formats and information and export up to 100,000 records.Prevent Overwrite of files if another file is already present in that locations with same name.Prevent Overwrite of Files with same name.File Name auto correcting(removing unaccepted charecters while naming).Table based Generations adding Comments.Template based, So you can use the same template for several test cases.Now You can go back to generate a few more or Restart it completely About Features List with Upcoming Features I am going to use this json file which has 6 variables example The structure of the document can be defined by the user manually or imported from existing JSON file. This is the step where you have to define the test cases that needs to be created. DTM Data Generator for JSON is a utility for developers and QA engineers who need to generate test JSON documents in a bulk manner for software or service testing purposes. You can also concatenate variables together or with other strings as shown in the below example.Ĭlick on the Select File Button and select the JSON template file that you created in your previous step. Note : For all Data Types( string, int, float, bool or null), enclose the mapped variables inside double quotes as shown in the above example. In the above example there are 6 variables initialized which are marked in bright green. You can initialize the variables by remapping then in the pattern $variableName$. To initialize all the variablesto the Application, the JSON File needs to be prepped. Free online tool to generate a random JSON file with any number of values. A collection of free online tools, utilities, and libraries that will help developers, testers, designers, in their day to day tasks. However, RANDOM_OPTIONALS is great when fuzzing your parsing code, as it will help you test different permutations of combining optional fields.You can use the JSON Test Case Generator to generate many JSON files in a controlled manner From HTML, XML, and JSON formater and converters, to robust test data generators we have all. This can make unit tests in-deterministic, as it will trigger different code paths every time. A test data generator can help you create dummy data for things like user profiles, credit card data. RANDOM_OPTIONALS will make the generator randomly generate non-required fields in the schema. This is great for testing purposes in your application. This is great for validating that your code works fine without all optional fields. I dont know the json-module so well, but the writing would be something like: length 1000000 fpg fakepersongenerator (length) with open s. This is great for validating that your code can parse all optional fields.ĮXCLUDE_OPTIONALS will make sure that no non-required fields in the schema will ever be generated. INCLUDE_OPTIONALS will make sure that all non-required fields in the schema will always be generated. You can control the behaviour of generating optional fields by setting GeneratorOptions.INCLUDE_OPTIONALS, GeneratorOptions.EXCLUDE_OPTIONALS or GeneratorOptions.RANDOM_OPTIONALS. With this option set, the JSON generator ensures that the produced JSON will validate properly against the schema. If GeneratorOptions.NO_EXAMPLES is set, the JSON will be populated with a random value that fulfills the requirements set by the JSON Schema (for example min and max length and patterns). That means that if your examples are incorrect, it will produce a JSON that does not validate properly against the schema. When USE_EXAMPLES is used, the generator disregards any other requirements set by the JSON schema (for example, you could provide an example string that does not fulfill the min and max length restrictions of the JSON schema). If GeneratorOptions.USE_EXAMPLES is set, any examples provided in the JSON schema will be used for that field when generating JSON. uniqueItems (could in rare cases sometimes generate a list that is less than maxItems long)Įxamples can be created by adding a tag in the description of the json schema.Īn example can be used to get more deterministic behaviour of tests.multipleOf (kind of, could generate overflowing numbers if no maximum is set).required attributes (80% chance that non-required attributes are included).build( schema) JSON Schema Support Supported Things JSONObject schemaObject = new JSONObject( new JSONTokener( schemaData))
