![]() With Mockaroo, you can design your own mock APIs, You control the URLs, responses, and error conditions. By making real requests, you'll uncover problems with application flow, timing, and API design early, improving the quality of both the user experience and API. It's hard to put together a meaningful UI prototype without making real requests to an API. Sometimes, the test fixture does not really matter to the test logic.Mock your back-end API and start coding your UI today. That's a big difference! How can this be useful ? The library will recursively populate all the object graph. Person person = new Easy Random, generating a random Person object is done with new EasyRandom().nextObject(Person.class). ![]() Person person = new Person("Foo", "Bar", Gender.MALE, address) Īnd if these classes do not provide constructors with parameters (may be some legacy types you can't change), you would write: Street street = new Street() Without Easy Random, you would write the following code in order to create an instance of the Person class: Street street = new Street(12, (byte) 1, "Oxford street") Īddress address = new Address(street, "123456", "London", "United Kingdom") In the previous example, let's suppose the Person type is defined as follows: Populating a Java object with random data can look easy at first glance, unless your domain model involves many related classes. You can of course use your own in combination with those predefined predicates. Which provides common predicates you can use in combination to define exactly which fields to exclude.Ī similar class called TypePredicates can be used to define which types to exclude from the object graph. The static methods named, ofType and inClass are defined in Exclude the field named age of type Integer in class Person.Set all fields of type String to foo (using the Randomizer defined as a lambda expression).In the previous example, Easy Random will: excludeField(named("age").and(ofType(Integer.class)).and(inClass(Person.class))) In most cases, default options are enough and you can use the default constructor of EasyRandom.Įasy Random allows you to control how to generate random data through the .Randomizer interface and makes it easy to exclude some fields from the object graph using a : EasyRandomParameters parameters = new EasyRandomParameters() Parameters to control how random data is generated: EasyRandomParameters parameters = new EasyRandomParameters()ĮasyRandom easyRandom = new EasyRandom(parameters) įor more details about these parameters, please refer to the configuration parameters section. The EasyRandomParameters class is the main entry point to configure EasyRandom instances. This method is able to generate a random instance of any arbitrary Java bean. What if you need to generate a random String? Or say a random instance of your domain object?Įasy Random provides the EasyRandom API that extends with a method called nextObject(Class type). The API provides 7 methods to generate random data: nextInt(), nextLong(), nextDouble(), nextFloat(), nextBytes(), nextBoolean() and nextGaussian(). The method EasyRandom#nextObject is able to generate random instances of any given type. Person person = easyRandom.nextObject(Person.class) Let's say you have a class Person and you want to generate a random instance of it, here we go: EasyRandom easyRandom = new EasyRandom() You can think of it as an ObjectMother for the JVM. : Easy Random v4.3.0 is now released with support for generic types and fluent setters! You can find all details in the change log.Įasy Random is a library that generates random Java objects.Please check the release notes for more details. ![]() Feature wise, this release is the same as v4.3.0.
