Java random data generator8/10/2023 ![]() ![]() random() is one of the methods among them that returns a positive double value within the range of 0.0 and 1.0 where 0.0 is inclusive, and 1.0 is exclusive. Sample Program using Fabricator API in Java import fabricator.Java Math class offers a number of methods to work on calculations such as logarithms, average, exponentiation, etc. Click on the link for detailed information. Further, it also generates various categories of data (i.e., finance, internet, location, and mobile, etc.). String phoneNumber = person.getTelephoneNumber() įabricator API will generate unique test/fake data especially for the automation scripts/tests. String streetAddress = person.getAddress().getAddressLine1() String firstName = person.getFirstName() Sample Program using JFairy API in Java import io. Jfairy API will generate unique fake/test data based on Wikipedia, to help us generate random unique fake/test data which can be fed to the application for testing. String email = faker.internet().emailAddress() String phoneNumber = faker.phoneNumber().phoneNumber() ![]() String address = faker.address().streetAddress() String lastName = faker.name().lastName() String firstName = faker.name().firstName() String fullName = faker.name().fullName() Locale locale = new Locale("en-IND") // It will generate India specific data. Sample Program using Faker API in Java import Please click on the link for detailed information. Further, test data generated can be country specific as well. By using Faker, we can generate distinct categories of data (i.e., address, color, date & time, name, phone number, etc.). Test data generated using this API can help testers in testing the application when there is a need for unique test data. Java-based APIsįaker API will generate unique fake/test data. Therefore, the solution to this problem is to use other third-party APIs available in Java and C#. Using random class, test data is not readable or meaningful as we are generating some unique random numbers and appending to the hard-coded string. String email = FullName is: " + fullName) Ĭonsole.WriteLine("The FirstName is: " + firstName) Ĭonsole.WriteLine("The LastName is: " + lastName) Ĭonsole.WriteLine("The Address is: " + address) Ĭonsole.WriteLine("The EMail is: " + email) Ĭonsole.WriteLine("The MobileNumber is: " + phoneNumber) Sample Program Using Random Class in C# using NUnit.Framework ![]() ("The Phone Number is : " + phoneNumber) String email = "email" + r.nextInt() + Full Name is : " + fullName) String streetAddress = "address" + r.nextInt() String lastName = "lastName" + r.nextInt() ![]() String firstName = "firstName" + r.nextInt() String fullName = "fullName" + r.nextInt() Sample Program Using Random Class in Java import This is extensively useful when you automate your application with Selenium / Appium using Java or C# language. Using these classes, we can get specific test data by generating a random unique number that can be appended to a string. Normally to generate the unique test data, we can use random classes available in Java and C#. There are third-party unique test data generators available in Java and C# which will also be discussed in this blog. Using this solution, test data can be managed effectively as the data does not change for each iteration. When unique test data is fed into the application depending on a third-party API, a simple solution can be generated. Especially, when the application accepts unique data and we cannot hard code the values. The primary goal of automation testing is to run the same tests/scripts across different environments and then managing the test data. And so, it becomes a tedious process to generate test data. However, when it comes to automation testing, the tool cannot have this kind of knowledge or information. That’s primarily because, in manual testing, the testers can change/create the data, they are also aware of the data changes and hold enough application knowledge. However, test data changes in manual testing aren’t as concerning as in automation testing. Test data is essential for both manual and automation testing. ![]()
