AutoFixture, create a list of email addresses

You can use AutoFixture to create a list of email addresses by using the CreateMany method and passing in a function that generates email addresses.

Here's an example of how to do this:

using System; using System.Collections.Generic; using AutoFixture; class Program { static void Main(string[] args) { var fixture = new Fixture(); // Create a list of 10 email addresses var emailAddresses = fixture.CreateMany<string>(10, () => fixture.Create<string>() + "@example.com").ToList(); // Print the email addresses to the console foreach (var emailAddress in emailAddresses) { Console.WriteLine(emailAddress); } } }

In this example, we're creating a new Fixture object and using its CreateMany method to generate a list of 10 email addresses.

The second parameter of CreateMany is a function that generates each item in the list. We're using this function to concatenate a randomly generated string with @example.com to create a valid email address.

Finally, we're printing the email addresses to the console using a foreach loop.

Note that this approach will generate random email addresses that may not be valid or unique. If you need to generate email addresses that are guaranteed to be valid or unique, you may need to use a different approach.

Examples

    public class MyNestedClass { public List<string> NestedEmailList { get; set; } } public class MyClass { public MyNestedClass NestedObject { get; set; } } var fixture = new Fixture(); // Create a list of email addresses in an object graph var emailList = fixture.CreateMany<string>().Select(email => $"{email}@example.com").ToList(); fixture.Customize<MyClass>(c => c.With(x => x.NestedObject.NestedEmailList, emailList)); var myClassInstance = fixture.Create<MyClass>(); // 'myClassInstance.NestedObject.NestedEmailList' should contain multiple unique email addresses

    Description: Demonstrates how to create a list of email addresses within an object graph during customization.

  6. C# AutoFixture Generate Email List for Constructor Parameter

    public class MyClass { public List<string> EmailList { get; } public MyClass(List<string> emailList) { EmailList = emailList; } } var fixture = new Fixture(); // Generate a list of email addresses for a constructor parameter var emailList = fixture.CreateMany<string>().Select(email => $"{email}@example.com").ToList(); fixture.Customize<MyClass>(c => c.With(x => x.EmailList, emailList)); var myClassInstance = fixture.Create<MyClass>(); // 'myClassInstance.EmailList' should contain multiple unique email addresses
