You didn't mention why you don't want to use foreach, but here is a way to do it with LINQ, assuming you have a single-user test that can be invoked with a function named ExecuteTestForAUser() (yours may differ):

const numberOfTests = 50;
var tasks = Enumerable.Range(1, numberOfTests)
    .Select
    ( 
        i => Task.Run( () => ExecuteTestForAUser() ) 
    )
    .ToArray();
Task.WaitAll( tasks );

This code produces a list of 50 integers using Enumerable.Range. It then converts the list into a list of 50 tasks using Select. Task.Run() will put each task on the thread pool. Then Task.WaitAll() will block execution until they have all completed.

You will need to make sure ExecuteTestForAUser() is thread-safe.
