title: Faking or mocking NUnit TestContext parameters in unit tests
body: <p>I've got a concrete class which reads out a test parameter during construction in the following manner:
  nunit testcontext parameters faking</p>
  <pre><code>_ = bool.TryParse(TestContext.Parameters[TestContextParameters.FileTicketsFlag], out _fileTickets);
  </code></pre>
  <p>Here, <code>TestContext</code> is Static and <code>TestParameters</code> is a member of <code>TestContext</code>.</p>
  <p>In unit tests for the class, I'd like to be able to simulate FileTicket being set to true or false - is this possible?</p>
