   3:          private IFileUtil m_file;

   5:          public Advent6()
   6:          {
   7:              m_file = new FileUtil("SomeFile.txt");
   8:              m_file.Create("CONTENT");
   9:          }
  10:   
  11:          public void Dispose()
  12:          {
  13:              m_file.Delete();
  14:          }

  16:          [Fact]
  17:          public void TestReadOK()
  18:          {
  19:              Assert.DoesNotThrow(() => { m_file.Read(); });
  20:          }
  21:   
  22:          [Fact]
  23:          public void TestReadFails()
  24:          {
  25:              m_file.Readable = false;
  26:              Assert.Throws<AccessViolationException>(() => { m_file.Read(); });
  27:          }
  28:      }

With some redundant code broken out into the common setup method (the default constructor if you're not familiar with Xunit.net) there is another thing that bothers me about the TestReadOK-test. We're not actually verifying the content of the file. Let's fix that in the next version of this test.
