1: public class Advent6: IDisposable
2: {
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.
