1: namespace Advent22
2: {
3: public class FileUtil_Specification
4: {
5: private FileUtilWithDelete Given_A_Readable_File(string content)
6: {
7: FileUtilWithDelete file = new FileUtilWithDelete(“SomeFile.txt”);
8: file.Create(content);
9: return file;
10: }
11:  
12: private FileUtilWithDelete Given_An_Unreadable_File()
13: {
14: FileUtilWithDelete file = Given_A_Readable_File(“SHOULD NOT BE ABLE TO READ THIS”);
15: file.Readable = false;
16: return file;
17: }
18:  
19: [Fact]
20: public void Reading_A_Readable_File_Returns_File_Content()
21: {
22: using (FileUtilWithDelete file = Given_A_Readable_File(“CONTENT”))
23: {
24: string content = file.Read();
25: Assert.Equal<string>(“CONTENT”, content);
26: }
27: }
28:  
29: [Fact]
30: public void Reading_An_Unreadable_File_Throws_Correct_Exception()
31: {
32: using (FileUtilWithDelete file = Given_An_Unreadable_File())
33: {
34: Assert.Throws<AccessViolationException>(() => { file.Read(); });
35: }
36: }
37: }
38: }

So now we have a better name for our specification. But why should everything that has to do with FileUtil be in the same specification?
