Expectations for the file and time system from Testably.Abstractions.

File system​

You can verify that a specific file or directory exists in the file system:

IFileSystem fileSystem = new MockFileSystem();
fileSystem.Directory.CreateDirectory("my/path");
fileSystem.File.WriteAllText("my-file.txt", "some content");

await That(fileSystem).HasDirectory("my/path");
await That(fileSystem).HasFile("my-file.txt");

File​

For files, you can verify the file content:

IFileSystem fileSystem = new MockFileSystem();
fileSystem.File.WriteAllText("my-file.txt", "some content");

await That(fileSystem).HasFile("my-file.txt").WithContent("some content").IgnoringCase();
await That(fileSystem).HasFile("my-file.txt").WithContent().NotEqualTo("some unexpected content");

You can also verify the file content with regard to another file:

IFileSystem fileSystem = new MockFileSystem();
fileSystem.File.WriteAllText("my-file.txt", "some content");
fileSystem.File.WriteAllText("my-other-file.txt", "SOME CONTENT");
fileSystem.File.WriteAllText("my-third-file.txt", "some other content");

await That(fileSystem).HasFile("my-file.txt").WithContent().SameAs("my-other-file.txt").IgnoringCase();
await That(fileSystem).HasFile("my-file.txt").WithContent().NotSameAs("my-third-file.txt");

For files, you can verify the creation time, last access time and last write time:

IFileSystem fileSystem = new MockFileSystem();
fileSystem.File.WriteAllText("my-file.txt", "some content");

await That(sut).HasFile(path).WithCreationTime(DateTime.Now).Within(1.Second());
await That(sut).HasFile(path).WithLastAccessTime(DateTime.Now).Within(1.Second());
await That(sut).HasFile(path).LastWriteTime(DateTime.Now).Within(1.Second());

Directory​

For directories, you can verify that they contain subdirectories:

IFileSystem fileSystem = new MockFileSystem();
fileSystem.Directory.CreateDirectory("foo/bar1");
fileSystem.Directory.CreateDirectory("foo/bar2/baz");

await That(fileSystem).HasDirectory("foo").WithDirectories(f => f.HasCount().EqualTo(2));

For directories, you can verify that they contain files:

IFileSystem fileSystem = new MockFileSystem();
fileSystem.Directory.CreateDirectory("foo/bar");
fileSystem.File.WriteAllText("foo/bar/my-file.txt", "some content");

await That(fileSystem).HasDirectory("foo/bar").WithFiles(f => f.All().ComplyWith(x => x.HasContent("SOME CONTENT").IgnoringCase()));
