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

Installation

dotnet add package aweXpect.Testably

It does not include aweXpect itself.

At a glance

using aweXpect.Chronology; // from the aweXpect.Chronology package
using static aweXpect.Expect;

MockFileSystem fileSystem = new();
fileSystem.File.WriteAllText("let-it-be.txt", "let it be");

// verify that a file exists, together with its content
await That(fileSystem).HasFile("let-it-be.txt").WithContent("LET IT BE").IgnoringCase();

// verify the properties of the found file
await That(fileSystem).HasFile("let-it-be.txt").Which.HasLength(9);

// verify that a file does not exist
await That(fileSystem).DoesNotHaveFile("yesterday.txt");

// verify the notifications the file system raised
await That(fileSystem).TriggeredNotification(c => c.Name == "let-it-be.txt");

// verify the method calls the file system recorded
await That(fileSystem.Statistics).Recorded().File.WriteAllText().Once();

// verify how often the callback of a timer from a MockTimeSystem was executed
MockTimeSystem timeSystem = new();
ITimerMock timer = (ITimerMock)timeSystem.Timer.New(_ => { }, null, TimeSpan.Zero, 10.Milliseconds());
await That(timer).Executed().AtLeast(3.Times()).Within(5.Seconds());

A failing expectation on the file system names the path it looked for. If the file was never written, HasFile("yesterday.txt") would fail with:

Expected that fileSystem
has file "yesterday.txt",
but it did not exist
