C# (CSharp) DependencyEngine.CheckCycles Beispiele

Beispiel #1

        public void CheckCyclesShouldNotThrowWhenNoCycleExists()
        {
            engine = new DependencyEngine();
            var a = new SinglePropertyType();
            var b = new SinglePropertyType();

            engine.Assign(() => b.Value).From(() => a.Value * 2, ex => { });

            Should.NotThrow(() => engine.CheckCycles());
        }

Beispiel #2

        public void CheckCyclesShouldThrowWhenThereIsACycle()
        {
            engine = new DependencyEngine();
            var a = new SinglePropertyType();
            var b = new SinglePropertyType();

            engine.Assign(() => b.Value).From(() => a.Value * 2, ex => { });
            engine.Assign(() => a.Value).From(() => b.Value - 2, ex => { });

            var dot = engine.ToDotFormat("Title");

            Should.Throw <CycleDetectedException>(() => engine.CheckCycles())
            .Message.ShouldBe(@"1 cycles found:
a.Value --> (a.Value * 2) --> b.Value --> (b.Value - 2) --> a.Value");
        }

Beispiel #3

        public void CheckCyclesShouldThrowWhenThereAreTwoCycles()
        {
            engine = new DependencyEngine();
            var a = new SinglePropertyType();

            engine.Assign(() => c.Value).From(() => d.Value - 2, ex => { });

            Should.Throw <CycleDetectedException>(() => engine.CheckCycles())
            .Message.ShouldBe(@"2 cycles found:

c.Value --> (c.Value * 2) --> d.Value --> (d.Value - 2) --> c.Value");
