示例1: Catch_WithInputValue_IncompleteTaskOfSuccess_DoesNotRunContinuationAndDoesNotSwitchContexts
public Task Catch_WithInputValue_IncompleteTaskOfSuccess_DoesNotRunContinuationAndDoesNotSwitchContexts() {
// Arrange
bool ranContinuation = false;
var syncContext = new Mock<SynchronizationContext> { CallBase = true };
SynchronizationContext.SetSynchronizationContext(syncContext.Object);
Task<int> incompleteTask = new Task<int>(() => 42);
// Act
Task<int> resultTask = incompleteTask.Catch(info => {
ranContinuation = true;
return info.Handled(42);
});
// Assert
incompleteTask.Start();
return resultTask.ContinueWith(task => {
Assert.False(ranContinuation);
syncContext.Verify(sc => sc.Post(It.IsAny<SendOrPostCallback>(), null), Times.Never());
});
