WireMock.Net supports state via the notion of scenarios. A scenario is essentially a state machine whose states can be arbitrarily assigned. Stub mappings can be configured to match on scenario state, such that stub A can be returned initially, then stub B once the next scenario state has been triggered.

For example, suppose we’re writing a to-do list application consisting of a rich client of some kind talking to a REST service. We want to test that our UI can read the to-do list, add an item and refresh itself, showing the updated list.

# Stay in the same State for a number of requests
|
||||||
|
In case you want to match a request for a certain state multiple times before moving to the next state, you can specify this. Example code:
|
||||||
|
|
||||||
|
In the above scenario, if you want to add more items to the ToDo list, like
|
||||||
|
- Fixing the car
|
||||||
|
- Cancel newspaper
|
||||||
|
|
||||||
|
And you want to move to the next state when these two requests are matched, set the `times` variable to `2` like this:
|
||||||
|
|
||||||
|
|
||||||
|
``` c#
|
||||||
|
_server
|
||||||
|
.Given(Request.Create()
|
||||||
|
.WithPath("/todo/items")
|
||||||
|
.UsingPost())
|
||||||
|
.InScenario("To do list")
|
||||||
|
.WhenStateIs("TodoList State Started")
|
||||||
|
.WillSetStateTo("Cancel newspaper item added", 2) // <-- The number of times this match should be matched before the state will be changed to the specified one.
|
||||||
|
.RespondWith(Response.Create()
|
||||||
|
.WithStatusCode(201));
|
||||||
|
```
