Boundary test with Raven Db

I am building a system using Web API and Raven DB.

I am writing integration tests against the external boundary of this system.

public void GetAfterPostingPollReturnsPoll()
{
    using (var client = HttpClientFactory.Create())
    {
        var poll = new
        {
            Question = "What is the answer?",
            Options = new[] { "Yes", "No", "Maybe" }
        };
        var postResponse = client.PostAsJsonAsync("", poll).Result;
        var pollLocation = postResponse.Headers.Location;
        var getResponse = client.GetAsync(pollLocation).Result;
        var actual = JsonConvert.DeserializeObject<Poll>(
            getResponse.Content
                .ReadAsStringAsync()
                .Result);
        Assert.Equal(poll.Question, actual.Question);
        Assert.Equal(poll.Options, actual.Options);
    }
}

When I submit an entry, the Controller interacts with a DocumentStore because that is how it works in production.

The trouble I am having is that the data produced in the test is never cleaned up.

Based on what I have been reading, I should use the EmbeddableDocumentStore for the purposes of my acceptance tests.

How might I use the DocumentStore normally but the EmbeddableDocumentStore when executing boundary tests like this one?
