Considering the fact that the Bible is whole list of tests that people got forced into taking, with varied results, and a whole lot of stuff being written about them, no I don't think that God is testing us any more than He has challenged political entities, clergymen (with their rate of flunk-outs its a surprise that religion is still around) bank presidents, physicists, farmers, ditch diggers etc.
When I came out to my priest (Episcopal Church) several months ago, she did point out that Trans Folk go through a Transfiguration experience, Mark 9 and Luke 9 when we realize our true selves and they begin to show outwardly, in her case referring to the fact that I have become a much different person in many ways since I began my hormones. I was on hormones for 18 months before I came out there at church, but people had seen and noticed positive changes in me and my relations with them and were wondering what was up. Some had even come to the right conclusion but were not asking me about it. All of them enjoyed it immensely. There is also an element of a Resurrection experience to it, in that we must put aside (kill) elements of our persons that were constructed for us by other people, and must take on a whole new body that has the potential for making life better for all around us.
Test no!! I agree wholly with Annah, its a gift.
