// A handy class that takes care of setting up and destroying a

// The expected usage is to make this a component of your test fixture:

// class AwesomenessTest : public testing::Test {
// public:
// virtual void SetUp() {
// test_user_share_.SetUp();
// }
// virtual void TearDown() {
// test_user_share_.TearDown();
// }
// protected:
// TestUserShare test_user_share_;
// };
//
// Then, in your tests:
//
// TEST_F(AwesomenessTest, IsMaximal) {
// ReadTransaction trans(test_user_share_.user_share());
// ...
// }
//
class TestUserShare {

// backing files that might exist on disk.
void SetUp();
// Undo everything done by SetUp(): closes the UserShare and deletes
// the backing files. Before closing the directory, this will run
// the directory invariant checks and perform the SaveChanges action
// on the user share's directory.
void TearDown();
// Save and reload Directory to clear out temporary data in memory.
