There is a general problem with LO unit tests: a test may change the state of the application, which eventually influences the next test. Some stuff is cached.
In theory you would have to restart LO for each test to reset any internal state, but that would be very slow.

The other, more probable possibility, I have also faced a few times, is memory corruption. This means your failing test is actually valid, but a previous test has passed but corrupted some memory. You should run the whole test in some memory checker.
