There is only 3, you are reading the logs wrong. I've tested it with my correct solution and following is the output: (Note that I've purposely modified the expected result from 3 to 1 to display the error)

When reading logs, expected A to equal B, whereby A is the result from your own code and B is the expected correct result of tests

Expected 1 district, found 3: expected 3 to equal 1
