"""Builder for Junit test results.
Junit is impossible to stream out, it requires attributes counting the
total number of tests, failures, skips, and errors in the root element
and in each test suite. As such, we use a builder class to track each
test case, and calculate all metadata before writing it out.
For tests with multiple results (like from a TAP test), we record the
test as a suite with the project_name.test_name. This allows us to track
each result separately. For tests with only one result (such as exit-code
tests) we record each one into a suite with the name project_name. The use
of the project_name allows us to sort subproject tests separately from
the root project.
