 * `tLogIndex` (optional) allows for aggregation of code coverage results across unit test runs. To use this, get it back as output from the first test run, then pass it to the next.
 * `tSourceNamespace` (optional) specifies the namespace in which classes were compiled, defaulting to the current namespace. This may be required to retrieve some metadata.
