TestNG Version

7.8.0

Expected behavior

Data providers can run in parallel with the attribute parallel:
@dataProvider(parallel = true)
// ...
Parallel data providers running from an XML file share the same pool of threads, which has a size of 10 by default. You can modify this value in the tag of your XML file:

...

Actual behavior

TestNG seems to startup "tests" that startup the dataprovider threads, and the data provider thread count is spun up per test. So if there are 4 data-provider tests each with 10 instances, if you set the data-provider-thread-count to 10, instead of only 10 data-provider tests running in parallel, the 4 "original tests" will spin up 10 data-providers each. Setting the thread-count is how many "tests" startup the data-provider threads.
