@stuhood @benjyw I'd appreciate a double check that it's fine to delete this IT, as we already test it through unit tests.

Cycles:

pants/src/python/pants/engine/internals/build_files_test.py

Lines 342 to 358 in 124f04a

	def do_test_cycle(self, address_str: str, cyclic_address_str: str) -> None:
	scheduler = self.create_json()
	parsed_address = Address.parse(address_str)
	self.do_test_trace_message(
	scheduler,
	parsed_address,
	f"(?ms)Dependency graph contained a cycle:.*{cyclic_address_str}.* <-.*{cyclic_address_str}.* <-",
	)
	def test_cycle_self(self) -> None:
	self.do_test_cycle("graph_test:self_cycle", "graph_test:self_cycle")
	def test_cycle_direct(self) -> None:
	self.do_test_cycle("graph_test:direct_cycle", "graph_test:direct_cycle")
	def test_cycle_indirect(self) -> None:
	self.do_test_cycle("graph_test:indirect_cycle", "graph_test:one")

Imports:

pants/src/python/pants/engine/internals/build_files_test.py

Lines 440 to 472 in 124f04a

	def test_illegal_import(self) -> None:
	prelude = dedent(
	"""\
	import os
	def make_target():
	python_library()

	).encode()
	address_mapper = unittest.mock.Mock()
	address_mapper.prelude_glob_patterns = ("prelude",)
	with self.assertRaisesRegex(
	Exception, "Import used in /dev/null/prelude at line 1\\. Import statements are banned"

Not being sure about this was one of the reasons I left all this alone last week, so I'll defer to @stuhood , who already has cycles and such on the mind.

[benjyw]

But yeah, this seems fine to me!

[stuhood]

Yea, the other tests are much better. Thanks!
