bazel coverage is not showing the number of functions hit/coverage #2706
Description
🐞 bug report
Affected Rule
The issue is caused by the rule: py_test.
Is this a regression?
Not sure.
Description
I have the following python library file.
def sum(a: int, b: int) -> int:
if a == 0:
return b
return a + b
def uncalled_function():
pass
The test file is the following:
import unittest
from pytestcoverage.example import sum
class ExampleTest(unittest.TestCase):
def test_example(self):
self.assertEqual(sum(1, 2), 3)
def test_example2(self):
self.assertEqual(sum(0, 2), 2)
if __name__ == "__main__":
unittest.main()
I ran bazel coverage //pytestcoverage:example_test and it produces the following .dat file.
SF:pytestcoverage/example.py
FNF:0
FNH:0
BRDA:3,0,0,1
BRDA:4,0,1,1
BRF:2
BRH:2
DA:1,1,TEm0m03zdmZoLvEEYvcd3g

LH:5
LF:6
end_of_record
It seems it's able to know which line is covered. Unfortunately it couldn't tell the number of functions that are covered. Hence 0 value on FNF and FNH. This can also be seen from genhtml lcov program.
