@xrmx could you please review the PR ? I have rebased and updated CLA

[xrmx]

Isn't this supposed to be 0?

[emdneto]

Yes. We should assert 0 spans

@emdneto
I am not finding the steps validate the testcases of the instrumentation
using tox - e earlier used to see here https://github.com/open-telemetry/opentelemetry-python-contrib
could you please help me to get those steps ?

[emdneto]

YOu can use tox -e py312-test-instrumentation-sqllite3. Use tox list to see all possible combinations

[Sunilwali679]

thanks @xrmx @emdneto
I tested for self.assertEqual(len(spans), 0) its failed
AssertionError: 2 != 0
instrumentation/opentelemetry-instrumentation-sqlite3/tests/test_sqlite3.py:115: AssertionError

as shown below

def test_noop_tracer_provider(self):
    """Should not create any spans when using NoOpTracerProvider"""
    SQLite3Instrumentor().uninstrument()
    SQLite3Instrumentor().instrument(tracer_provider=trace_api.get_tracer_provider())
    self._connection = sqlite3.connect(":memory:")
    self._cursor = self._connection.cursor()

    stmt = "CREATE TABLE IF NOT EXISTS test (id integer)"
    with self._tracer.start_as_current_span("rootSpan"):
        self._cursor.execute(stmt)
    spans = self.memory_exporter.get_finished_spans()
    self.assertEqual(len(spans), 0)

    self._create_tables()
    stmt = "INSERT INTO test (id) VALUES (?)"
    data = [("1",), ("2",), ("3",)]
    with self._tracer.start_as_current_span("rootSpan"):
        self._cursor.executemany(stmt, data)
    spans = self.memory_exporter.get_finished_spans()
    self.assertEqual(len(spans), 0)

    with self._tracer.start_as_current_span("rootSpan"), self.assertRaises(Exception):
        self._cursor.callproc("test", ())
    spans = self.memory_exporter.get_finished_spans()
    self.assertEqual(len(spans), 0)

@xrmx @xrmx i do see the other testcase validate_spans in the same file where length of the span validated by 2 self.assertEqual(len(spans), 2) one for root and other for child .

def validate_spans(self, span_name):
spans = self.memory_exporter.get_finished_spans()
self.memory_exporter.clear()
self.assertEqual(len(spans), 2)
for span in spans:
if span.name == "rootSpan":
root_span = span
else:
child_span = span
self.assertIsInstance(span.start_time, int)
self.assertIsInstance(span.end_time, int)
self.assertIsNotNone(root_span)
self.assertIsNotNone(child_span)
self.assertEqual(root_span.name, "rootSpan")
self.assertEqual(child_span.name, span_name)
self.assertIsNotNone(child_span.parent)
self.assertIs(child_span.parent, root_span.get_span_context())
self.assertIs(child_span.kind, trace_api.SpanKind.CLIENT)

I see length of span is 2 so assertion is done by 2 in the PR .

The thing is noop tracer provider shouldn't produce any outcome

[Sunilwali679]

@xrmx @emdneto ,

I have merged with latest code with noop tracer provider shouldn't produce any outcome . I ran the tox testcase its passed 100%.

Is it me or test asserts have been removed?

Yes. @Sunilwali679 I think here you should double-check the test implementation and assert 0 spans. Marking as a draft to avoid wrong merge.
