[ Upstream commit e603a342cf7ecd64ef8f36207dfe1caacb9e2583 ]
We started getting a crash in BPF CI, which seems to originate from test_parse_test_list_file() test and is happening at this line:
ASSERT_OK(strcmp("test_with_spaces", set.tests[0].name), "test 0 name");
One way we can crash there is if set.cnt zero, which is checked for with ASSERT_EQ() above, but we proceed after this regardless of the outcome. Instead of crashing, we should bail out with test failure early.
Similarly, if parse_test_list_file() fails, we shouldn't be even looking at set, so bail even earlier if ASSERT_OK() fails.
