Summary:
The error message from the construct `assertTrue(a == b, "msg") ` are nearly always completely useless for actually debugging the issue.
This patch is just replacing this construct (and similar ones like `assertTrue(a != b, ...)` with the proper call to assertEqual or assertNotEquals.
This patch was mostly written by a shell script with some manual verification afterwards:
```
lang=python
import sys
def sanitize_line(line):
if line.strip().startswith("self.assertTrue(") and " == " in line:
line = line.replace("self.assertTrue(", "self.assertEquals(")
line = line.replace(" == ", ", ", 1)
if line.strip().startswith("self.assertTrue(") and " != " in line:
line = line.replace("self.assertTrue(", "self.assertNotEqual(")
line = line.replace(" != ", ", ", 1)
return line
for a in sys.argv[1:]:
with open(a, "r") as f:
lines = f.readlines()
with open(a, "w") as f:
for line in lines:
f.write(sanitize_line(line))
```
