# assert-raises-exception (B017)
|
|
|
|
Derived from the **flake8-bugbear** linter.
|
|
|
|
## What it does
|
|
Checks for `self.assertRaises(Exception)`.
|
|
|
|
## Why is this bad?
|
|
`assertRaises(Exception)` can lead to your test passing even if the
|
|
code being tested is never executed due to a typo.
|
|
|
|
Either assert for a more specific exception (builtin or custom), use
|
|
`assertRaisesRegex` or the context manager form of `assertRaises`.
|
|
|
|
## Example
|
|
```python
|
|
self.assertRaises(Exception, foo)
|
|
```
|
|
|
|
Use instead:
|
|
```python
|
|
self.assertRaises(SomeSpecificException, foo)
|
|
``` |
