Lesson: Fix Untested

Did the code lack automated testing?

Automated testing is an invaluable practice that can help prevent regressions, help document your code's behavior, and ensure quality as you develop.

They are also a ton of work. Maintaining a robust unit test suite takes discipline and devotion. And the tests are only as good as the developer: the test suite will have the same blind spots as the person who wrote them.

When examining a vulnerability, we asked curators to examine if the code fixed for a vulnerability involved some sort of automated testing. This tag is for when the code was not tested.
