The document discusses different types of software testing including performance testing, A/B testing, security testing, reproducibility testing, development testing, and regression testing. It notes that while testing is often associated with testers and developers, many computer scientists also write code and should write tests for the code they produce. The document suggests looking at implications for writing tests and provides some numbers related to the cost of writing tests.

Different kinds of testing
Surely most of you are thinking:
“Testing? This is for testers!”
There are a lot of different kinds of software tests:
1. Performance testing
2. A/B testing
3. Security testing
4. Reproducibility testing
5. Development testing
6. Regression testing

However, how many of you, have written a line of code
during last month?
