Right, that’s why you do integration testing (manual and automated) but are you saying therefore you should do all development inside a production environment?
That’s what doesn’t pass muster to me. Why should I work on my CSS styles in an environment with the production database? It will be much slower than just working on that package in my desktop environment with just enough scaffolding the code runs.
The problem comes about when someone does the following:
- creates python project
- pip install some_package
- import some_package
Turns out some package was already in the path but a different version
- proceeds to test and build with the assumption of some_package @ newer
- all tests pass
- ships project with requirements of some_package @ newer
Someone attempts to use the package but it doesn’t work.
