> But do you really think the runtime probe is less effective in an environment where you have a good way of interacting with the program at runtime? No matter the tool, it will be very difficult to try out all code paths to figure out what can be in that tube. The difficulty scales with the size / age of the application. Take your typical 20 years old enterprise application. Nobody from the original team is around. Whole generations of programmers worked on the project, each with their own favorite patterns / code style / level of diligence. There's a massive amount of features, half of which you don't even know about. Test coverage is spotty at best. You see some common function triggered from hundreds of places, it makes a huge difference in your ability to reason about it if you have types on the data being processed or not. |
