Do read the first part before you continue to read this.
We stopped at the stack last time and now what remains is the evaluation part. Most of
you would be like, why another post for just the evaluation part , why not just add it
into the first part?
The reason is that while the post is targeted towards the developer’s role in each
phase, this phase has a few ways to do things and I wanted to go through each one of
The developers role stays constant here , mostly in the boundaries of bug fixing and solution hacking things that need to be handled right before the initial launch or whatever phases the product is to go through before the targeted users get to it.
These are the one’s I’ve worked with and there’s obviously better or worse ways to evaluate but these are based on just my knowledge at this point, as that changes, you can expect a better post later on.
To be fair, there’s like a lot of these,
these are all good but we have to understand where each works and where the other would be a better alternative.
If there’s other that you wish I cover on , do consider emailing or reaching me out on my twitter handle
UAT (User Acceptance Testing) - one of the first methods that I learned about through the first startup I worked for and it worked fine, other than that people took it very seriously and would fix and deploy things in such a hurry that it would normally need a few rounds of deploy to see them finally rest, which while is okay, I guess a bit of unit testing would’ve reduced but then it was a very small startup and the deadlines were hard and I need to find better excuses.
Anyway, the point of uat is to make sure the user’s actually understand the app and it makes sense to their business logic (in B2B) or is intuitive enough for users to browse through easily (in B2C).
These are more like things people end up doing and barely an issue with the evaluation method itself.
Solution: Calm down humans! It’s just an evaluation phase, the point of it is to break!
Solution: Docker, K8s, They exist for a reason, use them!
Saw this one coming, didn’t you?
This is something I picked up a while back without knowing what it was called. Readers know that I build tools very specific to my requirements and then 90% of the time I’m the one using them and this is the basic principle of dogfooding.
The builders of the product/tool/app use the app internally before the publish/go live.
This is something basecamp has been doing from the start and the evaluation method works but requires a good version management to go with it to work.
Version management discipline will make sure you have checkpoints throughout the codebase to identify what’s still under evaluation and what is stable enough to move forward with.
If you are using semver a good way is to handle it with pre-release tags which look a little something like:
which translates to “this is the
alpha.2 version before the
0.0.1 release and not the
This gives you a set of idea that everything that’s in alpha is being evaluated and everything with a stable non-alpha tag is being used on the stable releases.
This also means that you don’t have to hurry the to fix something, but go through the alpha releases slowly to make sure the defects are at a minimum in the stable releases.
Bugs are inevitable, there’s always a corner case, there’s always a library that decided to change something, there’s always a new requirement. Don’t rush to fix the bugs and never fix them with the first solution that comes to your mind, go through the problem, check if it’s a problem at the implementation you are looking or is something else the root of the issue.
All code is buggy. It stands to reason, therefore, that the more code you have to write the buggier your apps will be.

A lot of people depend on various automations for UI testing and API testing and I’ve talked about this before in a post about testing where I talk about how I do it and in terms of whether I like this or not, here’s a single line answers.
Doesn’t work when requirements change constantly, you are better off manually testing this instead.
That statement aside, you should still make it a habit to write tests for your API’s if you have the luxury of an open deadline. If on a hard deadline, you can spend that time on actually writing that feature to be as robust as possible.
