6 years into programming and still sometimes I feel I don't know anything.

Programming life I guess.

#Rails Tip ✨

Don't know how to get started with automated tests?

- Open the app
- Choose simple feature (~ Login)
- Manually test feature
- List down things you looked at to make sure feature is working
- Now open your test file and replicate those manual steps

I am teaching about writing automated tests in my free beginner-friendly guide at Minitest Rails

The latest chapter talks about developing this mental model:

- Test manually
- Write scenarios
- Automate the steps

Check it out:

Step 3: Automate manual steps

Finally, I write automated tests using Minitest as I now know what steps to automate.

I normally write integration tests for these type of tests but system test is best for beginners since you can view tests running live in the browser.

Our dream is bringing world Rails community here for Rails Conf Nepal.

Starting a new book recommended by my Twitter friend.

I have high hopes, let's go!

[Prabin Poudel @coolprobn]

@GregMolnar I like how snappy it is all the way here in Nepal.

The previous version had some lags.

[Prabin Poudel @coolprobn]

If you don't know yet, https://t.co/22qjZmqg7G is a complete free guide.

Not because paid books/courses are bad. Many are great.

I just don’t want fellow Rails devs to struggle getting started with automated testing like I did.

If this helps even one developer, it’s worth it.

Super cool news tonight: Rails realtime now runs on the server of your choice 🔥🔥🔥

Vova’s Action Cable server adapterization PR was merged 🥳. Same Channel and Connection code, swappable runtime underneath: Falcon, Fibers, async-cable.

This is the groundwork AnyCable has been proving in production for years, now landing in Rails itself.

People credit Rails’ longevity to DX. I think the secret behind it is adapterization pattern: every layer hides a default behind an interface, so the framework absorbs each new wave of innovation without a rewrite. Others wire it up with extra services. In Rails you swap the implementation as you wish, keeping the code intact.

Two years in the making, with
@ioquatix, @matthewd and @rafaelfranca steering the reviews. Congrats @palkan_tula 🥳

#Rails Testing Tip ✨

I used to struggle with automated testing because I lacked the right mental model.

Then it clicked: a test isn’t an abstract math problem.

It’s literally just a sequence of the exact manual steps you already perform in your browser to check your work.

@Kyriakos_Pelek I already had a website but wanted to change the copy. I just fed Cursor what the app does and the direction I want to go to in future.

After a few to and fro with the Cursor, above screenshot is what I got that I liked.

[Prabin Poudel @coolprobn]

Marketing copy was always something that was very hard for me to get right.

With AI, at least I am getting copies I am happy with.

Context:
I am revamping https://t.co/91ssybszRt so I can leverage AI and market it as a starter kit instead of a generator.

[Prabin Poudel @coolprobn]

@rmcastil @mjwhansen @DeployEmpathy Thanks, I will check it out.
I need to learn marketing stuff and all.

[Prabin Poudel @coolprobn]

@jasonfried @gkunwar1 @basecamp Thanks looks like that was the issue. I thought I had already updated the app.
