Working in the embedded systems industry for most of my life, I can tell you methodical testing by the software engineers is significantly lacking. Compared to the higher level language development with unit tests and etc, something i think the higher level abstracted industry actually hit out the of park successfully.

The culture around unit testing and testing in general is far superior in java and the rest.

Down here in embedded all too often I hear “well it worked on my setup... it worked at my desk”.. or Oh I forgot to test that part.. or I didn’t think that perticular value could get passed in... etc I’ve heard it all. Then I’ve also heard, you can’t do TTD or unit tests like high level on embedded... HORSESHIT!

You most definitely can! This book is a great book to prove a point or use as confirmation you are doing things correctly. My history with this book was I gonna as doing my own technique of unit testing based on my experience in the high level. Was it perfect no but I caught much more than if I hadn’t done the testing. THEN I found this book, and was like ohh cool I’m glad I’m on the right thought process because essentially what they were doing in the book is what I was doing just slightly less structured and missing a few things.

I’ve seen coworkers immediately think it’s impossible to utilize host testing .. wrong.

Come to find out most the of problems actually are related to lack of abstraction or for thought out into software system design by many lone wolf embedded developers.. either being alone, or not having to think about repercussions of writing direct register writes in application or creating 1500 line “main functions” because their perception is “main = application”. (Not everyone is like this) but it seems to be related to the EEs writing code ( they don’t know wha the CS knows) and CS writing over abstraction and won’t fit on Embedded... then you have CEs that either get both sides or don’t.. the ones to understand the low level need but also get high level concepts and pariadigms and adapt them to low level requirements BOOM those are the special folks.

ANYway..the book is great because it’s a great beginner book for those embedded folks who don’t understand what TDD is or Unit testing and think they can’t do it because they are embedded. So all they do is AdHoc testing on the fly no recording results no concluding data very quick spot check and done....

If your embedded software engineers say they can’t unit test or do TDD or anything other than AdHoc Testing...Throw the book at them and say you want the unit test results report by next week Friday and walk away.

Lol

Impossible changes become possible.

Would you like to talk about our god and saviour TDD?

P.S. I like test driven development very much. It makes complex stuff really easy.

Most exited I've been about some code? Probably for some random "build a twitter clone with Rails" tutorial I found online.

I've been working on my CS degree for a while (theoretical CS) but I really wanted to mess with something a bit more practical. I had almost none web dev experience, since I've been programming mostly OS-related stuff till then (C). I started looking around, trying to find a stack that's easy to learn since my time was limited- I still had to finish with my degree.

I played around with many languages and frameworks for a week or two. Decided to go with Ruby/Rails and built a small twitter clone blindly following a tutorial I found online and WAS I FUCKING EXITED for my small but handmade twitter clone had come to life. Coming from a C background, Ruby was weird and felt like a toy language but I fell in love.

My excitement didn't fade. I bought some books, studied hard for about a month, learned Ruby, Rails, JavaScript, SQL (w/ pg) and some HTML/CSS. Only playing with todo apps wasn't fun. I had a project idea I believed might be somewhat successful so I started working on it.

The next few months were spent studying and working on my project. It was hard. I had no experience on any web dev technology so I had learn so many new things all at once. Picked up React, ditched it and rewrote the front end with Vue. Read about TDD, worked with PostgreSQL, Redis and a dozen third party APIs, bought a vps and deployed everything from scratch. Played it with node and some machine learning with python.

Long story short, one year and about 30 books later, my project is up and running, has about 4k active monthly users, is making a profit and is steadily growing. If everything goes well, next week I'll close a deal with a pretty big client and I CANT BE FKING HAPPIER AND MORE EXCITED :D Towards the end of the month I'll also be interviewed for a web dev position.

That stupid twitter clone tutorial made me excited enough to start messing with web technologies. Thank you stupid twitter clone tutorial, a part of my heart will be yours forever.

I had mentioned before I got offered a new role, with 50% increase.

I wasn’t expecting my current employer to counter, but they suddenly shat themselves and basically matched the salary, and offered promotion to software developer (sans junior). They acknowledge my role within the company is only increasing in responsibility and so far I have exceeded expectations. Its a nice response to have from them, although I do wonder how long it might have taken without the panic.

The new company have counter-countered, promising to raise salary by a further 20% of total, within the first 6 months, provided I learn React reasonably quickly (about a month), integrate with the team and start to take on my roles within the Agile set relatively independently (3-6 months). They also don’t bother with the junior role title at these pay bandings.

I currently get about half an hour a week with my lead dev on sticking issues. In this new team, I would be one of ten javascripters, working towards best practices, TDD etc. This is absolutely the realm I want to specialise in, at the first stage of my career.

I said I would stay with my current employer, before the counter counter move. Now I am full of doubt.

Has anyone landed in teams like this, only to find they didn’t offer increased learning at all? If that was a high risk for me, I wouldnt take it, despite the offer of more cash. I’d sooner get more skilled in the stuff I have been working in at my current role.

Pretty amazing how much amazing life experiences can cause anxiety. Never been in the middle of a bidding war before...

Today I escape from the clutches of the legacy iOS project ive been stuck in for about a year and a half.
Starting on a new team, totally different stack (TypeScript/Angular).
Its bad that what makes me happiest is that we have unit tests, something thats been missing from my life for so long now. I might actually get to do TDD now.
Life is good.

Just sat the shittiest exam of my life yesterday. It involved among other things: TDD with java (on paper), critiquing and rewriting gherkin scenarios, and diagnosing problems with agile teams based on a limited description. I was short for time at the end and chose not to answer some questions because it would tire my hand too much to attempt them, and it's time consuming af to edit stuff you wrote down.

Many other exams are switching to online tests, and this one really could have benefited from that given the sheer volume of crap I had to write down.

I'm basically hoping to God that I didn't fail this thing, but the lowest exam grade I've had so far is 70 so it would be crazy if I did. Still, fuck these people for writing such a difficult exam.
