STORY TIME!
That Moment When I Realized...
Unit Tests Are Not Enough!
It was late at night when I got the dreaded phone call from the team lead -
"Shai... your code changes from earlier today just broke production!"
Apparently, the team decided to publish a new "hot fix" in the middle of the night (without waiting for QA)
and a change I made caused the app not to load.
I Felt So Embarrassed...
At that time I was so into "Unit Testing" and I was full of confidence because our coverage numbers were super high...
So I got up, went to my laptop and quickly commented out my changes and pushed the new version so they could publish the fix to the previous "hot fix". 
The next morning I knew that...
We MUST Start Writing E2E Tests!
- Unit Tests are "faking" reality and we also have to
check the integration between the parts - Manually checking the browser is not thorough enough(and repetitive)
- Waiting for QA slows us down!
So after lots of research of choosing the right tool, learning the syntax and starting to write and run E2E tests,
SUDDENLY we realized...
OMG! Regular E2E Tests
Are Not The Answer Either!?
If you ever tried writing "end to end" tests you know how hard they are to maintain...
Why Shai?
Because...
End 2 End Tests Are SUPER SLOW!
Spinning up a browser, DB, Docker and all the other layers your app consists of...
Plus actually running browser commands, waiting for ajax to return etc makes E2E tests run very slow compared to other type of tests... The more you add, the slower they get.
They Are The MOST FRAGILE Tests
The more code paths your tests go through and the more parts they "touch", the easier it is for them to break. And again the more tests you add, more of them break more often.
They Are The HARDEST TO DEBUG
When E2E Tests fail it can be for multiple reasons and as mentioned earlier - the more shared pieces of code a test depends on, the harder it is to locate the specific problem which causes the failure. And (yet) again - the more E2E tests you write, the harder it becomes to debug them.
They Give You a FALSE SENSE OF COVERAGE
When developers "drop" their unit testing practices in favor of more integration and E2E tests they often don't realize that in order to truly cover all of the possible scenarios your code produces, you need to write exponentially more tests as your logic grows.
But that's impossible to do, unless you want to spend all day chasing down broken tests or to wait for tests to finish running (because of the points mentioned above).
So we are NEVER really "fully covered" when we rely only on E2E tests... (unless we have like 1 million of them to test all the possible combinations of logical paths). So adding more of them wastes our time as developers without a true return on investment.
That's Why Developers End Up Not Running Them That Often
Or Just "Leave Them For QA To Deal With"...
THE SOLUTION: SMOKE TESTS
Ummm...
WHAT THE HELL ARE "SMOKE TESTS" SHAI?
glad you've asked...
Smoke Tests are few "Happy Path" tests which test only the CRITICAL user journeys of your app.
Smoke Tests Advantages Over Regular E2E Tests:
Smoke Tests Are the Most
Cost Effective E2E Strategy There Is
Because it helps you to catch faster those CRITICAL bugs... you know... the ones you have to wake up in the middle of the night (3am) to fix, or stay late at the office (8pm) because the "buy" button stopped working...

The Best Review We Got So Far
Ana Boca

"Thank you Shai for this course!
I really like the split of tactics and strategy. I also very much appreciate the thoughtfulness that goes into everything with the HiRez courses,
but specifically into the naming and metaphors.
From both a team and community perspective, having these metaphors and names (Lembas, Past Interrupting Factor, 8pm Bugs, 3am Bugs, etc...)
is far more helpful than I think people are initially inclined to realize.
We are so looking forward to utilizing this terminology in our workflow.
The organization and splitting of the different files and file extension conventions was also memorable and I'm looking forward to implementing this!"
