★ QA engineer evolution

★ Separation of concerns

★ Who is SDET?

Hi, I am a QA! Who I become in 8-10 years?

Developer? Scrum Master? Business Analyst?

There has always been a wall

Bringing QA inside a team has not removed it

Once requirements are clear ...

5th sprint ...

I heard Selenium is great

Do it

Why Selenium is popular?

11th sprint ...

Rely on our tests!They are … not stable

Why??!!

40 % of tests are now outdated

We have to test them manually again

This is moment Selenium stops being popular

Test automation is like a drugs good habit

An application is not a black box anymore

User Interface is not the only API

And Selenium is not the only way of testing :)

Tests can use the closest Interface

Test Pyramid follows that principle

Working with Developer

You are not a developer!

Think twice before changing production code

Responsibility Line

SDET

Developer

Do you want others trust on your tests?

Get involved into pair programming

Keep test and production code in one branch

Review pull requests

Try to understand the code and especially tests

Do not hesitate adding your comments to code

Code never lies

Separation of concerns
