#TechAtWorldline

Geertjan Wielenga took the camera and microphone with him to the #DevBcn conference in Barcelona for the @foojay #podcast. Together with @icougil and Jonathan Vila, he spoke with many visitors about Java and development.

I had a wonderful trip to Barcelona and DevBCN! Read about it here.

Garbage Collector comparison in #java

Over 100G of memory

People are deploying apps with 2tera heap size

#DevBCN crazy people in the audience

@prpatel at #DevBCN talking about garbage collectors in #Java

The Garbage collector cleans and removes objects from the #Java memory.

To collect objects, it may stop the world (paralize the JVM), do an incremental sweep or a monolithic one.

#DevBCN

This is the working memory of #Java

The older the object, the more to the right.

#DevBCN

What is the best Garbage Collector for the cloud?

Does it really matter?

#DevBCN

Use and reuse tools

#DevBCN

@trisha_gee

The problem may not be the number of tests

#DevBCN

@trisha_gee

Yes, it is fine to delete tests

#DevBCN

@trisha_gee

A flaky test is a wrong test. You can't trust it when it is green

#DevBCN

@trisha_gee

Is the test deprecated or is the code wrong?

#DevBCN @trisha_gee

#Antipattern for #tests: what is this supposed to do?

If you compare booleans and the name does not explain what it checks, troubleshooting becomes tedious.

@trisha_gee #DevBCN

Personality types (not white and black, scales of grey)

For testing, try to find all personalities to work together.

#DevBCN @trisha_gee

Pair testing

Bring a friend

@trisha_gee #DevBCN

AI is a lying toad

#DevBCN @trisha_gee

Code generation in your IDE is predictable, it does always the same correct thing.

AI is not predictable. You have to review what it is doing every single time.

#DevBCN

First advice for good testing: Use your IDE.

Autocomplete. Use templates. Let the IDE guide you .

What slows down your #tests? #DevBCN

Testing is an anxiety reducing technique @trisha_gee #DevBCN
