When I tried to unit test with IntelliJ, I was told "java.lang.OutOfMemoryError: Java heap space"

What happened

スクリーンショット 2021-01-05 14.59.43.png One day I tried to unit test java with intellij. .. ..

java.lang.OutOfMemoryError:

The error is ... When I looked it up, there was some information, but I was addicted to it, so I will leave a countermeasure as a memorandum.

What i did

This time I did two methods

The first

Menu bar> IntelliJ IED> Preferences> Compiler Added -Xmx2048m toShared build process VM options: スクリーンショット 2021-01-05 15.05.28.png This is the method that I have investigated and found the most.

The second

スクリーンショット 2021-01-05 15.09.24.png Select Modify Run Configuration at the bottom from the run button of unit test スクリーンショット 2021-01-05 15.09.41.png A screen like this will appear, so put -Xmx2048m in the VM options here and apply

Summary

When I was investigating, it seemed that there were many people who solved it with the first method, but for some reason I could not solve it without the second method, so if anyone can help I'm happy
