Out of Memory Error From Large Screenshots

Sintrias commented 5 years ago

I really like this tool so far. The only issue I see now from it is that when a page is large and in turn the image is large, it causes an Out of Memory Error even with 1GB of reserved memory. I don't suppose there is any way to store the image in a file a little at a time to avoid this issue.

@osyanin which memory options do you use for your Java process running tests?

osyanin commented 4 years ago

org.gradle.jvmargs=-Xmx16g -Xms4g -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
systemProp.junit.jupiter.execution.parallel.enabled=true
systemProp.junit.jupiter.execution.parallel.mode.default=concurrent
systemProp.junit.jupiter.execution.parallel.mode.classes.default=concurrent
systemProp.junit.jupiter.execution.parallel.config.strategy=dynamic
systemProp.junit.jupiter.execution.parallel.config.dynamic.factor=2

Environment: Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz with 4 core and hyperthreading, and 32 gb of RAM + ssd hard drive

@osyanin org.gradle.jvmargs specifies the JVM arguments used for the Gradle Daemon, not for tests, see https://docs.gradle.org/current/userguide/build_environment.html for more details.

For tests configuration options check https://docs.gradle.org/current/dsl/org.gradle.api.tasks.testing.Test.html
