Piotr Findeisen updated SUREFIRE-1967:
--------------------------------------
Flags: Patch
> High resource consumption when executing TestNG tests in parallel mode with a
> suite file
> ----------------------------------------------------------------------------------------
>
> Key: SUREFIRE-1967
> URL: https://issues.apache.org/jira/browse/SUREFIRE-1967
> Project: Maven Surefire
> Issue Type: Bug
> Reporter: Piotr Findeisen
> Priority: Major
>
> When executing TestNG tests with a suite file, TestNG invokes `@AfterClass`
> allowing test to free resources, before moving to next test class.
> With parallel test execution, at most number-of-thread test classes get
> initialized at a time.
> When TestNG is invoked from Surefire without a suite file, many test
> instances get initialized in sequence, without being torn down, leading to
> higher resource consumption.
> For resource hungry tests, like in Trino project
> ([https://github.com/trinodb/trino/ ),|https://github.com/trinodb/trino/),]
> this makes a big difference in resource consumption.
