-----------------------------------------
Summary: 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
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.
