---------------------------------------
Summary: Implementation of TestNG "threadCount" option improperly
overrides default value
Key: SUREFIRE-2075
URL: https://issues.apache.org/jira/browse/SUREFIRE-2075
Project: Maven Surefire
Issue Type: Bug
Components: TestNG support
Reporter: Scott Babcock
The implementation in *TestNGMapConfigurator* for the [threadCount] option
injects a fixed default value of 1 if the plugin configuration does not
explicitly specify this setting. This is unnecessary and undesirable, because
TestNG provides a default value of 5 for [threadCount]. Also, this injected
default value of 1 contradicts the Surefire
[documentation|https://maven.apache.org/surefire/maven-surefire-plugin/examples/testng.html#Running_Tests_in_Parallel],
and it results in sequential execution if any of the [parallel] modes are
specified but [threadCount] is unspecified.
The solution is to allow TestNG to provide the default [threadCount] value if
the configuration omits this setting.
