> 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.
