use of com.puppycrawl.tools.checkstyle.DetailAstImpl in project checkstyle by checkstyle.

the class ParenPadCheckTest method testIsAcceptableToken.

/**
 * Pitest requires us to specify more concrete lower bound for condition for
 * ParenPadCheck#isAcceptableToken as nodes of first several types like CTOR_DEF,
 * METHOD_DEF will never reach this method. It is hard to recreate conditions for
 * all tokens to go through this method. We do not want to change main code to have
 * this set ok tokens more exact, because it will not be ease to understand.
 * So we have to use reflection to be sure all
 * acceptable tokens pass that check.
