Whether conditional reasoning in any type of CR Ques, like Consitional Reasioning in Assumption, Conditional Reasoning in Weaken/Strengthen, Conditional Reasoning in Must Be True Ques, is tested on GMAT?

Powerscore GMAT CR Bible does not include Conditional Reasoning Topic in their GMAT Book but included in their LSAT Book. But they included the examples in GMAT CR Book from Conditional Reasoning which is in their LSAT Book

Please clarify.
