Contrasting test automation and BDD - 2020
1 likeâ˘258 views
The document contrasts test automation and behavior-driven development (BDD). It discusses that while test automation focuses on testing using separate tools, BDD emphasizes interactions and collaboration. The document compares benefits and challenges of each approach and notes that both have value when used together by development teams. Confusion arises when people view BDD and test automation as the same, when they each have distinct but complementary purposes.
