What companies use Generative AI in Software Testing?

H2K Infosys has been closely tracking how major tech companies are bringing generative AI into software testing, and honestly, the shift feels faster than most teams expected. Companies like Microsoft, Google, Amazon, and IBM now use generative AI in software testing to create test cases, detect bugs early, and improve QA workflows without slowing releases. A lot of QA engineers I’ve spoken with say AI-powered testing is cutting repetitive work dramatically. Even banking and healthcare firms are experimenting with automation tools for software testing driven by large language models. It’s no longer just innovation talk—it’s becoming part of everyday testing strategy.
