In DevOps, developers and testers play an equally important role. The responsibilities of both are tangled in such a way that outsiders see them as a single team. A QA brings a developer closer to the operations teams, thus enabling transparency throughout the process. They act as a bridge where teams can collaborate and check the feasibility of a product. Once a product is deployed, the entire team works on enriching, supporting, and keeping products running, to ensure long-term success. Product reality checks are done on a real-time basis. If a QA fails to deliver, any new functional updates are a disaster waiting to happen. These quality checks help businesses to intensify the building stages of a product. QA teams bring developers and operations to a single framework, where developers are made aware of operations requirements, and operations are made aware of the developers' work. Developers share code details to testers, who in turn share them to operations teams and perform functionality tests on the code. If any bugs are detected, these are quickly highlighted and resolved in real time before impacts are made on production. Testers share their knowledge with developers, who analyze their code, thus reducing any defects. This results in high quality, fewer version changes, and increased customer satisfaction.

DevOps is a strategy to reduce time delays in the delivery of a product. When a tester and a developer are not synchronized, the product will have to conform to the requirements of one team and then the other team. The continuous deployment of an application with the latest functionality and logic needs to be intensively tested. Testers need to be made aware of code changes and prepare test cases accordingly.

With the introduction of QA teams, DevOps has successfully reduced this delay. DevOps has made it possible for developers to share their build process with testers, who, in turn, share their knowledge with developers, thus creating a system in which everyone is aware of any updates made. Operations teams are made aware of technical details that help them better understand the process. Internal flows and backend processes are now made available to testers, who can use these to pinpoint exactly where and why an issue might pop up. The QA tester is responsible for providing code fixes if any workarounds are required.
