Prioritize test cases according to the risks they address, focusing on high-risk areas to avoid significant project issues. Continuously reassess this prioritization after each sprint or release to improve the process based on feedback and outcomes.

Get into a discussion with devs to understand their perspective and also explain the perspective which you think. This will also help in developing a trust and a collaborative work environment. We can divide our testcases into 'must have' , 'should have' and 'not so important' categories to set the priority and explain them to devs with the supporting data / evidences / data from previous experiences to come to conclusion and develop a consensus.

I start by openly discussing our perspectives and reasoning. I use data-driven insights, like past bug trends or user feedback, to highlight high-risk areas and their impact. Together, we reassess priorities, balancing critical tests with development needs. If needed, I involve the product owner to align priorities with business goals and ensure a collaborative path forward.

I discuss the importance of each test case with developers, focusing on the potential risks and impact of bugs and then agree on which tests to focus on first based on the overall project needs.

Find common ground by initiating an open discussion to align on project goals and impact-driven priorities. Use data from risk assessments and user needs to back your reasoning. Foster collaboration by involving developers in test planning to build mutual understanding and trust.

Navigating prioritization conflicts with developers requires fostering open communication by discussing the rationale behind test case priorities, actively listening to their perspectives, aligning both teams on shared project objectives to emphasize the broader impact of testing decisions, and using data-driven insights such as metrics or past defect trends to substantiate the criticality of specific test cases, thereby creating a collaborative environment where decisions are informed and mutually agreed upon.

To address disagreements on test case priorities, I focus on fostering collaboration and clarity: -Schedule a team meeting to openly discuss priorities and align perspectives. -Clearly define project goals and ensure everyone understands the overall objectives. -Highlight how test case priorities depend on the features to be delivered, high-risk areas, module dependencies, and project timelines. -Emphasize logical reasoning and time limitations to establish priorities and discuss them with the development team for mutual agreement. This approach ensures a shared understanding and promotes efficient teamwork to meet project deadlines effectively.
