The deliberate use of understanding and perspective-taking as a core testing skill, applied both to the people a product is built for and the people it is built with. For users, it means stepping into their shoes to anticipate how a real person will experience an application. For colleagues, it means reading the moods, communication styles, and unspoken signals of developers and other team members to build trust and choose how and when to deliver feedback.It is often paired with an awareness of boundaries, since absorbing others' frustration without limits can lead to exhaustion. For example: raising a possible bug in a private message rather than calling it out publicly; noticing a teammate is having a difficult day and adjusting your approach; or testing a feature against how a non-technical user would actually behave rather than an idealised path.
