 					<h4>Cypress: "Understanding the Testing Mindset"</h4>
 					<blockquote>It is critical to understand that testing is a mindset before we go any further. Testing methodologies, tools, frameworks, etc. are irrelevant if you first do not understand that testing is first and foremost, a mindset.
 						The reason why software development teams and QA teams are separate is because both teams view an application completely differently. Developers are responsible for building things, while QA professionals are responsible for breaking things. If developers want to write tests, they need to learn to think the way that a QA professional does and then translate that way of thinking into automated tests.</blockquote>
