An alpha test refers to the initial testing phase of a product before it is released to a larger audience. It involves a small group of internal users testing the software for bugs, usability, and overall functionality.
Imagine you're baking a cake. The alpha test is when you taste a small portion of the batter to ensure it's sweet and moist. If it passes the alpha test, you can move on to the beta test and eventually serve the delicious cake to a wider audience.
