What stars passes all five test?

In the context of stellar classification, stars that pass all five tests typically refer to those that meet the criteria for being classified as main-sequence stars, giants, or supergiants based on their luminosity, temperature, mass, composition, and size. Specific examples include stars like the Sun, which serves as a benchmark, and other well-studied stars such as Sirius A or Alpha Centauri A. These stars exhibit clear characteristics across these tests, allowing for accurate classification and understanding of their properties.
