In this section, we will describe different types of software testing. Various types of software testing are performed to achieve different objectives when testing a software application. You can also read about different Software Testing Techniques which can be associated with various types of software testing.

Hydrogen has three naturally occurring isotopes: H (protium), H (deuterium), and H (tritium). Other highly unstable nuclei (H to H) have been synthesized in the laboratory, but do not occur in nature. The most stable radioisotope of hydrogen is tritium, with a half-life of 12.32 years. All heavier isotopes are synthetic and have a half-life less than a zeptosecond (10sec). Of these, H is the most stable, and the least stable isotope is H .
