We also analyse relationship between developer experience and ownership and the number of asserts. ![]() ![]() We collect metrics such as number of asserts, number of defects, number of developers and number of lines changed to a method, and examine the relationship between asserts and defect occurrence. In this study, we perform a partial replication of the above study on a large dataset of Java projects from GitHub (185 projects, 20 million LOC, 4 million commits, 0.2 million files and 1 million methods). Their results show that asserts have a small effect on reducing the density of bugs and developers often add asserts to methods they have prior knowledge of and larger ownership. analyse C and C++ programs to understand the relationship between assertion usage and defect occurrence. Since assertions make developer assumptions explicit, assertions are also believed to improve under-standability of code. It throws an error if the expression is not satisfied, which helps developers to detect and correct bugs. ![]() An assertion contains a boolean expression which developers believe to be true at a particular program point. ![]() Assertions are often used to test the assumptions that developers have about a program.
