tests make people more confident-the ideal test must be updated before the new features are added. 2. Who will write unit tests and when to compose unit tests Program code testing can be very tedious, especially when you're a programmer, particularly when it comes to testing other people's programs. But programmers like to write programs, so why not let programmers write

Java is across-platform, interpreted languageJava Source Code compilation Intermediate "bytecode" is stored in the class file. A class file is an intermediate code in the form of a bytecode that includes a lot of source code information, such as variable names, method names, and so on. Therefore, the anti-compilation of the Java intermediate code becomes very easy. There are many free, commercially availabl
