IDE, Integrated Development Environment\r\nAn\u00a0integrated development environment\u00a0(IDE) is a\u00a0software application\u00a0that provides comprehensive facilities to\u00a0computer programmers\u00a0for\u00a0software development. An IDE normally consists of a\u00a0source code editor,\u00a0build automation\u00a0tools and a\u00a0debugger. Most modern IDEs have\u00a0intelligent code completion.\u00a0\r\nJUnit\r\nJUnit s a\u00a0unit testing\u00a0framework\u00a0for the\u00a0Java programming language. JUnit has been important in the development of\u00a0test-driven development, and is one of a family of\u00a0unit testing\u00a0frameworks which is collectively known as\u00a0xUnit\u00a0that originated with\u00a0SUnit.\r\nTDD Test Driven Development\r\nTest-driven development\u00a0(TDD) is a\u00a0software development process\u00a0that relies on the repetition of a very short development cycle: requirements are turned into very specific\u00a0test cases, then the software is improved to pass the new tests, only. This is opposed to software development that allows software to be added that is not proven to meet requirements.
