In addition to various implementations of static analysis, such as flow analysis, and unit testing, development testing also includes peer code review as a primary quality activity. Code review is widely considered one of the most effective defect detection and prevention methods in software development.
Combined with other test coverage methods, the aim is to develop a rigorous, yet manageable, set of regression tests. In implementing test coverage policies within a software development environment, one must consider the following: What are coverage requirements for the end product certification and if so what level of test coverage is required?
Grunt is a JavaScript task runner, a tool used to automatically perform frequent tasks such as minification, compilation, unit testing, and linting. It uses a command-line interface to run custom tasks defined in a file (known as a Gruntfile). Grunt was created by Ben Alman and is written in Node.js. It is distributed via npm. As of October ...
Node.js is a cross-platform, open-source JavaScript runtime environment that can run on Windows, Linux, Unix, macOS, and more.
