Jasmine comes with test doubles by using spies. Mocha does not come with a test double library, and generally uses an external library like Sinon. Jasmine has a command line utility to run tests. Mocha has a command line utility to run tests. Jasmine has assertions built into it. Mocha does not have an assertions library and uses Chai for ...
Unit testing is the cornerstone of extreme programming, which relies on an automated unit testing framework. This automated unit testing framework can be either third party, e.g., xUnit, or created within the development group. Extreme programming uses the creation of unit tests for test-driven development. The developer writes a unit test that ...
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.
The Art of Unit Testing is a 2009 book by Roy Osherove which covers unit test writing for software. It's written with .NET Framework examples, but the fundamentals can be applied by any developer. The second edition was published in 2013. It has two additional chapters, as well as reorganization and updating of chapters from the first edition.
Node.js is a cross-platform, open-source JavaScript runtime environment that can run on Windows, Linux, Unix, macOS, and more. Node.js runs on the V8 JavaScript engine, and executes JavaScript code outside a web browser. Node.js lets developers use JavaScript to write command line tools and for server-side scripting.
MEAN (MongoDB, Express.js, AngularJS (or Angular), and Node.js) [1] is a source-available JavaScript software stack for building dynamic web sites and web applications. [2] A variation known as MERN replaces Angular with React.js front-end, [3] [4] and another named MEVN use Vue.js as front-end.
Unit tests created in a test-driven development environment are typically created by the developer who is writing the code being tested. Therefore, the tests may share blind spots with the code: if, for example, a developer does not realize that certain input parameters must be checked, most likely neither the test nor the code will verify ...
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?
