This tool can be used to test all major web browsers, to be integrated into CI (continuous integration) tools, or to work with other code editors. A powerful feature o

Detailed description of karma amp; jasmine automated testing,Front-end package management tools Code reuse and reuse are an important way of quick development. However, the original code modules are scattered on various platforms, so it is hard to find them. As a result, effective management by programmers has become a major challenge. In this case, the dependency (packages, plug-ins, and tools can all be called; the essence is that others write the

This article mainly introduces how to use Jasmine and Karma to test AngularJS page programs by using Node. js is an environment that is very suitable for full-stack JavaScript development. For more information, see AngularJS, which is the best thing on JavaScript after jQuery. This is also the method that JavaScript development has always wanted. One of the main advantages of Angular is its Dependency Injection, which is very conducive to unit testing

Typescript is a free and open source programming language developed by Microsoft. It is a superset of JavaScript and essentially adds an optional static type and class-oriented object-oriented programming to the language, and its official website is http://www.typescriptlang.org/. Why to learn this language, now HTML5 strong momentum of development, as a developer at any time to focus on new things become the necessary skills. In the hand Tour develop

The rapid development of the Internet has brought unprecedented challenges to web developers. For front-end development, the front-end development ER needs to write JS is not those few lines of visual effect code. The large increase in code volume, multi-person synergy, personnel quality disparity, this requires a standard, to the normative control of the code. Jasmine as a test framework used by a front-end team, it should be shipped.1,

TypeScript is a superset of JavaScript, and TypeScript generates JavaScript code after it has been compiled. The biggest feature of TypeScript is the type, which is called TypeScript. Typed TypeScript are easier to maintain than weakly typed JavaScript.There are 7 basic type

TypeScript Type Innference (Type judgment) and typescript Type judgment TypeScript is a JavaScript superset developed by Microsoft. It is compatible with JavaScript and can load and run JavaScript code. Compared with JavaScript, TypeScript adds comments so that the compiler can understand the supported objects and func

At present, JS Unit Testing Framework has a wealth of choices, such as Buster.js, Testswarm, Jstestdriver and so on. Jasmine, as a popular JavaScript testing tool, presents the concept of BDD (Behavior Driven development) behavior-driven development, which is only about 66K, and is feature-rich, which makes it easy to write clear and concise test cases for projects. A good test framework choice for JavaScript-based projects. Installation:Download

TypeScript entry-interface, typescript entry interfaceToo many rows too many rowsIntroduction In TypeScript, an interface is used to name these types and define contracts for your code or third-party code. ▓ Interface Example: function printLabel(labelledObj: { label: string }) { console.log(labelledObj.label); } let myObj = { size: 10, label: "Siz

TypeScript-enumeration, type inference, and typescript EnumerationEnumeration You can use enumeration to define some numeric constants with names. The enum keyword is used in the same way as in C. enum Direction { Up = 1, Down = 1 Note:: An Enumeration type can have multiple enumeration members. Each enumeration member has a corresponding numeric value, which can be a constant or a calculated value.

It ' s common in Javascript for functions to accept different argument types and to also return different types. In this lesson we learn "teach ' Typescript about these dynamic functions so we can still benefit from the Powe rful static type analysis.Const GETTASKS = (taskname:string, x:any): any = { if(typeofx = = = ' function '){ return{taskname, fn:x}; } if(Array.isarray (x)) {return{taskname, deps:x}; }};const Task1= Gettasks (' taskn

We use Chrome's developer tools to debug. The source map generated by chrome allows you to debug Typescrip code while the browser is running JavaS
