Angular Unit Testing
Duration : 00:03:30
Unit Testing
Unit testing in Angular involves testing individual units of code, such as components, services, and pipes, in isolation to ensure they work as expected.Example
ng test
Integration Testing
Integration testing in Angular verifies the interactions between different units of an application, ensuring they work together correctly.Example
ng test --include="**/*.integration.spec.ts"
Tools and Technologies
Angular development often relies on tools and technologies like Angular CLI, TypeScript, RxJS, and Angular Material for building robust and scalable web applications.Writing First Test Case
Writing the first test case in Angular is a crucial step in setting up a testing environment for your application.Isolated Testing
Isolated testing in Angular involves testing components, services, or other units of code in isolation, using mock dependencies when necessary.Pipe
Pipes in Angular are used to transform data before displaying it in the template. Testing pipes ensures that data transformation is done correctly.Service
Angular services are responsible for providing shared functionality across an application. Testing services ensures they perform their tasks accurately.Component
Components are the building blocks of Angular applications. Testing components ensures that they render correctly and respond to user interactions as expected.Integration Testing (Service)
Integration testing for services in Angular checks how they interact with other parts of the application and external dependencies.Integration Testing (Component)
Integration testing for components in Angular ensures that they function correctly in conjunction with their templates and any child components.Router
An Angular Router is used for navigating between different views or components in an application. Testing routing ensures proper navigation behavior.Component With Form
Testing components with forms in Angular involves verifying the functionality of forms, form controls, and their interaction with the component logic.Directive Testing
Directives in Angular allow you to manipulate the DOM. Testing directives ensure they apply the desired behavior to the elements they are attached to.Code Coverage
Code coverage tools help you determine which parts of your codebase are covered by tests. Angular projects can use tools like Istanbul to measure code coverage.Debugging
Debugging in Angular involves using tools like browser developer tools, Angular CLI's debugging features, and various debugging techniques to identify and fix issues in your application.Still have some questions? Let's discuss.
