| 23 | +Before I even get started on Cypress and Angular, I have to say the new design on [Angular.dev](https://angular.dev) looks incredible. It is full on conference season so I hope that they printed some kick ass [custom-stickers](https://www.stickermule.com/custom-stickers) from [Sticker Mule](https://www.stickermule.com/) and are bringing them out to Vegas! |

| 25 | +## Cypress JavaScript Testing |
| 26 | + |
| 27 | +[Cypress](https://www.cypress.io/) is a popular JavaScript end-to-end testing framework. It is known for being easy to use and fast. Cypress is also able to test Angular components. |
| 28 | + |
| 29 | +**What is Angular component testing?** |
| 30 | + |
| 31 | +Angular component testing is a type of testing that ensures that Angular components are working correctly. Angular components are the basic building blocks of Angular applications. They encapsulate HTML, CSS, and JavaScript code. |
| 32 | + |
| 33 | +**Why use Cypress for Angular component testing?** |
| 34 | + |
| 35 | +There are many reasons to use Cypress for Angular component testing. Some of the benefits include: |
| 36 | + |
| 37 | +- Cypress is easy to use and learn. |
| 38 | +- Cypress is fast and performant. |
| 39 | +- Cypress supports many Angular features, including directives, pipes, and services. |
| 40 | +- Cypress can be used to test Angular components in isolation or in the context of a larger application. |
| 41 | + |
| 42 | +**Getting started with Cypress component testing** |
| 43 | + |
| 44 | +To get started with Cypress component testing, you will need to install Cypress and the Cypress Angular support package. You can do this by running the following commands in your terminal: |
| 45 | + |
| 46 | +```sh |
| 47 | +npm install cypress -D |
| 48 | +npm install @cypress/angular |
| 49 | +``` |
| 50 | + |
| 51 | +Once Cypress is installed, you can create a new test file. For example, you could create a file called `stepper.component.spec.ts`. This file will contain the tests for your stepper component. |
| 52 | + |
| 53 | +**Writing your first Angular component test** |
| 54 | + |
| 55 | +The following code snippet shows how to write a simple test for a stepper component: |
| 56 | + |
| 57 | +```ts |
| 58 | +import { ComponentFixture, TestBed } from '@angular/core/testing'; |
| 59 | +import { StepperComponent } from './stepper.component'; |
| 60 | + |
| 61 | +describe('StepperComponent', () => { |
| 62 | + let component: StepperComponent; |
| 63 | + let fixture: ComponentFixture<StepperComponent>; |
| 64 | + |
| 65 | + beforeEach(() => { |
| 66 | + TestBed.configureTestingModule({ |
| 67 | + declarations: [StepperComponent] |
| 68 | + }); |
| 69 | + |
| 70 | + fixture = TestBed.createComponent(StepperComponent); |
| 71 | + component = fixture.componentInstance; |
| 72 | + fixture.detectChanges(); |
| 73 | + }); |
| 74 | + |
| 75 | + it('should render the stepper component', () => { |
| 76 | + expect(component).toBeTruthy(); |
| 77 | + }); |
| 78 | +}); |
| 79 | +``` |
| 80 | + |
| 81 | +This test will check that the stepper component is created and that it is visible. |
| 82 | + |
| 83 | +**Advanced topics in Angular component testing** |
| 84 | + |
| 85 | +There are many advanced topics in Angular component testing. Some of these topics include: |
| 86 | + |
| 87 | +- Testing Angular components with data binding |
| 88 | +- Testing Angular components with RxJS |
| 89 | +- Testing Angular components with router |
| 90 | +- Testing Angular components with Angular Material |
| 91 | + |
| 92 | +If you are interested in learning more about these topics, I recommend checking out the Cypress documentation. |
| 93 | + |
| 94 | +## Conclusion |
| 95 | + |
| 96 | +Angular component testing is an important part of developing Angular applications. Cypress is a powerful tool for Angular component testing. It is easy to use, fast, and supports many Angular features. I hope this blog post has helped you get started with Angular component testing with Cypress. |
