Angular 7 with Cypress and Azure DevOps Build Pipeline

This is a follow-up post to my previous blog post that builds Angular on Azure DevOps. In this post I'm switching out the e2e tests for Cypress tests.

Cypress has a lot of features, but this is going to be the absolute quickest to get something working.

I have my base angular install, and I add the two below packages.

> npm install --save-dev start-server-and-test
> npm install cypress --save-dev

and then added these commands to scripts in package.json.

  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "cypress-open": "node_modules\\.bin\\cypress open",
    "cypress-run": "node_modules\\.bin\\cypress run --reporter junit --reporter-options mochaFile=junit-result.xml,toConsole=true",
    "e2e": "start-server-and-test start http-get://localhost:4200 cypress-run"

Run npm run cypress-open from the command line and Cypress will open and create some new files.

New Cypress

Delete all the created spec files and create a new one named `test.spec.js and add these contents:

/// <reference types="Cypress" />

context('Some tests', () => {
    beforeEach(() => {

    it('page loads', () => {


Notice that cy.visit('/') doesn't reference a full url. That's because there's a bit of configuration that has to be added to the existing cypress.json file:

    "baseUrl": "http://localhost:4200",
    "video": false

Run the command npm run e2e` and the Angular project will start up and then Cypress tests will run.

Test Cypress

The relevant Azure DevOps yaml is this.

  - task: Npm@1
    displayName: 'E2E Test Angular'
      command: custom
      customCommand: run e2e
      workingDir: src/angular7-cypress
  - task: PublishTestResults@2
    displayName: 'Publish Angular E2E test results'
    condition: succeededOrFailed()
      searchFolder: $(System.DefaultWorkingDirectory)/src/angular7-cypress/
      testRunTitle: Angular_E2E
      testResultsFormat: JUnit
      testResultsFiles: "**/junit-result.xml"

All tests should pass.
