It looks like if test are executed twice.

[jsanz1209]

Hello, does it happen to anyone that it seems as if the tests were executed twice?

I mean, I have 1289 tests in my project and in console it appears that 2578 were executed., (In the screenshot below I have taken the screenshot almost at the end of the execution, it shows 2551 of these) but when the final report is being generated, it appears the 1289 tests.

I have updated Angular (12.2.10) , Jest and Nx to their latest version.

My package.json is as follows:

The base jest.config.js (the one in the root) is as follows:

module.exports = { testMatch: ['/+(*.)+(spec|test).+(ts|js)?(x)'], transform: { '^.+\.(ts|js|html)$': 'ts-jest', }, resolver: '@nrwl/jest/plugins/resolver', moduleFileExtensions: ['ts', 'js', 'html'], coverageDirectory: '/coverage', reporters: ['default', 'jest-junit', ['jest-sonar', { outputDirectory: './', outputName: 'test-report.xml', reportedFilePath: 'absolute' }], ], setupFiles: [ '/test-setup.ts' ], coverageReporters: ["json", "lcov", "clover", "text", "text-summary", "cobertura"], collectCoverageFrom: [ "*/.ts", "!/node_modules/", "!/vessel.ts", "!/*.module.ts", "!/routes.ts", "!/paths.ts", "!*/.token.ts", "!/*.collection.ts", "!/*.enum.ts", "!*/.model.ts", "!/.mock.ts", "!/polyfills.ts", "!/main.ts", "!/index.ts", "!/help*.ts", "!/admin-help/", "!/*.environment.ts", "!*/environment.ts", "!/typings.d.ts" ], projects: [ '/libs/core', '/libs/menu-ui', '/libs/shared', '/apps/ioms-main', '/apps/auth', '/apps/side-menu', '/apps/dashboard', '/apps/messaging', '/apps/administration', '/apps/data-request', '/apps/vessels', '/apps/compliance-data' ] };

My jest-preset.js is the following:

const nxPreset = require('@nrwl/jest/preset');

nxPreset.transform = { '^.+\.(ts|js|html)$': 'jest-preset-angular' }; module.exports = { ...nxPreset };

the test-setup.ts that is in the root is the following: import 'jest-canvas-mock'; import '@frontend/core/mocks/libs/rxjs.mock';

console.warn = (message: string) => { if(!message.includes('Could not find Angular Material core theme. Most Material components may not work as expected. For more info refer to the theming guide: https://material.angular.io/guide/theming')) { console.warn(message); } };

the jest.config.js files of the different projects are as the following:

module.exports = { displayName: 'core', name: 'core', coverageDirectory: '../../coverage/libs/core', preset: '../../jest.preset.js', setupFiles: ['./../../test-setup.ts'], setupFilesAfterEnv: ['/src/test-setup.ts'], globals: { 'ts-jest': { tsconfig: '/tsconfig.spec.json', stringifyContentPathRegex: '\.(html|svg)$' }, }, snapshotSerializers: [ 'jest-preset-angular/build/serializers/no-ng-attributes', 'jest-preset-angular/build/serializers/ng-snapshot', 'jest-preset-angular/build/serializers/html-comment', ] };

What could be happening?

Thanks in advance.

Can you replicate this on the Nx Examples repo?

There are 32 tests there... if you put a for loop around a test suite, you should be able to emulate 1000 tests or so... I only see it count up to 1000 :confused: Could you provide a repo that would helps us reproduce this?

[jsanz1209]

Hi @FrozenPandaz! Thanks for your answer.

I can't share my repository due to confidencial issue, but I could replicate this on Nx Example Repo, but only adding another project, for example, currently the repo only have one angular project (product), I added another project (order), so in total I have 35 tests and I could watch almost 64 tests while jest was executing.

The command that I executed for replicate this was jest --coverage
