I am using Jest to test an angular app and it is taking a really long time for simple tests to run and I can not seem to figure out why.
My Jest setup in package.json
:
"jest": {
"modulePaths": [
"<rootDir>/src",
"<rootDir>/node_modules"
],
"testPathIgnorePatterns": [
".git/.*",
"node_modules/.*"
],
"transformIgnorePatterns": [
"node_modules/.*",
".*\\.js"
],
"setupTestFrameworkScriptFile": "<rootDir>/src/setupJest.js",
"preset": "jest-preset-angular",
"testEnvironment": "jsdom",
"testRegex": "src/app/.*\\.spec\\.ts$",
"moduleFileExtensions": [
"ts",
"js",
"json"
],
"verbose": true,
"cacheDirectory": ".jest-cache",
"coveragePathIgnorePatterns": [
".*\\.(shim\\.ngstyle|ngfactory)\\.ts"
],
"globals": {
"ts-jest": {
"tsConfigFile": "./tsconfig.json"
},
"__TRANSFORM_HTML__": true
}
}
My Jest setup file:
'use strict';
require('core-js/es6/reflect');
require('core-js/es7/reflect');
require('zone.js');
require('zone.js/dist/proxy.js');
require('zone.js/dist/sync-test');
require('zone.js/dist/async-test');
require('zone.js/dist/fake-async-test');
require('jest-zone-patch');
const getTestBed = require('@angular/core/testing').getTestBed;
const BrowserDynamicTestingModule = require('@angular/platform-browser-dynamic/testing').BrowserDynamicTestingModule;
const platformBrowserDynamicTesting = require('@angular/platform-browser-dynamic/testing') .platformBrowserDynamicTesting;
getTestBed().initTestEnvironment(
BrowserDynamicTestingModule,
platformBrowserDynamicTesting()
);
Here is my simple test:
fdescribe('RichTextEditorComponent', () => {
it('should be fast', () => {
expect(true).toBeTruthy();
});
});
Does anyone have any idea as to why this is taking 9+ seconds?
from Jest - Simple tests are slow
