Snapshot based unit testing for UI

akshaymhetre commented 5 years ago

Referred following doc to integrate Jest with angular : https://medium.com/@nerdic.coder/how-to-use-jest-unit-tests-with-angular-87509b500158

Apart from this, was getting TS:2339 : property 'toMatchSnapshot' does not exist on type Matchers<ComponentFixture>

Resolved this by adding globals diagnosis configuration (also added options which were default for jest-preset-angular)

"jest": { "preset": "jest-preset-angular", "setupFilesAfterEnv": [ "/src/setupJest.ts" ], "globals": { "ts-jest": { "tsConfig": "/src/tsconfig.spec.json", // default for jest-preset-angular "stringifyContentPathRegex": "\.html$", // default for jest-preset-angular "astTransformers": ["node_modules/jest-preset-angular/InlineHtmlStripStylesTransformer"], // default for jest-preset-angular "diagnostics": { "ignoreCodes": ["6059", "18002", "18003", "TS2339"] //apart from TS2339 all were default for jest-preset-angular } } } },
