I have an angular 8, that uses karma/jasmine to run some unit tests. I can run tests by executing the following command ng test
but I'm getting the following error:
ERROR in ./src/polyfills.ts Module not found: Error: Can't resolve 'zone.js/dist/zone' in 'C:\PrjNET\Elevation3\FW\4.00\Project\Framework\Development\Client\ElevationJS\shell\src' resolve 'zone.js/dist/zone' in 'C:\PrjNET\Elevation3\FW\4.00\Project\Framework\Development\Client\ElevationJS\shell\src'
Any one know how to solve it?
I found out that my test configurations on tsconfig.spec.json
were wrong. So I change from this:
{
"extends": "./tsconfig.es5.json",
"compilerOptions": {
"outDir": "../out-tsc/spec",
"module": "commonjs",
"target": "es6",
"baseUrl": "",
"types": [
"jest",
"node"
]
},
"files": [
"test.ts",
"polyfills.ts"
],
"include": [
"**/*.spec.ts",
"**/*.d.ts"
]
}
to this:
{
"extends": "./tsconfig.es5.json",
"compilerOptions": {
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"outDir": "../out-tsc/spec",
"module": "commonjs",
"types": [
"jasmine",
"node"
]
},
"files": [
"test.ts",
"polyfills.ts"
],
"include": [
"**/*.spec.ts",
"**/*.d.ts"
]
}
And the error disapeared!
