Angular 9 + CLI (TypeScript) - How to stop generating .spec.ts test files

Issue

I know it's kind of a bad practice, but bear with me:

I'm using Angular-CLI, particularly ng g to generate all of my classes. However, I'm not interested in any *.spec.ts test files. I know that there are two flags (--inline-template, --inline-style) to handle inline CSS and HTML instead of separated files, and for spec the --spec flag is set to true by default.

So for each run, yes, I could do ng g c foo --it --is --spec=false.

But how do I disable the creation of test files globally? Is there any default setting for it?

Rashly, I did some stuff (that didn't work), like:

ng set spec=false --global

I also tried configuring my src/tsconfig.json by filling the exclude array:

"exclude": [
    "**/*.spec.ts"
]

Solution

For Angular 9 > (version 6 > below)

1) Copy snippet to the root of angular.json, (configures settings to all projects/globally).
2) Or copy snippet to the root of a specific project (projects.your-project-name) in angular.json (configures settings for a specific project).

"schematics": {
  "@schematics/angular:component": {
    "style": "scss",
    "skipTests": true
  },
  "@schematics/angular:class": {
    "skipTests": true
  },
  "@schematics/angular:directive": {
    "skipTests": true
  },
  "@schematics/angular:pipe": {
    "skipTests": true
  },
  "@schematics/angular:service": {
    "skipTests": true
  }
},

All configurable options per type of file Schematic Options:

"schematics": {
  "@schematics/angular:component": {
    "changeDetection": "Default",
    "entryComponent": false,
    "export": false,
    "flat": false,
    "inlineStyle": false,
    "inlineTemplate": false,
    "module": "",
    "prefix": "",
    "selector": "",
    "skipImport": false,
    "spec": true,
    "style": "css",
    "viewEncapsulation": "Emulated",
    "skipTests": "false"
  },
  "@schematics/angular:module": {
    "commonModule": true,
    "flat": false,
    "module": "",
    "routing": false,
    "routingScope": "Child"
  },
  "@schematics/angular:service": {
    "flat": true,
    "skipTests": true
  },
  "@schematics/angular:pipe": {
    "export": false,
    "flat": true,
    "module": "",
    "skipImport": false,
    "skipTests": true

  "@schematics/angular:directive": {
    "export": false,

Angular CLI configuration with Angular CLI

ERROR:

The ng set defaults.spec.component false command results in the error: get/set have been deprecated in favor of the config command.

ng set got changed to ng config.

Using the Angular CLI (config command usage):

The settings for generating specs, inline templates, inline styling etc. within angular.json are now persisted inside the schematics.@schematics/angular.<file-type>.<setting>.

Run ng config schematics.@schematics/angular.component.spec false to configure spec for components. This command adds the setting inside the schematics property within the angular.json file.
