Angular 6 + CLI (TypeScript) - How to stop generating .spec.ts test files

Question

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

Answer 1

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"

    "flat": false,
    "module": "",
    "routing": false,
    "routingScope": "Child"
  },

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.

How to do X in Angular CLI v6

Answer 2

For angular 8+:

Option "spec" is deprecated: Use "skipTests" instead, so if you want to create a new component use:

ng g c my-new-component --skipTests=true

Answer 3

If you're using v6 and need to edit your angular.json

You can edit the schematics for your project.

"schematics": {
    "@schematics/angular:component": {
      "styleext": "scss",
      "spec": false
    },
    "@schematics/angular:class": {
      "spec": false
    },
    "@schematics/angular:directive": {
      "spec": false
    },
    "@schematics/angular:guard": {
      "spec": false
    },
    "@schematics/angular:module": {
      "spec": false
    },
    "@schematics/angular:pipe": {
      "spec": false
    },
    "@schematics/angular:service": {
      "spec": false
    }
  },

Answer 4

Just to update Sabbir Rahman's answer:

In version 1.0.2 of the CLI you will have to set the spec file to false for each individual type. An example is included below:

"defaults": {
    "styleExt": "scss",
    "component": {
      "spec": false
    },
    "service": {
      "spec": false
    },
    "directive": {
      "spec": false
    },
    "class": {
      "spec": false // Set to false by default
    },
    "module": {
      "spec": false // Set to false by default
    },
    "pipe": {
      "spec": false
    }
  }

Answer 5

Just Run this command: ng config schematics.@schematics/angular.component.spec false

Answer 6

For Angular 9+:

The Angular.json config has changed slightly which is causing previous configuration schemas to change, per this GitHub issue on Angular/CLI.

Adapted from @sacgrover's comment along with my own:

Old way

"@schematics/angular:component": {
    // true => DO generate spec files, false => DON'T generate them
    "spec": true,
    "styleext": "scss"
}

New way:

"@schematics/angular:component": {
    // true => DON'T generate spec files, false => DO generate them
    "skipTests": true,
    "style": "scss"
}
