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

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"
]

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).

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

Solution 2:^[2]

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
    }
  },

Solution 3:^[3]

You can run this command to disable spec file generation for a specific type of file:

ng set defaults.spec.FILETYPE false

For example:

ng set defaults.spec.component false // Won't generate spec files for .component files

Alternately you can just disable all spec file generation from the angular-cli.json file.

{
  ...
  "defaults": {
    "spec": {
      "class": false,
      "component": false,
      "directive": false,
      "module": false,
      "pipe": false,
      "service": false
    }
  }
}

Solution 4:^[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
    }
  }

Solution 5:^[5]

you can add --skipTests=true|false if true it wont generate any spec.ts

example : ng g component componentName --skipTests=true

this line wont generate any spec.ts files

EDIT:

Note: As of angular 7 this command doesn't work, even though this command is mentioned on the official website of angular. Here: https://angular.io/cli/generate#component

Solution 6:^[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"
}

Additional Reference => Angular Docs for CLI Generate Command

Solution 7:^[7]

you can add --spec=false

example

ng g c home --spec=false

log will be

CREATE src/app/home/home.component.scss (0 bytes)
CREATE src/app/home/home.component.html (23 bytes)
CREATE src/app/home/home.component.ts (262 bytes)
UPDATE src/app/app.module.ts (467 bytes)

Solution 8:^[8]

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

Solution 9:^[9]

"@schematics/angular:component": {"style": "scss","skipTests": true}

Just add "skipTests":true to your angular.json file and you'll solve the problem

Solution 10:^[10]

you can try --skip-tests when you creating your app like below.

ng new yourProjectName --skip-tests

Solution 11:^[11]

Add Following code on Angular.json

"schematics": {
    "@schematics/angular": {
      "component": {
        "spec": false
      }
    }
  }

Solution 12:^[12]

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

Solution 13:^[13]

Just do this and you should be fine:

ng generate component newFile --skip-tests

Solution 14:^[14]

you can add --skipTests=true to stop generating spec file

Example:

ng g s core/services/auth/auth-guard --skipTests=true

log will be

CREATE src/app/core/services/auth/auth-guard.service.ts (138 bytes)
