Using Jasmine with node

The Jasmine node package contains helper code for developing and running Jasmine tests for node-based projects.

Install

 

      

    		
  

  

    
      

        
      

      
You can install Jasmine using npm, locally in your project and globally to use the CLI tool.

    		
    
      

        
npm install jasmine

npm install -g jasmine

      

    		
  

  

    
      

        
      

      
Init a Project

    		
    
      

        

      

    		
  

  

    
      

        
      

      
Initialize a project for Jasmine by creating a spec directory and configuration json for you.

    		
    
      

        
jasmine init

      

    		
  

  

    
      

        
      

      
Generate examples

    		
    
      

        

      

    		
  

  

    
      

        
      

      
Generate example spec and source files

Configuration

    		
    
      

        

      

    		
  

  

    
      

        
      

      
Customize spec/support/jasmine.json to enumerate the source files and spec files you would like the
Jasmine runner to include. You may use dir glob strings.



spec_dir is used as a prefix for all spec_files and helpers.
Helpers are executed before specs.

    		
    
      

        
{
  "spec_dir": "spec",
  "spec_files": [
      "appSpec.js",
      "requests/**/*[sS]pec.js",
      "utils/**/*[sS]pec.js"
  ],
  "helpers": [
      "helpers/**/*.js"
  ]
}

      

    		
  

  

    
      

        
      

      
Running tests

    		
    
      

        

      

    		
  

  

    
      

        
      

      
Once you have set up your jasmine.json, you can start Jasmine by running jasmine from the root of your project.



Pass a relative path to a spec file to the jasmine command to only execute specs in a single file.

    		
    
      

        
jasmine

jasmine spec/appSpec.js

      

    		
  

  

    
      

        
      

      
CLI Options

    		
    
      

        

      

    		
  

  

    
      

        
      

      
JASMINE_CONFIG_PATH=
Specify a relative or absolute path to your configuration file. Can be used as an option or set as an environment variable.



----no-color
Turns off color in spec output

    		
    
      

        
JASMINE_CONFIG_PATH=spec/config/jasmine.json jasmine

jasmine JASMINE_CONFIG_PATH=spec/config/jasmine.json

jasmine --no-color

      

    		
  

  

    
      

        
      

      
Using the library

    		
    
      

        

      

    		
  

  

    
      

        
      

      
Jasmine can also be used as a library in your project.

    		
    
      

        
var Jasmine = require('jasmine');
var jasmine = new Jasmine();

      

    		
  

  

    
      

        
      

      
Load configuration from a file or from an object.

    		
    
      

        
jasmine.loadConfigFile('spec/support/jasmine.json');

jasmine.loadConfig({
  spec_dir: 'spec',
  spec_files: [
      'appSpec.js',
      'requests/**/*[sS]pec.js',
      'utils/**/*[sS]pec.js'
  ],
  helpers: [
      'helpers/**/*.js'
  ]
});

      

    		
  

  

    
      

        
      

      
Reporters

    		
    
      

        

      

    		
  

  

    
      

        
      

      
A ConsoleReporter is included if no other reporters are added. You can configure the default reporter with configureDefaultReporter. The default values are shown in the example.

    		
    
      

        
jasmine.configureDefaultReporter({
  onComplete: function(passed) {
      if(passed) {
          exit(0);
      }
      else {
          exit(1);
      }
  },
  timer: new this.jasmine.Timer(),
  print: function() {
      process.stdout.write(util.format.apply(this, arguments));
  },
  showColors: true,
  jasmineCorePath: this.jasmineCorePath
});

      

    		
  

  

    
      

        
      

      
You can add a custom reporter with addReporter. If you add a reporter through addReporter, the default ConsoleReporter will not be added.
Multiple reporters can be added.

    		
    
      

        
var CustomReporter = require('./myCustomReporter');
var customReporter = new CustomReporter();

jasmine.addReporter(customReporter);

      

    		
  

  

    
      

        
      

      
Run the tests

    		
    
      

        

      

    		
  

  

    
      

        
      

      
Calling execute will run the specs.

    		
    
      

        
jasmine.execute();

      

    		
  

  

    
      

        
      

      
execute can optionally be called with a list of spec file paths to execute relative to your project root.

    		
    
      

        
jasmine.execute(['fooSpec.js']);

      

    		
  

  

    
      

        
      

      
A simple example using the library


    		
    
      

        
var Jasmine = require('jasmine');
var jasmine = new Jasmine();

jasmine.loadConfigFile('spec/support/jasmine.json');
jasmine.configureDefaultReporter({
  showColors: false
});
jasmine.execute();
