can't load angular.js for unit test with karma, jasmine, phantomjs, and maven

Question

I'm trying to arrange my alphabet soup of angular, karma, jasmine, phantomjs, and maven. I'm doing this with a toy project for now, in preparation for integrating into a real project.

The following is my relevant list of files:

./pom.xml
./src/main/webapp/index.html
./src/main/webapp/js/blog.js
./src/test/webapp/js/blogSpec.js
./src/test/webapp/js/karma.conf.js
./src/test/webapp/js/libs/angular-mocks.js
./src/test/webapp/js/libs/angular.js

Here is my complete pom:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  <packaging>war</packaging>
  <build>
    <plugins>
      <plugin>
        <groupId>com.kelveden</groupId>
        <artifactId>maven-karma-plugin</artifactId>
        <version>1.5</version>
        <executions>
          <execution>
            <goals>
              <goal>start</goal>
            </goals>
          </execution>
        </executions>
        <configuration>
            <configFile>${basedir}/src/test/webapp/js/karma.conf.js</configFile>
            <browsers>PhantomJS</browsers>
            <reporters>dots</reporters>
            <colors>false</colors>
            <autoWatch>false</autoWatch>
        </configuration>
      </plugin>
    </plugins>
  </build>
  <dependencies>
    <dependency>

        <artifactId>maven-karma-plugin</artifactId>
        <version>1.5</version>
    </dependency>
  </dependencies>
</project>

And my "karma.conf.js" file:

module.exports = function(config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine'],
    files: [
      "../../../../src/test/webapp/js/libs/*.js",
      "../../../../src/main/webapp/js/*.js",
      "../../../../src/test/webapp/js/*.js"
    ],
    exclude: [],
    reporters: ['dots'],
    port: 9876,
    colors: false,
    logLevel: config.LOG_DEBUG,
    autoWatch: false,
    browsers: ['PhantomJS'],
    captureTimeout: 60000,
    singleRun: true
  });
};

The following is an excerpt from my "mvn install" output, starting at the Surefire execution:

[INFO] --- maven-surefire-plugin:2.10:test (default-test) @ angularjsexp ---

I have the following issues so far, some annoyances, some blockers: * It's weird that karma resolves file path references relative to where it found my conf file, I wish I could override that. * It appears that Surefire fires before Karma. Is it possible to integrate these? * My references to "angular" and other objects in my scripts are obviously failing. I don't understand how to resolve this.

Answer 1

Thanks to someone on the karma-users discussion group, I discovered that the files loaded from "files" have to be loaded in the correct order. For instance, instead of " ../../../../src/test/webapp/js/libs/*.js ", I need to specify " ../../../../src/test/webapp/js/libs/angular.js ", then " ../../../../src/test/webapp/js/libs/angular-mocks.js ".

I still have to figure out how to properly integrate Surefire, but I'll ask that separately.

Answer 2

I have been testing Angular with Karma and Jasmine and finally it works! My example is much simpler than yours, but maybe it can help you. I have an application in Angular in two files:

• controllers.js
• application.js

And the following files for Angular:

• angular.js
• angular-mocks.js
• angular-route.js

I have edited the karma.config.js manually and I have put files instead of routes because it works in a concrete order, so finally the ordered file list for Karma is:

// list of files / patterns to load in the browser
files: [
  'js/libs/angular.js',
  'js/libs/angular-mocks.js',
  'js/libs/angular-route.js',
  'js/controllers.js',
  'js/application.js',
  'spec/*.spec.js'
],

// list of files to exclude
exclude: [
  'karma.config.js'
],

My directory tree is:

• karma.config.js
• /js
  • application.js
  • controllers.js
  • /libs
    • angular.js
    • angular-mocks.js
    • angular-route.js
• /spec
  • application.spec.js

And I test Karma in the root folder with $ karma start karma.config.js .

Hope this helps
