Jasmine having better modularity

Question

I am a newbie to jasmine, please correct me if I am asking a wrong question.

I am working on a legacy system which has a lot java script code. I would like to write some tests for the same. Initially I thought of using buster since it's in beta I didn't explored much about it. Meantime while searching I came across jasmine. Writing tests in jasmine was simple, maven plugin makes jasmine to be integrated with CI also we can get coverage report. So I felt to use jasmine.

In our current legacy systems there are several js, which need's a lot of refactoring . But to start off writing some test.I need some help. Let me narrate the problem I am facing

We have a lot of scripts having conflicting function names, and global variable's and so on. So specifying the jsSource in pom or jstestconf file is cumbersome, as I need to exclude few files, sometimes scripts which needs tests might have a conflicting function name. Also some scripts may be dependent on other's and so on.

Is there a way in jasmine the below mentioned scenario could be achieved.

Test1.js

• Include specific library, excluding common once
• Include the java script(Source1.js) source which needs to tested
• Then write the tests

Test2.js

• Include specific library, excluding common once
• Include the javascript source(Source2.js) which needs to be tested to tested
• Then write the tests

Something similar to junit's where we say include class which needs to be tested.

Doing some initial search I got to know by using requirejs I can achieve this. But I couldn't find any concrete example's.

I would need your opinion before proceeding further. Also is there any other testing framework which I use which have good integration with maven & eclipse and better modularity of tests.

I've been using Karma to run jasmine tests, and you can specify the files Karma includes via the karma.conf.js files property. So you could set up 2 different configurations for Test1.js and Test2.js. For example (assuming you have node_modules and your other files are under my-application-root:

for config 1:

module.exports = function(config){
  config.set({
  basePath : './',

  //files to load in the browser
  files : [
    'my-application-root/specific-library-1.js',
    'my-application-root/Source1.js',
    'my-application-root/test/Test1.js',
    'my-application-root/node_modules/**/*.js'
  ],

  exclude : [
    'my-application-root/common-lib.js',
    'my-application-root/specific-library-2.js',
  ],

.......

and for config 2:

module.exports = function(config){
  config.set({
  basePath : './',

  //files to load in the browser
  files : [
    'my-application-root/specific-library-2.js',
    'my-application-root/Source2.js',
    'my-application-root/test/Test2.js',
    'my-application-root/node_modules/**/*.js'
  ],

  exclude : [
    'my-application-root/common-lib.js',
    'my-application-root/specific-library-1.js',
  ],
