Tests usually require resources to be loaded, such as jquery and Angular. One can load these as files, but some apps don't keep local copies, and instead download scripts from CDNs, etc.
This preprocessor lets you load your project's HTML files, from which the files denoted by the src field in the <script> files are downloaded and included in the test suites.
Pros:
- You do not need to manage local copies of resources using, e.g. bower
- Your project's html files are used, meaning you are guaranteed that there is consistency between test and live resources
Cons:
- Tests require Internet connectivity
- Downloads on each test iteration
$ npm install karma-preprocessor-pullscripts
First, include html files in the files section of your karma.conf.js. These will be processed in order.
files: [
'./path/to/file1.html',
'./path/to/file2.html',Add pullscripts to your preprocessor list:
preprocessors: {
'./path/to/*.html': 'pullscripts',
},All scripts are processed in order of appearance in the HTML files. For example if jquery is included before angular, then the jquery script will be downloaded and included before the angular script. If you have multiple html files with different scripts included, you might need to ensure the load order (order in files array) is consistent.
