Preprocessor for converting .json files into .js files and making them accessible from karma test environment
{
"devDependencies": {
"karma": "~0.12.1",
"karma-json-fixtures-preprocessor": "0.0.0"
}
}// karma.conf.js
module.exports = function(config) {
config.set({
preprocessors: {
'./fixtures/**/*.json': ['json_fixtures']
},
files: [
'./fixtures/**/*.json'
],
jsonFixturesPreprocessor: {
// strip this from the file path \ fixture name
stripPrefix: 'test/fixtures',
// strip this to the file path \ fixture name
prependPrefix: 'mock/',
// change the global fixtures variable name
variableName: '__mocks__'
}
});
};Preprocessor requires .json files and converts them into .js files by storing json data as javascript objects under __fixtures__ namespace.
the following file:
./fixtures/test.json
{
"a": "test"
}will be accessible in your test environment:
var fixture = window.__fixtures__['fixtures/test'];
fixture["a"] // => 'test'
