Web Atoms Unit Testing
Simple Unit testing framework for web atoms.
Dependencies
typescriptPlease make sure, decorator support is enabled for your tests.
Installation
npm install web-atoms-unitRunning with Node
Create a run-tests.js file
var fs = require("fs");
var vm = require("vm");
function loadScript(file){
var s = fs.readFileSync(file,'utf-8');
var script = new vm.Script(s, { filename: file });
script.runInThisContext();
}
// load web atoms mock
loadScript("./node_modules/web-atoms-unit/web-atoms-mock.js");
// load web atoms mvvm
loadScript("./node_modules/web-atoms-mvvm/dist/web-atoms-mvvm.js");
// load web atoms unit
loadScript("./node_modules/web-atoms-unit/index.js");
// load your tests..
// ideally all typescript files should be transpiled into
// one js file
loadScript("./tests/generated-test.js");
// .. so on.. you can write a script to load many files....
var p = WebAtoms.Unit.TestRunner.instance.run(process.argv[2]);
p.then(function(){
process.exit();
});
p.catch(function(error){
console.error(error);
process.abort();
});
// run all tests
node run-tests.js
// run tests by filtering categories provided by comma separated categories
node run-tests.js categories,categories
// run tests by filtering categories provided by regular expressions
