When in the terminal application I move to the /test/ folder and after running buster server and opening port 1111 in my browsers of choice (or in this case just one browser FF 10.0.2) I then open a new terminal tab and execute buster test --reporter specification but the terminal just hangs there doing nothing (where originally it would run the example-test.js test case and show what failed/succeeded).
Can you advise if I’ve missed something really obvious? I’m using the latest busterjs version (uninstalled and re-installed via NPM)
// Create a new assertion
buster.assertions.add('myIsArray', {
assert: function (obj) {
return Object.prototype.toString.call(obj).slice(8, -1) === 'Array';
}
});
// Typically, you have one test case per file
buster.testCase('My test module', {
// Can't have empty setUp/tearDown methods, but I leave them here to remember the syntax
setUp: function(){
this.clock = this.useFakeTimers(); // needed for async tests - modifies setTimeout/Interval to be synchronous (see: http://sinonjs.org/docs/#clock)
},
tearDown: function(){
this.clock.restore(); // put back the original asynchronous versions of setTimeout/Interval
},
// Two forward slashes at the start of a test case's name indicates that it should be ignored but shown in the results as 'deferred'
'//A test that I want to comment out for a while but not hide from the test results': function(){
var num = 123;
assert.match(num, 123);
},
'an async test': function(){
var num;
window.setTimeout(function(){
num = 123;
}, 10000);
this.clock.tick(10000);
assert.match(num, 123);
},
// Test case
'A bad test (as it tests random stuff when it should test specific functionality)': function(){
