Question

See my test code using mocha + tamejs:

test/t.tjs

require('should');

function inc(n, callback) {
  setTimeout(function() {
    console.log('### inc: ' + n);
    callback(n+1);
  }, 1000);
};

describe('test', function(){
  it('show ok with tamejs', function(){
     console.log('### testing ...');
     var result;
     await { inc(1, defer(result)); }
     console.log('result: ' + result);
     result.should.equal(123456); // won't pass
  });
});

Compile it to t.js:

tamejs -o test/t.js test/t.tjs

Run mocha

mocha

Result:

### testing ...
.

✔ 1 test complete (1ms)    

It seems the inc method has never been invoked.

The problem is I didn’t use mocha correctly.

It should be wrote as:

describe('test', function(){
  it('show ok with tamejs', function(done){
     console.log('### testing ...');
     var result;
     await { inc(1, defer(result)); }
     console.log('result: ' + result);
     result.should.equal(123456); // won't pass
     done();
  });
});

Please notice the done, it used in mocha to determine if a asynchronous invocation has finished or not. Without it, mocha won’t wait for the asynchronous invocation.
