webix - Cannot run multiple karma tests using suave server -

-

when run below tests individually (by commenting out) each test passes. however, when run tests xmlhttprequest uncaught exception. suave test server receives requests , logging shows no errors or problems:

var home_url = "http://localhost:3000/request";  it("should echo test request response", function (done) {     var test = { act: 'test1', qry: {} };      var promise = webix.ajax().post(home_url, json.stringify(test));      console.log('test1');     promise.then(function (resp) {         expect(resp.json().succ).to.be(true);         done();     }).fail(function (err) {         done();         throw(err);     });  });   it("should echo test request response 2", function (done) {     var test = { act: 'test2', qry: {} };      var promise = webix.ajax().post(home_url, json.stringify(test));      console.log('test2');     promise.then(function (resp) {         expect(resp.json().succ).to.be(true);         done();     }).fail(function (err) {         console.log('echo test error', app.util.inspect(promise));         done();         throw(err);     });  });

any ideas problem or how debug these tests?

to run code (git node , npm have installed):

git clone http://github.com/halcwb/genunitapp.git cd genunitapp git checkout failingserver scripts/run.sh

open second terminal

./build.sh clienttests

when down vote please explain, can improve question.

for running this, can nest ajax calls in before function , later on use promises (webix.ajax returns promise) in tests like:

var home_url = "http://localhost:3000/request"; var test1, test2;  before(function () {     var req = { act: 'test1', qry: {}};      test1 = webix.ajax().post(home_url, json.stringify(req));     req.act = "test2";     test2 = webix.ajax().post(home_url, json.stringify(req)); });  it("should echo test request response", function (done) {     var promise = test1;      promise.then(function (resp) {         expect(resp.json().succ).to.be(true);         done();     }).fail(function (err) {         done();         throw(err);     });  });   it("should echo test request response 2", function (done) {     var promise = test2;      promise.then(function (resp) {         expect(resp.json().succ).to.be(true);         done();     }).fail(function (err) {         done();         throw(err);     });  });

please explain when down vote, try learn.

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
