Cannot run multiple karma tests using suave server - karma-runner

Question

When I run the below tests individually (by commenting out) then each test passes. However, when I run all tests then I get an XmlHttpRequest uncaught exception. The suave test server receives the requests and the logging shows no errors or problems:
var HOME_URL = "http://localhost:3000/request";
it("should echo the test request with 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 the test request with 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 what the problem could be or how to debug these tests?
To run the code yourself (git node and npm have to be installed):
git clone http://github.com/halcwb/GenUnitApp.git
cd GenUnitApp
git checkout failingServer
scripts/run.sh
Open second terminal
./build.sh clienttests

For anyone running into this, you can nest the ajax calls in a before function and later on use the promises (webix.ajax returns a promise) in your 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 the test request with 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 the test request with 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);
});
});
