mocha test fails express REST API - node.js

Question

below is my Accounts.js Module.
var Accounts = function(){
return{
registerNewUser : function(req,res){
console.log(req.body);
var email = req.body.email;
var password = req.body.password;
if(email === undefined || password === undefined){
res.status(400).end('Required Fields Missing');
}
else{
email = email.trim();
password = password.trim();
console.log('lengths = ', email.length, ' password length = ', password.length);
if(email.length <= 0 || password.length <= 0){
res.status(400).end('Bad Request');
}
else{
res.status(200).end('ok');
}
}
}
}
}
module.exports = new Accounts();
Mocha UnitTests.js
var request = require('supertest');
var app = require('../express-app');
describe('Testing Route to Register New User', function(){
var server;
beforeEach(function(){
server = app.startServer();
});
afterEach(function(done){
server.close();
done();
});
it('Missing required fields test', function(done){
request(app).post('/register',{
}).expect(400).end(done);
}) ;
it('Empty field test',function(done){
request(app).post('/register',{
email:"",
password:" "
}).expect(400).end(done);
});
it('Should accept the correct email and password',function(done){
request(app).post('/register',{
email:"email",
password:"alskdjfs"
}).expect(200).end(done);
});
});
Mocha Output:
Testing Route to Register New User
API Server listening on port 3000
{}
✓ Missing required fields test
API Server listening on port 3000
{}
✓ Empty field test
API Server listening on port 3000

Error: expected 200 "OK", got 400 "Bad Request"

I have tested the above route using curl cli and it works as expected , similarly it works as expected from the browser form post , i do not know why mocha fails it ?
Can some one please throw light where i am doing wrong to fix this issue.

You are probably sending the data in a wrong way. Try this
it('Should accept the correct email and password',function(done){
var data = {
email:"email",
password:"alskdjfs"
};
request(app).post('/register').send(data).expect(200).end(done);
});
