Most of us have experienced how important the Unit test cases are for our code base. I feel the other thing that is equally important, is the speed at which we can write the unit test cases. In Unit Testing, initializing different objects in setup of the test case (e.g., while testing a method which queries the database) can become a...
In my current project, we were required to implement Instance Based Security. The idea was to find a clean solution separate from the main business logic of the application. We took a clue from the Spring Security Plugin to use the Annotations to do our job. All we wanted to do was to develop annotations for actions, which could help to...
I have been working on grails for quite some time now. As a beginner, I had doubts about where to place the business logic in grails. Seeing the CRUD, one can easily be misled into putting most of the code in the actions, but as the code base goes bigger, it becomes difficult to manage those actions. Coming from the java background, with...
A few days back I had chance to work on a googleApp using GORM-JPA plugin,version (0.7.1). I came across a few problems which are as given below. Consider the domain : Country -> has many States. At first it appeared that the one to many relationships are to be managed using annotations like : Country { @OneToMany(mappedBy...
Ques: How is unit testing different from integration testing ? Ans: Integration tests need to bring up the whole grails environment.They talk to the database. All the dynamic GORM methods and properties are available here. Unit testing are small focused, fast loading tests that do not load supporting components. Ques: How can I unit...
Hi all, Here I am giving a brief introduction about unit testing of services in grails. I will explain it with the help of a simple example. We have a domain class named: Item Two services : UtilService and ItemService Code of UtilService.groovy // class UtilService code class UtilService { boolean transactional =...
Recently, in my project I had to implement search functionality. I used grails createCriteria to implement it.Now I needed to apply the sorting on the result returned. My domain was something like this : class MyEntity { OrganizationName orgName PersonName personName static constraints = { ...
If you want to keep track of the errors and exceptions on the view, after making an ajax call, then this might be something of your interest : jQuery().ready(function() { jQuery.ajaxSetup({ error: function(x, e) { if (x.status == 0) { alert('You are offline!!\n Please Check Your Network.'); } else if...
Implementing search functionality on the keyup event using ajax has one pitfall. It can bombard our server with unnecessary ajax calls. So it becomes imperative for us to introduce some delay between the ajax calls. One way to implement it will be to make an ajax call after some delay(say 500 ms) after the first character has been typed...
