A few years ago programming on the Salesforce platform primarily involved two languages, Visualforce and Apex. It is MVC (Model View Controller) based and easier to adapt to and start developing your first apps.
However, with the drastic changes to web development over the past few years the focus has moved towards building fast, scalable client based applications with minimal server calls to make the application easier and fast to use.
This lead to developing on the Salesforce platform using Lightning components. This post tries to simplify without going into details the different terms you come across once you get started with Lightning development.
What are Lightning Components ?
You program and develop small components that interact with each other on the salesforce platform. These components can be developed using two programming models.
Aura Components
Lightning Web Components
Aura is a much simpler framework with a major focus on plain javascript.
Lightning web components (LWC) is a much powerful framework with a lot more capabilities than the Aura framework. LWC is comparable to much popular frameworks including Angular, React etc.
LWC is officially recommended for new development, though Aura and LWC can co-exist and work along.
What is the Lightning Design System ?
The lightningdesignsystem.com is a pure CSS based framework that you could use for developing web pages that look and feel like Salesforce Lightning Experience UI. It has extensive support for grids, layouts, input and output elements that are ready to use.
Create an object with API name AutomatedTestingQueue__c
Create a field on this object of type TEST(40) with API name AsyncId__c
STEP 2:
Create the apex classes below.
Modify the SOQL query to pick test classes to execute. The query in this sample just picks any class with the name TEST in it.
Also update your email address to receive the results.
STEP 3:
Schedule the apex class 'AutomatedTestJobQueuer'. This will run the apex tests.
STEP 4:
Schedule the apex class 'AutomatedTestingJob'. This will send the email. Make sure you have enough gap between these two jobs to allow all tests to run. Sample here is one hour, you might want to increase this if you have many apex tests.
In this article we will look at implementing a simple lightning component that displays a list of contacts in a table. We will add a simple client side search box which searches all columns in the table.
