Mastering Application Development with Force.com

Overview of this book

Force.com is an extremely powerful, scalable, and secure cloud platform, delivering a complete technology stack, ranging from databases and security to workflow and the user interface. With salesforce.com's Force.com cloud platform, you can build any business application and run it on your servers. The book will help you enhance your skillset and develop complex applications using Force.com. It gets you started with a quick refresher of Force.com's development tools and methodologies, and moves to an in-depth discussion of triggers, bulkification, DML order of operations, and trigger frameworks. Next, you will learn to use batchable and schedulable interfaces to process massive amounts of information asynchronously. You will also be introduced to Salesforce Lightning and cover components—including backend (apex) controllers, frontend (JavaScript) controllers, events, and attributes—in detail. Moving on, the book will focus on testing various apex components: what to test, when to write the tests, and—most importantly—how to test. Next, you will develop a changeset and use it to migrate your code from one org to another, and learn what other tools are out there for deploying metadata. You will also use command-line tools to authenticate and access the Force.com Rest sObject API and the Bulk sObject API; additionally, you will write a custom Rest endpoint, and learn how to structure a project so that multiple developers can work independently of each other without causing metadata conflicts. Finally, you will take an in-depth look at the overarching best practices for architecture (structure) and engineering (code) applications on the Force.com platform.

Starting and stopping your tests


One of the unique features of the Salesforce1 platform is its governor limits. These limits are intended to keep you from writing inefficient code and, more importantly, ensure that no one org is using vast amounts of resources at the detriment of other org's. Having said that, they can often cause problems when writing tests. After all, if you're creating your own test data, and testing in bulk, you may very well run into the max DML or max query count limits. This is why Salesforce created the platform-unique startTest and stopTest methods. These methods do more than just delineating the portions of your test that exercise your code; they provide you with two invaluable services. First, calling startTest() will reset your governor limits and limit them to just the code between startTest() and stopTest(). This means that you are free to create your test data without the creation of that data causing you to hit a governor limit. Additionally, it means that...
