  • We are going to start the day by talking about unit testing, and then in a bit SOQL. Because these are aspects of the platform which are really a dialtone, something we should be constantly evolving with.And yes, that’s a real bug. The first real bug.So if our new fictional job is to enhance this existing Warehouse application, how we write our unit tests are going to be very important.
  • So let’s talk about what some of your best practices are? Or if you’re brave, some of your worst?OK, let’s actually look at some really bad examples.
  • So to recap – Unit Tests should prove out not just code, but use cases. You should try to cover as much of your code as possible. And when should you test?

  • Indexed fields are fields tracked specifically by the database, and hence can lend to greater performance when your queries use them.
  • Apex can automatically create Maps from any SOQL result, and you can use that feature to either easily loop through the results or even to easily track the result in the map. For instance, the example here on the bottom would make it possible to find a specific contact in the result with one call from the map.
  • It’s also good to remember that you can pull children from the parent in one SOQL call. Let’s take a look at that in the Dev Console.SELECT Name, (SELECT Merchandise__r.Name from Line_Items__r) from Invoice__c LIMIT 5
  • You can also assign the SOQL result directly to a list, and then loop through that array. This allows you to quickly bulkify your code by generating loops and then performing any necessary DML when those loops are done.
  • One feature added recently to SOQL was the ability to use a readOnly annotation or flag to declare the results unusable in DML, but greatly expanding the number of results that can be handles. For instance, this visualforce page would normally only be able to handle an array of 1,000, but with readOnly that limit is relaxed to 10,000.
  • Some of the fields in the database are polymorphic, but until a few releases ago – SOQL didn’t really recognize that fact. Now that it does, you can cue specific results from those fields based on their Sobject type. Here’s an example in the Dev Console.SELECT Subject, TYPEOF What WHEN Account THEN Phone, NumberOfEmployees WHEN Opportunity THEN Amount, CloseDate ENDFROM Event
  • OFFSET allows you to create paginated results easily. The query on the left would give us the first 10 results, and the query on the right would give us the next 10. To see that in the Dev Console:SELECT NAME from Merchandise__c LIMIT 5 OFFSET 0SELECT NAME from Merchandise__c LIMIT 5 OFFSET 10(Or use Contact depending on the org)Now one key limit on OFFSET is that the maximum offset is 2000, so you’ll need to be paginating through a recordset smaller than that.
  • Aggregate searches allow a developer to do powerful mathematical searches against the database. In the example on the top here, you’ll get a count of merchandise by name for a specific invoice. Think of it like a highly customizable rollup field.The example on the bottom takes that same search, but shows you how it is split up. We’re summarizing an integer field, getting a child name field and then grouping it by that field. Here’s another example, where we can see how much a line item is worth by merchandise:SELECT SUM(Quantity__c) quantity, Merchandise__r.Name name from Line_Item__c Group By Merchandise__r.Name
  • The platform now supports geolocation. In order to do a dynamic search, like above, you’ll need to construct the string and then use a dynamic query. Using these queries, you could easily gather data based on physical location, for instance if you wanted to find the contact closest to where you parked.Here’s an example in the dev console:SELECT Name FROM Account WHERE DISTANCE(Location__c, GEOLOCATION(37.7945391,-122.3947166), 'mi') < 1
  • So SOSL isn’t exactly new – we’ve had in the system for some time. But if you are trying to search across different Sobject types, nothing beats it. Here we can find Tim even if he is a contact or account. Let’s look at an example in the Dev Console:FIND {Tim} IN Name Fields RETURNING lead(id, name), contact(id, name, LastModifiedDate), account(id, name, LastModifiedDate), user(id, name, LastModifiedDate) LIMIT 5

  • Controller testing should also include page reference asserts if you are moving from page to page
  • We’re used to thinking about Visualforce as a component based library, and that let’s us create HTML based interfaces very quickly and easily by binding those components to data. But what about using those components to mix and match Visualforce across your instance?
  • For instance, you can use Visualforce to create very custom dashboards, and then put those on your homepage. Here’s an example I’ve got with the Warehouse app, which is showing recently created Invoices:( /home/home.jsp )Now if I click into one of those Invoices, we’re also seeing visualforce.
  • Because, and this is probably one of the more common use cases for Visualforce, anything with a Standard Controller can be used in place of the standard list, view, edit style pages. On this page, I’m still displaying the page layout via the detail component, but we wanted to be able to leverage a new footer across different detail pages(show WarehouseDetail
  • And we’re keeping that new detail consistent by using a template. We can define our inserts, and then define our content. This allows us to maintain a lot of different look and feels across different object types, but controlling the parts that will the same in one place.
  • And of course, as we customize that layout, we can create custom components which can take incoming attributes and then render what we need. For instance, in my footer I am using a visualization jQuery plugin called isotope, which allows us to view the line items in a very different way than the related list. You’ll see more about jQuery later.
  • And of course, if I want that Visualforce in the middle of my layout, I can use a StandardController to embed that right into it. In fact, in this layout – this section is not being generated here on Salesforce.
  • It’s actually using Canvas, which allows me to easily put third part applications into Salesforce in a secure manner.
  • For instance, maybe I have a large internal intranet applications. I don’t want to port all that functionality into Salesforce, but I do want to be able to integrate this one interface.

  • Apex controllers are probably the most common use case for the language, but triggers merit a second place.
  • And with all of those potentials triggers in your system, they can easily get out of hand. There are a few best practices people have found to make them more maintainable.First, consider having only one trigger per object. Within the trigger class itself, break out every possible event, before and after, and start putting system.debugs around them. At the very least, this will make it very easy to track down in debug logs where the logic is getting fired.Second, consider handing off the actual logic to delegate classes. Send them the current scope of the trigger and let them sort it out. This will neatly divide the functionality that your trigger is trying to accomplish.
  • A delegate also gives you more breathing room. Look at all the variables we are using to properly track what this delegate wants to do – if you started stacking all the logic into the trigger itself, this will start to get unruly really fast. Don’t let your triggers become a battleground, they should be more like highways.
  • Another trick is using static variables in another class to track progress in your trigger. Changes to these flags will be visible for the span of the trigger context. So if, for instance, another process kicks off your trigger logic a second time, and you don’t want it to – you could swap the first flag here to true, and then not execute any logic if that flag is true.
  • And remember one of the more powerful uses of triggers is in association with Chatter. Let’s take a look at a labs app, Chatter Blacklist, which illustrates this very well.
