I’ve been fortunate to have worked as a consultant Salesforce architect for the last decade, during this time I’ve encountered an interesting variety of approaches to Agile in the Salesforce space – most of which fitting with the hybrid model unfortunately – what has been noticeably absent is the application of agile engineering practices. Test […]
A quick video post providing a demonstration of the interactive Apex Debugger. The context of the demonstration is an ISV partner debugging a packaged code issue in a subscriber (customer) org.
A basic understanding of the selective query concept is fundamental to scalability on the Salesforce platform. Non-selective queries have a significant performance impact on List Views, Reports and SOQL and can often result in Apex Trigger runtime exceptions as below – as the data volume increases over time. [code language=”java”] System.QueryException Cause: null Message: Non-selective […]
As I’ve previously stated the combination of Process Builder and Apex Actions is incredibly powerful. This short post adds the answer to a frequently asked question; how many times is the InvocableMethod called when records are modified in bulk? To answer this with an example. With default batch settings (200 records) and 201 modified records […]
A technical best practice in the Salesforce domain is to employ Apex code predominantly as an enabler for the declarative platform capabilities. This light-touch approach is simple in concept; the minimum amount of Apex code necessary is introduced to enable non-technical build features to solution the functional requirement. In the majority case this works very […]
This video post provides a technical overview of the Platform Cache feature added in the Winter ’16 release.
This post provides some general best practices in regard to Apex Unit Tests. This isn’t a definitive list by any means, as such I’ll update the content over time. Top 10 Best Practices (in no order) 1. TDD. Follow Test Driven Development practice wherever possible. There is no excuse for writing unit tests after the […]
Challenge – outside of the ISV development model there is no concept of an application namespace that can be used to group the technical components related to a single logical application. To mitigate this issue, and to provide a means to isolate application-specific components, naming schemes such as application specific prefixes are commonplace. Risk – […]
Custom Apex Triggers execute on standard CRM objects (Account, Contact, Lead etc.) and custom objects in response to all data modifications applied via the Salesforce web application, API transactions and custom Apex script. As such it is imperative that trigger code adheres to patterns that promote performance and maintainability, guards against recursive behaviour and most […]
A quick post to outline an informal convention for the definition of a Visualforce controller class, key maintainability characteristics being predictable structure, readability and prominent revision history. All developers have a subjective preference in this regard, however consistency is key, particularly in the Salesforce context where multiple developers/consultancies contribute to a codebase over its lifetime.
