Performing Load Testing in Salesforce using Selenium and TestNG

Parallel execution of browsers in Selenium with the help of TestNG and determining maximum operating capacity of custom code in Salesforce

When we build any custom solution in Salesforce, key is to write an efficient and meaningful Apex test classes for sure. However sometime we may need to test how custom application would behave in maximum operating capacity. Here, I am talking about Load Testing of custom applications built on top of platform. Recently I needed to push my code to its limit to know how many concurrent users can use it before hitting any governor limits. Quickly I realize that its time to call my friends Selenium and TestNG.

Before doing any extensive stress or load testing on Salesforce, we must need to contact Salesforce support and explain them what we are trying to achieve. More detail available in this official Salesforce blog post.

I have published some blog posts about Selenium in past as well however whats different this time ? I need to determine after how many simultaneous user interactions, I would hit Concurrent Apex Limit error as shown in below image.

Export or print code review feedback generated by Salesforce Lightning CLI

How to print or export code review feedback report generated by Salesforce Lightning CLI tool

Update : We can use this heroku app to scan Lightning component online and get code review feedback. Complete source code is available here. We don’t need to install Lightning CLI until its project compliance issue.

In this post, we discussed that how Lightning CLI can be used to get a code review information of custom Lightning component. However, code review is either printed or exported as a file in text or JSON format. Question is, how to get Lightning component code review feedback in HTML or PDF format ?

I tried various options available here however there were no way to export code review feedback generated by Lightning CLI. Output generated by Lightning CLI is not presentable to business executives or clients.

Finally, I came up with very simple Heroku application, which can be used to get Lightning CLI code review feedback in HTML or pdf format. We need to run below command to get CLI code review in JSON format. Continue reading “Export or print code review feedback generated by Salesforce Lightning CLI”

Continuous Integration (CI) in Salesforce using Team Foundation Server (TFS) – Video

Step by step guide to set up Continuous Integration (CI) for Salesforce using Team Foundation Server (TFS) with video tutorial

I have already written some Continuous Integration (CI) posts for Salesforce previously using different tools like Jenkins. In this blog post we will go through steps to use Microsoft Team Foundation Server (TFS) to set up Continuous Integration.

We can either use cloud based Team foundation Server (TFS) or locally installed on network. For ease, we would be using cloud based TFS for this blog post.

Step 1: Creating developer account on VisualStudio Online

Navigate to and choose Get Started for free in Visual Studio Team Services section. You may need to create a new Microsoft developer account, if you don’t have it already.

Step 2: Using TFS as source code repository

Once we are able to login to TFS, lets start by creating a code repository. That’s right, you don’t need separate Bitbucket or Github account to save your code/metadata unlike in Jenkins. So, our start with TFS is really good and impressive till this point 🙂 . Wizard to create new project is self explanatory and would look like below image

Dynamically remove XML content from metadata before Salesforce deployment using xmlTask – Video

Example – automatically remove listview before deployment

Many post about deployment using ANT has been posted on this blog like auto backup complete Salesforce instance daily, upload Salesforce data on FTP Server, auto generate package.xml, continuous integration and so on.

While implementing real Continuous integration in Salesforce, we need to perform various adjustments in metadata before deploying it to build server or production instance, many automated scripts (automation) are needed. If you need to change ANT scripts or metadata frequently, then it means continuous integration or deployment process in your Salesforce project is not yet fully matured.

There could be multiple situation where we don’t want some component to be deployed on production and example of one of them is List view Continue reading “Dynamically remove XML content from metadata before Salesforce deployment using xmlTask – Video”

Twitter’s Like button as Salesforce Lightning Component- pure CSS3 with Video

Building Lightning component checkbox to have Twitter’s Heart like animation without any image or JavaScript.

Twitter uses image sprite and JavaScript to produce Like button animation. We would be giving same effect to checkbox by using Lightning component. Combination of Checkbox, Label and Box property of CSS3 is used to give final result.

Lightning Component will contain only declaration of checkbox as shown below.


<aura:component >
<input id="toggle-heart" type="checkbox" />
<label for="toggle-heart">❤</label>

Note : In above source code, heart UTF icon is getting replaced by emoji code, so refer this screen to see exact code written for Lightning Component.

We have used Sassy CSS (SCSS) in this demo, as it would be little bit hard to write pure CSS with animation. Once SCSS is written, we can use this online tool to convert it to CSS. All these are explained and build live on my channel. Continue reading “Twitter’s Like button as Salesforce Lightning Component- pure CSS3 with Video”

Lightning component code review using CLI – Video

Video tutorial explaining how we can use Lightning CLI to identify possible issues and enhancements needed for Lightning Component and enabling it for Locker Service

Lightning CLI is code linting tool, which can be used to validate source code of Lightning components (Javascript files only). This tool is made specially keeping Locker Service in mind where we can validate if Lightnign component is breaking any contract while trying to access DOM element out of its own scope.

Lightning CLI is based on open source project ESLint. Below video demonstrates how we can install Lightning CLI and use it for existing Lightning Components. You can subscribe to my youtube channel to get latest update on Salesforce related videos.

Use below command to install heroku CLI plugin, assuming you already have heroku installed :

 heroku plugins:install salesforce-lightning-cli

Get code review comments on screen as a text

heroku lightning:lint .

Get code review comment on screen as a JSON

heroku lightning:lint . -j

Export code review comments in a file

heroku lightning:lint . > CodeReview.txt
heroku lightning:lint . -j > CodeReview.json

To export code review feedback generated by Salesforce Lightning CLI tool, refer this blog post.

Guide to setup Omni Channel in Salesforce with Video

Step by step guide to know about Omni Channel and how does it makes Call Centre Queue Manager’s life easier in Salesforce Service Cloud

We can route case or lead records to Queue on basis of assignment rules. Queue can also be set as an owner for custom object records. However, once record is assigned to queue, it needs manual intervention to assign it further to members in queue or queue member can assign to themselves. Queue members assigning to themselves, however may result into cherry picking. Some agents may resolve easier cases and some of them only gets time consuming or hard cases.

Omni-Channel offering from Service cloud is promising product and resolves this problem to some extend. It can automatically route records to agents in queue on basis of incoming case complexity and work load of agents.

Delete Components using Ant Migration tool – Video

This video tutorial shows that how we can delete components like Apex class, trigger from Salesforce using ANT migration tool.

I have posted multiple basic and advance articles about using ANT or ANT migration tool with Salesforce. Some of most visited articles are :

Going through multiple comments, I decided to create this 5 minute video tutorial to demonstrate, how we can use DestructiveChanges.xml in Ant migration tool to delete components.

As known already, we cannot simply delete components from Salesforce production using changeset. Apex classes, triggers etc cannot be deleted manually as well.

Responsive Datagrid component in Lightning – Basics

This blog post explains simple use case of Nested Lightning Component. It goes through example on how to interact and combine nested components to be used in parent Lightning component.

Please refer this post of latest version of responsive Datagrid Lightning Component.

This is a first blog post of a series, to develop advance lightning components and understand various features offered by Salesforce Lightning Platform. This post will explain why do we need nested components and how do they communicate.

At first, nested components looks like displaying something in child component and wrapped in parent component. However, to make most of nested components and designing efficient Lightning components, we should use nested component only to define set of rules. Unlike components in Visualforce, where we render some reusable output on page, Nested components in Lightning defines set of attributes to be used by parent component.

Hard to digest and imagine ? Please read on this post, you will understand concept soon. Continue reading “Responsive Datagrid component in Lightning – Basics”
