These 6 Expert Tips Will Make Your Salesforce Testing Easier In 2020
Salesforce Testing is not an easy task. Because salesforce includes many classes, one which you don’t have control over. You can’t customize those classes. It is very difficult to find the failed areas. Whenever something got stuck, it would be a worrying hunt.
This hunt is to know whether you have clashed with in-built CSS or failed to include classes properly. Debugging itself is a complex job. I hope many of you won’t enjoy this process, right? But the good thing is, salesforce testing can be easy if you can follow some best practices.
You can incorporate good strategies, good tools and can save your time and effort. It will be helpful, especially in repetitive testing.
Expert Tips for Best Salesforce Testing Practices
APEX, a high-level development language from the force.com platform is very handy. It offers the best in-built features to write and run your code and test cases.
I am not discussing general things like good code structure and using comments.
1. Code Portability
It is one of the most important and foremost requirements in salesforce testing. Many professionals will agree with this. Your code can depend on external data, but only for validation of the username, data and more. But too much dependency on your code on external data will break the functionality.
The functionality of the code gets disturbed. When you move the code from development to the execution environment, chances increase. Your code should be smart to deal with null data. To avoid all these issues, you can make use of related URLs and SOQL for data records.
When testing your code in a sandbox, you can test for use-cases, where there is no data. If your code passes this test, then there is no stopping, it will pass in all environments.
2. Code Coverage
There is a standard Salesforce directive for the testing purpose. According to this directive, all the unit test cases should cover 75% of the code. This 75% excludes test methods and classes. Upon meeting this criterion, the salesforce allows you to deploy the apex code.
But you should not rely on these standards itself. You should look for 100% code coverage, which is the best practice. You can use case centric for the coverage. Your aim must cover all the use cases in the tests.
You should test for all positive and negative use cases if data are present or not. You must expertise in analyzing what are all the things that may affect. Mainly, you must ready for unanticipated things and work out it with best practices.
3. Writing Test Cases in Controllers and Classes
There are some best and standard salesforce practices that you should follow. This one includes creating separate files for controllers and classes.
This process will help your code to be easier, organized, portable, and mainly reusable. It is easy to create both controlled and class files. If you can include test code in controller and class files, then you can achieve portability.
The major use of this process is that you can’t miss the test code when you are moving from sandbox to production.
4. Assert based testing
There are some specific classes in Apex to check conditions. The classes like system.assert() are the best functionality that checks conditions. These classes check that the function works as expected or not.
There are some classes like system.assertequas() and system.assertnotequals(). These classes ensure that the code gets executed perfectly.
5. Testing for Bulk Data
You can either use apex trigger or user-triggered actions for data operations. Since it works on bulk data, it deals with large data sets with APIs. Your code should not breach the limits, otherwise, your code will get messed up terribly. All you need to do is to be clear about the limits and operate carefully. That’s it.
Once you have done with good unit tests, then executing it regularly has many benefits. The regular check will definitely avoid the bugs in your code. You can fix the issues before they become blockers.
Salesforce testing works both in the browser and in the eclipse environment. Both environments offer a great array of debugging tools. With test classes combined with these tools, it benefits your code.
Salesforce launched its Apex debugging tool called The Apex interactive debugger. There is also a chrome extension is available named salesforce lightning inspector. Both tools will be helpful in salesforce testing.
Always practice these above tips to make your salesforce testing easier.
