Practices to master Salesforce Testing
Customer experience is utmost important for Salesforce. Therefore, right from the beginning, testing and quality are continually evaluated as part of their processes.
The purpose of testing in the digital environment involves many layers. It is used to check whether the code and configuration is functional, to ensure that the digital platform meets the requirement set by the client and post-testing, the software should completely support the requirement set by the client.
What does providing the best possible customer experience mean?
The testers at Salesforce are all software engineers who can perform white and black box testing and has talent much akin to a developer. That is the reason, testing at Salesforce is known as Quality Engineering (QE) instead of the more popular term Quality Assurance (QA). As developers and engineers work hand in hand quality feedback loops are in place and the work is achieved at much faster pace.
Their role is to design, write, maintain and develop complex test frameworks and set up test environments from scratch. They play an important and critical role in the release process of the codes developed and if they encounter any issues offer suggestions to implement changes.
Testing at Salesforce
Testing at Salesforce is completely done on their website and it is a rewarding experience as it brings some of the best practices, strategies and tools. The process covers both manual and automated testing.
Manual software testing involves testing Salesforce.com App by using systematic approach by a professional.
Automated testing involves a computer program to do the necessary check. These processes are used to test functional components of Salesforce App, load testing as well as security testing.
Then there is Apex that offer a testing framework to write unit tests, run the tests, check results and also generate code coverage results.
In the face of a crisis, distressing searches are made to find out if there is a clash with some inherent CSS or a class that might have been wrongly inherited.
Best practices and tools
In order to develop a forceful and error-free code, best strategies and tools in the practice are implemented.
Writing a proper test code includes creating suitable test records, running a test for it and placing the apt asserts to ensure that the code does what it is expected to.
Error free test codes are written for the most often used ‘Use Cases’ and the codes be inclusive of error cases. The focus must be on covering as much area as possible.
Further, though the code may use external data for validations or rely on data like usernames, it should not depend too much on the presence of external data. Too much dependency on external data will disrupt the functionality as it moves from development to production. The codes encompass the possibility of presence of null or not-present data. Relative URLs and SOQL queries can also be used for data records.
The general Salesforce instruction, excluding test methods and test classes mandates coverage of 75 per cent of the code in the unit test cases. It is only then that Salesforce allows deployment of apex code or package AppExchange apps. But the aim must be to reach 100 per cent coverage. Nevertheless, coverage may also be Use Case centric having tests done for all positive and negative use cases as well as for present and not-present data.
In case of conditional logic, it is necessary that every branch of the code logic and system assert methods must be used to demonstrate that code function is proper. It is also necessary to apply bulk trigger functionality and make use of at least 20 records in the tests. The application of ‘ORDER BY’ keywords guarantees that records are returned in projected order. However, it must not be assumed that the record IDs are in a serialised order.
In case of parallel testing, test run time can speed up. In case of logjams, data confusion or errors like ‘unable to lock row’ errors, turning off the parallel execution in the Salesforce user interface can help.
