If you are a Salesforce CPQ developer, then you must be aware of the code coverage concepts in Salesforce. Code coverage is considered to be an important technique because it gives an idea of how much code is being tested in the Apex system. The topics which we are going to cover under the Code coverage in salesforce are a brief introduction to code coverage, the importance of code coverage, best practices, and testing of code coverage in the Apex system. So let’s begin
If you are a Salesforce CPQ developer, then you must be aware of the code coverage concepts in Salesforce. Code coverage is considered to be an important technique because it gives an idea of how much code is being tested in the Apex system. The topics which we are going to cover under the Code coverage in salesforce are a brief introduction to code coverage, the importance of code coverage, best practices, and testing of code coverage in the Apex system. So let’s begin;
Code coverage is a commonly used technique in the Apex system. Code coverage in Salesforce is a software testing metric that determines the number of code lines that will be validated under testing procedures. It also helps many software companies to verify the end products to deliver high-quality end products. The formula to calculate code coverage is as follows;
Code coverage = (number of lines of code executed / total numbers line of code )* 100
The higher the coverage, the more thorough the testing, that is more the coverage, higher may be the quality. But it is persistent to mention that even after going for the 100% code coverage, the quality factor still is not guaranteed.
The following are the different types of code average available;

The primary purpose behind code coverage is to ensure that no line of code or area of the program is left untouched for the testing purpose. Through code coverage, we may be able to get the answers to the following questions.
Here we have listed a few benefits of the code coverage in salesforce:
At the beginning only we have mentioned that code coverage is commonly used in the Apex system. The Apex testing framework generates the code coverage numbers to monitor the Apex classes and triggers issues when you run one or more test cases.
In the following image, you can see how does code coverage used in the Apex system;
In a few scenarios where we can see those code coverage methods are filed to meet the test effectiveness in the Apex system. But you can make use of the code coverage as a tool to assess whether the codes require more testing or not. UAT (user assistance testing) is one such testing method that ensures the application behavior and quality of the code.

After running the code, you can see the code coverage information on the developer console of the test tab. In general, the code coverage panel consists of the following types of information;
Coverage information for each Apex class
Overall coverage for all the Apex codes in your organization.
Code coverage information is stored in two lightning platform tooling API projects such as ApexCodeCoverageAggregate and ApexCodeCoverage. The ApexCodeCoverageAggregate stores the sum of the lines covered for a specific class after checking all the test methods that test it. Whereas the ApexCodeCoverage stores the sum of the lines covered and uncovered by each individual test method. Users can query these objects using SOQL and API tooling integration to retrieve coverage information. Using SOQL is the best way to check for the coverage code and get more details.
Consider the below example;
In the above example, teh SOQL query gets the code coverage details for the class “TaskUtil”. The code coverage is aggregated from all the test cases in teh methods.
*note: to access SOQL query a tooling API is required. You can run SOQL queries with the help of the Query editor in the developer’s console -> check for the tooling API.
Here we have taken a few query examples that are partially covered by the test,
In the next example, you can see which test methods cover the classes in Apex. Usually, the query information consists of different object details, ApexCodeCoverage (it stores the coverage information by test class and methods).
The queasy result is as follows;
Here we are going to explain the major differences between the code coverage and test coverage:
