Business Use case

Isabella Stewart is working as a Salesforce Administrator at Gurukul On Cloud (GoC). GoC is working with a third-party vendor to implement Field Service Lightning to improve customer experience. Isabella got a task from her manager to calculate the code coverage in PROD.

Guided Practice (We-do):

Code coverage is a testing technique that determines what code is being tested and what is not tested. It is often represented as a percentage of the number of lines of code tested for an Apex class or trigger.

Perform the steps below to get reliable code coverage:

Step 1: Compile All Test Classes

Navigate to Setup | Custom Code | Apex Test Execution.
Uncheck Store Only Aggregated Code Coverage.
Then, clear test history, by navigating to View Test History | Clear Test Data.
The last steps is to compile all test classes. By navigate to Setup | Custom Code | Apex Classes.

Step 2: Check Overall Code Coverage

Once the Apex unit tests are completed, check the overall code coverage for your org by following the instructions below:

Navigate to Setup | Custom Code | Apex Classes.
Click on Estimate your organization’s code coverage.

You can also run the below query to find out org-wide coverage. If querying from the Developer Console Query Editor, ensure you select Use Tooling API.

ApexOrgWideCoverage represents code coverage test results for an entire organization.

Copy Code



SELECT PercentCovered FROM ApexOrgWideCoverage

The following example SOQL query retrieves code coverage results for a specific class or trigger:

Copy Code


SELECT TestMethodName, NumLinesCovered, NumLinesUncovered FROM ApexCodeCoverage WHERE ApexClassOrTrigger.Name='AccountTrigger'
