Code coverage is a crucial metric for Salesforce developers, especially when working with Apex code. Not only is it a best practice to write well-tested code, but Salesforce also requires a minimum percentage of code coverage before deploying to production. In this blog post, we will explore what a code coverage report is, why it matters, and how to effectively use it in Salesforce.

What is Code Coverage?

Code coverage measures the percentage of your Apex code that is executed when your tests run. In other words, it shows how much of your codebase is actually being tested by your unit tests. Salesforce calculates code coverage by highlighting which lines of code were executed during test runs and which lines were not.

Why is Code Coverage Important?

Deployment Requirement: Salesforce mandates at least 75% code coverage for deploying Apex classes and triggers to production.
Quality Assurance: Higher code coverage generally means fewer bugs and more reliable code.
Identifies Gaps: Code coverage reports help identify untested portions of your code so you can improve test coverage and code quality.

How to create a Code Coverage report.

We can see the code coverage for each file in the developer console, but we can’t export it to Excel. You can now view overall and individual entity code coverage across your organization. The results of the code coverage can be downloaded in Excel format.
