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.

How does Salesforce calculate code coverage?
then we know n2/n1 will be 70%, and n4/n3 will be 95%, but the new code coverage will be (n2+n4)/(n1+n3) “total lines covered (new and existing) divided by the total number of lines to cover (new and existing)” So if n1=10,000, n2 = 7,000, n3 = 100, and n4 = 95, new code coverage will be (95+7000)/(10000+100) = 70.25% 2.

What does 75% code coverage mean?
It means that the overall code coverage of other existing components (trigger and classes) in production is below 75% and the deployment will not be successful. To avoid this: Ensure that all classes/triggers have above 75% code coverage and. All classes should be valid.
How much code coverage is enough in Salesforce?

Purpose of code coverage in salesforce

Importance of code coverage in Salesforce
Here we have listed a few benefits of the code coverage in salesforce:
Testing and 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.
Inspecting code coverage
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;
Code coverage VS test coverage
Here we are going to explain the major differences between the code coverage and test coverage:
Code coverage best practices
Consider the following tips while working on code coverage in salesforce:
How Is Code Coverage Calculated?
Code coverage percentage is a calculation of the number of covered lines divided by the sum of the number of covered lines and uncovered lines. Only executable lines of code are included. (Comments and blank lines aren’t counted.) System.debug () statements and curly brackets are excluded when they appear alone on one line. Multiple statements on one line are counted as one line for the purpose of code coverage. If a statement consists of multiple expressions that are written on multiple lines, each line is counted for code coverage.
Where to find code coverage in Apex?
After running tests, you can view code coverage information in the Tests tab of the Developer Console. The code coverage pane includes coverage information for each Apex class and the overall coverage for all Apex code in your organization.
How many transactions does Salesforce handle?
Salesforce handles over 1,000,000,000 transactions per day, no simple feat, and it requires a lot of hardware. Unit tests help make sure that your code is functioning within normal parameters to help give a better experience for everyone.
What is Salesforce multi tenant?
Salesforce is ‘multi-tenant’ meaning that lots of companies and their users are hosted on the same physical platform as one-another. That being the case, its important that any custom code installed on the platform is robust.
What is 90% coverage?
In all but the most simple code, 90% coverage should be the value you look to achieve, being that 100% is usually nearly impossible, and 75% is the minimum, so you want some “breathing room” for deployment; you have to write the unit tests after the code you’re testing, unlike some systems, where you write the unit tests first then make code that meets the test.
What does code coverage mean in Salesforce?
Code coverage indicates how many executable lines of code in your classes and triggers have been exercised by test methods. To deploy Apex or package it for the Salesforce AppExchange, unit tests must cover at least 75% of your Apex code, and those tests must pass.
Where to find code coverage in Apex?
You can view code coverage in several places in the Developer Console. The Tests tab includes an Overall Code Coverage panel that displays the code coverage percentage for every Apex class in your organization that has been included in a test run. It also displays the overall percentage.
How to see percentage of code covered in a test?
If you want to reopen the Coverage tool window, select Run | Show Code Coverage Data from the main menu, or press Ctrl+Alt+F6 . The report shows the percentage of the code that has been covered by the tests. You can see the coverage result for classes, methods, and lines.
How does code coverage affect code percentage?
We know code coverage is dependent on the total number of lines of code, so if there’s any insertion or deletion of code, it would affect the code percentage. For example, let’s say an organization has 50 lines of code covered by test methods. If you add a trigger that has 50 lines of code not covered by tests, the code coverage percentage drops from 100% to 50%. The trigger increases the total code lines in the organization from 50 to 100, of which only 50 are covered by tests.
What is Salesforce testing?
Testing is an important part of the Software Development Life Cycle (SDLC). Before moving the code in production, Salesforce ensures that your code has a minimum of 75% code coverage. This means that you have tested your code and it would not break in the production environment.
Why assign low coverage test classes?
The deployment on higher orgs is done by a specific person or an individual (release Manager). It is better to assign the low coverage test classes to the same person who created them for reworking .
What is ApexCodeCoverageAggregate?
Here ApexCodeCoverageAggregate represents the code coverage test results for an Apex class or trigger.
Does managed package testing include code coverage?
We should know that the overall test coverage of the organization doesn’t include the managed package tests. The exception may arise when the managed package tests cause your trigger to fire. The code coverage computed in a deployment after running all tests through the RunAllTestsInOrg test level includes coverage of managed package code. If you are running managed package tests in a deployment through the RunAllTestsInOrg test level, we recommend that you run this deployment in a sandbox first or perform a validation deployment to verify code coverage.
