What does it mean to have code coverage in apex?
The Apex testing framework generates code coverage numbers for your Apex classes and triggers every time you run one or more tests. Code coverage indicates how many executable lines of code in your classes and triggers have been exercised by test methods.
Why do you need unit tests in apex?
Write test methods to test your triggers and classes, and then run those tests to generate code coverage information. In addition to ensuring the quality of your code, unit tests enable you to meet the code coverage requirements for deploying or packaging Apex.
Why are test classes excluded from code coverage?
The corresponding test class isn’t shown. Test classes (classes that are annotated with @isTest ) are excluded from the code coverage calculation. This exclusion applies to all test classes regardless of what they contain—test methods or utility methods used for testing.
What does apexcodecoverageaggregate do for a class?
ApexCodeCoverageAggregate stores the sum of covered lines for a class after checking all test methods that test it. ApexCodeCoverage stores the lines that are covered and uncovered by each individual test method. For this reason, a class can have multiple coverage results in ApexCodeCoverage—one for each test method that has tested it.
How many lines of test coverage do apex triggers require?
Additionally, all Apex triggers require at least 1 line of test coverage to pass testing. Unfortunately, you have provided limited information in your question. It would be helpful if you could provide the code for your test class so we could determine why Salesforce is not executing your tests during deployment.
What are the unit test requirements for apex?
In addition to ensuring the quality of your code, unit tests enable you to meet the code coverage requirements for deploying or packaging Apex. 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.
How many test lines are covered by Apex trigger?
The trigger increases the total code lines in the organization from 50 to 100, of which only 50 are covered by tests. When Apex is deployed to production or uploaded as part of a package to the Salesforce AppExchange, Salesforce runs local tests in the destination organization.
How to query for Salesforce apex classes code coverage?
The code coverage panel includes coverage information for each Apex class and the overall coverage for all Apex code in your organization. However, you can also use SOQL queries with Tooling API as an alternative way of checking code coverage and a quick way to get more details. Let’s see how it works:
Why are test classes included with 0% code coverage?
The only reason I know is that I had the same exact issue. A while back our overall code coverage was including test classes with 0% code coverage. So for example, if I had a test class and a class I was covering at 100%, the overall code coverage would show up as 50%.
Where does 63% of code coverage come from?
Code coverage comes from test methods. You didn’t post any test methods, so it’s impossible to know where the 63% coverage comes from, or how to increase it.
How to increase code coverage of a test class?
If you test your code against enough different situations, you will naturally gain coverage.
