Running a Subset of Tests in a Deployment

If the code coverage of an Apex component in the deployment is less than 75%, the deployment fails. If one of the specified tests fails, the deployment also fails. We recommend that you test your deployment in sandbox first to ensure that the specified tests cover each component sufficiently. Even if your organization’s overall code coverage is 75% or more, the individual coverage of the Apex components being deployed can be less. If the code coverage requirement isn’t met, write more tests and include them in the deployment.

To run a subset of tests, add the testLevel="RunSpecifiedTests" parameter to the deploy target. Specify each test class to run for a deploy target in a <runTest> </runTest> child element within the sf:deploy element. Add the test class name within the <runTest> </runTest> tags. Add as many runTest tags as you need, one for each test class.

This deploy target example shows three test classes. Salesforce runs these test classes when deploying this package.

The test class name can include a namespace prefix. Add a namespace prefix if your organization has a namespace defined or if the test class belongs to a managed package. For example, if the namespace is MyNamespace, specify the test class as MyNamespace.TestClass1.

If you don’t specify a test class to run in the target, the default deployment behavior applies when deploying to production. The default is all tests in your organization run on deployment except the tests that originate from installed managed packages. The default code coverage requirements are also enforced. The requirements are a minimum overall percentage of 75% for all classes and triggers, and no trigger can have 0% coverage.
