What does 'Run Local Tests' imply in the context of deploying Apex components?

In the context of deploying Apex components, the term 'Run Local Tests' refers to the execution of all tests that are local to the changes being deployed, regardless of various other deployment settings. When this option is selected, it ensures that any relevant local tests are executed as part of the deployment process, which is critical for validating that the code behaves as expected before it is pushed to production.

By running local tests, the system checks the integrity and correctness of the new code in conjunction with existing functionalities. This thorough approach helps catch any potential issues upfront, thus reducing the risk of breaking existing functionality during deployments. It also allows the integration of testing practices within the development workflow to maintain high code quality standards.

The other options don't accurately capture the essence of what 'Run Local Tests' entails. For instance, suggesting that only local tests are executed doesn't encompass the requirement that all local tests related to the deployment must be run, reflecting a misunderstanding of the comprehensiveness of the process. Similarly, indicating that no tests will execute directly contradicts the purpose of the testing mechanism in place. The notion that tests run only for the last committed version fails to recognize the broader scope of what needs to be validated during a deployment, underscoring the necessity to examine all
