Running Apex tests on a particular org helps to monitor what aspect of your code?

Running Apex tests in a Salesforce organization is crucial for monitoring overall code coverage. Code coverage is a metric that indicates the percentage of your Apex code that is executed when a test is run. Achieving high code coverage is essential, as it ensures that your code functions correctly and reduces the likelihood of errors in production environments.

When you run Apex tests, the results reflect how much of your code is being exercised by the tests. Salesforce requires at least 75% code coverage on Apex classes and triggers in order for them to be deployable to a production environment. Consequently, the positive impact of running Apex tests extends beyond just ensuring functionality; it also promotes best practices in coding and testing, ultimately contributing to the overall quality and robustness of applications built on the Salesforce platform.

Understanding code coverage through these tests helps developers identify untested paths in their code, encouraging them to write additional tests where necessary. Therefore, focusing on overall code coverage aids in achieving reliable and maintainable codebases, which is essential for successful application development and deployment within Salesforce environments.
