What typically varies during deployment in Copado concerning Apex test levels?

The correct answer relates to the default Apex test level, which defines how Apex tests are treated during the deployment process. In Copado, the force of testing is a critical aspect of ensuring code quality and functionality. The Apex test level can vary between deployments depending on the specific requirements and settings configured for each deployment.

When adjustments are made, such as during a change set or Continuous Integration process, the default Apex test level chosen will determine which tests need to be executed. This can range from running no tests to running all tests in the system. The flexibility to modify the default Apex test level allows teams to tailor their deployment strategy based on specific needs, such as minimizing runtime during testing or adhering to best practices by ensuring comprehensive testing.

Other options, while relevant to the deployment process, do not directly relate to the variability of Apex test execution levels. Thus, the significance of the default Apex test level as it relates to deployment parameters makes it the focused aspect of this question.
