Final answer:
In Copado, Apex tests can be executed on a sandbox, during a deployment, and additionally as part of a promotion process. Each test environment is crucial for ensuring stable and compatible code before new changes are pushed to production.
Step-by-step explanation:
We just saw how you can execute Apex tests on a sandbox and during a deployment, but there is still one more place where you can run Apex tests in Copado: a promotion. In Copado, routine operations such as running tests are important for maintaining the health and stability of applications. Specifically, the Copado platform allows for the execution of Apex tests in three distinct environments: a sandbox, during the deployment phase, and finally as part of a promotion process.
This ensures that code modifications do not have negative impacts on the application. Running tests in different environments helps identify environment-specific issues and guarantees that new changes are compatible with the existing system before they are promoted to the production environment.
