What if a GSP test method within an app fails?
All GSP apps have appropriate test methods and code coverage. Without this coverage, we could not publish the app on the AppExchange.
However, you may find that some of our test methods fail in your Salesforce environment.
These failures usually happen because there are mandatory fields or validation rules in your Salesforce environment that our test methods do not include. In other words, the mandatory field or validation rule does not exist within the source environment for the app.
You do not need to be concerned about this.
The test methods within any managed package are not part of the routine when you deploy change sets from a sandbox to your production environment.
As a result, a test method failure within a GSP app will not interfere with how users work or the configuration enhancements you make to your Salesforce setup.
