I have a question related to Salesforce.com Deployment. When we try to Validate/Deploy a new Change Set, am I right when I say that it will execute every single test affected by the Apex class / Visualforce page deployed?
(For example) If I
delete a record in my class, it will verify every single trigger associated (and their Unit testing) and make sure they do not return any error, have their
assertEquals right and have at least 75%?
If not, is it executing EVERY test class in the organisation?
