Simple class to try and destroy all records in a Salesforce instance. Does not currently destroy Apex, or Visualforce, or Lightning components. It probably will never do the latter, I'm not sure I want it to do the former. Does not destroy custom metadata, but I'm looking into it. TODO: Parameters to avoid limits.

public void destroySimpleCRMStuff() {
//First clear out known dependents, leads and cases etc.
List<Case> cases = [SELECT ID from Case];
delete cases;
List<Lead> leads = [SELECT ID From Lead];
delete leads;
List<Opportunity> opportunities = [SELECT ID From Opportunity];
delete opportunities;
List<Contact> contacts = [SELECT ID from Contact];
delete contacts;
List<Account> accounts = [SELECT ID from Account];
delete accounts;
}

//ok, now we can go and dynamically delete **everything** else
Map<String, Schema.SObjectType> globalDescribe = Schema.getGlobalDescribe();
Set<String> sobjects = globalDescribe.keySet();
for(String so : sobjects) {
//not allowed in DML
//or has other restrictions where parent/dependents need to be removed first
//or simply does not support query
//or to support our code later
