使用Realm和XCTest进行测试-权限被拒绝？

Question

Whenever I try to read or write from the Realm within an XCTest, I'm getting this permission denied error: "RLMException", "open() failed: Permission denied" .

Even after making sure that the default Realm is set to a different path ( RLMRealm.setDefaultRealmPath("TestRealm") ) before any test is run, the problem still persists.

I'd like to avoid losing simplicity by passing through a Realm with every model function to accommodate testing them. The docs state it's possible, but I can't seem to get it working.

RLMRealm.setDefaultRealmPath(_:) is expecting an absolute path to the Realm file, so "TestRealm" is not a suitable path. Changing that to a path that the process has write access to should fix your issue.
