4. Unit tests
- (void)testClearNonPersistentCredentialsDoesNotClearPrivatePasswordPersistent
{
[self helper_setTestCredentialsPersistent:YES];
[self helper_setUpAccountTypePrivatePasswordPersistent:YES];
CPConfigService *cs = [[CPConfigService alloc] init];
[cs clearNonPersistentCredentials];
GHAssertEqualStrings(cs.dataPassword,
testDataPassword,
@"private password incorrectly cleared (%@)",
cs.dataPassword);
}
- (void)testClearNonPersistentCredentialsClearsPrivatePasswordNonPersistent {
[self helper_setTestCredentialsPersistent:YES];
[self helper_setUpAccountTypePrivatePasswordPersistent:NO];
CPConfigService *cs = [[CPConfigService alloc] init];
[cs clearNonPersistentCredentials];
GHAssertNil(cs.dataPassword,
@"private password not cleared (%@)",
cs.dataPassword);
}
