I am preparing the testSetup() and I need to set the LastModifiedDate of the record one month earlier. Is that possible somehow?

Field is not writeable: Contact.LastModifiedDate

1 Answer 1


To create testdata with lastModifiedDate in the past follow the below link



Step 1- Create CSV File for your sobject

name createdDate lastmodifiedDate

Test1 2000-01-01T00:00:00Z 2001-01-01T00:00:00Z

Test2 2000-01-02T00:00:00Z 2001-01-02T00:00:00Z

Step 2 - save as Static Resource (named here as recordsWithLastModDateInPast)

Step 3 - Code test method

private static void testLastModDateInPast () {

    TestObj__c[] recordList = test.loadData(TestObj__c.sObjectType,'recordsWithLastModDateInPast');
  • Hey Chetan, can you add some context and code snippet explaining? It has often seen that links die and the answer becomes irrelevant then/ Sep 2, 2019 at 10:01
