My goal for this class is to run for every missing day up until today, with just one call from an anon block.
I would like some assistance with creating a dynamic soql query that will work within the batch apex Database.getQueryLocator. As many of you probably know, there are three required functions within batch apex (Start, execute and finish). I am specifically talking about the start method that query all of the records that will be batched through. I've narrowed down the issue to be the bind variable missingDate. The original variable is being pulled from the argument I give in the constructor from the anon block. It is then used again after being modified to the next day in the finish function to call the next day.
The query works when I run it in an anon block after assigning the variable but returns nothing when testing.
Updated after Rubens Initial Comment(Thank you again):
public class MasterInventoryMissingBatchCleanUp implements Database.Batchable<sObject>{
public Date missingDate;
public MasterInventoryMissingBatchCleanUp(Date missingDate){
this.missingDate = missingDate;
}

Testclass also after Ruben's initial comment:

}
@istest static void test() {

MasterInventoryMissingBatchCleanUp miTest = new MasterInventoryMissingBatchCleanUp(twoDaysAgo);

Test.stopTest();
Integer expectedRecords = [SELECT COUNT() FROM Stock_Entry__c];
System.assertEquals(expectedRecords, [SELECT COUNT() FROM Master_Inventory__c], 'There are not ' + expectedRecords + ' records');
}
}
What this test returns:
System.AssertException: Assertion Failed: There are not 3 records: Expected: 3, Actual: 0
