Replace line no. 68 in your test class i.e. PageReference result = AccountInvoiceTabExtension.autoRun() with below line of code
PageReference result = mc.NewInvoice();
Similarly test for other public methods for e.g. PageReference result2 = mc.sortConstructionPaginationList();

Thanks a lot @lalit Mistry

It is working now.

But I have another issue with my apex class for pagination, it is only covered by 19%
 
public class ListPaginationBase {
    
    public Integer listSize {get; set;}
    public Integer pageSize {get; set;}
    public Integer currentPageIndex {get; set;}
    public List<Object> fullList {get; set;}
  
    public void initializePagination(Integer listTotalSize, Integer singlePageSize) {
        fullList = new List<Object>();
        listSize = listTotalSize;
        pageSize = singlePageSize;
        currentPageIndex = 0;
    }
    
    public void initializePagination(List<Object> objectList, Integer singlePageSize) {
        fullList = ObjectList;
        listSize = fullList.size();
        pageSize = singlePageSize;
        currentPageIndex = 0;
    }
    
    public Integer getPageCount() {
        //Returns the number of pages required to show all data given a page limit
        //if page limit is not set or is equal to zero, then return 1; dont divide by zero
        //is empty list then return 1
        if (pageSize <= 0 || listSize <= 0)
            return 1;
        else
            return (Integer) Math.ceil((Decimal)listSize / (Decimal)pageSize);
    }
    
    public Boolean getHasNext() {
        //Returns true if the list has next pages
        return currentPageIndex < (getPageCount() - 1);
    }
    
    public Boolean getHasPrevious() {
        //Returns true if the list has previous pages
        return currentPageIndex > 0;
    }
    
    public Integer getfirstRowIndex() {
        //Returns the index of the first row to show in the PageBlockTable using the first attribute
        return currentPageIndex * pageSize;
    }
    
    public List<Object> getObjectPageList() {
        List<Object> returnList = new List<Object>();
        
        for(Integer index = getFirstRowIndex(); index < getFirstRowIndex() + pageSize; index++) {
            if (index < fullList.size()) {
                returnList.add(fullList.get(index));
            }
        }
        
        return returnList;
    }
    
    public PageReference firstAction() {   
        //Action fired when the user click the First Button
        //Set the Page Index to Zero
        if(getHasPrevious())
            currentPageIndex = 0;
        
        return null;
    }
    
    public PageReference lastAction() {
        //Action fired when the user click the Last Button
        //Set the Page Index to pages count - 1
        
        if(getHasNext())
            currentPageIndex = getPageCount() - 1;
        
        return null;
    }
    
    public PageReference nextAction() {
        //Action fired when the user click the Next Button
        //increment the current page index by 1
        if(getHasNext())
            currentPageIndex++;
        
        return null;
    }
    
    public PageReference previousAction() {
        //Action fired when the user click the Last Button
        //decrement the current page index by 1
        if(getHasPrevious())
            currentPageIndex--;
        
        return null;
    }
    
}

really appreciated
