How can I pass dynamic objects into an NUnit TestCase function?

Question

I am writing a data-intensive application. I have the following tests. They work, but they\'re pretty redundant.

[Test]
public void DoSanityCheck_WithCountEqu         


        

Answer 1

It would be much much easier to have a private method, base class method, or helper classes that do this for you.

For my unit tests, I need many many mock entities because it's a very data-intensive application. I've created a structure of mock repositories that can create initialized entities on the fly, which I can combine to build up a representative database structure in memory.

Something like that could work for you:

// Wild guess at the class name, but you get the idea
private void InitializeTotals(AggregateItem item)
{
    item.ItemCount = 0;
    item._volume = 0;
    item._houseGross = 1;
}

[Test]
public void DoSanityCheck_WithCountEqualsZeroAndHouseGrossIsGreater_InMerchantAggregateTotals_SetsWarning()
{
    InitializeTotals(report.Merchants[5461324658456716].AggregateTotals);

    report.DoSanityCheck();

    Assert.IsTrue(report.FishyFlag);
    Assert.That(report.DataWarnings.Where(x => x is Reports.WarningObjects.ImbalancedVariables && x.mid == 5461324658456716 && x.lineitem == "AggregateTotals").Count() > 0);
}

[Test]
public void DoSanityCheck_WithCountEqualsZeroAndHouseGrossIsGreater_InAggregateTotals_SetsWarning()
{
    InitializeTotals(report.AggregateTotals);

    report.DoSanityCheck();

    Assert.IsTrue(report.FishyFlag);
    Assert.That(report.DataWarnings.Where(x => x is Reports.WarningObjects.ImbalancedVariables && x.mid == null && x.lineitem == "AggregateTotals").Count() > 0);
}

[Test]
public void DoSanityCheck_WithCountEqualsZeroAndHouseGrossIsGreater_InAggregateTotalsLineItem_SetsWarning()
{
    InitializeTotals(report.AggregateTotals.LineItem["WirelessPerItem"]);

    report.DoSanityCheck();

    Assert.IsTrue(report.FishyFlag);
    Assert.That(report.DataWarnings.Where(x => x is Reports.WarningObjects.ImbalancedVariables && x.mid == null && x.lineitem == "WirelessPerItem").Count() > 0);
}
