Can I dynamically generate unit tests

$begingroup$


kind of new to .NET and I'm trying to figure out if there's a better way for me to create my tests.



I'm writing an API that returns an object and I need to test that the return values match the expected results. Looks like this essentially:



Test files using partial to spread each input/result into it's own file:



public static partial class MyTests {
public static object Test1 {
inputs: new Inputs {...},
results: new Results {
value1 = 100,
value2 = 100,
value3 = 100,
}
},

public static object Test2 {
inputs: new Inputs {...},
results: new Results {
value1 = 100,
value2 = 100,
value3 = 100,
}
},

public static object Test3 {
inputs: new Inputs {...},
results: new Results {
value1 = 100,
value2 = 100,
value3 = 100,
}
},

}


Test class:



public class ServiceTests {

private ServiceRequest _request;
private ServiceResult _expectedResults;
private ServiceResult _response;
private ServiceCalc _service;
private const int DecimalPrecision = 4;

public void Setup(dynamic sampleData)
{
_request = sampleData.inputs;

_expectedResults = sampleData.results;

_service = new ServiceCalc(_request, Samples.Service.GetParams());

_response = _service.DoCalc();
}

public void EqualTest(decimal expected, decimal response)
{
Assert.AreEqual(
decimal.Round(expected, DecimalPrecision),
decimal.Round(response, DecimalPrecision)
);
}

[TestMethod]
public void Value1_1()
{
Setup(Samples.Service.Test1);
EqualTest(_expectedResults.value1, _response.value1);
}

[TestMethod]
public void Value1_2()
{
Setup(Samples.Service.Test2);
EqualTest(_expectedResults.value1, _response.value1);
}

[TestMethod]
public void Value1_3()
{
Setup(Samples.Service.Test3);
EqualTest(_expectedResults.value1, _response.value1);
}

[TestMethod]
public void Value2_1()
{
Setup(Samples.Service.Test1);
EqualTest(_expectedResults.value2, _response.value2);
}

[TestMethod]
public void Value2_2()
{
Setup(Samples.Service.Test2);
EqualTest(_expectedResults.value2, _response.value2);
}

[TestMethod]
public void Value2_3()
{
Setup(Samples.Service.Test3);
EqualTest(_expectedResults.value2, _response.value2);
}

[TestMethod]
public void Value3_1()
{
Setup(Samples.Service.Test1);
EqualTest(_expectedResults.value3, _response.value3);
}

[TestMethod]
public void Value3_2()
{
Setup(Samples.Service.Test2);
EqualTest(_expectedResults.value3, _response.value3);
}

[TestMethod]
public void Value3_3()
{
Setup(Samples.Service.Test3);
EqualTest(_expectedResults.value3, _response.value3);
}
}


Initially I wanted to put the assets in the same function and I would only have one test for each value with multiple assets for each test scenario but my senior wanted to be able to tell exactly which test scenario failed but I'm finding it pretty tedious to write out these test methods every time we want to create a new test scenario.



What is a better approach?
