Test Impact Analysis is only supported on dd-trace>= 2.22.0
(execute dd-trace --version
to get the version of the tool).
Prior to setting up Test Impact Analysis, set up Test Optimization for .NET. If you are reporting data through the Agent, use v6.40 and later or v7.40 and later.
Intelligent Test Runner Activation (intelligent_test_runner_activation_write
) 권한이 있는 조직의 사용자는 Test Service Settings 페이지에서 Intelligent Test Runner를 활성화해야 합니다.
After completing setup, run your tests as you normally do by using dotnet test or VSTest.Console.exe:
dd-trace ci run --dd-service=my-dotnet-app --dd-env=ci -- dotnet test
dd-trace ci run --dd-service=my-dotnet-app --dd-env=ci -- VSTest.Console.exe {test_assembly}.dll
You can override the Test Impact Analysis behavior and prevent specific tests from being skipped. These tests are referred to as unskippable tests.
Test Impact Analysis uses code coverage data to determine whether or not tests should be skipped. In some cases, this data may not be sufficient to make this determination.
Examples include:
Add a XUnit TraitAttribute
with the key datadog_itr_unskippable
to your test case to mark it as unskippable.
using Xunit;
using Xunit.Abstractions;
public class MyTestSuite
{
[Fact]
[Trait("datadog_itr_unskippable", null)]
public void MyTest()
{
// ...
}
}
Add a XUnit TraitAttribute
with the key datadog_itr_unskippable
to your test suite to mark it as unskippable.
If a suite is marked as unskippable, none of the test cases from that suite can be skipped by Test Impact Analysis.
using Xunit;
using Xunit.Abstractions;
[Trait("datadog_itr_unskippable", null)]
public class MyTestSuite
{
[Fact]
public void MyTest()
{
// ...
}
}
Add a NUnit PropertyAttribute
with the key datadog_itr_unskippable
and a non-null value (for example, string.Empty) to your test case to mark it as unskippable.
using NUnit.Framework;
public class MyTestSuite
{
[Test]
[Property("datadog_itr_unskippable", "")]
public void MyTest()
{
// ...
}
}
Add a NUnit PropertyAttribute
with the key datadog_itr_unskippable
and a non-null value (for example, string.Empty) to your test suite to mark it as unskippable.
If a suite is marked as unskippable, none of the test cases from that suite can be skipped by Test Impact Analysis.
using NUnit.Framework;
[Property("datadog_itr_unskippable", "")]
public class MyTestSuite
{
[Test]
public void MyTest()
{
// ...
}
}
Add a MsTestV2 TestPropertyAttribute
with the key datadog_itr_unskippable
to your test case to mark it as unskippable.
using Microsoft.VisualStudio.TestTools.UnitTesting;
[TestClass]
public class MyTestSuite
{
[TestMethod]
[TestProperty("datadog_itr_unskippable", null)]
public void MyTest()
{
// ...
}
}
