SetUpFixture Attribute - jnm2/nunit-docs-wiki GitHub Wiki
This is the attribute that marks a class that contains the one-time setup or teardown methods for all the test fixtures under a given namespace. The class may contain at most one method marked with the OneTimeSetUpAttribute and one method marked with the OneTimeTearDownAttribute.
There are a few restrictions on a class that is used as a setup fixture.
-
It must be a publicly exported type or NUnit will not see it.
-
It must have a default constructor or NUnit will not be able to construct it.
The OneTimeSetUp method in a SetUpFixture is executed once before any of the fixtures contained in its namespace. The OneTimeTearDown method is executed once after all the fixtures have completed execution. In the examples below, the method RunBeforeAnyTests() is called before any tests or setup methods in the NUnit.Tests namespace. The method RunAfterAnyTests() is called after all the tests in the namespace as well as their individual or fixture teardowns have completed execution.
Multiple SetUpFixtures may be created in a given namespace. The order of execution of such fixtures is indeterminate.
A SetUpFixture outside of any namespace provides SetUp and TearDown for the entire assembly.
using System;
using NUnit.Framework;
namespace NUnit.Tests
{
[SetUpFixture]
public class MySetUpClass
{
[OneTimeSetUp]
public void RunBeforeAnyTests()
{
// ...
}
[OneTimeTearDown]
public void RunAfterAnyTests()
{
// ...
}
}
}Note: Prior to NUnit 3.0, SetUpFixture used the SetUp and TearDown attributes rather than OneTimeSetUp and OneTimeTearDown. The older attributes are no longer supported in SetUpFixtures in NUnit 3.0 and later.
