Sequential

The SequentialAttribute is used on a test to specify that NUnit should generate test cases by selecting individual data items provided for the parameters of the test, without generating additional combinations.

[!NOTE] If parameter data is provided by multiple attributes, the order in which NUnit uses the data items is not guaranteed. However, it can be expected to remain constant for a given runtime and operating system. For best results with SequentialAttribute use only one data attribute on each parameter.

Example

The following test will be executed three times.

csharp

[Test, Sequential]
public void MyTest(
    [Values(1, 2, 3)] int x,
    [Values("A", "B")] string s)
{
    /* ... */
}

MyTest is called three times, as follows:

csharp

MyTest(1, "A")
MyTest(2, "B")
MyTest(3, null)
