SequentialAttribute (NUnit 2.5)
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.
Example
The following test will be executed three times, as follows:
MyTest(1, "A") MyTest(2, "B") MyTest(3, null)
[Test, Sequential]
public void MyTest(
[Values(1,2,3)] int x,
[Values("A","B")] string s)
{
...
}
