问题描述
我希望AutoFixture生成两个整数,而对于第二个整数,我不希望它为0或先前生成的数字.有没有办法告诉AutoFixture兑现要求".
I want AutoFixture to generate two integers, and for the second one, I don't want it to be 0, or the previous generated number. Is there a way to tell AutoFixture to honor that "requirement".
看着RandomNumericSequenceGenerator
,我看起来像下限是1 ,因此我可能不必指定第一个要求.接下来,我正在查看播种"选项,但是如此答案所示,它将不会用于默认情况下是一个数字.
Looking at RandomNumericSequenceGenerator
, I looks like the lower limit is 1, so I might not have to specify the first requirement. Next, I was looking at the "seeding" option, but as indicated in this answer, it won't be used for a number, by default.
这里有什么我可以俯瞰的地方吗?
Is there something I'm overlooking here?
推荐答案
这是使用普通AutoFixture做到这一点的一种方法:
Here's a way to do this with plain AutoFixture:
[Fact]
public void GenerateTwoDistinctNonZeroIntegersWithAutoFixture()
{
var fixture = new Fixture();
var generator = fixture.Create<Generator<int>>();
var numbers = generator.Where(x => x != 0).Distinct().Take(2);
// -> 72, 117
}
这是使用 AutoFixture.Xunit 的一种方法:
[Theory, AutoData]
public void GenerateTwoDistinctNonZeroIntegersWithAutoFixtureXunit(
Generator<int> generator)
{
var numbers = generator.Where(x => x != 0).Distinct().Take(2);
// -> 72, 117
}
