[英]How to pass string and dictionary in NUnit test cases?
I want to make test for my method and I can pass 2 string variables, but I don't know how to pass the Dictionary<,>
. 我想测试我的方法,我可以传递2个字符串变量,但我不知道如何传递Dictionary<,>
。
It looks like this: 它看起来像这样:
[Test]
[TestCase("agr1", "askdwskdls", Dictionary<TypeMeasurement,double>)]
public void SendDataToAgregator_GoodVariables_ReturnsOn(string agrID,string devID, Dictionary<TypeMeasurement, double> measurement)
{
}
TypeMeasurement
is enum
and I know that this is not how you pass dictionary, but I don't know how, so I place it there so that you know what I want to do. TypeMeasurement
是enum
,我知道这不是你传递字典的方式,但我不知道怎么做,所以我把它放在那里让你知道我想做什么。
Instead of TestCaseAttribute
, if you have complex data to use as a test case, you should look at TestCaseSourceAttribute
如果您有复杂的数据用作测试用例,而不是TestCaseAttribute
,您应该查看TestCaseSourceAttribute
TestCaseSourceAttribute is used on a parameterized test method to identify the property, method or field that will provide the required arguments TestCaseSourceAttribute用于参数化测试方法,以标识将提供所需参数的属性,方法或字段
You can use one of the following contructors: 您可以使用以下某个构造函数:
TestCaseSourceAttribute(Type sourceType, string sourceName);
TestCaseSourceAttribute(string sourceName);
This is explantion from the documentation : 这是文档中的解释 :
If sourceType is specified, it represents the class that provides the test cases. 如果指定了sourceType,则它表示提供测试用例的类。 It must have a default constructor. 它必须具有默认构造函数。
If sourceType is not specified, the class containing the test method is used. 如果未指定sourceType,则使用包含测试方法的类。 NUnit will construct it using either the default constructor or - if arguments are provided - the appropriate constructor for those arguments. NUnit将使用默认构造函数构造它,或者 - 如果提供了参数 - 将为这些参数构造适当的构造函数。
So you can use it like below: 所以你可以像下面这样使用它:
[Test]
[TestCaseSource(nameof(MySourceMethod))]
public void SendDataToAgregator_GoodVariables_ReturnsOn(string agrID,string devID, Dictionary<TypeMeasurement, double> measurement)
{
}
static IEnumerable<object[]> MySourceMethod()
{
var measurement = new Dictionary<TypeMeasurement, double>();
// Do what you want with your dictionary
// The order of element in the object my be the same expected by your test method
return new[] { new object[] { "agr1", "askdwskdls", measurement }, };
};
