问题描述
在hamcrest(1.3.RC2,没有JUnit依赖)
我没有使用 iterableWithSize()。
我有一个(扩展) Iterator
参数化为 Content
像这样
EndResult<内容> contents = contentRepository.findAllByPropertyValue(title,* content *);
其中 EndResult
是
package org.springframework.data.neo4j.conversion;
public interface EndResult< R>扩展了Iterable< R> {...}
和内容
是我的Pojo。
现在,我认为这将工作
assertThat(contents,iterableWithSize(1));
类型Assert中的方法assertThat(T,Matcher)
不适用
作为参数
(EndResult< Content>,Matcher< Iterable< Object >>)
我试过这些失败:
assertThat(contents,iterableWithSize(equalTo(1));
assertThat(contents,IsIterableWithSize。< EndResult< Content>> .iterableWithSize(1));
这些是我的进口:
导入静态org.hamcrest.CoreMatchers.equalTo;
导入静态org.hamcrest.collection。 IsCollectionWithSize.hasSize;
import static org.hamcrest.collection.IsIterableWithSize.iterableWithSize;
import static org.junit.Assert.a ssertEquals;
import static org.junit.Assert.assertThat;
import org.hamcrest.collection.IsIterableWithSize;
集合的hasSize按预期工作,但对于迭代器,我甚至找不到一个工作示例...
它应该是
assertThat(contents,IsIterableWithSize。< Content> iterableWithSize(1));在上键入
iterableWithSize
您的 Iterable
的组件类型,而不是iterable本身的具体类型。
In hamcrest (1.3.RC2, with no JUnit dependencies) I am failing using iterableWithSize().
I have an (extension of) an Iterator
parametrized with Content
like thisEndResult<Content> contents = contentRepository.findAllByPropertyValue("title", "*content*");
where EndResult
is package org.springframework.data.neo4j.conversion;
public interface EndResult<R> extends Iterable<R> {...}
and Content
is a my Pojo.
Now, I would think that this would work assertThat(contents, iterableWithSize(1));
but it gives me the error :The method assertThat(T, Matcher) in the type Assert is not applicable for the arguments (EndResult< Content>, Matcher< Iterable< Object>>)
I also tried these failures :
assertThat(contents, iterableWithSize(equalTo(1));
assertThat(contents, IsIterableWithSize.<EndResult<Content>>.iterableWithSize(1));
These are my imports :
import static org.hamcrest.CoreMatchers.equalTo; import static org.hamcrest.collection.IsCollectionWithSize.hasSize; import static org.hamcrest.collection.IsIterableWithSize.iterableWithSize; import static org.junit.Assert.assertEquals; import static org.junit.Assert.assertThat; import org.hamcrest.collection.IsIterableWithSize;
The hasSize for collections works as expected, but for iterators I cant even find a working example...
It should just be
assertThat(contents, IsIterableWithSize.<Content>iterableWithSize(1));
iterableWithSize
is typed on the component type of your Iterable
, not the concrete type of iterable itself.
