使用Hamcrest的地图平等
我想使用hamcrest断言两个地图是相等的,即它们具有相同的键集合指向相同的值。
I'd like to use hamcrest to assert that two maps are equal, i.e. they have the same set of keys pointing to the same values.
我当前最好的guess is:
My current best guess is:
assertThat( affA.entrySet(), hasItems( affB.entrySet() );
其中:
assertThat(T,Matcher)类型Assert不适用于参数(Set>,Matcher >>>)
The method assertThat(T, Matcher) in the type Assert is not applicable for the arguments (Set>, Matcher>>>)
ve还可以看到containsAll的变体,以及其他一些由hamcrest包提供的方法。任何人都可以指向正确的方向,或者我必须写一个自定义的匹配器吗?
I've also looked into variations of containsAll, and some others provided by the hamcrest packages. Can anyone point me in the right direction? Or do I have to write a custom matcher?
我想出的最短的方法是两个语句:
The shortest way I've come up with is two statements:
assertThat( affA.entrySet(), everyItem(isIn(affB.entrySet())));
assertThat( affB.entrySet(), everyItem(isIn(affA.entrySet())));
但你也可以这样做:
assertThat(affA.entrySet(), equalTo(affB.entrySet()));
取决于地图的实现。
