爲什麼當比較項目而不是列表時，我會得到'實際和正式的參數列表長度不同'？

Question

我嘗試運行這個JUnit測試並最終斷言：

ResponseExample responseExample = new ResponseExample(); 
responseExample.value = 4; 

assertThat(comparisonResult.latencyDelta.best.get(0),equalTo(responseExample)); 

其中

public List<ResponseExample> best; 

爲什麼會出現錯誤equalTo()？

第一個項目最好的類型爲ResponseExample

Error:(62, 9) java: no suitable method found for assertThat(com.w.routing.automation.dataModel.examples.ResponseExample,com.google.common.base.Predicate<com.w.routing.automation.dataModel.examples.ResponseExample>) 
    method org.junit.Assert.<T>assertThat(java.lang.String,T,org.hamcrest.Matcher<? super T>) is not applicable 
     (cannot infer type-variable(s) T 
     (actual and formal argument lists differ in length)) 
    method org.junit.Assert.<T>assertThat(T,org.hamcrest.Matcher<? super T>) is not applicable 
     (no instance(s) of type variable(s) T exist so that com.google.common.base.Predicate<T> conforms to org.hamcrest.Matcher<? super T>) 

Answer 1

我進口「CoreMatchers」和我應該輸入「匹配器」
