jsMockito方法调用断言未按预期工作
使用 QUnit + JsMockito 测试 Javascript 对象时，我在进行某些方法调用断言时遇到问题。基本基础设施工作正常：Qunit、JsHamcrest（Jsmockito 依赖项）和 Jsmockito 在套件定义中正确初始化。
我想断言对“dataStore#create”方法的调用，并以对象作为参数，如下所示：
var store = {create: function(arg) {}};
test("save()", function() {
var dataStoreMock = mock(store);
var objectUnderTest = { value: 'aaa',
dataStore: dataStoreMock,
save: function() {this.dataStore.create({name: this.value});}}
objectUnderTest.save();
verify(dataStoreMock).create({name: 'aaa'});
});
我收到断言错误：“想要但未调用：obj.create（等于 [object Object]）”
我的第一个怀疑是对象相等性没有按我的预期工作，证明是断言在传递原始数据类型而不是对象的调用上使用时有效：
this.dataStore.create(this.value); //actual code
verify(dataStoreMock).create('aaa'); //test
我尝试使用 jsHamcrest 'equalTo' 匹配器（如在 jsMockito 文档中公开）也没有成功：
verify(dataStoreMock).create(equalTo({name: 'aaa'}));
有人对如何使这种断言起作用有任何想法吗？
I'm having trouble making some method invocation assertions when testing a Javascript Object with QUnit + JsMockito. The basic infrastructure is working ok: Qunit, JsHamcrest(Jsmockito dependency) and Jsmockito are properly initialized at the suite definition.
I want to assert a call to "dataStore#create" method with an object as an argument, as follows:
var store = {create: function(arg) {}};
test("save()", function() {
var dataStoreMock = mock(store);
var objectUnderTest = { value: 'aaa',
dataStore: dataStoreMock,
save: function() {this.dataStore.create({name: this.value});}}
objectUnderTest.save();
verify(dataStoreMock).create({name: 'aaa'});
});
I get the assertion error: "Wanted but not invoked: obj.create(equal to [object Object])"
My first suspect is that object equality isn't working as i expected, the proof is that the assertion works when used on calls that passes primitive data types instead of objects:
this.dataStore.create(this.value); //actual code
verify(dataStoreMock).create('aaa'); //test
I tried to use jsHamcrest 'equalTo' matcher (as exposed at jsMockito docs) without success as well :
verify(dataStoreMock).create(equalTo({name: 'aaa'}));
Does anyone have any ideas on how to make this kind of assertion work?

断言正在检查对象本身，而不是其属性，并且 JsHamcrest 'equalTo' 匹配器不会对对象进行深入检查（它与 javascript '==' 运算符相同）。
您可以简单地检查它是否是一个对象：
或者有一个 JsHamcrest 匹配器“hasMember”，您可以将其用作：
如果您使用的是 jshamcrest 0.6.4 或更高版本（或当前的 HEAD），那么您还可以验证通过将匹配器作为第二个参数传递给 hasMember 来获取成员：
The assertion is checking the object itself, not its attributes, and the JsHamcrest 'equalTo' matcher does not do deep inspection of objects (it is the same as the javascript '==' operator).
You could simply check that it is an object:
or there is a JsHamcrest matcher 'hasMember', which you could use as:
If you're using a jshamcrest 0.6.4 or later (or the current HEAD), then you can also verify the member by passing matchers as a second argument to hasMember:
