[英]Flutter: testing
I was trying to test this function 我正在尝试测试此功能
UserApi createUserApi(String url, String username, String password) {
UserApi userApi = new UserApi(base: route(url), serializers: repo);
userApi.base.basicAuth('$username', '$password');
return userApi;
}
basically, the test was to compare the result of this function with a "manually composition" of it, expecting to have the same result. 基本上,测试是将该功能的结果与该功能的“手动组合”进行比较,以期得到相同的结果。 But It doesn't:
但这不是:
String username = "asd";
String password = "asd";
UserApi userApiTest = new UserApi(base: route("asd"), serializers: repo);
userApiTest.base.basicAuth('$username', '$password');
test("UserApi creation", () {
UserApi userApi = _presenter.createUserApi("asd", "asd", "asd");
expect(userApi, userApiTest);
});
The result is always : 结果始终是:
Expected: <Instance of 'UserApi'>
Actual: <Instance of 'UserApi'>
Why are they different? 他们为什么不同? In the debug every property is the same.
在调试中,每个属性都是相同的。
You have two different instances of UserApi
. 您有两个不同的
UserApi
实例。 Them having the same property values does not make them equal. 它们具有相同的属性值并不会使它们相等。
You would need to implement hashCode
and operator==
. 您将需要实现
hashCode
和operator==
。 By default only comparing the references to the same instance of an object are considered equal (because they are identical) 默认情况下,仅将引用与对象的相同实例进行比较才视为相等(因为它们相同)
