[英]Mock / stub with integration testing in Java
I'm using rest-assured for integration testing on my endpoints. 我正在使用可放心的端点上的集成测试。 One of the endpoints has a dependency to another resource (it calls another API conditionally).
端点之一对另一资源具有依赖性(它有条件地调用另一个API)。 Is there a way for me to stub out the API call so I can write a test for that case?
有没有一种方法可以对API调用进行存根处理,以便为该情况编写测试?
Lets say your code calls endpointB internally via http, you can stub that api by using https://github.com/katta/fakerest or https://github.com/azagniotov/stubby4j .So when your code makes a call internally to the another api, it will hit these stubs, which will return a dummy response always. 假设您的代码通过http内部调用了endpointB,则可以使用https://github.com/katta/fakerest或https://github.com/azagniotov/stubby4j对api进行存根处理,因此当您的代码在内部进行调用时另一个API,它将点击这些存根,并将始终返回虚拟响应。 Hope this helps.
希望这可以帮助。
interface IDataProvider {
string RetrieveData();
}
class StandardDataProvider : IDataProvider {
public string RetrieveData(){
// call to API
}
}
class Program {
private IDataProvider _dataProvider;
public Program(IDataProvider provider = null) {
_dataProvider = provider ?? new StandardProvider();
}
public void MethodToTest(){
var data = _dataProvider.RetrieveData();
// do your thing
}
}
In the tests you can mock the data by creating your own IDataProvider
object and working with its data. 在测试中,您可以通过创建自己的
IDataProvider
对象并使用其数据来模拟数据。
class TestDataProvider : IDataProvider {
public string RetrieveData(){
return "my own data";
}
}
class Test {
[TestMethod]
public void TestProgram(){
var obj = new Program(new TestDataProvider);
var result = obj.MethodToTest();
// asserts
}
}
