Mountebank

In previous blog post, I have explained about how to create a json response in mountebank. You can read about that here and here. Recently , I had to test a scenario about what will happen to application if downstream API response is delayed for some time . Let us have a look about how we can use mountebank to simulate this scenario. Mountebank supports adding latency to response by adding a behaviour. You can read about that here . Let us try to implement the wait behaviour in one of the previous examples . This is a slight modification of the files used as part of examples mentioned here and here. You can clone my github repo and look at “ExamplesForWaitBehaviour” for the files. ...

In previous blogs here , I have explained how we return a XML response using mountebank. However , most of the time, we will have to make some modification to the template response before returning a response. Say for example, we may have to replace details like timestamp, or use an input from request parameter and update that in response etc. One of the easiest way to do this without using other frameworks like xml2js etc is to extract the substring between the node values and replace it . Below is a code snippet which will help to achieve this ...

Predicates in Mountebank imposter files is a pretty powerful way to configure stubs. It helps us to return different responses based on the request parameters like type, query string , headers, body etc. Let us have some quick look at extracting values from request Based on Query String Below is an example of extracting the records based on query string. If the request is like path?customerId=123&customerId=456&email=abc.com Note: This is slightly modified version of code in mbtest.org ...

Previous two blog post talked about how we can use mountebank for stubbing where responses are in json format . They can be accessed (here) and (here). We can use same approach for stubbing SOAP services using XML as well. In this post, I will explain how we can provide XML response using Mountebank . Let us have a quick look into the files created. Before we begin, folder structure of various file as below ...

This is an extension to my previous blog about how we can use mountebank to create a stubbed response based on a template file . You can read about it here. In this step by step example, I will explain how we will use mountebank to modify the response based on the request . Before we start, please ensure you are familiar with Part1 of the excercise. If you need to know more about mountebank and how to use mountebank , please read through how to install mountebank and service virtualisation using mountebank. ...

In the previous two blog post, I have explained about how to setup mountebank (here) and how to create a virtualised respone(here) . Now coming to more detailed use cases which we might encounter in daily life. In this blog post, I will explain how we can use mountebank to create a virtualised response based on a template response stored in a file and modifying certain fields in response based on the request coming through. ...

In current development world, there will be scenarios were both API and its consumers are developed in parallel. Inorder to decouple their dependencies, we can mock an api response using mountebank. In this example, I will explain how to get started with your first service virtualisation using mountebank. After installing mountebank as mentioned in here (Install Mountebank), we will proceed with configuring mountebank. It can be done in few ways. The method which I explain below is by using file based configuration. This involve setting up an imposter file and a stub response ...

What is Mountebank? In short mountebank is a open source service virtualisation tool . Mountebank uses imposters to act as on demand test doubles. Hence our test cases communicate to Mountebank and mountebank responds back with relevant stubs as defined. How to Setup Mountebank ? Installation can be done via two methods npm Mountebank can be installed as a npm package. Node.js should be installed for this option to work ...
