![]() ![]() Follow Jenkins documentation to install Jenkins and create Jenkins jobs.Ĭreate API test cases in TestRail by adding test description and expected outcome.Īfter test cases creation completed, then create Test Run and add test cases to the test run. Required if you want to run a Postman test with Jenkins CI. To install docker please follow docker installation for your platform. Required if you want to run Newman inside docker container. To install newman, newman-reporter-htmlextra and newman-reporter-testrail, open terminal and run the following command: npm install -g newman newman-reporter-htmlextra newman-reporter-testrail Environment Variable for TestRail integrationĭownload and install NodeJS here! After successful installation, open terminal and run node -v to verify, it should show the node version.Validation for each attribute name/value/data type.ĪPI testing with Postman and TestRail Requirement.Response body schema, is a valid JSON Schema as per API contract.Response body, for REST API validation.Response time, acceptable response time e.g 1000ms.HTTP header Content-Type value if any, e.g for REST API testing, Content-Type value should be application/json.Automate API testing for continuous testing with CI/CD tools such as Jenkins.įor API testing the following items are mandatory to be validated.Have a good communication between developers, business analysts, testers and clients.Leverage API mock to validate request and response of API test scripts while waiting for development to complete. ![]() Start creating API tests soon after API contracts are available.API contracts are completed and prioritized.The following should help testers and developers testing the API more effectively during the development phase. In today’s Agile development, due to limited time, API test scenarios don’t always get tested completely. TestRail provides the following features. Its intuitive web-based user interface makes it easy to create test cases, manage test runs and coordinate the entire testing process. TestRail helps to manage and track software testing efforts and organize the QA department. Postman is a collaboration platform for API development, simplifying each step of building an API and streamline collaboration to create better APIs. In this article, we will focus our discussion on Postman as the selected API tool and it’s integration to TestRail as the TestCase Management System. There are many tools available for API testing. Regression testing is a test to assure the current functions of the application are not broken from the addition of the new code or changes introduced by bug fixes. This type of testing is performed during active sprints. Progression testing or incremental testing focuses on the new functionality to ensure it works according to the requirements. ![]() This article will be focusing more on Functional testing, for both Progression and Regression testing. There are number of variant types of API Testing that we use at Ice House in our methodology as follow:Ī level of test that focuses on individuals of software components, also known as white-box testing.Ī level of test that focuses on interactions between components or systems.Ī test that is performed to evaluate if a component or system satisfies functional requirements.Ī test to determine the performance of a component or system.Ī test to determine the security of the software product. API interchange data using JSON on top of HTTP protocol, validate its request and response regardless of the underlying technologies. No user interface required while performing API testing makes it easier to integrate. Because of its efficiency and faster run time compared to UI testing, testers can create extraordinary inputs and conditions and push applications to its limits. Testers can start API testing before development is completed with the help of API contracts. Faster and less time consuming during test run compared to UI design testing.Following are several benefits of API testing. It can be done by both developers and testers before development is completed with help of API contracts. Why API testing and what is the benefit of API testing?ĪPI testing creates a more reliable code since it works at a lower level. ![]() The most common protocol used in API is HTTP with REST. Traditional testing focuses on the UI, validating look and feel, buttons and fields of the UI interface, while API testing focuses more on business logic, data response, performance and security. API testing consists of a request sent to an API endpoint and a set of assertions that validates the response. In today’s software development, API becomes a center of data transformation and transmission between different systems. ![]()
