TestMace is an IDE for working with APIs. Product is currently in beta testing, but the current version is stable and has a number of important advantages that can be useful for QA professionals and developers.
Fiddler is known as a proxy debugger, and its ability to capture traffic from nearly any source means the fastest way to generate API tests is to simply capture the API traffic from an existing client and modify and augment those tests as desired.
The new APITest extension to Fiddler greatly enhances its power to validate the behavior of web APIs.
HttpMaster is a web development and test tool to automate testing of web sites and services, including RESTful web services and API applications, and monitor their responses.
With HttpMaster you can easily execute and monitor requests to simulate client activity; it can execute requests against various web servers and display complete request and response data.
HttpMaster is also able to generate high volume of web traffic for improved testing and comes in two editions; free Express edition and commercial Professional edition.
Apache JMeter is open-source software that is popular for performance testing and is designed to load test functional behavior and measure performance. Apache JMeter may be used to test performance both on static and dynamic resources, Web dynamic applications.
It can be used to simulate a heavy load on a server, group of servers, network or object to test its strength or to analyze overall performance under different load types.
JMeter can read your testdata from the CSV file out of the box. API can be tested with multiple sets of data easily.
JMeter has a ‘Response Extractor‘ s – which can be used to extract information from the API response (JSON / XML / Regular expression) and use it in the subsequent requests in the test.
You can easly integrate JMeter with Jenkins to run the test periodically and Jenkins has a plugin for JMeter to parse the result file & display nice charts.
Katalon Studio uses Apache Groovy, a scripting language for the Java platform. Groovy is a powerful dynamic language, which is ideal for creating test scripts. For test execution, Java libraries and Java compatible languages like JRuby and Jython are supported.
It has been a successful solution for many automation projects ranging from small to large teams for enterprise clients. Katalon Studio is free to use.
Katalon Studio supports the built-in integration with qTest, a powerful and easy-to-use test management system.
Katalon Studio is a test automation solution that leverages Selenium’s core engine. Although it uses several Selenium functionalities, it is not simply a Selenium wrapper.
Postman, a complete API development environment. With this app, developers are able to send requests, save responses, add tests, and create workflows.
Frequently, testers are required to perform an API testing and with an app like Postman this process becomes easy and it features a powerful and simple GUI, giving the ability to save the history of tested API requests, making reporting much easier.
RapidAPI is the world’s largest API marketplace where over half a million developers find and connect to thousands of public APIs.
RapidAPI processes 400 billion API calls each month. Its directory includes APIs from Microsoft, Stripe, SendGrid, Slack, Foursquare, Eventbrite, Yelp, Google Translate, Spotify, NASA, ProductHunt and more.
Rapise is a powerful and flexible software test automation platform that leverages the power of open architecture to provide the most rapid and flexible functional testing tool on the market today.
ReadyAPI allows you to build complex end-to-end functional, security, and performance tests with both the ease of an intuitive interface and the flexibility of an IDE.
ReadyAPI not only has a insightful dashboard built in for quick up-to-date testing metrics, but also outputs JUnit, HTML, CSV, or other customizable reporting formats.
REST-assured is a Java library that provides a domain-specific language (DSL) for writing powerful, maintainable tests for RESTful APIs.
REST-assured was designed to simplify the testing and validation of REST APIs and is highly influenced by testing techniques used in dynamic languages such as Ruby and Groovy.
The next API testing tool is Runscope.
A Runscope API test is a group of one or more HTTP requests executed sequentially to evaluate the uptime, performance and correctness of an API. For each step in the test, you can define Assertions to validate response data and Variables to extract data to be used in subsequent requests.
SOAPSonar provides automated testing of each API independent of client, device or intended Consumer. Automatically generating a UI to provide immediate feedback to developers, testers, integrators, and security professionals.
Fully automated, SOAPSonar requires no scripting or script maintenance, reducing time and skill level needed.
Regression testing can be automated, providing early identification of changes to the API or versions. Support for message and protocol layer identity standards allows for cloud testing.
SoapUI is the world’s leading Functional Testing tool for SOAP and REST testing.
With its easy-to-use graphical interface, and enterprise-class features, SoapUI allows you to easily and rapidly create and execute automated functional, regression, and load tests.
In a single test environment, SoapUI provides complete test coverage – from SOAP and REST-based Web services, to JMS enterprise messaging layers, databases, Rich Internet Applications, and much more. And that’s just the beginning.
