This makes JMeter one of the top SaaS test automation tools<\/a> for performance testing.<\/p>\n\n\n\n Best features<\/strong><\/p>\n\n\n\n Pricing<\/strong>: Free, as it\u2019s open-source<\/p>\n\n\n\n Use cases<\/strong><\/p>\n\n\n\n How to use<\/strong><\/p>\n\n\n\n Since it\u2019s a free tool, you can easily start by downloading and launching it on your machine. Build a simple Test Plan with a Thread Group and an HTTP Request sampler. Now hit the run button and get live metrics to see how your app is performing under load.<\/p>\n\n\n\n Limitations<\/strong><\/p>\n\n\n\n JMeter doesn\u2019t support JavaScript, AJAX, or Flash natively. And since it works at the protocol level, it cannot render web pages like a browser.<\/p>\n\n\n\n Robot Framework <\/a>is an automation framework for Acceptance Test-Driven Development (ADD), Robotic Process Automation (RPA), and acceptance testing<\/a>.<\/p>\n\n\n\n You can write tests using keywords and reuse them across different test cases to reduce redundancy. The framework is mainly written in Python, but can be extended with different libraries.<\/p>\n\n\n\n Best features<\/strong><\/p>\n\n\n\n Pricing: <\/strong>Free, as it\u2019s an open-source tool<\/p>\n\n\n\n Use cases<\/strong><\/p>\n\n\n\n How to use<\/strong><\/p>\n\n\n\n Limitations<\/strong><\/p>\n\n\n\n While the keyword-driven approach is user-friendly and works well for basic tasks, you might find it tough to write more complex logic. Also, heavy reliance on third-party libraries might add to the complexity in terms of maintenance.<\/p>\n\n\n\n Postman is a platform for developing, testing, and deploying your SaaS app\u2019s APIs. It simplifies each step of the API lifecycle so you can create better APIs faster.<\/p>\n\n\n\n The tool allows you to create dynamic requests by defining variables that you can reuse across multiple requests and environments, like development, staging, and production. This makes Postman one of the most popular SaaS testing tools for APIs.<\/p>\n\n\n\n Best features<\/strong><\/p>\n\n\n\n Pricing<\/strong><\/p>\n\n\n\n Use cases<\/strong><\/p>\n\n\n\n How to use<\/strong><\/p>\n\n\n\n Sign up for Postman\u2019s free plan, create a collection of API requests, and use the \u201cTests\u201d tab to drop in a simple assertion, say, check that the status code is 200. Run your collection with the Collection Runner to execute all requests and check which tests are passing\/failing.<\/p>\n\n\n\n Limitations<\/strong><\/p>\n\n\n\n Postman might become slow if you\u2019re working with very large collections or responses, particularly on machines with limited resources. Advanced features such as API monitoring and team workspaces with higher usage limits are available only in paid tiers.<\/p>\n\n\n\n Related read:<\/strong> Top 21 API Automation Testing Tools<\/a><\/p>\n\n\n\n Ranorex is one of the SaaS testing tools that supports functional UI automation for web, mobile, and desktop apps.
