Analysis and Comparison of common software testing tools

Tool Name	Source	Type	Cost	Feature Overview
Winrunner	MercuryCompany	FunctionalityTest	Expensive	The most important function of winrunner is to automatically repeat a fixed testing process. It records a series of manual testing operations in the form of scripts and replays them in the same environment, check whether it is abnormal or not consistent with the actual results in the same environment. It can reduce the result errors caused by human factors, while also saving testers a lot of test time and energy to do other things. The functional modules mainly include GUI map, checkpoint, TSL Script Programming, batch testing, and data driver.
LoadRunner	Mercury	Performance and load pressure	Expensive	LoadRunner is an industrial standard load testing tool that predicts system behavior and performance. LoadRunner can test the entire enterprise architecture by simulating tens of millions of users to implement concurrent loads and real-time performance monitoring. By using LoadRunner, enterprises can minimize test time, optimize performance, and accelerate the release cycle of application systems. LoadRunner is an automatic load testing tool suitable for various architectures. It can predict system behavior and optimize system performance. LoadRunner's testing object is the entire enterprise system. It simulates the actual user's operation behavior and implements real-time performance monitoring to help you find and discover problems faster. In addition, it supports extensive protocols and technologies to provide special solutions for your special environment.
Quicktest pro	Mercury	Function TestingAnd regression testing	Expensive	QtpIt is a tool for automated functional testing of B/S systems, software program testing tools. Mercury's automated functional testing software quicktest professional can cover the vast majority of software development technologies, simple and efficient, and has the characteristics of reusable test cases. Mercury quicktest pro is an advancedAutomated TestingSolution for creating functions and regression tests. It automatically captures, verifies, and replays user interactions. Mercury quicktest pro provides the best industry solution to automate functions and regression testing for every important software application and environment.
Testdirector	Mercury	Test Management	Expensive	The web-based test management tool allows you to systematically control the entire test process and create the entire TestWorkThe framework and foundation of the stream make the entire test management process simpler and organized. He can help you maintain a test projectDatabaseAnd covers all functional aspects of your application. T also provides you with an intuitive and effective way to plan and execute Test Sets, collect test results, and analyze data. A complete defect tracking system is also provided. It can also work with Mercury's testing tools, third-party or self-developed testing tools, requirements andConfiguration ManagementIntegration of tools and modeling tools. You can use it to define requirements, test plans, test execution, and defect tracking, that is, all stages of the test process.
Silktest	Segue	Function Testing and regression testing	Expensive	Silktest is an automated function testing and regression testing tool for Web applications, Java applications, and traditional C/S applications. It provides features such as creation and customization of workflows for testing, test plan and management, direct database access and verification, and enables users to perform automated software testing efficiently. To improve the test efficiency, silktest provides multiple means to improve the automation of the test, including: test script generation, organization of test data, automation of test process, and analysis of test results. During the generation of the test script, silktest uses the dynamic recording technology to record user operations and quickly generate the test script. During the test, silktest also provides a unique recovery system that allows the test to run in 24x7x365 unattended conditions. When some errors cause the application to crash during the test, the errors can be found and recorded. After that, the tested application can be restored to its original basic state, to test the next test case.
Silkplan pro	Segue	Test Management	Expensive	Silkplan pro is a complete test management software for test plan management, document management, and management of various test behaviors. It can span all application lifecycles, automatic scheduling and execution from the early planning phase to the test design. It includes requirements inspection and confirmation, testing execution arrangements, and evaluation of product availability conditions. In addition, automatic web-based testing is provided. In the software development process, silkplan pro can automate the testing process. Silkplan pro provides Web-based management for all automated test cases.
Silkperformer	Segue	Load Stress Testing	Expensive	Silkmeanmer is the most advanced enterprise-level load testing tool in the industrial field. It can simulate thousands of users working in multi-protocol and multi-computing environments. With silkymmer, you can predict the performance of an enterprise's e-commerce application before it is deployed, regardless of its size and complexity. Visualized User Interface, real-time performance monitoring, and powerful management reports can help users solve problems quickly. Silkperformer provides elastic load testing capabilities for e-commerce applications in a wide range of situations. With truescale technology, silkscale mer can simulate thousands of concurrent users from a single computer, provides the required visual result validation function when minimal hardware resources are used. In an independent load test, silkmeanmer allows users to work in multi-protocol and multi-computing environments, and can accurately simulate the interaction between browsers and Web applications. Silkymmer's truelog technology provides a fully visualized cause analysis technology. By using this technology, you can visually process the data generated and received by users during the test process, including all the embedded object and protocol header information for visual analysis, you can locate and analyze problems even when an application error occurs.
