With the gradual improvement of software testing, the importance of testing has gradually become apparent, and the application of testing tools has become a general trend. There are already many tools for testing. The application of testing tools can improve the quality and efficiency of testing, reduce repetitive work during testing, and automate testing, these testing tools can generally be divided into white box testing tools, black box testing tools, performance testing tools, as well as testing management tools. This article analyzes and compares the commonly used testing tools.

1. white box testing tools

White-box testing tools are generally used to test the code. The defects found in the testing can be located at the code level. Based on the principle of the testing tool, they can be divided into static testing tools and dynamic testing tools. The static test tool directly analyzes the code and does not need to run the code or compile links to the Code to generate executable files. Static testing tools generally scan the code syntax to find out areas that do not comply with the coding specifications, evaluate the code quality based on a certain quality model, and generate a system call relationship diagram; different from static testing tools, dynamic testing tools generally use plug-ins to insert some monitoring code into the executable file generated by the Code, used to count the data when the program is running. The biggest difference from static testing tools is that dynamic testing tools require the actual operation of the tested system.

(1) jtest

It is an integrated, easy-to-use, and automated Java unit testing tool for code analysis, dynamic classes, and component testing. It enhances code stability and prevents software errors.

(2) jcontract

Whether jcontract works correctly and is used correctly in the system-level verification class/component. Jcontract is an independent tool that is complementary to jtest in terms of functionality. You can use jcontract to plug in the Java code annotated by DBC. When you assemble a class/component into a system, jcontract monitors and reports errors and functional issues at runtime. Jcontract helps each developer effectively assess the system-level behaviors of classes/parts.

(3) c ++ Test

C ++ test can help developers prevent software errors and ensure code integrity, reliability, maintainability, and portability.

C ++ test automatically tests C and C ++ classes, functions, or components without writing a single test instance, test driver, or pile call.

(4) CodeWizard

CodeWizard static code analysis tool, advanced C/C ++ source code analysis tool, uses more than 500 encoding specifications to automatically mark dangerous, but the compiler cannot check the code structure.

(5) insure ++

Insure ++ is a precise detection tool based on C/C ++ for Automatic Memory Errors and memory leaks. Insure ++ can visualize real-time memory operations and accurately detect the root cause of Memory leakage. Insure ++ can also perform coverage analysis to clearly indicate that the code has been tested.

(6). Test

. Test is a convenient automated unit-level test and static analysis tool designed for. NET development. Use more than 200 Industrial Standard Code rules to automatically perform static analysis on written code. These rules immediately apply. NET industry experts with in-depth and comprehensive programming knowledge to your code to quickly and thoroughly prevent errors. Automatically test the code construction and functions. . Test is very intelligent. It can extract the just-completed Code, read it, and propose how to perform unit tests on the code without human interference. All unit tests generated by. test can be customized.

(7) boundschecker

Boundschecker visual c ++ edition is the preferred runtime error detection and debugging tool for Visual C ++ developers. It accelerates application development by automatically debugging and processing programs residing in the Visual C ++ development environment and shortens product release time. Boundschecker provides clear and detailed analysis for most programming errors in C ++. It can detect and diagnose static, stack memory errors, and memory and resource leaks. In the running status, boundschecker verifies over 8,700 APIs and Ole methods, including the latest Windows APIs, ODBC, ActiveX, DirectX, COM, and Internet APIs.

(8) truetime

Slow code execution is an important issue in the development process. The program running speed of an application is slow, and it is difficult for programmers to find out where the problem occurs. If the problem cannot be solved, the performance of the application will be reduced and the quality of the application will be greatly affected, so finding and modifying performance bottlenecks is the key to adjusting the overall code performance. How can we quickly find performance bottlenecks? The emergence of truetime makes this problem easy. When we test a program, truetime can provide the call time of the function in this conversation every time the application is completed, and provides detailed analysis of the application and component performance, and the code that runs slowly is automatically located. This will help programmers adjust the application performance as soon as possible. Truetime supports the C ++, Java, and Visual Basic language environments.

(9) failsafe

Failsafe is an automatic error handling and recovery tool in the Visual Basic language environment. failsafe inserts additional code to plug your program. When the program is executed, failsafe uses these plug-ins to capture and record error messages.

(10) jcheck

Jcheck is a component of the devpartner Studio development and debugging tool. It uses event debugging technology to collect accurate real-time information in Java program running. We often use threads in Java programs, and common thread errors include deadlocks, system crashes, and synchronization issues. Jcheck monitors and analyzes the running status of all threads in the current memory, finds the root cause of the error, and can locate the method in the program that has an error and the row where the error is located.

(11) truecoverage

Truecoverage is a code coverage rate statistical tool. during development, if you perform a manual test on an application, the code function is not detected, in other words, it takes a lot of time to detect the calls of each function one by one. We cannot guarantee the reliability of undetected code. In the future, program failures may be caused by undetected code. Now we can use truecoverage to help us solve these problems. Every time we test a program, every time we finish an application, truecoverage will be able to list the number and percentage of calls to all functions in this conversation, and can be directly located in the source code. Of course, we can also combine multiple application channels for detection. Therefore, truecoverage can help the development team save time and improve code reliability by measuring and tracking code execution and code stability. Truecoverage supports the C ++, Java, and Visual Basic language environments.

(12) smartcheck

Smartcheck is a major automatic error detection and debugging tool for Visual Basic. It can automatically detect and diagnose errors during the VB runtime, and convert some unclear error information to the exact error description. Its eventdebugging feature provides a simple solution for Visual Basic development teams and independent developers to solve the most difficult problems. It can analyze critical errors, Check compatibility, and locate source code.

Not all problems in Visual Basic are runtime or system errors. Many problems come from the results of unexpected program processes. Without eventdebugging, it is quite difficult or even impossible to separate the problem. When simple motion occurs, such as setting control attributes, some events that programmers cannot imagine will be triggered, making error detection and debugging more complicated. Smartcheck displays the properties, methods, and events used to isolate these event-driven problems. Smartcheck eventdebugging tracks events to simplify error locating. For example, smartcheck displays all its methods and attributes when an event is set or read-only, together with the form triggered by these events.

(13) codereview

For Visual Basic developers, codereview is the best automatic source code analysis tool, it performs Strict Source Code checks on hundreds of potential problems of application components, logic, windows, and VB. The types of codereview analysis include Y2K, logical errors, application performance and availability issues, Windows API calls, and standard consistency issues. It can detect the entire VB project or specified module, and customize the error detection types. It provides detailed descriptions of the detection results, provides help and recommended solutions, and can be directly linked to the source code. The codereview system also provides two sub-modules: metrics: through the execution of the VB Project (VBP, calculate the code length, complexity, comprehension, language usage level, possibility of errors, and other data. namer: it calls a VB project, automatically rename the objects and back up the project files without naming rules, so that developers can manage the programs in a systematic manner.
