Software testing tools are required for the betterment of the application or software.
That’s why we have so many tools available in the market where some are open-source and paid tools.
The significant difference between open-source and the paid tool is that the open-source tools have limited features, whereas paid tool or commercial tools have no limitation for the features. The selection of tools depends on the user’s requirements, whether it is paid or free.
With the help of testing tools, we can improve our software performance, deliver a high-quality product, and reduce the duration of testing, which is spent on manual efforts.
The software testing tools can be categorized, depending on the licensing (paid or commercial, open-source), technology usage, type of testing, and so on.
Test management tool
Test management tools are used to keep track of all the testing activity, fast data analysis, manage manual and automation test cases, various environments, and plan and maintain manual testing as well.
Bug tracking tool
The defect tracking tool is used to keep track of the bug fixes and ensure the delivery of a quality product. This tool can help us to find the bugs in the testing stage so that we can get the defect-free data in the production server. With the help of these tools, the end-users can allow reporting the bugs and issues directly on their applications.
Automation testing tool
This type of tool is used to enhance the productivity of the product and improve the accuracy. We can reduce the time and cost of the application by writing some test scripts in any programming language.
Performance testing tool
Performance or Load testing tools are used to check the load, stability, and scalability of the application. When n-number of the users using the application at the same time, and if the application gets crashed because of the immense load, to get through this type of issue, we need load testing tools.
Cross-browser testing tool
This type of tool is used when we need to compare a web application in the various web browser platforms. It is an important part when we are developing a project. With the help of these tools, we will ensure the consistent behavior of the application in multiple devices, browsers, and platforms.
Integration testing tool
This type of tool is used to test the interface between modules and find the critical bugs that are happened because of the different modules and ensuring that all the modules are working as per the client requirements.
GUI testing tool
GUI testing tool is used to test the User interface of the application because a proper GUI (graphical user interface) is always useful to grab the user’s attention. These type of tools will help to find the loopholes in the application’s design and makes its better.
Security testing tool
The security testing tool is used to ensure the security of the software and check for the security leakage. If any security loophole is there, it could be fixed at the early stage of the product. We need this type of the tool when the software has encoded the security code which is not accessible by the unauthorized users.

Forward Engineering
Forward engineering is a process of obtaining desired software from the specifications in hand which was brought down by means of reverse engineering. It assumes that there was some software engineering already done in the past.
Forward engineering is the same as the software engineering process with only one difference it is carried out always after reverse engineering.
The forward engineering process applies software engineering principles, concepts, and methods to recreate an existing application. In most cases, forward engineering does not simply create a modern equivalent of an older program.
Rather, new user and technology requirements are integrated into the reengineering effort.
The redeveloped program extends the capabilities of the older application.
The example of forward engineering is the construction of electronic kit, construction of DC MOTOR , etc.
Reverse Engineering
Reverse engineering can extract design information from source code, but the abstraction level, the completeness of the documentation, the degree to which tools and a human analyst work together.
The directionality of the process are highly variable.
The abstraction level of a reverse engineering process and the tools used to effect it refers to the sophistication of the design information that can be extracted from source code.
Ideally, the abstraction level should be as high as possible.
That is, the reverse engineering process should be capable of deriving procedural design representations (a low-level abstraction), program and data structure information (a somewhat higher level of abstraction), object models, data and/or control flow models (a relatively high level of abstraction), and entity-relationship models (a high level of abstraction).
As the abstraction level increases, you are provided with information that will allow an easier understanding of the program
The completeness of a reverse engineering process refers to the level of detail that is provided at an abstraction level. In most cases, the completeness decreases as the abstraction level increases.
Interactivity refers to the degree to which the human is “integrated” with automated tools to create an effective reverse engineering process.
In most cases, as the abstraction level increases, interactivity must increase or completeness will suffer.
The directionality of the reverse engineering process is one-way, all information extracted from the source code is provided to the software engineer who can then use it during any maintenance activity.
An example of backward engineering is research on Instruments etc.
