All You Need to Know About Computer Aided Software Testing (CAST)

Computer-aided software testing: a Simple definition of CAST

Computer-aided software testing (CAST) refers to the use of software tools that automate the process of software testing. The term 'software testing' is generally used interchangeably with the term "software quality assurance" or "software quality control". Any kind of automated test can be classified as a CAST test, although there are other types of testing.

Computer Assisted Software Testing (CAST) has become a popular alternative to manual testing. CAST tools are used to automate the process of testing software application to save time and money. These automated tools can help developers test their web applications without having to invest in human resources or spend too much time on each application.

What are CAST tools?

CAST tools are specialized software applications that provide automated assistance in testing software programs. The purpose of a CAST tool is to isolate required functionality, test it, and check it for defects. A CAST tool can be used in conjunction with manual testing and can also replace it in some cases. CAST tools are intended to be used as a complement to manual testing, not as an alternative. They can automate the tedious parts of manual testing and provide results that are useful for decision making. For example, if you are using CAST software and discover a bug in your web application, you can immediately start fixing it and submit the patched version back to your clients.

CAST tools have become very popular because they speed up development time and reduce costs. Manually testing every application is not only labour-intensive but also expensive as one needs to hire software testers. CAST tools allow software engineers to save both time and money by automating the software testing process, which eventually helps them to get more done for less money.

Nowadays, Software development companies are highly adopting automated testing tools in order to provide a quality products to the customers. To ensure seamless and efficient execution of test cases, a software engineer can use these testing tools.

Software testing tools can be categorized into the following types:

Functional testing tools: These tool types help QA teams test the functionalities of testing software applications. Functional testing tools include requirement testing tools, code reviews, regression testing tools, and test design tools.

Non-functional testing tools: These types of tool categories help QA teams perform non-functional tests like load testing, performance testing, security testing, etc. Non-functional testing tools include static analysis tools, static analysis tools, character-based testing tools, UI testing tools, test data preparation tools, performance testing tools and GUI testing tools.

Manual testing is a time consuming and laborious process. It is also an expensive one. So, to reduce manual efforts and time, automation testing tools are used in the industry.

Following are some of the advantages of using automated testing tools

Better Efficiency

‍Automated testing tools help teams to organize their work effectively and create a better workflow. The automated tests can be run at any time with just one click on the button. This increases the efficiency and productivity of the teams as well as reduces costs.

Less Human Errors

‍Automated tests cannot make mistakes as any human tester can do while executing the test cases manually. These tools record all the steps executed, including every input and output, displayed at all times during execution. If there is any bug or error, it can be traced easily with all the details available in a test report.

Execute Tests Faster

‍Using automation frameworks, Software engineers can execute tests much faster than manual tests which require more time for execution. With automation tools, one can execute hundreds or thousands of tests within the same amount of time that it would take to execute manual tests.

Types of Computer-aided software testing Tools

  1. Requirements testing tools – They identify the requirements of testing software applications, including the functional and technical requirements. Such tools also analyze requirements, define scope and traceability, etc.
  2. Regression testing tools – They are used to test the software components that have been modified, to ensure that they work as expected.
  3. Test design tools – help in the creation of test cases and test scripts.
  4. Static analysis (also called static code analysis or SAST) tools – automatically analyze the source code against a defined rule set. These tools are often used as part of a CI/CD process, to prevent code containing known security vulnerabilities from being deployed in production.
  5. Character-based testing tools – check whether character-related functionalities like sorting, aligning, printing, etc., are working as expected.
  6. UI testing tools – checks whether the UI (User Interface) of an application is working fine or not. These tools can be used for checking buttons and links on web pages, verifying whether an API call is returning the correct response or not, etc.
  7. Test data preparation tools – These tools help in creating test data for automation testing by populating databases with required records or files with the required content.
  8. Performance testing tools – They measure the performance of an application under load against various parameters like: response time of an application, and stability of an application on different operating system platforms.
  9. Dynamic analysis tools – These tools analyze the software during execution or a program’s run-time behavior. The results of testing through dynamic analysis tools are generally presented in the form of tables, graphs, and charts that help testers and developers visualize the behavior of an application.
  10. Comparison tool – These tools compare files, folders, databases, source code, and other data to find differences between them.
  11. Debugging tool – Debugging is a process that involves the detection and removal of errors from a program’s source code. Debugging tools help with these processes by enabling programmers to find errors in their code and then fix them.
  12. Functional testing tool – Functional testing is an important part of software verification and validation processes and aims to ensure that the program functions as expected by comparing its actual output with the expected output.

How Do CAST Tools Work?

For many businesses, computer-aided software testing is an essential part of the development process. By using automated test cases, developers can create standardized tests that will be run each time any changes are made to an application's codebase. These types of tests help developers avoid problems like untested code and broken features when applications reach the point where they need to be released to users.

What are CASE tools and why they are important in the software development process?

CASE tools are important for the management of software development projects. They provide the project manager with a way to manage not just the development process but also the people that are involved in it. Case tools can be classed into categories such as; software design tools, requirement-analysis tools, code-generation tools, document product tools, etc. 

A computer aided software engineering tool helps to keep track of how much time is being spent on each task. This helps to identify where improvements can be made, and where the project development team should be focusing on. The best advantage that comes with CASE tools is that they are completely automated. This means that developers do not need to spend hours manually entering data into them. Instead, they automatically update everything for the entire development process.

CASE tools provide software project managers with an efficient means for tracking changes and bugs in the code that a team is working on. This can make it much easier for a software development team to identify potential problems before they become serious ones, and ensure that the developers can focus on fixing these problems rather than trying to figure out what went wrong in the first place.

How Businesses can benefit from using computer aided software testing tools (CAST) 

Computer-aided software testing (CAST) tools provide ways to help businesses test software. Businesses can use CAST tools to make sure their software is working properly and meets the needs of users.

Businesses can benefit from using CAST tools in the following multiple ways. 

  • The ability to write tests at the same time as coding
  • The ability to write tests that are easy to understand and maintain
  • More efficient test runs through automation
  • A reduction in errors due to manual data entry, more efficient testing and more accurate results
  • An increase in productivity thanks to easier testing and a faster pace of development.

How businesses and companies benefit from Software quality assurance 

Software quality assurance is a particularly important part of the development process at most companies. The way we do things today is different from what it used to be even a few years ago.

In the past, software testing service and quality assurance were often viewed as an afterthought in the product development process. They were often seen as a separate department, with different goals and priorities than the rest of the organization. This separation only added to the disconnect between developers and testers, often leading to a situation where testers were left out of the loop or left to deal with rushed quality assurance processes that did not allow them to do their job effectively.

This approach is no longer effective in today's highly competitive business environment where speed, innovation and customer experience are important factors when it comes to success in software development. As we've seen from recent studies and surveys, there are several advantages that companies gain from investing in quality assurance processes.

For most businesses, the modern IT landscape is a nightmare. There's the ever-present threat of hackers and data breaches, not to mention dealing with the constant changes in technology that have to be implemented across all departments. For companies that have legacy applications that are built on older software platforms, this can be an even bigger problem. They need to keep their existing infrastructure working or risk losing market share from dissatisfied customers or being exposed to cybercriminals looking for an easy mark. However, businesses that are willing to take the plunge and invest in computer-aided software testing tools will reap many benefits from doing so, including increased productivity and reduced costs.

What are some of the benefits of using CAST tools in the software development process?

  • CAST tools allow the user to automate operations and processes that can be time-consuming when performed manually.
  • The use of CAST tools keeps manual testing from becoming too costly while helping to ensure that the software application performs at optimal levels.
  • CAST tools give the software tester more insight into how the software application operates, and what potential problems may exist in terms of memory management, CPU performance and other factors.
  • CAST tools can deliver comprehensive reports on their findings that can be used for future software development projects.
  • These tools can provide real-time analysis regarding the performance of a software application as it is being tested.
  • These tools are designed to help QA teams perform secure and efficient automated software testing.
  • CAST tools enable software developers and testers to quickly create and execute test cases for any type of software application, whether it is a desktop application, a web-based application or a mobile app.
  • CAST tools play an imperative role in the continuous integration process and agile development methodologies by automating the repeatable parts of the testing process.
  • CAST tools allow us to measure code quality and identify weaknesses that can lead to defects and poor performance.
  • These tools provide a mechanism for organizing and maintaining metrics data, sharing data across geographically distributed development teams, and for reporting on metrics over time.
  • CAST provides a centralized management tool that can be configured to support development processes, source code repository structures, and organizational structures.
  • They provide automated analysis of source code to extract software measurements in a repeatable way without manual data entry or sourcing from disparate systems.
  • These tools provide consistent measurement across development efforts using the same tooling platform. This is critically important for organizations with distributed development teams working on different aspects of the same application.

Computer aided software testing tools help software development managers and the development management team to:

  • Increase team productivity and quality of work.
  • Manage changes in a better way and control change impact on software quality.
  • Reduce project risk with proactive & predictive quality assurance programs.
  • Incorporate best practices into the software testing process through automated testing tools.
  • Provide real-time visibility into the latest test results, broken down by project phase, application and test type so that they can track all progress against the project plan in real-time.
  • Cope up with the changing business priorities & release schedules by leveraging automation to reduce the amount of manual effort required to verify each build.
  • Assigning tasks and managing resources – these tools often assign tasks to testers, and track who is working on what task, and their progress. Managers need to assign complex projects to individual coders so they know exactly who is responsible for what tasks. A computer aided software testing tool makes it easy to assign tasks and monitor progress throughout the day, so managers know exactly what’s going on at all times.
  • Raise defects – allowing testers to raise defects from within the tool provides a central repository for all problems. Software development team managers can also track which tester raised the defect, when it was raised, and who is dealing with it.
  • Track test coverage – being able to see which tests have been run against certain pieces of code helps Software development team managers to ensure that they are covering everything that needs to be tested.
  • Report on progress – this is where management often get their information from, the ability to generate reports on progress is essential to every Software development team manager. They can set up alerts in case there are any problems with code or if the project seems like it’s going off track. This enables managers to take action before it becomes too late or too expensive to do so.

Bottom line

Computer based Testing is one of the best testing techniques in software development. It has helped many organizations to increase the efficiency and productivity of their data and system processes for software testing. It features a technology-driven environment with the help of common project management tools and various automation tools, which assist the developers in improving the quality of their software products.

Computer Aided Software Testing is the future. It's a proven fact that the cost of software testing can be halved quite effectively with these programing tools. With the popularity of software engineering and internet connections, there are online tools and techniques to help people who need to test their applications. Everything from testing functionalities to compatibility on multiple OS platforms can be tested with existing tools at a quarter of the price.

In summary, we can say that utilizing computer aided software testing tools bring a lot of benefits to organizations. A good testing tool can help teams and individuals to achieve their goals effectively.
