The practice of software testing involves the systematic detection and correction of software flaws. The process is a valuable tool for organizations, enabling them to identify and rectify errors before launching the software, thereby saving costs.

In addition to its financial benefits, software testing can enhance software quality. For instance, if an entity discovers a malfunctioning functionality, it can rectify the issue before deploying the software.

The Process of Software Testing

Similar to any other process, software testing can also be categorized into different phases. This series of phases is commonly called the software testing life cycle. Let us explore each phase below.

• Planning

The beginning of every process is rooted in thorough planning. This phase ensures a complete collation of all pertinent information relevant to the product. The key tasks to be tested are identified and listed.

Understanding the bug and desired behavior is paramount if the testing follows a bug fix. Once the task checklist is compiled, prioritization becomes imperative. Additionally, task delegation is feasible during this critical phase if the project involves a team.

• Preparation

After determining the necessary tasks, the next step is establishing the groundwork for testing. This entails setting up the test environment, compiling relevant test cases, examining product functionalities and test cases, and acquiring the appropriate testing tools and techniques while familiarizing oneself with them. Indeed, this stage is a crucial aspect of the process.

• Execution

During this phase, the product undergoes actual testing, where test cases are executed, and results are collected. A comparison is then made between the outcomes and the expected consequences to verify whether the product functions as intended. The success and failure of the tests and test cases are meticulously documented.

• Reporting

The final stage of software testing requires comprehensive documentation of all identified issues to be submitted to the relevant authority. Test case failures in this phase need particular attention. A thorough record of the tests performed and their resulting outputs is necessary, including clear explanations. After these complex tests, it is essential to include detailed steps for reproducing errors and any helpful screenshots or additional information.

Best Practices of Software Testing                   

Software testing requires several stages, including developing test cases, defining a suitable test environment, analyzing test results, writing scripts, and submitting defect reports. Testing can be time-intensive, but manual or ad-hoc testing may suffice for small developments.

Nonetheless, larger systems require tools that offer automation capabilities, which enable teams to undertake various scenarios and test differentiators, such as those involved in moving components to the cloud environment. Automated testing delivers prompt feedback on what works and requires improvement, making it a practical approach for software testing professionals.

A comprehensive approach considering the application programming interface (API), user interface, and system levels works to ensure effective testing. An increased number of automated tests conducted earlier in the development cycle leads to improved outcomes. Specific teams choose to develop in-house automated testing tools, while others opt for vendor solutions that offer features that can streamline vital test management activities, including:

• Continuous testing

Project teams implement a thorough testing strategy in software development by conducting automated tests at every build release. This approach integrates testing with the deployment process, offering a more realistic testing environment for early-stage software validation. By adopting this method, software design is enhanced, and potential risks are significantly reduced. It is a vital component of the software development lifecycle.

• Configuration management

Test assets are managed by organizations at a centralized location, allowing for easier tracking of software development that requires testing, enabling teams to access critical assets, including code, design documents, requirements, test scripts, and results. Well-designed systems provide user authentication and audit trails, which help teams ensure compliance with minimal administrative intervention.

• Service virtualization

Testing environments may not be readily accessible, particularly in the initial stages of coding, so service virtualization provides a feasible solution by emulating services and systems that are either unavailable or not yet finalized. This facilitates the early testing of code and minimizes dependencies. Furthermore, the team can efficiently reuse, deploy and alter configurations to examine various scenarios without modifying the original environment.
