Software Testing: Key Considerations for Testers

Introduction

Software defects, if left unchecked, may result in data loss, security vulnerabilities, application downtime, or other issues that impede an organization's ability to conduct business and serve its customers. As a result, testing ensures that software products deliver the level of quality expected by clients and end-users and that they meet all relevant industry standards and regulations.

We are presenting the basics of software testing that can aid a tester in ensuring the proper execution of the testing process. It is advantageous to approach software testing by considering seven fundamental factors, which we will examine below:

Test Strategy

The ultimate goal of testing is to uncover defects in the software that are not immediately obvious. Developing a test strategy involves deciding on the specific testing approaches and techniques that will be used to detect these flaws. The strategy should be based on the requirements for the software and the information that helps understand the customer's needs. By selecting the right test strategy, organizations can save both time and money. It is recommended that test strategy development begins during the design phase to ensure that testing is fully integrated into the overall software development process.

Test Plan

The testing plan is primarily concerned with the tasks of software testing. This important aspect of testing encompasses the specifics including which tasks will be assigned to which individuals, when the testing will begin and end, the level of effort required, and a comprehensive checklist of all testing-related activities that must be performed. The testing plan is instrumental in identifying any key dependencies that exist between various testing tasks, enabling the tester to begin filling out the details of the plan as soon as the test strategy has been finalized. As the project advances, there may be changes to both the testing strategy and plan, requiring regular updates to ensure optimal alignment with project goals.

Test Case

When developing a test case, a tester must prioritize requirements based on the customer's approach and quality goals. It's vital to prepare all test cases before beginning the actual testing, rather than relying on ad hoc methods. The development of test cases runs parallel to software development tasks.

Writing a test case can be just as challenging as programming software. To create an effective test case, testers need to possess a deep understanding of requirements and business rules. Having this knowledge can help testers predict the expected results. Expected results serve as a benchmark in determining whether a test passes or fails. Designing a good test case is essential to detect both visible and hidden defects in the software.

Once a test case has been written, it's crucial to have the appropriate test data to execute it. Test data can include various types of information such as names, addresses, product orders, and other data the system may use. Typically, the development of test data is done in tandem with test case development.

Test Environment

The test environment refers to the location where testing takes place, and it may require a set of equipment to be in place as well. A proper test environment might even require multiple machines. When setting up the test environment, it's best to create a mini-environment that mirrors the environment where the software will eventually run. The planning process for test environment setup includes tips to ensure the environment is appropriately configured and completed before initiating the testing process.

Test Tools

Using testing tools is an essential aspect of software testing. A wide range of tools are available in the market, and using them smartly guarantees that no issues go unnoticed by testers.

Although theoretical knowledge and testing tools can provide valuable insights, they are only as effective as the person using them. It is crucial to work with a skilled and experienced tester who possesses the knowledge and expertise needed to optimally utilize available resources.
