Several users experience bugs or lags while using a software, affecting the overall user experience. Such bugs may be a result of poor testing conducted by a software development firm or an independent developer. Software testing helps developers proactively find and eliminate errors to reduce risks for an end-user. With the help of testing, developers aim to reproduce errors and measure how frequently those errors occur. For this purpose, software development firms follow multiple software testing methods.
Black-box testing is one of the most common kinds of testing. Software development experts aim to discover whether their software itself is a black box. In black-box testing, software developers provide certain inputs and verify whether the desired output is generated. Here, testers and developers are not concerned about the code running in the background or the internal modules of a software. Hence, testers do not focus on how the output was generated or the relationships between the inputs and outputs. Black-box testing can also be conducted by a non-tech person as the testing is carried out from a user’s perspective. In case a tester discovers any errors, it can be increasingly difficult to find the root causes of errors.
White-box testing is quite the opposite of black-box testing. In white-box testing, testers are aware of some of the aspects of internal system. Testers also have access to the source code of a software. For example, a tester can observe various elements of an e-commerce app such as login screen, notifications, check out, and many more. Testers can access different sections of code that are used for various elements. With this approach, developers and testers can design test cases for various scenarios. With white-box testing, developers can understand how the software would respond in different scenarios and discover bugs.
Regression testing is a significant part of agile software development methodologies, where the development process is incremental. In this process, developers frequently add new features, which could affect existing functions of a software. Regression testing checks whether a software still works as it used to after adding new features. Most automated testing involves regression testing. Hence, regression testing is automatically conducted multiple times in the development process. Regression testing involves several testing methods such as functional tests, stress tests, performance tests, and many more.
Acceptance testing or user acceptance testing is conducted by clients or end users of a software. Acceptance testing ensures that a software meets the end-user’s requirements. In acceptance testing, the client tests all the functionalities and features of a software. For this purpose, a software needs to be up and running to exhibit its full potential. Here, developers have to perform the critical task of documenting software behaviour and its response to various user actions. This is one of the final stages of software development and testing where the client may or may not be satisfied by the performance of a software.
Functional testing is a type of quality assurance that tests software outputs against business objectives. Functional testing confirms whether the expected results are received when a specific input is given to the software. Developers also test various technical aspects of a software such as usability, security, performance, and scalability in functional testing. Hence, developers use functional testing to test the overall functionality of their software. For instance, if a developer has created a construction software for building information modeling, they can test how the software will interact with concerned parties, calculate required costs, and offer a glimpse into the final structure. In case the software doesn’t provide desirable results, the developers can look for bugs.
Software developers aim to identify hidden bugs with the help of exploratory testing. In exploratory testing, developers establish some specific guidelines and plan which areas of the software will be tested. Usually, developers explore the entire software application to look for aspects that may be incorrect or buggy. In exploratory testing, developers don’t create any test cases. Instead, exploratory testing sessions are carefully recorded. In case any error is uncovered, the steps leading to that error can be reproduced. With this approach, software development firms try to discover bugs that cannot be found with test cases.
Developers try to analyze the behaviour of a software with the help of performance testing. For this purpose, developers test their software in specific conditions that can put a significant load on the system. With performance testing, developers can analyze the stability and reliability of their software under stressful conditions. For instance, developers may carry out multiple complex calculations on an accounting software to test its full potential. With this approach, developers can understand how their software responds while executing a high number of requests and large volumes of data. Hence, software development firms can test the efficiency and functionality of their software with the help of performance testing.
Integration testing checks whether different modules and services of a software work well together. For example, if a developer is testing a video editing software, they can check how different modules for trimming, lopping, colour grading, and audio work together to create a professionally edited video. Also, this type of testing is especially useful for software with client/server architecture and distributed systems. Integration testing is usually done in a bottom-up or top-down approach.
Even after knowing different software testing techniques, putting them into practice can be increasingly complex. For this purpose, developers need to create a test plan, design test cases, and record results. Hence, business owners have to hire experienced and well-informed developers for enterprise software development. Business owners can reach out to Digital Fractal to work with skilled developers.
