Having a working website can solidify a company's presence and image in the digital space. With web testing, developers can help ensure the functionality of a website before releasing it to the public. If you work as a developer or are interested in web development, understanding what web testing is can be helpful for building effective web pages for companies. In this article, we answer "What is web testing?" and outline and discuss the various types of web testing with examples.
What is web testing?
If you're interested in web development, you may have wondered, "What is web testing?". Web testing is the process of taking your web-based application or website through a series of trials to assess its functionality, measure its quality, assess for bugs, and evaluate its performance before giving access to the intended target audience. This procedure aims to identify issues that may interfere with a memorable user experience regarding a site's adaptability to mobile devices or PCs and its ability to accommodate a surge in user traffic.
Types of web testing
Web testing can help ensure that a website or software works the way you intend while meeting user requirements. There are certain approaches you can apply to validate the efficiency of a website or software. These include:
Functional testing is a type of web testing that helps validate the integrity of every individual function and help ensure they work for the website's requirements. Functional testing can evaluate the response of the components of the system. You can use this approach to cross-check that the website functions or performs how you intend it to, considering hardware and user specifications. You can perform these tests manually with a human tester's assistance or automatically with the aid of software. Some examples of functional web testing are:
User acceptance and alpha testing: This type of functional test requires a defined set of users to determine whether the purpose of a web application aligns with their primary needs and how to improve it if necessary. It ensures that the final product meets the expectation of the end-user.
API testing: API stands for Application Programming Interface. It's a type of functional test that validates the efficiency, reliability, and security of the website.
Beta testing: Beta testing is a way to identify bugs in a web-based application that the developers may have ignored. This process typically involves giving access to the website or software to a small group of people with no previous knowledge of it in the hope that they can provide feedback on how to improve it or identify bugs that interfere with a good user experience.
Black box testing: Black box testing involves testing a system from the viewpoint of an average user. It's any test that doesn't require knowledge of the internal structure of the website to determine or assess its functionality.
Component testing: Also called module testing, it involves assessing the individual parts of the software.
Integration testing: Integration testing is a way to verify that every individual component of the software works well collectively with the rest of the system.
Product testing: Product testing is a form of continuous testing that relies on the feedback and report of the target audience to confirm the functionality, stability, and efficiency of the software.
Smoke testing: Also known as build verification testing, it's the test that developers use to determine if the functionality of the website meets its primary objective.
Sanity testing: The sanity test is a type of regression test that helps developers determine that a bug fix or code change doesn't interfere with the fundamental objective of the website.
System testing: This is a type of functional test where developers test the integrity of each component as a complete product to make sure that the software meets the intended requirement. Developers may also refer to it as end-to-end testing.
Regression testing: It's a test done to help ensure that the stability of the software or website remains the same, even with a change in code, program, or feature.
Unit testing: Unit testing is a type of functional test that checks for the function of a lone component of the website, ensuring that it produces the desired results every time a user makes the same input function.
UI testing: UI stands for user interface. It's the space the user may interact with to use a digital product or service. UI testing involves checking for the response of buttons, menus, and text input to help ensure a seamless user experience.
White box testing: This involves testing the internal structure of the website to help ensure it responds appropriately to pre-defined inputs. It verifies the codes, programs, and other essential data structures that run the entire system.
A usability test is a way to determine the efficiency of a website or web-based application by watching end-users leverage it to meet their primary goals. A usability test aims to gather data on the behavioural response and reaction of a user when using a digital product. Doing this can help developers identify potential problems, confirm if the product meets expectations, and improve the overall user experience.
Interface testing is a web test that determines the efficiency of communication between software systems. This test can help ensure that end-users have a smooth and problem-free experience when using the software product. Interface testing often involves assessing:
Webserver and application server interface
Application server and database server interface
This is a type of software testing that checks for the responsiveness of the website's database. Also known as backend testing, it mainly entails evaluating data integrity, schema, tables, or triggers. It can be an important procedure because it helps remove errors from the database and helps ensures the maintenance of the quality of data. It can also help verify that certain scenarios, like network issues and power outages, don't lead to data loss.
Some of the database testing tools you can consider are:
Java Database Delta Testing
A compatibility test checks the adaptability of the website for different hardware, operating systems, applications, and network environments. There are four different types of compatibility testing:
Software testing: This process concerns operating systems (OS). It may include forward testing the website on newer versions of the operating or backward testing the website on previous versions of the OS.
Hardware testing: This involves checking the website for compatibility with different processors, RAM, and graphics cards.
Network testing: This type of testing involves checking for compatibility with different network parameters like speed, bandwidth, and capacity.
Mobile testing: This testing involves checking usability, compatibility, and functionality with different mobile versions of applications or websites.
Developers typically use performance testing to assess the overall performance of the website in terms of responsiveness, effectiveness, stability, and scalability under a particular workload. Some of the types of performance tests are:
Load testing: Load testing is a non-functional software evaluation procedure that assesses a site's efficiency under a certain workload. It evaluates how the website performs when several users access it at the same time to minimize performance issues and help guarantee platform functionality before deployment.
Stress testing: During stress testing, developers monitor the website after exposing it to overload to check whether it can endure the stress. The platform's recovery from such a situation is vital, as it often illustrates what may likely occur in a real-life context.
Endurance testing: Endurance testing is a method of non-functional evaluation where developers test a website under heavy load for a prolonged period to determine its responsiveness and behaviour during extensive use. The primary objective of an endurance test is to help ensure that the website can withstand increased load without reducing response time.
Scalability testing: This is a non-functional testing approach for determining how well a system or network performs when the number of user requests increases or decreases. This test helps verify that a platform can accommodate a forecasted rise in user activity, data size, and rate of transaction counts.
Developers use this type of web test to identify the blind spots and vulnerabilities in the website. It's a form of ethical hacking where developers probe through the website in search of any element that may grant intruders access to the data and resources on the platform. Some examples of security testing are:
Crowd testing, also known as crowdsource testing, is a process where developers release the platform to expert or beta testers who perform their evaluations under real-life conditions. This approach allows more people to engage in the testing phase, with greater flexibility and usually at less cost to a company. This test often requires a shorter wait time than traditional in-house tests.
