Testing is a fundamental challenge when developing web applications. Different browsers, interfaces, security threats, and overall app integration are just a few of the issues faced by developers. Since testing is a crucial phase in the development process, the developer should expect to run into unforeseen issues associated with both the web application, and the testing process itself. Each primary issue associated with testing has the potential to branch into uncountable related issues, all of which can be solved if properly identified. Below are five web application testing challenges faced by web developers during the development process.
Integration
Integration testing exposes problems with interfaces among different program components before deployment. Additionally, integration testing can show the different issues an application may have when interacting with other applications, allowing the developer to tweak things. Environment and infrastructure inconsistency, different interaction models, and overall performance are just a few of the issues associated with integration testing.
Interoperability
Proving end-to-end functionality between communicating systems is always a challenging obstacle. Different users utilize different browsers and operating systems. To pull data, testing each one to confirm a clear information pathway is very important. Even if the browsers are similar, the web application may be rendered differently based on screen resolution and overall software configuration. This can present some serious issues for developers.
Security
In one of the most important tests, the developer must make sure that the continually evolving cyber threat can be countered and neutralized. Additionally, tests associated with data integrity before and after an attack are equally important when considering data breaches or lost information. Some of the challenges associated with security testing include dealing with unsecured communications, removing malicious files (if security firewalls have been breached), and the utilization (and integration) of different authentication procedures.
Performance
Slow applications are not successful. Developers understand that the speed of the app is defined by the need of the user, and with more users expecting more speed, the requirement of performance is non-negotiable. Testing large applications on minimal hardware, underestimating software requirements, and overextending application features are just a few of the issues associated with performance testing. Integration and interoperability issues can also have a direct effect on performance, and because of that, should be tested at the beginning.
Usability
Since web-based applications are dependent on different browsers, consistent usability is crucial. Additionally, since the app is the brand (or a component thereof), any inconsistency within the user experience may translate into a negative experience, affecting the brand and its potential growth. When testing usability, developers face issues with scalability and interactivity. Since every user is different, it is important for developers to utilize a representative group to test the application across different browsers, using different hardware.
The testing process is inherently full of issues, but each issue faced by the developer is one less that will be faced by the user. In app development, the first interaction with the app needs to be as flawless as possible, allowing the user to adopt and use the app in a way that is as effortless as possible. By testing integration, interoperability, security, performance, and usability, developers will be better able to identify and manage the actual issues associated with the app. In the end, it is about a positive user experience.
