As developers create working software, using agile methodologies has become the standard during the development process. Through Continuous Integration (CI) and Test Driven Development (TDD), testing while building working software will result in a working product that meets the highest standards for users. Along with a more satisfying user experience, agile working provides the flexibility teams need when testing software and creating a reliable product.

Here are four of the top testing techniques and tools that are essential when building working software.

Building Quality Software

Unit Testing/Integration Testing

Agile developers often use unit testing to test the smallest components of code as singular units within the system. To ensure functionality and avoid faulty code, developers must perform unit testing after each code modification. This allows projects to advance to the next development cycle without faulty code causing disruptions that negatively impact teams and the company's reputation. Neglecting this testing technique can result in bad code being detected at a higher level of development, missed deadlines, and faulty software being released into the market.

Integration testing is an extension of unit testing that combines two coding units after initial testing of each unit individually. This method determines how well the units operate together.

Top tools for unit testing include Junit, Mockito, and xUnit.net.

Security Test

Security testing addresses hacking threats by protecting an application against unauthorized code that could delete, change, or steal sensitive information. Data protection is the main objective of security testing, which requires countermeasures such as firewalls and antivirus programs.

During security testing, systems are scanned and tested for vulnerabilities. Penetration testing is a common method of exposing these weaknesses by attempting to break into the system using the same techniques as cybercriminals. Risk assessment can also be carried out at an organizational level, classifying security threats as low, medium or high before implementing measures to effectively reduce risk at all levels.

Top tools for security testing include Netsparker , Nmap , and Metaspoilt .

Testing usability

Investing in developing a product that users won't like is a waste of valuable company resources. To avoid this costly mistake, perform usability testing before a product goes to market.

Usability testing depends on the experience front-end users have when testing a specific function of an application or using the entire application. As users test the app, their feedback helps researchers diagnose usability issues and confusing elements that result in a negative user experience.

The next step is to determine how to resolve these conflicts during development. Usability testing gives back-end developers more perspective regarding customer needs, and they use these customer-centric insights when building a product that is more likely to be successful and that encourages customer loyalty.

Top tools for usability testing include Optimizely, BrowserStack, and Usability.

Compatibility Test

Compatibility testing is crucial because it ensures that the software works in diverse environments. Application compatibility must be tested because applications must work across platforms to provide the best user experience, regardless of the user's operating system.

Compatibility testing is performed at the end of the development process, but the possibility of bugs remains. When bugs are detected during compatibility testing, you must retest compatibility after fixing the bugs to confirm that the application still works with the different configurations.

Top tools for compatibility testing include BrowserStack, SeeTest, and Browsera.

Using the right testing tools and techniques results in a successful product

Meeting the demands of today's application users requires the right testing techniques and tools to differentiate your product from the competition. As new technologies continue to emerge, software development must focus on high-quality, innovative products. Therefore, attention to detail and quality assurance are necessary when testing software. Before presenting a new application to the public, functionality, ease of use and security are features that must work at all times, while still gaining relevance and trust in the current competitive market.
